Plumbing
Waste Outlet and P-TRAP
The waste outlet is located in front and center of the case
on both sides which allows for suitable access to each drain
allowing drip piping to be run lengthwise under the fixture. A
1-1/2” 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
seriously restrict 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
plumbing 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 pos
-
sible; 1/8” per foot is the preferred minimum. PVC pipe,
when used, must be supported to maintain 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 mate-
rial such as Armstrong’s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a refrig-
erator and a wall), provide means to prevent freez
-
ing. The water seal should be insulated to prevent
condensation.
