Once the Degas cycle is complete the CENTI is ready for normal operations. 1.4.2 Degassing Information Dissolved gases (most often air) can reduce the effectiveness of the ultrasonic action and the capabilities of the detergent to remove support material of printed parts. During normal use, the detergents will naturally degas over time, but utilizing a Degas cycle will speed up that process and return the CENTI to optimum efficiency. 1.5 Overview of Ultrasonic Modes NOTE Detergents that have not been in use for 24 hours or longer will have reabsorbed some gases. In this situation, ALWAYS run a Degas cycle prior to support removal operations. There are three Ultrasonic Modes of operation. These are identified below: 1. Timed Sonics When operating in Timed Sonics Mode, a timer counts down the remaining time that sonics will run in the cycle. For Information about operating in Timed Sonics Mode see Section 1.5.1 Timed Sonics Mode. 2. Constant Sonics In Constant Sonics Mode, the ultrasonics will continue until the SONICS cutton is pressed or power is turned off to the CENTI. For Information about operating in Constant Sonics Mode see Section 1.5.2 Constant Sonics Mode. 3. Auto Sonics In Auto Sonics Mode the sonics begin as soon as the set temperature is attained and will continue until the cycle timer reaches 0 minutes. For Information about operating in Auto Sonics Mode see Section 1.5.3 Auto Sonics Mode. In any of the above Sonics Modes the ultrasonics can be stopped at any time by pressing the SONICS button.

2. GENERAL CARE AND MAINTENANCE 2.2.2 Draining the Tank Prior to draining the CENTI the unit should be powered off and the plug should be removed from the cord receptacle as shown in Figure 7. Power Cord Receptacle. Make sure the drain tube is placed into a proper storage receptacle for the used detergent. Open the drain valve by turning it counter-clockwise 90 degrees until the valve is parallel to the valve body. The unit will now drain. Properly dispose of all detergents according to local disposal guidelines. 2.3 Cleaning the Tank First, drain the tank following the steps outlined in Section 2.2.2 - Draining the Tank. Anytime the CENTI tank is emptied, operators should do a close visual inspection of the tank to remove any contaminants or debris. To avoid scratching or damaging the tank use water and a non-abrasive cloth to wipe down the interior of the unit. It is recommended to check any baskets or trays that are being used during the support removal process to ensure they are free from contaminants also. Any baskets or other equipment can be cleaned using water and a soft cloth. CAUTION Never immerse the CENTI in water as the electronics will be damaged. ALWAYS turn the unit off prior to cleaning, filling or draining and be sure to remove the plug from the receptacle and from the power source. 2.4 Maintaining Detergent Levels It is important for the CENTI to always have the proper amount of detergent in the tank to ensure safe and efficient operation. There is a fluid level indicator on the inside of the tank. See Figure 8. Fluid Level Indicator When removing parts from the CENTI use care to limit the amount of detergent lost during the removal. Figure 8. Fluid Level Indicator When heavy or bulky parts are removed from the tank excessive detergent may be lost. Always monitor detergent levels and refill the tank as needed. Keep in mind that when large amounts of detergent are added to the tank, a Degas cycle may be necessary. See Section 1.4.1. Degas Procedures PostProcess Technologies, Inc. www.postprocess.com REV C page 14
2. GENERAL CARE AND MAINTENANCE 2.5 Exceeding Tank Capacity Care should always be used to avoid exceeding the CENTI tank capacity or overloading the unit. Always use a tray or basket to hold the parts being cleaned. Allow at least one inch (1 ) of space between the bottom of the tank and the tray allowing for adequate cavitation. Remove the tray from the detergent carefully to avoid spilling excess detergent. 2.6 Covering the Tank CAUTION If a part is resting on the bottom of the tank it will not be cleaned properly and the CENTI could be damaged. The picture to the left depicts the CENTI with the cover on the tank. Using the cover allows the tank to reach the desired temperature more quickly. The cover reduces the amount of detergent that is lost due to evaporation. The red callout in the picture is illustrating the cover vents. CAUTION AVOID obstructing the cover vents as it may cause the CENTI to overheat. Never place any weight on the cover as it may become damaged or misshapen. Avoid storing any objects on or above the CENTI as falling objects will damage the cover and may damage the CENTI. 3.
