Maintenance
Randell strongly suggests a preventive maintenance program which would include the
following Monthly procedures:
1. Cleaning of all condenser coils. Condenser coils are a critical component in the life
of the compressor and must remain clean to assure proper air ow and heat transfer.
Failure to maintain this heat transfer will affect unit performance and eventually destroy
the compressor. Clean the condenser coils with coil cleaner and/or a vacuum, cleaner
and brush. Use of any lter over the condenser coil may result in poor performance
of the equipment. The factory does not recommend any auxiliary lter be used on
the condenser coil. Any failures of the unit as a result of an auxiliary lter will not be
covered under warranty.
2. Clean fan blade on the condensing unit and evaporator assembly.
3. Clean and disinfect drain, drain lines and evaporator pan with a solution of warm water
and mild detergent.
4. Clean all gaskets on a weekly if not daily basis with a solution of warm water and a mild
detergent to extend gasket life.
5. Lubricate door hinges with lithium grease.
6. Clean drawer tracks of any debris.
7.The drawer module may be removed from the cabinet for cleaning by loosening the two
¾” round screws on rear anchor bracket. Once loosened the drawer cartridge may be
removed from the cabinet to clean the interior of the cabinet. Clean with mild soap and
warm water mixture. Re-install the drawer cartridge by properly aligning the cartridge
to the bracket and tightening the ¾” round screws.
8. Inspect all silicone seams at interior of the base cabinet on a monthly basis. Re-apply
food grade silicone sealant as needed to any seams where silicone has peeled away
or cracked. Apply silicone to a clean dry surface. Allow sufcient drying time to assure
best adhesion of sealant.
