Drip piping must be installed for cases without
evaporation pans. 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.

• Pitch the drip piping in the direction of
flow. There should be a minimum pitch of
1
/
4
in. per ft (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.
OPTIONAL DRIP PIPING
Splashguard
brackets
MUST be installed
before piping merchandiser.
