Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range. b Interference may occur in the vicinity of equipment marked with the following symbol: NOTE: 1. At 80 MHz and 800 MHz, the higher frequency range applies. 2. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the warmer is used exceeds the applicable RF compliance level above, the warmer should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the warmer. b. Over the frequency range 150 khz to 80 MHz, field strengths should be less than [VI] V/m.

Cleaning and Preventative Maintenance WARNING To prevent serious personal injury, death, or property damage: Do not steam clean, hose down or flood the interior or exterior with water or liquid solution of any kind. Do not use water jet to clean. Failure to observe this precaution will void the warranty. (IPX-0 - Listed as Ordinary) CAUTION Fire hazard. NO SCRAPERS Do not use flammable cleaning agents on the appliance. NO WIRE BRUSHES NO STEEL PADS NOTICE: To protect surfaces, never use abrasive cleaning compounds, chloride based cleaners, or cleaners containing quaternary salts. Never use hydrochloric acid (muriatic acid) on stainless steel. Never use wire brushes, metal scouring pads or scrapers. Failure to observe this precaution will void the warranty. Protecting Stainless Steel It is important to guard against corrosion in the care of stainless steel surfaces. Harsh, corrosive, or inappropriate chemicals can completely destroy the protective surface layer of stainless steel, epoxy or plastic. Abrasive pads, steel wool, or metal implements abrade surfaces causing damage to this protective coating and eventually result in areas of corrosion. Water can contain high to moderate concentrations of chloride, causing oxidation and pitting that results in rust and corrosion. In addition, acidic spills that remain on metal surfaces are contributing factors in corroded surfaces. Proper cleaning agents, materials, and methods are vital to maintaining the appearance and life of this warmer. Spilled items should be removed and the area wiped as soon as possible but at the very least, a minimum of once per day. Always wipe standing water as quickly as possible. WARNING Electric shock hazard. Perform lockout/tagout procedures before cleaning or servicing this appliance. NOTICE: Always follow appropriate state or local health (hygiene) regulations regarding all applicable cleaning and sanitation requirements. Cleaning Agents Always use the proper cleaning agent at the manufacturer s recommended strength. Contact a local cleaning supplier for product recommendations. Cleaning Materials Cleaning can usually be accomplished with the proper cleaning agent and a soft, clean cloth. When more aggressive methods are needed, use a non-abrasive scouring pad on difficult areas and make certain to scrub with the visible grain of the surface metal to avoid surface scratches. How to Clean the Warmer 1. Disconnect the warmer from the power source. 2. Remove and wash any detachable items such as the support assembly with hot, soapy water. Dry with a clean, lint-free cloth. 3. Clean the interior and exterior of the warmer with a mild soap and water solution. Apply the solution with a clean, damp cloth. Do not use commercial or household cleaners that contain ammonia. NOTE: Make sure to wipe the control panel, door vents, door handle or door button, and door gaskets. 4. Remove all detergent residue from the interior and exterior of the warmer with a clean, damp cloth. 5. Dry the interior and exterior of the warmer with a clean, lint-free cloth. Leave the door open until the interior is completely dry. 6. Sanitize the interior of the warmer with a sanitizing solution. This solution must be approved for use on stainless steel surfaces. 7. Clean the warmer glass with glass cleaner or distilled vinegar. 8. Replace the support assembly. 14 MN-39217 Rev 3 12/18 DC Series Fluid Warmer

Vacuum the dust from the fan vents at the back of the appliance. Clean the interior. Make sure the controller LEDs illuminate.* Make sure the interior LED illuminates (if applicable).* Make sure the fluid insert assemblies are installed. Inspect the fluid insert assembly for damage or missing pieces*. Make sure the baskets move smoothly and freely. Monthly Checklist: Inspect the door gasket for tears, wear, and fit. Make sure that the seal is tight to the body. Replace the gasket if the integrity is compromised.* Inspect the air temperature sensor mounted in the interior of chamber. Ensure that the sensor guard is in place and fully secured to the warmer. Inspect the casters or feet for damage. Ensure that the components are secure and tightly threaded. Inspect the controller panel overlay for any tears or excessive wear on the graphic. Confirm that the controller works properly when the buttons are pushed.* Six-month Checklist: Verify that the chamber air temperature and the set-point temperature are comparable to the actual temperature displayed. Use a quality thermocouple placed 1" (25mm) from the sensor inside the chamber. Do not allow the thermocouple to touch any surface. Monitor the temperature for one hour in an empty interior. Note: Fluid chamber temperature may fluctuate from the set-point. The set-point will be within +0/-1.10 C (+0/-2ºF) for injection fluids and within +0/-1.67 C (+0/-3ºF) for irrigation fluids. *Contact service for immediate repair.

Service How to Replace the Fuse WARNING For protection against fire and electrical shock use only UL listed 10A, 250V fast acting fuses, 5mm x 20mm (F1, F2). Access should be made by qualified service technicians only. A hospital grade cord must be used. Refer to the owner s manual or contact the manufacturer for acceptable cords. The warmer must be connected to an equivalent receptacle marked hospital grade. FU-34955 F1 fuse 4 FU-34955 F2 fuse 3 2 1 1. Unplug the power cord from the wall outlet and the power inlet 1 on the warmer. 2. Locate the fuse compartment 2 directly below the power inlet. 3. Use a fingernail or thin implement to open the fuse compartment door 3. 4. Pull the fuse drawer 4 out of the fuse compartment. 5. Use a thin implement to push the fuses up and out of the fuse drawer 4. 6. Replace the fuse with a new fuse. 7. Push the fuse drawer 4 back into the fuse compartment. 8. Close the fuse compartment door 3. How to Manually Reset the Warmer 1. Disconnect the electrical power source to the fluid warmer. 2. Allow the fluid warmer to cool. 3. Remove three (3) screws from the top cover (on the upper edge of the back of the fluid warmer). 4. Slide the top panel toward the back of the fluid warmer and then lift to remove. 5. Locate the two (2) manual reset buttons in the middle of the bonnet. 6. Use a pen, screwdriver or other long, thin implement to firmly push the reset button(s). The button clicks when it resets. 7. Place the cover on top of the warmer ensuring that the slots on the underside of the cover line up with the bolts on the top of the warmer. Slide the cover toward the front of the warmer to lock into place. 8. Replace the three (3) screws at the back of the warmer. If the reset button trips again while the warmer is operating, contact a qualified service technician. 3 4 7 5 Part numbers and drawings are subject to change without notice. 20 MN-39217 Rev 3 12/18 DC Series Fluid Warmer
