WASTE OUTLET AND WATER SEAL

Each merchandiser has two waste outlets. The
waste outlets are located in front of the fan
plenum 12 inches (305 mm) from either end of
the merchandiser. One water seal, two tees, and
two clean-outs are supplied for each fixture. The
water seal must be installed with the waste out-
lets to prevent air leakage and insect entrance into
the 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.
Optional drip pipe arrangements are shown on
the next page. It is the installing contractor's
responsibility to consult local agencies for local
code requirements. Assemble the components
using field-supplied PVC primer and glue
according to the manufacturers direction.
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 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.

AN AIR LOCK AND PREVENT DRAINING
3. Pitch the drip piping in the direction of flow.
There should be a minimum pitch of
(3 mm per 300 mm).
4. Avoid long runs of drip piping. Long runs
make it impossible to provide the pitch
necessary for good drainage.
