Randell 2010FMJB Owner's Manual - Preventive Maintenance

Unit Operation

Randell has attempted to preset the cold control for an average interior temperature of

38°F at the factory but due to varying ambient conditions, including elevation, food product

as well as type of operation you may need to alter this temperature. Additional adjustments

can be made (within limits) by turning the control dial up or down until the desired tempera-

ture is reached. The control dial is located on the evaporator housing inside the base.

Your reach-in will maintain proper temperatures when utilized properly. It is strongly recom-

mended that the doors be kept closed as much as possible. This is especially important in

the summer and in kitchens exceeding 80° F.. Do not leave the covers open for prolonged

periods of time. Make sure doors close properly after each use.

Note: Even though your reach-in was designed for heavy use, excessive door open-

ings should be avoided, in order to maintain proper box temperature and

eliminate the possibility of coil freeze up.

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 flow from passing through condenser.

2. Clean all fan blades, both on the condensing unit and the evaporator assembly.

3. Lubricate door hinges with lithium grease.

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
