tious near the motor and heating elements.

1. Carefully remove your heater from the box. (please save the carton

for off-season storage).

2. Make sure the unit is in the OFF position before plugging the heater

into the outlet.

• Make sure the electrical outlet or circuit breaker is working. 
•  Check for obstructions. If you find an obstruction turn the heater OFF,

and UNPLUG THE UNIT. Carefully remove the obstruction and follow

the reset instructions. 

•  The AccuTemp™ set temperature might be set too low. Raise the

thermostat setting. 

If your heater fails to oscillate:
•  Make sure the oscillation button is switched to the ON position. 

Incorrect Room Temperature Display:
1. Allow a few minutes for the heater to adjust to the room 

temperature.

2. Switch the unit to AccuTemp™ and  use touch pad to set desired 

temperature.

Your heater is equipped with an AccuTemp™ Digital Thermostat that

allows you to set your heater to your precise comfort level.
Setting the AccuTemp™ thermostat:
1.  Make sure the Manual/AccuTemp™ switch is set to AccuTemp™. The

LCD display will read 65°.

2.  Turn the mode control to LO (750 watts) or HI (1500 watts).
3.  Push the temperature set button until the display reads your desired

temperature. To increase the temperature push the top button, for

lower temperatures push the lower button. When finished setting the

temperature, release the button and the display will flash to indicate

the thermostat will be set to that temperature.

4.  The display will return to existing room temperature and gradually

increase until the room has reached your pre-set temperature.

5.  If the unit will not start in the AccuTemp™ mode, please make sure

the “set temperature” is higher than the current room temperature.

NOTE: It is normal for the heater to cycle ON and OFF as it maintains the

preset temperature. To prevent the unit from cycling, you need to raise

the thermostat setting. When the preset temperature is made, the fan

will run for 30 seconds without heat. This cool down process ensures an

accurate and consistent temperature reading. If you unplug the heater,

you will have to reset the AccuTemp™ thermostat again by following the

above instructions.
Manual Operation:
1.  If you want the heater to run continuously, turn the Manual/

AccuTemp

™

switch to Manual and adjust the mode control to LO, or

HI.
