NSTALLATION
REFRIGERATION
(Self Contained Models)
Each self contained model is equipped with
its own condensing unit and control panel
located beneath the display area. The correct
type of refrigerant will be stamped on each
merchandiser's serial plate. The merchandiser
refrigeration piping is leak tested. The unit is
charged with refrigerant, and shipped from
the factory with all service valves open.
GSVM models have a refrigeration system
that uses a hermetic compressor. GSVM-4060
and GSVM-4072 systems use a capillary tube
for refrigerant control. The capillary tube is
soldered to the suction line pull-out coil for
proper heat exchange. If the capillary should
become plugged or damaged, it is best to replace
the heat exchanger.
GSVM-5272 employs a bleed port type
expansion valve for proper refrigerant
control. Read the merchandiser's serial plate
for the appropriate refrigerant type and
weight.

WATER OUTLET AND WATER SEAL
GSVM models 4072 and 5272 require a floor
drain. The condensate water outlet is located in
the center of the merchandiser. The outlet has
a factory installed, external water seal.
For self contained models like GSVM-4060,
this water seal drains into a high-humidity
electric condensate pan located beneath the
merchandiser. The pan uses a thermistor that
senses water in the pan, adjusting the amount
of heat required to evaporate the water. Ensure
the drain hose is properly trapped, and the drain
area is not clogged.
NOTE: All lower base panels must be in place
when the refrigerator is operating. If not, airflow
from the condenser will be directed over the evapo-
rator pan and defrost water in the pan may over-
flow.
OPTIONAL ELECTRIC
CONDENSATE PAN
An optional high-humidity condensate pan kit
requires a dedicated 15 Amp circuit - 120V
(GSVM-4072 and GSVM-5272).
