CONTROL SETTINGS

Merchandiser data sheets are shipped with this
manual. The data sheets provide case control
settings and defrost data.

An evaporator pressure regulator or EPR
(primary control) and a 3 – 5ºF (1.7 – 2.7ºC)
differential thermostat (secondary control) must
control refrigeration temperature. The EPR must
be set to maintain the proper saturated evaporator
temperature as listed in the data sheets. The
thermostat must be set a couple degrees colder
than the discharge air temperature specified in the
data sheets. The thermostat will prevent product
freezing should the EPR temperature drift
downward during reduced load periods (lights
off, lower ambient). The thermostat will be wired
to control the compressor motor contactor (single
compressor) or a liquid line solenoid valve
(parallel compressor systems).

Defrost is Off Time. Defrost control settings are
listed in the data sheets. When these merchan-
disers are connected to parallel compressor
systems, a suction stop valve must be used to
isolate the evaporator during defrost periods.

REFRIGERATION THERMOSTAT

The bulb for the optional refrigeration thermostat
is located in the discharge air of the evaporator.
The optional refrigeration thermostat is located
behind the exterior rear panel.

DEFROST TERMINATION THERMOSTAT

The standard disc type defrost termination
thermostat is not adjustable. This thermostat
is clamped to the inlet of the coil on the left-
hand (facing front) end of the merchandiser.
