Randell has attempted to preset the cold control to ensure that your unit runs at an opti-
mum temperature, but due to varying ambient conditions, including elevation, food prod-
uct as well as type of operation you may need to alter this temperature. Additional adjust-
ments can be made (within limits) by turning the control dial up or down until the desired
temperature is reached. Control dial is located next to the compressor (See figure A).
1. Unit Cleaning may be performed at this time.
2. Turn on unit.
3. Allow 45 minutes to one hour for your unit to cool down before loading product.
4. Load the product and proceed with food preparation.
1. Remove product from unit at the end of the day’s preparation.
2. Turn off unit.
3. Unit cleaning maybe performed at this time if the frost has melted off the surface.
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 fan blade on the condensing.
3. Clean and disinfect drains with a solution of warm water and bleach.
NOTE: DO NOT USE SHARP UTENSILS

Do not use steel pads, wire brushes, scrapers or chloride cleaners to clean
your stainless steel.
