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. The water seal is facory installed. Do not tighten the
water seal where it connects to the drain fitting. Twisting
the water seal "trap" can cause a water leak in the case's
bottom liner. Do not use thread sealant between ABS drain
fitting and water seal.
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 the
manufacturer’s instructions.
Access Panels
All electrical and drain access panels are clearly labeled on
the deck of the produce stand. The access for condensing
units (in the self contained units) is located on the side of
the stand, at the end. Ends of stand are fitted for removal,
if condensing unit has to be taken out.
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 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 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.
Hose Reel
If an optional hose reel is ordered, it will be installed at the
factory. The water supply valve is located next to the access
panel. Connect the water supply to the valve.
THE DRAIN AND WATER SEAL ARE FACTORY
INSTALLED. DO NOT USE THREAD SEALANT OR
OVERTIGHTEN THESE PARTS. DO NOT TWIST
WATER SEAL. DAMAGE TO THE DRAIN FITTING
OR WA T E R SEAL MAY OCCUR
