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 outlets 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
operation 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
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.

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.
