Model 4000-LC series GENERAL MAINTENANCE
Unit must be turned OFF & Unplugged during any and all maintenance/ service
.
Hazards!
Periodic Cleaning
Beginning with the initial installation, the interior surfaces of the cabinet should be
periodically wiped down with a solution of warm water and laboratory detergent.
This solution will remove any odors from spillage that has occurred. The detergent
should be removed using distilled water followed by a wipe down with isopropyl
alcohol. The exterior of the cabinet should also be cleaned frequently with a
laboratory detergent solution followed with a distilled water rinse.
All surfaces (Internal and/or external) can be cleaned using isopropyl alcohol.
NOTE:
All moving parts have been permanently lubricated and will generally require no
maintenance.
Cleaning the condenser (Air cooled only – Models 4002-LC & 4005-LC)
For air cooled units, 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.

Remove condenser cover grill (Total 16 screws)
b.
Using a wire brush or a brush with stiff bristles can be used to 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.
