Drip Piping And Splashguards; Waste Outlet And Water Seal; Installing Drip Piping - Hussmann Impact F6 Installation And Operation Manual

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 at the waste outlet to prevent air leak-
age and insect entrance into the fixture.
NOTE:
Water seal outlet must clear front skid rail.
Refer to Data Sheets for dimensions.
A tee fitting, an adapter, a plug and a street ell are
also supplied 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. Improperly installed drip pipes can cause
condensate to form on the outside of drip pipes.
The Water Seal Must Be Level
The residual defrost water in the water seal is a
barrier that will prevent air movement through the
drip piping. Condensation and frost may form if a
water seal is improperly installed.
Refer to the data sheet shipped with each model to
correctly locate piping. Please follow the recom-
mendations 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.

DRIP PIPING AND SPLASHGUARDS

CAUTION
!
Splashguard brackets MUST be installed before
piping case.
2. When connecting drip piping, the water seal
must be used as part of the drip piping to pre-
vent air leakage or insect entrance. The water
seal must be installed with the waste outlet at
the main drain point of each merchandiser.
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
(3 mm per 305 mm).
4. Avoid long runs of drip piping. Long runs
make it impossible to provide the pitch neces-
sary for good drainage.
