supply Wiring and Heater Installation
WArNINg:
Wiring procedures and connections should
be in accordance with the National Electric Code (NEC &
CEC) and local codes.
Insert approximately 6” (15.2 cm) of supply wire into
1.
recess box through the desired knockout. Wire should be
rated for a minimum of 75°C (167°F)
Connect power supply to terminals provided marked L1
2.
and L2. Ground wire should be secured to green wire
provided inside of the heater assembly.
WArNINg:
All units are factory prewired for operation
with the built-in thermostat. THIS HEATER IS nOT TO BE
USED WITH A REGULAR WALL THERMOSTAT.
Do a final and complete check of all wiring.
3.
Attach heater by hanging heater on upper tabs then se-
4.
curing at the bottom using the supplied screw.
Insert the air filter through the bottom slot, until it clicks
5.
into place.

WArNINg:
This heater is factory prewired for operation
with the built-in thermostat. THIS HEATER IS nOT TO BE
USED WITH A REGULAR WALL THERMOSTAT.
CAUTION:
This heater must be properly installed before
it is used.
!
NOTE:
Prior to energizing remove all construction dirt
(plaster, sawdust, etc.) from interior and exterior of heater.
The PCH is a Precision Comfort Heater, which maintains a
constant room temperature through the continuous addition
of heat by the blowing of air into the room based on the
setting of the thermostat. The PCH operates such that once
the room reaches the set point, the fan and heater
will
continuously run
at a low level, to maintain the desired
room temperature. If the temperature in the room rises,
i.e. sun coming through a window, the fan will slow further
and the temperature of the heater will reduce so that the
temperature of the room will continue to be the same.
!
NOTE:
The element retains heat after shutdown, there
is a built in cool down period of 2 ½ minutes before the fan
shuts off completely.
WArNINg:
Should the Over Temp light come on, discon-
nect power to the heater and call a licensed electrician.
DO nOT USE HEATER UnTIL THE CAUSE OF THE
PROBLEM IS DETERMInED AnD FIXED.
Dimplex heaters are designed and tested for safe and
trouble-free operation. All Dimplex heaters 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.
!
NOTE:
The unit is designed so that the fan and heater
will run continuously. During normal operation the fan should
be running at a low speed to maintain the room temperature.

(See Figure 3 for display reference)
When power is first supplied to the PCH the Setpoint
Temperature will flash in the temperature display area. At any
time either the
✚
or
–
button can be pressed to have the
temperature setpoint displayed again.
A. setting/Temperature Display
The PCH is designed to control the temperature of a room
anywhere from 32-86°F (0-30°C). By pressing the
✚
or
–
will increase or decrease the desired temperature for the
room to be heated by 0.5° (in either °C or °F).
After 5 seconds the Setpoint Temperature will switch to
display the ambient temperature of the room.
!
NOTE:
Pressing the
✚
and
–
at the same time will toggle
between °C and °F.
B. Comfort setting
The Comfort Setting icon will be displayed when the heater
is in normal operation based on the Setpoint Temperature for
the room.
!
NOTE:
Either the or icon will always be visible,
dependent on the setting being used.
