CLEANING EVAPORATION PAN

The condensate water outlet for self

condensate evaporation pan will reduce the
pan's evaporation capacity. The evaporation
pan waste water will overflow and spill onto the
floor if the pan capacity is reduced.
Unplug merchandiser before servicing. Always
wear gloves and protective eye wear when cleaning
evaporation pan. Remove accumulated debris
from the evaporation pan. Be sure to remove
any dirt, debris or liquids from the pan.
Evaporation Pan is Hot!
and poses risk of bodily injury
and protective eye wear when servicing. Turn off
evaporation pan heater, and allow pan to cool.
