When loading or unloading the machine onto or off of a cart or dolly, utilize appropriate lifting equipment or manpower to avoid damage to the machine or personal injury. Note: To avoid injury or death from an electrical insulation breakdown within the unit, the GFI (ground fault interrupter) circuit breaker should be checked for proper operation on an annual basis. Note: If during the use of this equipment you see or smell smoke, immediately disconnect the unit from the power supply, discontinue use and call MEDIVATORS Technical Support at CER OPTIMA Service Manual

7 Note: Prior to undertaking any service or maintenance operation, or when resetting the GFI ensure that the CER OPTIMA is disconnected from the main power supply. If service or maintenance operations are to be conducted on the water system, ensure that the CER OPTIMA is isolated from the main water supply. Warning! The reprocessor must be protectively grounded. Installation and Maintenance For complete system installation instructions and details, refer to the: CER OPTIMA Pre-site Installation Instructions CER OPTIMA Water Filtration Installation Instructions CER OPTIMA Installation Instructions Upon installation, position the equipment so the power on/off switch is readily accessible by the operator. Ensure compliance with the installation documents before operating the system. The reprocessor must be properly grounded. The disinfectant immersion period (contact time) is fixed in the CER OPTIMA s software, specific to the high level disinfectant that is displayed on the screen at the start of the cycle. All pressure regulators are factory-preset. Do not adjust the settings. Contact MEDIVATORS Technical Support for assistance. Do not use alcohol or alcohol-based products to clean the reprocessor cabinet. The hook-ups are not autoclavable and must be reprocessed by low temperature disinfection only. Replacement parts must be ordered from the manufacturer to maintain the warranty. Regularly inspect reprocessor for basin damage, pipe and tubing damage, which may result in leaks. Ensure CER OPTIMA unit is level prior to operation. Place a bubble level on the front and side edges of the basin. Level the unit using the four (4) adjustable feet on the bottom of the reprocessor. To adjust the level of the reprocessor, rotate the foot clockwise to raise up, or counterclockwise to lower the corner. When the basin is full of liquid, the level of the liquid should be even around the top of the basin. Proper maintenance will ensure effective disinfection and prolong the life of the reprocessor. CER OPTIMA Service Manual 7

8 Water Quality and Filtration Potable water is the minimum standard. Incoming water must be pre-filtered to a minimum of 1 micron. Use a cold water line with a pressure of 40 to 60 PSI that will supply a flow rate of 2.5 to 3 GPM (9.4 LPM to 11.4 LPM) to the water filtration system. The cold water supply should not exceed 104 F (40 C). The high performance 0.2-micron absolute water filter included with the reprocessor is a bacterial-retentive filter. This filter removes all microorganisms and particles greater than 0.2-micron. The routine maintenance schedule recommends replacing the 0.2-micron water filter every 6 months or sooner, depending on the pre-filtration system and the quality of the incoming water. Never use a nominal 0.2 micron water filter. Incoming water supplied (upstream of the external pre-filtration system) should be shut-off at the end of every work day. Ensure this water supply is turned on prior to operating the reprocessor. The pre-filtration system should be monitored for excessive pressure drop indicating blocked filter membranes. If this occurs replace the water filter. Chemicals The CER OPTIMA is designed for use with RAPICIDE High-Level Disinfectant, Glutaraldehyde disinfectant, or Ortho-phthaladehyde (also known as OPA) disinfectant. Refer to the American National Standard recommended practice titled, Chemical Sterilants and High Level Disinfectants: A guide to Selection and Use (AAMI TIR7:1999) and/or Safe Handling and Biological Decontamination of Reusable Medical Devices in Health Care Facilities and in Nonclinical Settings (AAMI/ANSI ST35:2003). These documents are available from the Association for the Advancement of Medical Instrumentation. The CER OPTIMA also allows the use of detergents for endoscope washing, or 70% Ethyl Alcohol and Isopropyl Alcohol for end-of-cycle endoscope drying. For all chemicals used within the CER OPTIMA, refer to the respective chemical labeling, directionsfor-use (DFU) and/or material safety data sheet (MSDS) for chemistry constituents, as well as for safety and handling guidelines. These documents should be displayed and stored near the CER OPTIMA for easy access in the event of a chemical spill or emergency resulting in contact with any chemical that is considered hazardous. In case of an emergency in which eye or skin contact, or inhalation occurs, such as release of toxic or pathogenic material, or leakage from a disinfectant container, or detergent (alkaline, acidic, non-enymatic or enzymatic) container, always refer to the manufacturer s labeling, directions for use and/or Materials Safety Data Sheet (MSDS), for first aid measures, accidental release measures and exposure controls/ personal protection. Call the emergency telephone number located on the MSDS if additional manufacturer s information is needed. Detergent Solution If the user decides to incorporate a pre-wash in the reprocessing cycle, MEDIVATORS recommends the use of a medical-grade detergent solution which is bacteriostatic, low foaming, free-rinsing and having a neutral ph. 8 CER OPTIMA Service Manual

