WASTE OUTLET AND WATER SEAL
The waste outlet location varies for each of the 1,
2, 3, 4, and 5 door merchandisers. Drip piping is
located between the front case base and the
splashguard fixture and runs parallel to the case
(see Data Sheet for exact locations).
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 pipes to ensure proper
installation.
1. Never use drip piping smaller than the nomi-
nal diameter of the pipe or water seal sup-
plied with the merchandiser.
2. When connecting drip piping, the water seal
must be used as part of the drip piping to pre-
vent 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
inch
per foot (1 mm per 100 mm).
4. Avoid long runs of drip piping. Long runs
make it impossible to provide the pitch neces-
sary 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 non-absorbent 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.
