WASTE OUTLET AND WATER SEAL
Each ultra low front merchandiser has two
waste outlets located in front of the fan
plenum 12 inches (305 mm) from either end .
Water seals are factory-installed with waste
outlets to prevent air leakage and insect
entrance into the merchandiser . Do not
remove the guard installed under the water
seal—it prevents damage during shipment,
installation and use . Two tees and clean-outs
are supplied for 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 .
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 pipe,
PVC fittings, and 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 .

runs make it impossible to provide the pitch
necessary for good drainage .
