2-2 REFRIGERATION / ELECTRICAL

INSULATION

With GAS Defrost
The suction and liquid lines should NOT contact
each other and should be insulated separately
for a minimum of 30 ft (9144 mm) from the
merchandiser.
With OTHER Than Gas Defrost
The suction and liquid lines should be clamped or
taped together and insulated for a minimum of
30 ft (9144 mm) from the merchandiser.
With EITHER of Above
Additional insulation for the balance of the liquid
and suction lines is recommended wherever con-
densation drippage is objectionable or the lines
are exposed to ambient conditions.
FRONT TO REAR AND/OR
END INTERCONNECTS
The wide island merchandisers are factory
equipped with separate piping and air systems
for each compartment, and are thus all capa-
ble of twin-temperature operation. This is a
standard feature.
If the wide island merchandiser is to be run at
a single temperature, factory installed piping
interconnect kits are available.

REFRIGERATION THERMOSTAT

The refrigeration thermostat body is located in
the electrical raceway. The bulb, when factory
installed, is located in the discharge flue. Wide
Island models will have two thermostats – one on
each side of the merchandiser.

DEFROST TERMINATION THERMOSTAT

The standard disc type defrost termination
thermostat is not adjustable. This thermostat
is clamped to the coil inlet tube.

CDA SENSOR (OPTIONAL)

Factory installed optional CDA sensor is located
where the thermostat bulb would normally be
located. Its leads will be routed through the elec-
trical raceway and to the rack control panel.
Leads are tagged in the raceway. Wide Island
models will have two sensors – one on each side
of the merchandiser.
