Qmark CWH3000 Series - Commercial Fan-Forced Wall Heaters - Manual (Page 4)

OPERATING
INSTRUCTIONS
1. Heater must be properly installed before operation.
2. Rotate the thermostat knob fully clockwise. This should
energize the heating elements and fan causing warm air to
flow from the hot air discharge at the openings in the bottom
of the grille. (see note 5)
3. After the operation check, rotate the thermostat knob to the
desired position to obtain room comfort.
4. For continuous fan-only operation (heating elements will not
be energized), slowly rotate the thermostat knob clockwise
until you hear the fan operate (about 30 degrees from the
OFF point).
5. There will be a short delay from the time the unit is turned on
until the fan engages. This is to allow the elements time to
warm up. The fan will also continue to run once the unit is
turned off to allow the elements time to cool.
NOTE: For best results, the heater should be left “ON”
constantly during the heating season because the thermostat,
when properly set, will maintain the desired temperature.
How To Reset Manual Thermal Overheat
Protector Control:
Your heater is equipped with a manual reset thermal overheat
protector control that will automatically turn the heater off to
prevent a fire if the heater overheats. This control is located on
the fan panel assembly between the element and fan blade and
marked “
RESET”. The red reset button can be seen through the
front grille when the heater is installed. To reset, allow the heater
to cool, then push the red button that is visible through the hole
in the fan panel. The heater should immediately return to normal
operation.
