CLEANING DISCHARGE HONEYCOMB
Discharge air honeycomb should be cleaned
every six months. Dirty honeycomb will
cause merchandisers to perform poorly.
The honeycomb may be cleaned with a vacu-
um cleaner. Soap and water may be used if
all water is removed from the honeycomb cells
before replacing. Be careful not to damage the
honeycomb.
1. Using a flat object such as a screw driver,
behind the rear edge of the honeycomb on
on the right hand end, and gently pull
down.
2. Clean with a mild detergent and warm
water and dry the honeycomb.
3. After cleaning, replace in reverse order.
Damaged honeycomb must be replaced.
CLEANING COILS
Condenser coils should be cleaned at least
once per month. Additional cleaning may be
needed depending on the operational environ-
ment. A dirty condenser blocks normal airflow
through the coils.
Airflow blockage increases energy consump-
tion and reduces the merchandiser’s ability to
maintain operating temperature.
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris. Do not bend
coil fins. Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles.

•
Do not introduce water faster than waste outlet can drain
•
NEVER INTRODUCE WATER ON SELF CONTAINED
UNIT WITH AN EVAPORATION PAN