9 ! Caution! Never use household detergent in the reprocessor. Disinfectant Solution The CER OPTIMA is designed for use with RAPICIDE High-Level Disinfectant (HLD), Glutaraldehyde HLD, or Ortho-phthaladehyde (also known as OPA) HLD. MEDIVATORS only recommends the use of the HLD that is legally marketed and FDA cleared as a highlevel disinfectant/sterilant for use on flexible endoscopes and medical devices/instruments. Refer to the FDA website to confirm the HLD is cleared for use. It is the user s responsibility to ensure the HLD is used per the disinfectant manufacturer s instructions, including the proper contact time, use temperature, and post rinses. Refer to the high level disinfectant manufacturer s directions for use for further instructions. Monitoring Disinfectant Potency High Level Disinfectant (HLD) testing must be performed before each reprocessing cycle. The minimum required concentration (MRC) testing of the high level disinfectant (HLD), ensures the HLD is at an effective level of potency, so that it can be used to disinfect an endoscope or medical device. Testing the potency prior to starting a reprocessing cycle, confirms the disinfectant s MRC potency, and that it can be used to achieve high level disinfection of an endoscope or medical device. Use only the disinfectant manufacturer s recommended test strips to test the potency of the HLD. If the high level disinfectant is below the minimum required concentration, then discard the used disinfectant and replace it with new disinfectant, prior to initiating a reprocessing cycle. Refer to the test strip manufacturer s instructions, for further details and step-by-step use instructions. Endoscope Precleaning and Testing All endoscopes must be manually precleaned prior to disinfection. Follow the endoscope manufacturer s instructions and established professional guidelines to properly preclean the endoscope. Endoscopes with elevator wire channels require additional manual cleaning and disinfection steps. Leak test endoscopes prior to disinfection procedures. CER OPTIMA Service Manual 9

11 The online hookup guide is available at: Refer to the online hookup guide for additional notes and considerations specific to individual endoscope models. Endoscopes must be thoroughly cleaned according to the manufacturer s instructions and established professional society guidelines prior to hookup connection. Failure to properly clean and prepare endoscopes may result in inadequate high level disinfection and/or damage to the endoscope. Endoscopes must be inspected for damage and verified to be in proper working order prior to hookup connection. If cleaning or leak testing identifies endoscope damage or channels that may be restricted or obstructed, the endoscope should be repaired before further reprocessing. Connection of hookups to damaged endoscopes, or endoscopes with restricted or obstructed channels may result in inadequate high level disinfection. Users operating MEDIVATORS AERs and hookups must be trained and competent in the understanding of endoscope channel systems. Prior to hookup connection, users must verify that the hookup used contains connections for all appropriate endoscope channels that require a separate reprocessing connection. Ensure proper alignment of all connectors with the endoscope mating parts prior to attachment. Misalignment may cause damage to hookup components and/or mating parts. All connectors and adapters must remain firmly attached and unrestricted for the entire disinfection cycle to ensure adequate high level disinfection. Users must inspect the endoscope and hookup combination to verify proper connection and flow. Remove connectors from mating parts by gripping the connector directly and detaching from the endoscope. Do not remove connectors by pulling on tubing. Hookups must be periodically checked to ensure their functionality is not impaired. Hookups should be inspected for damaged or worn connectors, missing components, kinked/blocked tubing or other signs of deterioration. If signs of damage or deterioration are found, the hookup should be replaced. Modifications or repairs to hookups which do not correspond to the manufacturer s specifications may result in inadequate high level disinfection and/or damage to endoscopes. Leak testing should be carried out in accordance with endoscope manufacturer s recommendations prior to hookup connection. Install all necessary waterproof caps, plugs and cleaning adapters prior to immersion. Do NOT autoclave MEDIVATORS hookups. Avoid biological contamination. Always wear personal protective equipment when handling endoscopes.

