WASTE OUTLET AND WATER SEAL
The waste outlet is located in front of the fan
plenum 6 ft (1829 mm) from the left-hand end of
8 ft (2438 mm) and 12 ft (3658 mm) merchandis-
ers (facing case front). The waste outlet is located
in the center of 4 ft (1219 mm) and 6 ft (1829 mm)
merchandisers. A water seal is supplied with each
fixture. The water seal must be installed to the
waste outlet to prevent air leakage and insect
entrance into the fixture.
NOTE:
Water seal outlet must clear front skid rail.
A
tee,
adapter, plug and street ell are also supplied
with each merchandiser.
INSTALLING DRIP PIPING
Poorly or improperly installed drip pipes can
seriously interfere with the merchandiser’s opera-
tion and result in costly maintenance and product
losses. Please follow the recommendations listed
below when installing drip piping to ensure good
drainage.
1. Never use drip piping smaller than the nominal
diameter of the pipe or water seal supplied
with the merchandiser.
2. When connecting drip piping, the
water seal
must be used as part of the drip piping to
prevent air leakage or insect entrance. Never
use two water seals in series in any one
drip pipe.
D
OUBLE WATER SEALS IN SERIES
WILL CAUSE AN AIR LOCK AND PREVENT
DRAINING
.
3. Pitch the drip piping in the direction of flow.
There should be a minimum pitch of
1
/
8
in. per
foot (4 mm per 305 mm).
4. Avoid long runs of drip piping. Long runs
make it impossible to provide the pitch
necessary for good drainage.
5. Provide a suitable air break between flood rim
of the floor drain and outlet of drip pipe.
6. Prevent drip pipes from freezing:
A. Do NOT install drip pipes in contact with
uninsulated suction lines. Suction lines should
be insulated with a nonabsorbent insulation
material.
B. Where drip pipes are located in dead air
spaces, such as between merchandisers or
between a merchandiser and a store wall,
provide means to prevent freezing.
Splashguard brackets MUST be installed
before piping case.
