ELECTRICAL
Check the proposed outlet to be used to insure that the voltage, phase, and current carrying capacity
of the circuit from the electrical panel correspond to the requirements of the cabinet, as shown on the
serial tag. NEVER use an extension cord to wire any unit. On permanently connected units, those not
furnished with a plug-in service cord, all inter-wiring between the electrical panel and the unit must be
done in accordance with the National Electric Code and all state and local codes. Refer to Table 2
and the Serial Tag for all pertinent electrical information.
Observe all Warning Labels. Disconnect power supply to eliminate injury from electrical shock
or moving parts when servicing equipment.

GENERAL OPERATION
The Nova™ Heated Reach-In, Pass-Thru, and Roll-In cabinets employ electrically operated heaters
and a programmable controller to control the temperature. The controller, which is located on the
facade of the unit, is factory set. Please see the default settings sheet and separate instructions that
are included on the operation of this controller. The heating element is located in the interior ducting.
The air ducts provide forced air distribution that maintains temperature uniformity throughout the
cabinet. These cabinets are designed to operate at 180° to 200°F. The programmable controller is
factory set with a maximum set point of 201°F. The temperature control system is designed to cutout
at 230°F to prevent the cabinet from exceeding its design limitations.
GENERAL MAINTENANCE
PERIODIC CLEANING
Beginning with the initial installation, the interior surfaces of the cabinet should be periodically wiped
down with a solution of warm water and baking soda. This solution will remove any odors from
spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with a
commercial grade of glass cleaner.
All moving parts have been permanently lubricated and will generally require no maintenance.