34 Channel Pump The CER OPTIMA internal channel pump performs various duties in the cycle of the reprocessor. The pump pushes fluid through the endoscope connectors during various phases of the cycle and also assists the disinfectant back to the reservoir and rinse water to the drain. Please note, the pump only assists and draining is dependent on gravity. The pump is not designed to pump fluid higher than the bottom of the reprocessor. This is the reason that the reservoir return hoses and drain lines must go down from the back of the machine, and never loop above the drain fittings. The Channel pump is a 120VAC pump that has two line fuses in the chassis. Refer to the section on fuse replacement for further details Channel Pump Replacement 1.

38 CER OPTIMA Alcohol System The CER OPTIMA Alcohol system is comprised of a perastaltic pump, which pumps alcohol into the manifold for distribution to the individual basin connectors. The alcohol is drawn out of the alcohol container located at the left front corner of the machine behind a small access door. The flow of alcohol is monitored by a proximity sensor. The sensor will trigger a Low Alcohol Alarm when no alcohol is detected, indicating the alcohol bottle is empty. Perastaltic Pump The Perastaltic pump is comprised of a length of tubing located in the pump head housing. The tubing is squeezed by a rotating cam in the pump head housing. The cam action on the tubing creates suction and pumping motion that transports the alcohol from the holding bottle to the manifold. To Access the Pump The pump is located behind the left side access panel. Power down the reprocessor, remove the six retaining screws and remove the cover plate. See figure 16. Hose to main manifold Hose from alcohol supply bottles Perastaltic pump Figure 16 Pump tubing 38 CER OPTIMA Service Manual

44 Error and Warning Messages Error messages are displayed on the LCD screen to alert the operator of operational malfunctions and/or operational warnings (see the Appendix for message definitions). If the suggested solutions do not correct the problem or if the problem reoccurs contact customer support. LOW WATER LEVEL - If the basin is NOT full of water at the time of the alarm Problem Solution Incoming water pressure is too low Verify water pressure is between 40 and 60 PSI: This pressure must be present at the post (0.2µ) filter of the filter unit, see figure 20. The CER OPTIMA is designed to operate within this pressure range. Water pressure outside of this range can cause operational errors. If pressure is outside this range, contact a qualified plumber to obtain water pressure within this range. If using pressure regulators or booster pumps, these devices require periodic (typically yearly) maintenance to continue to operate at optimum specifications. Water Filters clogged Replace water filters: To verify if the filters are clogged, a simple check of the pressure differential is made. The pressure differential must be checked when water is flowing (Dynamic pressure). Even with clogged filters, if pressure is checked when no water is flowing (Static pressure), the water pressure can appear to be correct, but is not. To check the pressure, simply start a cycle and observe the three pressure gauges during the initial fills. If the pressure differential from the first to the last gauge is greater than 5 PSI, the filters should be changed. IMPORTANT, the incoming pressure cannot be lower than 40 PSI into the filter unit. The 0.2 micron filter (CF ) must be changed at least once every six (6) months and the 1 micron filter (MF ) at least once every three (3) months. 44 CER OPTIMA Service Manual

45 40-60 PSI must be seen at this Post Filter Gauge If not, but the pressure is correct at the # 3 gauge, check the pressure drop. Greater than 5 PSI, the filters need to be changed The pressure at Gauge 3 must be between 40 and 60 PSI for the reprocessor to function optimally. Filtered water to the reprocessor Connect to Water supply Post Filter 0.2 micron CF Pre-Filter 1 micron MF Direction of water flow Figure 20 If the pressure at gauge 1 is 5 PSI less than at gauge 3, this pressure drop indicates one of the filters is starting to become clogged and requires replacement. Remember to always read the pressure only when water is flowing. CER OPTIMA Service Manual 45

