CLEANING CONDENSER COIL (SEE FIGURE 23)
UNIT WITH AIR-COOLED REFRIGERATION SYSTEM
NOTE: Circulating air, required to cool the refrigeration system condenser coil, is drawn in through
louvers on front and exhausted out through louvers on sides and back of Unit. Restricting air
circulation through Unit will decrease its cooling efficiency.
Periodically clean condenser coil as follows:
1. Press ‘‘OFF 1’’ and ‘‘OFF 2’’ switches on Unit control panel to stop refrigeration system and beaters
motors.
2. Remove condenser coil access panel and condenser coil air filter.
3. Clean condenser coil and condenser coil air filter with vacuum cleaner, low pressure compressed air, or a
soft brush.
4. Install condenser coil air filter and condenser coil access panel by reversing removal procedure.
5. Press ‘‘AUTO 1’’ and ‘‘AUTO 2’’ switches on Unit control panel to start refrigeration system and beaters
motors.
UNIT WITH WATER-COOLED REFRIGERATION SYSTEM
The high-pressure cutout switch, located inside the lower control box (see Figure 24), will shut the Unit
refrigeration system down when overheated (high head pressure) caused by lack of cooling water. After problem
has been corrected and the head pressure has decreased, the reset button on the high-pressure cutout switch
must be pressed to restart the refrigeration system.
CLEANING AND SANITIZING
DAILY CLEANING OF UNIT
Daily, or more often if necessary, wash all external surfaces of the Unit with a mild soap solution. Rinse with

applicable system switches. Proceed as follows:
1. Press SIDE 2 ‘‘OFF’’ switch to stop beater motor and refrigeration in No. 2 freeze cylinder, which is not to
be defrosted. ‘‘OFF 2’’ fault message will appear on message display.
2. Press ‘‘MANUAL DEFROST’’ switch to start defrost cycle on No. 1 freeze cylinder. ‘‘DEFROST 1’’
message will appear on message display as long as defrost cycle is in progress.
