1. Move the Power On/Off Switch to the “Off” position and

allow the unit to defrost.

NOTE: If a catch pan is used underneath the drain fitting, make

sure the pan is emptied regularly to prevent over­flowing.

2. Remove and wash any pans and adapters.

3. Clean the well using a clean cloth or sponge and mild

detergent. Use a plastic scouring pad to remove any
hardened food particles or mineral deposits.

4. Wipe down the wells with a clean, sanitized cloth to remove

the detergent residue. Repeat until all detergent residue is
gone and the well is clean.

5. Wipe down the outside of the louvered or grill-style panels

installed in the ventilation openings.

Monthly Cleaning

Perform the following procedure monthly to maintain proper and
efficient operation of the Refrigerated Drop-In Wells as well as
prevent malfunction.

1. Remove and clean both sides of the louvered or grill-style
panels that are installed in the ventilation openings. Dirt
and dust build-up in the panels can restrict air flow to the
condensing unit and cause over-heating.

2. Clean the condenser coil cooling fins. Dirt, dust, and lint
build-up in the cooling fins will prevent proper cooling of
the refrigerant in the refrigeration system. This buildup will
cause inefficient operation and can lead to unit failure. Use
the following methods to clean the condenser coil cooling
fins:

• Vacuum the cooling fins.

• Brush the cooling fins vertically using a condenser coil

brush. NOTICE: Use caution when brushing the

cooling fins, they are delicate and can be bent
easily. DO NOT use a wire brush.

Figure 11. Condenser Coil Cooling Fins

NOTE: Depending on the conditions of the installation site, this

cleaning procedure may need to be performed more
often or less often than monthly. Monitor the level of
dirt, dust, and lint buildup on the panels and cooling
fins, and make adjustments to the frequency of
cleanings as necessary.
