cleaners and cloths could scratch finish of unit, marring its
appearance and making it susceptible to soil accumulation.
Do not use harsh chemicals such as bleach, cleaners
containing bleach, or oven cleaners to clean this unit.
Daily Cleaning
1. Move the Power I/O (on/off) Switch to the O (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 over-
flowing.
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 well with a clean, sanitized cloth to remove
the detergent residue. Repeat until all detergent residue is
gone and the well is clean.
5. Wipe dry the entire unit using a non-abrasive, dry cloth.
6. Wipe down the outside of the louvered or grill-style panels
installed in the ventilation openings.
Monthly Cleaning
A refrigeration technician must perform the following procedure
monthly to maintain proper and efficient operation of refrigerated
units 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. Remove the duct from the duct collar.
3. Remove the duct bracket for access to the condenser coil
cooling fins.
a. Remove the two screws and tilt the duct bracket out of
the groove.

4. 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.
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.
