Unit Operation
Your display merchandiser's temperature is adjusted by a cold control which for the 40026
is located on top of the unit and on the 4030GA is located directly behind the louvered
panel on the access side of the merchandiser. It is important to keep the doors closed as
much as possible. This is especially important in the summer and when ambient
temperatures exceed 80
°
F. to help reduce the chance of condensation forming on the glass
and to increase the efficiency of the merchandiser.
Note: Even though your display case was designed for heavy use, excessive door openings
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 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
