WARNING -The heater must be properly installed before it is used.
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 qualified electrical personnel.
Always use a properly rated voltage sensing device to confirm power is off.
The Select switch on the heater is only for function selection. Use circuit
breaker as power ON/OFF device. The circuit breaker is to be installed by
certified electrican and shall be located in line of sight from the heater location
or shall be capable of being locked in open position. Follow the operating
instruction to reduce the risk of fire, electric shock, injury or death to persons.
Switch on the circuit breaker to turn on the heater.
Then turn the thermostat to the farthest clockwise position. The fan should start and the unit
begins heating the room, and lamp is light. After the room reaches comfort level, turn the
thermostat counterclockwise until the heater shuts off. The heater will automatically cycle around
this preset temperature. To increase the temperature, turn the thermostat knob clockwise. To
lower the temperature, turn the thermostat counterclockwise.
Press the switch to High or Low position for heat selection.
HIGH : 7500W
LOW : 4700W
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 power disconnection means.
This heater includes a visual alarm to warn that parts of the heater are getting excessively hot. If
the alarm flashes, immediately turn the heater OFF 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 five to ten
minutes for the unit to cool down before turning the heater on.

heating.
Overheat protection has temporarily
deactivated the heater.

if the receptacle is shared between other
high consumption appliances.
The heater is
producing a
burning
smell.
Check & ensure there are no
combustible materials within 0.9
meters (3 feet) surrounding the heater. Remove any combustible items from the
heater.
A drop of oil fell on the heating coil
during the manufacturing process. It
will quickly evaporate and should not
occur again.