46 LOW WATER LEVEL - If the basin is FULL of water at the time of the alarm. Note, even though the basin is full, the reprocessor has detected the fill time as exceeded the maximum allowed time limits. Problem Solution Reprocessor is out of level Verify the level of the unit: See figure 21 and 22. If the machine is biased to a specific side, the water level sensor may not be able to detect the basin is full. Level sensor is not detecting correct fluid level in the basin Water filters clogged Verify the level sensor is not obstructed and is functioning correctly. See figure 23 Replace water filters. Even though the basin is filled, if the fill rate is below minimum requirements, the reprocessor will alarm for LOW WATER LEVEL. To verify if the filters are clogged, a simple check of the pressure differential is made. The pressure differential must be checked when water is flowing (Dynamic pressure). Even with clogged filters, if pressure is checked when no water is flowing (Static Pressure), the water pressure can appear to be correct, but is not. To check the pressure, simply start a cycle and observe the three pressure gauges. If the pressure differential is from the first to the last gauge is greater than 5 PSI, the filters should be changed. Remember, the incoming pressure cannot be lower than 40 PSI into the filter unit. The 0.2 micron filter (CF ) must be changed at least once every six (6) months and the 1 micron filter (MF ) at least once every three (3) months. Figure 21 Figure CER OPTIMA Service Manual

47 Overflow port. Fluid should not be going down this port at anytime if the reprocessor is operating properly. The most common cause is machine level, improper endoscope placement or unused endoscope connectors left connected in the basin. Basin level sensor. Verify the two holes in the body are not obstructed and that the cover is not tipped or out of place. Drain Screen Figure 23 Problem Solution Insufficient HLD in reservoir Verify the reservoir has a minimum of 4 gallons of HLD in the reservoir for OPTIMA CER-1 and a minimum of 5 gallons for the OPTIMA CER-2. See figure 24. Disinfectant being sprayed down the overflow port in the back left portion of the basin. Chemical inlet hose is kinked Only endoscope hookups that are attached to the endoscope should be connected to the basin connector channel ports. Any unused basin connector ports should have a right-angled basin connector inserted. See figure 23A and 23B. Fluid from the distal tip may also be sprayed into the overflow drain. Make sure the distal tip is not facing the back left corner and that it is tucked under the body of the scope. Verify the chemical inlet hose has not been kinked or squeezed if the reservoir has recently been accessed, such as refilling or cleaning purposes. If reprocessor is on a movable cart, hoses can easily become entangled and kinked. See figure 25 CER OPTIMA Service Manual 47

48 Disinfectant filter is clogged Dirty drain screen Drain covered by objects Internal Transfer pump is not functioning Bottles or containers being reprocessed in OPTIMA If the hose is removed for any reason, the correct orientation of the hose is imperative when reattaching. The hose contains a check valve in line with the disinfectant filter. If this hose is reversed, no fluid will flow. Always connect the 90 degree elbow fitting to the back of the reprocessor and the straight fitting on the hose to the reservoir. Refer to figure 26 If the drain is clogged and restricts the draining of disinfectant, this can cause a loss of disinfectant because not all may return to the reservoir prior to the end of the disinfectant cycle affecting the next cycle in the form of a LOW HLD LEVEL alarm. If the drain is covered by an object(s) that restricts the draining of disinfectant, this can cause a loss of disinfectant because not all may return to the reservoir prior to the end of the disinfectant cycle, affecting the next cycle in the form of a LOW HLD LEVEL alarm. See figure 23C Check and verify pump operation. Change disinfectant filter (possible clogged filter). Water bottles, suction bottles or any container CANNOT be reprocessed in a MEDIVATORS reprocessor. These items can retain fluid and cause either a loss of disinfectant or a gain of water in the disinfectant. Refer to the directions for proper cleaning of these items from the manufacture of the items. Refer to Figure 23D 48 CER OPTIMA Service Manual

