Operation
WARNING: This heater must be properly installed
before it is used.
1. Prior to energization remove all construction dirt
(plaster, sawdust, etc.) from interior and exterior of
heater.
2. Adjust thermostat with pliers. This unit is also
controllable from a line voltage wall thermostat or
field installed built-in tamperproof single or double

Dimplex Under Cabinet heaters are designed and tested
for safe and trouble-free operation and are protected
against overheating by a built-in thermal cutout. Free
airflow throughout the heater is extremely important for
the most efficient operation of the heater. Restricted
airflow may cause the thermal overload protector to
cycle the heater "ON and OFF". A cycling heater will not
supply sufficient heat to the room.
Avoid direct contact of paper, fabric, or furniture with
heater.
