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 the merchandiser (facing case front). 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
operation and result in costly maintenance and
product losses. Please follow the recommendations
listed below when installing drip pipes to
ensure proper installation.
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
1/4 in. per ft (20 mm per 1 m).
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. To meet code on
low base merchandisers, it may be
necessary to install a field-supplied
drip pipe reducer. An alternative is to
cut the last section of drip pipe at an
angle.
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.
