WASTE OUTLET AND WATER SEAL

Each ultra low front case has two waste outlets
located in front of the fan plenum 12 inches
(305 mm) from either end. Water seals are
factory-installed with the waste outlets to prevent
air leakage and insect entrance into the case.
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 case.

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 pipe, PVC fittings, and
PVC primer and glue according to the manufac-
turers' 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.

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
(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.
