Use the heater only as described in the manual to prevent fire, electric shock, or injury.
If the visual alarm on the heater flashes, immediately turn off the heater and inspect for any objects on or adjacent to the heater that may cause high temperatures. Do not operate the heater with the alarm flashing. To reset the heater, switch the circuit breaker off and wait for the unit to cool down before turning it back on.

OPERATING INSTRUCTIONS

WARNING! The heater must be properly installed before use. HAZARD OF ELECTRIC SHOCK,

EXPLOSION OR ARC FLASH:

Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70.
A circuit breaker must be installed and serviced only by a certified electrician.
Always use a properly rated voltage-sensing device to confirm that the power is OFF.

The HIGH/LOW switch on the heater is only for setting selection. Use the circuit breaker as the Power ON/OFF switch for the heater. The circuit breaker is to be installed by a certified electrician and should be located in line- of-sight from the heater location, or it should be capable of being locked in the open position. Follow the operating instructions to reduce the risk of fire, electric shock, injury, or death.

To turn on the heater, switch on the circuit breaker.
- Then turn the thermostat to the farthest clockwise position. The fan should start, the unit will begin heating the room, and the lamp will light.After the room reaches a comfortable level, turn the thermostat counterclockwise until the heater shuts off. The heater will cycle automatically around this preset temperature. To increase the temperature, turn the thermostat knob clockwise. To lower the temperature, turn the thermostat counterclockwise.
Toggle the HIGH/LOW switch to change the heat setting. HIGH: 6000W
- LOW: 3000W
Select a thermostat setting. Ambient temperature is regulated by adjusting the thermostat to a desired position. Allow the unit to operate and warm up the room. When the desired temperature is reached, turn the control knob counterclockwise until the heater turns off. This is your ideal setting. The heater will start automatically when the room temperature drops below this set point, and will turn off when the set point is reached.
To turn off the heater, switch off the circuit breaker. The circuit breaker serves as the only means of disconnecting power from the heater.
This heater includes a visual alarm to warn that parts of the heater are becoming excessively hot. If the alarm flashes, immediately turn the heater OFF and inspect for any objects on, in, or adjacent to the heater that may cause high temperatures. DO NOT OPERATE THE HEATER WITH THE ALARM FLASHING. To reset the heater, switch the circuit breaker OFF, and wait five to ten minutes for the unit to cool down before turning the heater on again.
How to install Wall Thermostat. (DR-001 Not Included.)
