Preventive Maintenance
Randell strongly suggests a preventive maintenance program which would include
the following Monthly procedures:
4. 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 and/or a vacuum, cleaner and brush.
NOTE: Brush coil in direction of fins, normally vertically as to not damage or
restrict air from passing through condenser.
2. Clean fan blade on the condensing unit.
3. Clean and disinfect drains with a solution of warm water and mild soap.
4. Clean and disinfect drain lines and evaporator pan with a solution of warm water
and mild soap. Disconnect each end of the drain line and run the solution through
it. Do not allow the bleach water to be put into the condensate pan in the
compressor compartment.
5. Clean all gaskets on a weekly if not daily basis with a solution of warm water
and a mild detergent to extend gasket life.
6. Remove stainless steel air baffle panels in the front and rear of the prep rail.
Once the panels are removed the condensate drain troughs below the coils may
be cleaned of any debris that could have accumulated. Caution: Fins of coils are
sharp. Note: This is recommended to be performed by a service agent to any
potential damage to the finned coils
7. Inspect all silicone seams at interior of the rail and refrigerated base cabinet. Re-
apply food grade silicone sealant as needed to any seams where silicone has
peeled away or cracked
NOTE: DO NOT USE SHARP UTENSILS.
NOTE: Do not pressure wash equipment as damage to electrical
components may result.
