Preventive 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
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 bleach.
4. Clean and disinfect drain lines and evaporator pan with a solution of warm water
and bleach.
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.

NOTE: DO NOT USE SHARP UTENSILS.
