ELECTRICAL CIRCUIT IDENTIFICATION
Standard lighting for all models will be full length fluores-
cent lamps located within the case at the top.
The switch controlling the lights, the plug provided for
digital scale, and the thermometer are located at the rear
of the case mullion.
The receptacle that is provided on the exterior back of
these models is intended for computerized scales with a
five amp maximum load, not for large motors or other
high wattage appliances. It should be wired to a dedicated
circuit.
BEFORE SERVICING
ALWAYS DISCONNECT ELECTRICAL
POWER AT THE MAIN DISCONNECT
WHEN SERVICING OR REPLACING ANY
ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heat-
ers, Thermostats, and Lights.
FIELD WIRING & SERIAL PLATE AMPERAGE
Field Wiring must be sized for component amperes
printed on the serial plate. Actual ampere draw may be
less than specified. Field wiring from the refrigeration
control panel to the merchandisers is required for re-
frigeration thermostats. Most component amperes are
listed in the “Case Specs” section, but always check the
serial plate.
BALLAST LOCATION
Ballasts are located within the access panel that runs
the length of the rear of the case.
T-STAT LOCATION
The T-stats are located within
the electrical raceway. The
raceway location is dependent
on the style of the front panel
and whether the case is going
to be pushed up against a wall.
(See diagram.)
In all cases, the T-stat is located
on the same side of the case. If
you are looking at the case
from the front, it is the right-
hand side. If you are looking at
the case from the back, it is the
left-hand side.

or evaporation temperature to 15°F by the method engi-
neered into your system. A thermostat is located on the
top of thje case for temperature control. Set the thermo-
stat to cycle in and out as per the Case Specification sec-
tion of the guide. Set the timeclock to
Finishing Touches
If more than one RED is being installed next to each other,
the factory fitted continuous fascia may need to be in-
stalled. All fasciae rest on the top of their cases. The self-
contained fascia has a hook that needs to be slid through
a gusset on the side of the case.
