Drip Piping & Splashguards; Waste Outlet & Water Seal; Installing Drip Piping - Hussmann INSIGHT REACH-IN Installation & Operation Manual

WASTE OUTLET & WATER SEAL
The waste outlet location varies for each for different case lengths.
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. Double water seals in series
will cause an air lock and prevent draining.
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.

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.