49 Right-angled basin connectors (shown in this figure) should be inserted in any basin channel port that are not being used. NEVER leave unused endoscope hookups in the basin that are not connected to an endoscope. This practice can lead to disinfectant being sprayed down the overflow drain. Figure 23A Do not leave endoscope hook ups in the basin that are not attached to an endoscope. The spray or turbulence caused by this loose hook up can cause HLD loss. Figure 23B CER OPTIMA Service Manual 49

50 Button bags should not be placed over the drain. This can reduce the flow to the drain. Always place button bags in a location away from the drain. Keep the drain area clear. Figure 23C Figure 23D 50 CER OPTIMA Service Manual

51 Note that for the CER-1 OPTIMA the disinfectant must be AT OR ABOVE the 4 gallon mark and for the CER-2 OPTIMA the disinfectant must be AT OR ABOVE the 5 gallon mark. If using an CER-2 OPTIMA and fluid is between the 4 and 5 gallon mark, a LOW HLD LEVEL alarm will be the result. Disinfectant filter MUST be changed with every disinfectant change to prevent LOW HLD LEVEL Alarm. A clogged filter will slow the fill rate of the disinfectant into the basin. If the HLD does not fill within the specific period, it will alarm. LOW HLD LEVEL Figure 24 CER OPTIMA Service Manual 51

52 Scanner connection Chemical inlet hose. This hose has the disinfectant filter connected in line. The 90 elbow fitting attaches to the reprocessor and the straight fitting to the reservoir. If reversed, no fluid will flow. Figure 25 LOW HLD LEVEL - If basin is full of disinfectant, but still alarms Problem Reprocessor is not level Level sensor is not detecting correct fluid level in the basin Disinfectant filter is clogged Solution Verify machine is properly leveled. Refer to figures 21 & 22. Verify the level sensor is not obstructed and functioning correctly. See figure 23 The filter must be changed every time the disinfectant is changed. Failure to do so will cause the LOW HLD LEVEL alarm. A clogged filter will slow the fill rate of the disinfectant to the basin. The machine will alarm LOW HLD LEVEL after a specific time period if the basin is not filled in that specified time period. CHECK WATER FLOW Problem Solution Incoming water pressure is too low Verify water pressure is between 40 and 60 PSI. Refer to figure 20 Water filters clogged Replace water filters Drain Screen clogged Clean drain screen in basin. The unit draws water through this screen if clogged or obstructed, the reprocessor will sense as low flow. 52 CER OPTIMA Service Manual

53 CYCLE CANCELED Problem Cycle was canceled by pressing stop Lid was not closed for more than 2 minutes during the cycle Power Interruption Solution Pressing stop cancels the cycle. Do not press stop unless canceling the cycle is required. The reprocessor is constantly monitoring the lid to verify it is closed. If the lid is detected to be open for more than 2 minutes, the cycle will automatically cancel as a safety precaution. If the lid is closed, but not latched, the lid may not be detected as closed, even though it appears closed. Always latch the lid when in use to prevent this from occurring. This error can occur if a power interruption occurs during reprocessing. BASIN FULL - This error is indicating the basin is not draining when it should be. The issue relates completely to the draining of the basin Problem Drain screen clogged HLD Line return line restriction Power Interruption Pressure Sensor Failure Solution Clean the basin drain screen. Verify nothing is occluding the drain such as a button bag. See Figure 23C Verify that return line is not kinked or pinched. If recently removed verify the hose is connected correctly. This hose only allows flow in one direction. This error can occur if a power interruption occurs during reprocessing. Replace Pressure Sensor. Consult MEDIVATORS Technical Service BASIN LEVEL LOW (DURING RINSE CYCLE) - Water filled initially, but there is a loss of fluid during the cycle that has caused this alarm. Problem Solution Water supply rate to low Verify the water pressure is between PSI Water filters clogged Replace water filter(s) Internal drain valve defective Verify valve is properly sealing. During the rinse cycle, no water should be seen flowing back to the drain. If so, this is an indication the valve is not sealing properly. Remove all unused hook ups from the basin and replace with right-angled basin connectors, refer to figure 23A. CER OPTIMA Service Manual 53

