PREVENTATIVE 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 flow 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
(available at your local appliance parts center) and/or a vacuum cleaner and brush.
Note: Brush coil in direction of fins, normally vertically as to not damage or restrict air flow from passing
through condenser.
2. Clean all fan blades, both on the condensing unit and the evaporator assembly.
3. Lubricate door hinges with a 3 in 1 oil.
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. Stainless steel surfaces should be wiped with a damp cloth with a mild cleaning solution. DO NOT FLUSH
UNIT (ESPECIALLY THE MACHINE COMPARTMENT) WITH RUNNING WATER.
6. Sanitize food probes after EACH use.
