ULC/ULCI GENERAL MAINTENANCE
Unit must be turned OFF & Unplugged during any and all maintenance/ service
.
Hazards!
Periodic Cleaning
Beginning with the initial installation, the exterior surfaces of the ULC/ULCi should be
periodically wiped down using isopropyl alcohol or commercial grade glass cleaner.
All surfaces (Internal and/or external) can be cleaned using isopropyl alcohol. Cleaners
containing acetone can damage and remove the paint and powder coat finish on the
exterior of the cabinet and should be avoided.
NOTE:
All moving parts have been permanently lubricated and will generally require no
maintenance.
Cleaning the condenser (Air cooled only)
Monthly cleaning of the condenser will aid the heat transfer characteristics of the
refrigeration system and increase its efficiency. Dust, dirt, and lint will tend to accumulate
on the fins of the condensing unit. This obstruction will affect the flow of air through the
condenser, thereby lowering the efficiency of the system.
a.
The condenser is located on the outside end of each refrigeration section.
b.
Using a brush with stiff bristles, loosen these particles that are attached to the fins
so that they may be removed with a vacuum cleaner. Failure to keep the condenser coil
clean and free of obstructions could result in temperature loss and damage to the
compressor.
Water cooled condenser manually test or flushing the valve;
(Water cooled condenser only)
The water-cooled condenser water regulating valve should be inspected every six (6)
months. This is a visual and operational inspection, complete the following steps:
1. Turn off power to the freezer.
