This unit is equipped with two on/off switches located behind the
louvered machine compartment door. The unit’s com pres sor and
all evaporator fans will begin op er at ing when this switch is turned
to the
“on”
position. Tem per a ture ranges for the base are 36° to
40° F.
The switch labeled rail is for the raised rail.
Turning this switch
to the
“on”
position will activate the refrigeration for the rail.
Temperature ranges for the raised rail are 33°F to 41°F.
Product located in the rail must be removed to the
re frig er at ed base at the end of day. This allows you
to turn the rail off at night to save energy and the rail
will have time to defrost as needed. It also helps to
maintain product quality.
A minimum of one hour of off time per day with the pans
removed from the rail is required to properly defrost the rail. If pans
are left in the rail, it may take up to four hours to defrost under
the pans. Product left in the rail during a four hour off period will
experience a significant rise in tem per a ture and may not be suitable
for use.
Be sure to turn the rail switch to the “on” position in the morning
when you return the pans to the raised rail.

disconnected from the power source whenever
performing service or maintenance functions.

investigated by a qualified refrigeration technician.
