CHECKING CONDENSER COIL FOR
RESTRICTIONS
NOTE: Air circulation through condenser coil,
required to cool coil, is drawn in through air in-
take grille on unit front panel and is exhausted
out through grilles on sides and back of unit.
Restricting air circulation through unit will de-
crease its cooling efficiency.
Area in front, sides, and back of unit must be kept
free of obstructions at all times which would prevent
air flow in and out of unit. Cooling unit condenser coil
should be periodically cleaned to maintain cooling
efficiency as instructed.
CHECKING ICE WATER BATH
A ‘‘gurgle’’ heard from unit indicates water level in
evaporator tank is low and more water should be
added for maximum product cooling as instructed.
