GENERAL MAINTENANCE
The unit must be turned off and unplugged during any and all maintenance/service to avoid the following hazards:
Extreme Cold Temp
Electrica Hazard
Hot Touch
Hand Injury
Sharp Object
Periodic Cleaning
Beginning with the initial installation, the exterior surfaces of the ULC should be periodically wiped down using isopropyl
alcohol or commercial-grade glass cleaner. Please refer to the site standard operating procedures (SOPs) for further periodic
cleaning instructions.
All surfaces (internal and external) should 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 require no maintenance.
Cleaning the Air-Cooled Condenser
It is recommended that the condenser located on the outside end of each refrigeration section be cleaned monthly. Regular
cleanings will aid the heat transfer characteristics of the refrigeration system and increase its efficiency. Dust, dirt, and lint tend
to accumulate on the fins of the condensing unit, obstructing the flow of air through the condenser and lowering the efficiency
of the system. Use a brush with stiff bristles to loosen particles that are attached to the fins, then remove them with a vacuum
cleaner.
Note: Failure to keep the condenser coil clean and free of obstructions could result in temperature loss and damage to the
compressor.
