WASTE OUTLET
A waste outlet is located at the back of the upper
fan plenum, 1
1
/
4
in. (32 mm) from either end of
the case.
It is the responsibility of the installing contractor
to supply and connect drip pipe external to the
case. External drip pipe may be flexible or rigid.
INSTALLING DRIP PIPING
Poorly or improperly installed drip pipes can
seriously interfere with the case’s operation and
result in costly maintenance and product losses.
Please follow the recommendations listed below
when installing drip pipes to ensure proper instal-
lation.
1. Never use drip piping smaller than the nomi-
nal diameter of the pipe in the case.
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.

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
1
/
8
in.
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.
5. Provide a suitable air break between
flood rim of the floor drain and outlet
of drip pipe. To meet code on low base
cases, 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 contact 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 cases or between a
case and a store wall, provide means to
prevent freezing.
SEALING SPLASHGUARD TO FLOOR
Stainless steel splashguards may be sealed to the
floor using a vinyl cove base trim. The size of
trim needed will depend on how much the floor is
out of level.
To install the trim to the splashguard:
1. Remove all dirt, wax and grease from the area
of the splashguard where adhesion will be
necessary. This is to ensure a good and secure
installation.
2. Apply a good contact cement to the cove trim
and allow proper drying time according to the
directions supplied with the cement.
