Connect the field wiring to the heater wiring as shown in the
wiring diagram.
After connecting the wiring, replace the wiring compartment
cover making sure none of the wires are pinched between the
cover and the heater. Tighten the screws securely.
Optional Plug-in Connection
If this heater is intended to be converted to a cord-connected
model, the QMark model number PHCS1B cord assembly must
be used. Refer to the instructions packed with the cord assem-
bly for installing the cord onto the heater.
HEATING OPERATION
To operate the heater, first select either high or low position on
the heat selector switch, then turn the thermostat knob as far as
it will go in the clockwise direction. The indicator light will come
on and remain on as long as the heater is in the operating
mode. When the room temperature reaches the desired level,
slowly turn the thermostat knob counterclockwise until the ther-
mostat clicks. The indicator light will remain on. The heater will
automatically cycle off and on as needed to maintain desired
temperature. To shut heater off, turn thermostat knob as far as it
will go in the counterclockwise direction until the indicator light is
off.
The fan selector switch allows continuous or cycling fan opera-
tion by selecting either the “ON” or “Auto” position, respectively.
Automatic Fan Delay:
This heater incorporates an automatic
fan delay. When the thermostat calls for heat, fan action is
delayed momentarily until the heating element is warm. When
the thermostat is satisfied, the fan continues to operate until the
heating element is cool. This action prevents circulation of cold
air, and avoids exposing unit to residual heat, thus providing
higher comfort level and prolonged element life.
CLEANING
Turn thermostat off. Disconnect electrical power before cleaning
heater. Use a soft cloth for dusting. For cleaning use only a
damp rag and nonabrasive dish detergent. Do not use abrasive
or chemical cleaners as these may harm the finish.
If heater is used in a very dusty location, use a vacuum cleaner
dust brush to remove dust and other foreign material from the
grilles.
