WASTE OUTLET AND WATER SEAL
The waste outlet is located in front of the fan
plenum 6 ft (1829 mm) from the left-hand end
of the merchandiser (facing case front). A water
seal is supplied with each fixture. The water seal
must be installed to the waste outlet to prevent
air leakage and insect entrance into the fixture.
NOTE:
Water seal outlet must clear front skid rail.
A Tee, adapter, plug and street ell are also sup-
plied with each 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. 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. 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
per ft (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.

CAUTION
!
Splashguard brackets MUST be installed
before piping case.
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 con-
tact with uninsulated suction lines. Suction
lines should be insulated with a nonabsorbent
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.
