LOCATION –
Like other open merchandisers, these are
sensitive to air disturbances. Air currents pass-
ing around merchandisers will seriously impair
their operation. Do NOT allow air conditioning,
electric fans, open doors or windows, etc. to cre-
ate air currents around the merchandisers.
REAR CLOSE-OFF PANEL –
To perform electrical and refrigeration
work, remove the rear closure panel by removing
the sheet metal screws. Replace when work is
complete.
NOTE: Self Contained Models - Do note block
the vent openings on the rear closure panel.
These allow intake and exhaust air for the con-
densing unit. Vents only appear on self-
contained models.
CONDENSATE REMOVAL – Self Contained
On the self contained merchandisers the
waste outlet is centrally located and accessible
from the rear of the case.
The condensate water from the evaporator
drains out through the bottom of the evaporator
compartment into the condensing unit area into
a heated condensate pan.
The pan has a float that activates the
heater when sufficient water is in the pan.
INSTALLING DRAIN PIPING – Remotes
Poorly or improperly installed drip pipes
can seriously interfere with the merchandisers’
operation and result in costly maintenance and
product losses. Please follow the recommenda-
tions listed here when installing drip pipes to en-
sure proper installation.
1. Never use drip piping smaller than the
nominal diameter of the pipe or water
seal supplies with the merchandiser.
2. When connecting drip piping, the “water
seal” must be used as part of the drip pip-
ing to prevent air leakage or insect en-
trance. 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.
3. Pitch the drip piping in the direction of
flow. There should be a minimum pitch of
1/8” per foot
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.
6. Prevent drip pipes from freezing:
a. Do not install drip pipes in contact
with insulated suction lines. Suction
lines should be insulated with a nonab-
sorbent insulation material.
b. When drip pipes are located in dead
air spaces, such as between merchan-
disers or between a merchandiser and
a store wall, provide means to prevent
freezing.
