Operation
WARNING: This heater must be properly installed before it
is used.
1. Prior to powering on the unit, remove all construction dirt
(plaster, sawdust, etc.) from interior and exterior of heater.
2. If the unit is installed using the field-installed built-in
thermostat (CKHATD23), adjust the thermostat with pliers.
This unit can also be controlled from a line voltage single
pole or double pole wall thermostat.
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.
