WASTE OUTLET AND P-TRAP
The waste outlet is located off the center of the case
on one side allowing drip piping to be run lengthwise
under the fixture.
A 7/8" copper P-trap is supplied with each fixture. The
P-trap must be installed to prevent air leakage and
insect entrance into the fixture.
NOTE: PVC-DWV solvent cement is recommended.
Follow Hussmann’s instructions.
INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can
seriously interfere with the operation of this re-
frigerator, and result in costly maintenance and product
losses. Please follow the recommendations listed below
when installing condensate drains to insure a proper
installation:
1. Never use pipe for condensate drains smaller than
the nominal diameter of the pipe or P-trap supplied
with the case.
2. When connecting condensate drains, the P-trap
must be used as part of the condensate drain to
prevent air leakage or insect entrance. Store plumb-
ing system floor drains should be at least 14" off the
center of the case to allow use of the P-trap pipe
section. Never use two water seals in series in any
one line. Double P-traps in series will cause a lock
and prevent draining.
3. Always provide as much down hill slope (“fall”) as
possible; 1/8" per foot is the preferred minimum.
PVC pipe, when used, must be supported to main-
tain the 1/8" pitch and to prevent warping.
4. Avoid long runs of condensate drains. Long runs
make it impossible to provide the “fall” necessary for
good drainage.
5. Provide a suitable air break between the flood rim of
the floor drain and outlet of condensate drain. 1" is
ideal.
6. Prevent condensate drains from freezing:
a. Do not install condensate drains in contact with
non-insulated suction lines. Suction lines should be
insulated with a nonabsorbent insulation material
such as Armstrong’s Armaflex.
b. Where condensate drains are located in dead air
spaces (between refrigerators or between a
refrigerator and a wall), provide means to prevent
freezing. The water seal should be insulated to
prevent condensation.
LOCATION
The refrigerated merchandisers have been designed for
use only in air conditioned stores where temperature
and humidity are maintained at or below 75
°
F and 55%
relative humidity. DO NOT allow air conditioning,
electric fans, ovens, open doors or windows (etc.) to
create air currents around the merchandiser, as this will
impair its correct operation.
Product temperature should always be maintained at a
constant and proper temperature. This means that from
the time the product is received, through storage,
preparation and display, the temperature of the product
must be controlled to maximize life of the product.
UNCRATING THE STAND
Place the fixture as close to its permanent position as
possible. Remove the top of the crate. Detach the walls
from each other and remove from the skid. Unbolt the
case from the skid. The fixture can now be lifted off the
crate skid. Lift only at base of stand!
SETTING AND JOINING
LEVELING
IMPORTANT! It is imperative that cases be leveled
from front to back and side to side. A level case is
necessary to insure proper operation and water
drainage.
Installation
Counter Installation
1. Be sure to level the counter where the case is to be
installed.
2. Cut a hole in the top, 25” deep x appropriate length
(Standard cases come in 4’, 5, and 6’ lengths.
3. Apply a bead of silicone around the opening.
4. Slide the unit into the hold.
Counter Requirements
Ventilation must be provided for exhaust and intake air.
Condensing Unit Installation Requirements
For proper operation of the Condensing Unit provide
an opening with adequate exhause and intake as fol-
lows:
≤
1 1/2 hp:
minimum of 2 vents totalling 150 sq. in.
≥
1 1/2 hp: minimum of 2 vents totalling 200 sq. in.
It is the contractor’s responsibility to install
case(s) according to local construction and
health codes.
