Plumbing
Waste Outlet and P-TRAP
The waste outlet is located off the center of the case on
one side allowing drip piping to be run lengthwise under
the
fi xture. There are 3 drains in each fi xture that can be
easily located.
1-1/2", 1" and 3/4" P-TRAPS and threaded adapters
are supplied with each
fi xture. The 3 P-TRAPS must be
installed to prevent air leakage and insect entrance into
the fi xture.
NOTE: PVC-DWV solvent cement is recommended. Follow the
manufacturer’s instructions.
Installing Condensate Drain
Poorly or improperly installed condensate drains can
seriously 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
plumbing system
fl oor 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
maintain the 1/8" pitch and to prevent wrapping.
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 fl ood rim of
the fl oor 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 non absorbent insulation
material such as Armstrong's Armafl ex.
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.
