1.
Turn the switch ON. Remember there is a fan delay.
2.
Set thermostat by turning the knob to desired room comfort level
(clockwise to increase heat output). Once you have determined
the proper setting to provide the heat level you prefer, you need not
touch the knob again.
3.
Turn the switch OFF to turn off heater. To reuse, simply turn the
switch ON - the temperature level you wish has been previously
set.
NOTE: This heater is equipped with a fan delay switch which delays
the fan operation until the heating grid has heated sufficiently to
assure the circulation of only warm air. This same switch permits
the fan to operate after power to the grid has been shut off by
thermostat action, thus utilizing all the heat remaining in the grid.
When the heater is shut down by turning the switch OFF, power to
both fan motor and element is diconnected and the fan motor will
not continue to operate.
WARNING: Should the OVERTEMP light come on, disconnect power to
the heater, turn the switch OFF or turn down the thermostat fully
counterclockwise and call a licenced electrician. DO NOT USE
HEATER UNTIL PROBLEM IS DETERMINED AND FIXED.