54 BASIN LEVEL LOW - Disinfectant is being lost after the initial fill of the basin. Problem Disinfectant is flowing down the overflow. Disinfectant shooting down drain from endoscope Level sensor is not detecting the level of the fluid correctly Internal drain valve defective Solution Verify level of machine, see figures 21 & 22 Verify the distal tip of the endoscope is not spraying towards the overflow. Always tuck the tip of the endoscopes under the body of the endoscope. Verify operation of the level sensor. See figure 23 Verify valve is properly sealing. During the rinse cycle, no water should be seen flowing back to the drain. If so, this is an indication the valve is not sealing properly. Remove all unused hook ups from the basin and replace with right-angled basin connectors, refer to figure 23A. TEMPERATURE ERROR - This alarm indicates the disinfectant temperature is either below the minimum basin temperature called out by the program setting or above 42 C Problem Disinfectant reservoir temp too low Disinfectant reservoir temp >42 C Solution Verify reservoir temp is set correctly for the specific disinfectant and reservoir is connected to power Verify reservoir temp is set correctly and reservoir is connected to power. See figure CER OPTIMA Service Manual

55 The dial gauge is the actual temperature of the solution. If temperature is below the minimum basin temp for the selected disinfectant or above 42 C a TEMPERATURE ERROR will occur. The temperature displayed is the SET temperature, not the actual. If the display is not illuminated, the unit is not receiving power. Check the cord or fuse. Figure 26 TEMP SENSOR ERROR - This is only referring to a failure of the actual sensors Problem The temp is monitored by two separate sensors. When the temperature difference between the two probes is >3, then this alarm will occur Solution The temperature probe S4 or S5 (probes located in the drain) may be defective. Review sensor wire harness connections. In diagnostics, review the temp readings for S4 and S5. If the difference is greater than 3º, the temp probe is defective. Note: Temperature is displayed without decimal points. 350 = S4 is the temperature used for the displayed temperature. CER OPTIMA Service Manual 55

56 BASIN DRAIN TIMEOUT - Only occurs when BASIN TO DRAIN button is pressed Problem Drain screen clogged HLD line restriction Pressure sensor is defective Channel Pump is defective Solution Clean drain screen or remove any object that maybe covering the drain screen. Verify there are no kinks in HLD hose Possible defective pressure sensor Verify pump operation. Repair/Replace if necessary LOW CHAN PRESSURE - During the rinse cycle Problem Drain screen clogged Water supply is turned off Pressure sensor defective Channel pump is not pumping Solution Clean drain screen. Prevent endoscopes or other objects from covering the drain. Turn on water supply Possible defective pressure sensor Inspect Channel Pump. Verify the Chemical inlet hose is not kinked or disconnected. LOW CHAN PRESSURE - During HLD portion of cycle Problem Drain screen clogged Disinfectant reservoir empty Disinfectant supply line restriction Disinfectant filter clogged Channel pump not pumping Pressure sensor defective Solution Clean drain screen. Prevent endoscopes or other objects from covering the drain. Fill reservoir Remove restriction from line; verify the supply line is connected and that the disinfectant filter is properly connected. Replace disinfectant filter. Change after every disinfectant change. Inspect channel pump Possible defective pressure sensor NVRAM - This error can occur at any point in the cycle Problem Internal Communication fault. May occur during a power fluctuation Solution If either the FULL or HLD RINSE button is illuminated, press it to turn it off. Press the down arrow until you see HLD CYCLE CNT RESET. Press the arrow. Then press ENTER to accept the change. Reselect the FULL or HLD RINSE cycle and run a test cycle. The customer may need to power the unit up and down. 56 CER OPTIMA Service Manual

