Plumbing; Waste Outlet And P-Trap; Installing Condensate Drain - Hussmann DSF Installation & Operation Manual

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. The water seal is facory installed. Do not tighten the
water seal where it connects to the drain fi tting. Twisting
the water seal "trap" can cause a water leak in the case's
bottom liner. Do not use thread sealant between ABS drain
fi tting and water seal.
A 1-1/2" P-TRAP and threaded adapter are supplied with
each fi xture. The P-TRAP 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

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 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 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.
