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
fixture. There are 3 drains in each fixture that can be easily
located.
1-1/2", 1" and 3/4" P-TRAPS and threaded adapters are
supplied with each fixture. The 3 P-TRAPS must be installed
to prevent air leakage and insect entrance into the fixture.
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 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 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 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 non absorbent 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.