57 Error Conditions Not tied to a specific error AFTER THE COMPLETION OF ONE CYCLE, ANOTHER CYCLE IMMEDITALY STARTS Problem The CONTIUNOUS RUN function has been activated SCANNER DOES NOT READ BAR CODES Problem Scanner not activated Scanner not plugged in Solution In the SERVICE MENU this option should be set to NO. If not changed from YES to NO. Refer to the OPTIMA USER manual for details Solution Verify in the sub menu that the scanner is activated. Refer to the OPTIMA USER manual for details Verify the scanner is plugged in to the back of the reprocessor. Refer to figure 25. Scanner requires reprogramming Refer to the BARCODE SCANNER REPLACEMENT section of the repair manual. RESERVOIR GAINING VOLUME Problem Water in basin at the end of the initial rinse cycle. Fluid remaining in basin at end of cycle Obstruction in basin Bottles or containers being reprocessed in OPTIMA Unauthorized items in basin and items covering the drain Solution If using HLD Rinse and water pressure is too great. If pressure is too high, water can be carried over from the initial rinse into the disinfectant. Check machine level. If out of level, fluid cannot completely return to the drain. Clean the drain screen Water bottles, suction bottles or any container CANNOT be reprocessed in a MEDIVATORS reprocessor. These items can retain fluid and cause either a loss of disinfectant or a gain of water in the disinfectant. Refer the directions for proper cleaning of these items from the manufacture of the items. Refer to figure 23B Only endoscopes and their related accessories (buttons and caps) are to be reprocessed at the same time. The reprocessing of inappropriate items with endoscopes can, depending on the circumstance cause either gain or loss. There are a certain number of soak only devices that can be reprocessed, but must be reprocessed independently of endoscopes and adhering to the guidelines outlined in the document SOAK ONLY DEVICES MAY BE REPROCESSED IN MEDIVATORS AER S. Bulletin number found at CER OPTIMA Service Manual 57

58 RESERVOIR LOSING VOLUME Problem Reservoir level dropping over time Loss of up to 1 gallon per cycle Constant loss Disinfectant being sprayed down the drain. Dirty Drain screen Drain covered by objects Bottles or containers being reprocessed in OPTIMA Solution There is a typical loss of disinfectant up to 20 ml per endoscope per cycle. If the loss is at a low rate, it may simply be normal loss. Verify the distal tip of the endoscope is tucked under the body of the endoscope preventing the fluid from shooting towards the overflow drain Verify the level of the machine. If out of level the fluid will go down the overflow drain. Only hook ups that are attached to the endoscope should be connected to the basin channel ports. Any unused basin connector ports should have a rightangled basin connector inserted. See figure 23A & 23B. A clogged drain screen will prevent the proper return of HLD in the prior cycle. This loss will affect this next cycle in the form of a LOW HLD LEVEL alarm. If the drain is covered by an object(s) that restrict the draining of fluid, this can cause a loss of disinfectant because not all may return to the reservoir in the prior cycle, affecting the next cycle in the form of a LOW HLD LEVEL alarm. See figure 23C Water bottles, suction bottles or any container CANNOT be reprocessed in a MEDIVATORS reprocessor. These items can retain fluid and cause either a loss of disinfectant or a gain of water in the disinfectant. Refer the directions for proper cleaning of these items from the manufacture of the items. Refer to figure 23D 58 CER OPTIMA Service Manual

59 FLUID LEAKING FROM MACHINE Problem Fluid found behind machine and over the back side of the machine Fluid found around the unit Fluid leaking from hoses Solution Moisture will build up on the bottom side of the reprocessor lid. When the lid is lifted up, condensation can flow down the lid and down the back of the machine if the lid is not fully opened. Always open the lid to the full, upright position quickly. If endoscope hook ups are allowed to drape over the side of the machine, fluid may flow out of these connections, especially if still connected to the basin connectors. Many times, simply disconnecting the hose and wiping the O-ring on the connector and reconnecting can rectify the situation. Recovering from a Power Outage If a power outage should occur during a reprocessing cycle, the cycle must be aborted and a new reprocessing cycle must be performed. After the power outage, the operator must determine where in the cycle the outage occurred. If the basin contains disinfectant, the fluid must be manually drained back to the reservoir using the BASIN to RSVR manual function. If the outage is for a prolonged period, verify the disinfectant is at the proper temperature prior to stating the new cycle. If the basin contains rinse water, the fluid must be manually pumped to the drain using the manual function BASIN to DRAIN. Refer to the OPTIMA USER manual for details on how to operate the manual functions. CER OPTIMA Service Manual 59
