WASTE OUTLET AND WATER SEAL

The waste outlet location varies for each of the 1, 2,
3, 4, and 5-door merchandisers. Drip piping is located
between the front merchandiser base and the splashguard
fixture and runs parallel to the merchandiser (see Data
Sheet for exact locations).

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. Please follow
the recommendations listed below when installing drip
pipes to ensure proper installation.
• Never use drip piping smaller than the nominal
diameter of the pipe or water seal supplied with
the merchandiser.
• 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
seals in series will cause an air lock and prevenT

• Pitch the drip piping in the direction of flow.
There should be a minimum pitch of
(20 mm per 1 m).
• Avoid long runs of drip piping. Long runs make it
impossible to provide the pitch necessary for good
drainage.

• 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.
• Prevent drip pipes from freezing sweating or freezing:
A. Do NOT install drip pipes in contact with
uninsulated suction lines. Suction lines should be
insulated with a non-absorbent 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 drip pipe from sweating. External
ventilation fans may be required to prevent
sweating.
