ROUTINE MAINTENANCE
Air Filter Cleaning
The air filter must be cleaned monthly to ensure proper operation of the dispenser. A dirty air filter will reduce
the refrigeration capacity and can potentially damage the compressor. To remove the filter, open the front
merchandiser and locate the pull handle protruding from the front panel. It is located above the LCD display.
Pull the air filter straight out to remove. Clean it with a mild dish washing soap and water solution and dry
thoroughly before reinstalling. A degreaser may be required if the filter is greasy.
NOTE : If the dispenser is located in a particularly dusty area or with airborne grease such as the cooking area
of a fast food restaurant then the filter should be cleaned every two weeks.
Rear Seal Replacement
The rear seals must be replaced annually. Failure to do so can result in rear seal leaks and potential
establishment flooding. The rear seal can be replaced from the front of the dispenser. The barrel must be
drained and the faceplate removed to access the seal. The process below describes the procedure for one
barrel. Repeat for all barrels.

1 On the home screen press the up or down arrow until the barrel to be sanitized is
highlighted. Press the green button and then select OFF. Press the green button again and
select DEFROST.
2 After the defrost cycle is complete, navigate to the MAINTENANCE menu and start the DRAIN
BARREL process. Follow the prompts until the barrel is empty and then end the process.
3 Vent the barrel of all pressure.
4 Remove the faceplate and beater bar. Be sure to catch the reaming liquid from the barrel
when removing the faceplate.
5 With a small pick or corkscrew type seal puller, reach into the back of the barrel and remove
the rear seal. See illustration below.
6 Lubricate the inner diameter on the new seal with Dow Corning 111 NSF approved
lubricant.
• DO NOT lubricate the outer diameter of the seal.
• DO NOT use a hydrocarbon based lubricant as swelling and premature seal failure will
occur.
7 Reinstall the seal with the “V” groove facing the product chamber. Ensure the rear seal is
firmly seated by checking to make sure it is flush with the back of the barrel.
8 Reinstall the beater bar and faceplate.
9 Return to the MAINTENANCE menu and start the GAS PURGE process followed by the FILL
BARREL process.
