WASTE OUTLET AND P-TRAP
The waste outlet is located in the center, 8" from the front
of the case.
A 7/8" P-trap and threaded adapter are supplied with each
fixture. The P-trap must be installed to prevent air leakage
and insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow Hussmann’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se-
riously interfere with the operation of this refrigerator,
and result in costly maintenance and product losses. Please
follow the recommendations listed below when installing
condensate drains to insure a proper installation:
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumb-
ing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section. Never use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.
3. Always provide as much down hill slope (“fall”) as
possible; 1/8" per foot is the preferred minimum.
PVC pipe, when used, must be supported to main-
tain the 1/8" pitch and to prevent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to provide the “fall” necessary for
good drainage.
5. Provide a suitable air break between the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.
6. Prevent condensate drains from freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstrong’s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a
refrigerator and a wall), provide means to prevent
freezing. The water seal should be insulated to
prevent condensation.
RED (SELF CONTAINED)
The waste outlet and P-trap are the same as the remote
except the case condensate drains to a pump assembly
mounted to the top of the case into the top of the water
evap assembly. Hot air from the condenser is forced
through the water evap assembly, evaporating the water.
Any overflow from the water evap assembly is directed
back to the pump assembly. It is critical that the case
be level to keep the water evap assembly from
overflowing!! The metal cover over the top of the con-
densing unit must be in place to force the hot condenser
air through the water evap assembly.
The condensate pump can be accessed through the front
of the closeoff panel.
