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 the 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 setpoint 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.)

1.  Install the Thermostat Outlet Box to the wall. Open the knockout
   on the right.
   

2. Run line voltage wires to the thermostat location via the knock-out. Connect the wires as below image:
   

3.  Insert wires into the Thermostat Outlet Box, and screw up the thermostat.
   

4. Cover the thermostat.

2. Wait for 60 minutes to ensure the heating coil has cooled. Your heater now will be ready for cleaning.

Regular Cleaning

1. Do not spray cleaning liquid or other chemicals on the unit.
2. Interior dust can often be removed by using a vacuum cleaner with a crevice tool attachment.
3.  To clean the enclosure, use a clean, soft, slightly damp cloth to gently wipe off the dirt from the surface of the unit. Make sure that the heating coil and the switches do not get wet. Allow the unit to dry completely before use.

CAUTION: DO NOT ALLOW WATER INTO THE INTERIOR OF THE HEATER AS THIS MAY CAUSE A FIRE OR AN ELECTRICAL HAZARD AND DAMAGE THE UNIT.

TROUBLESHOOTING

If your heater fails to operate, please follow the procedures below.
This heater is intended to be a ceiling-mounted heater. It has a thermal cut- off protection feature. If the thermal cut-off protection trips, switch OFF the circuit breaker. The unit should reset automatically after 10 minutes. If the thermal cut-off protection trips again, consult a certified electrician to determine the reason for overheating.

Switch OFF the circuit breaker. Wait 10 minutes before turning on the heater.
Room temperature has warmed to the thermostat setting.| To increase room temperature, adjust the thermostat control knob to a higher setting.
Breaker/Fuse has been tripped.| Check your electrical box to confirm the breaker has not been blown. This might occur if the receptacle is shared between other high-consumption appliances.
Unit produces 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.| Ensure the room containing the heater is well ventilated.
Ensure a minimum clearance of 1ft (12 inches) from both sides and 4.5 inches from the back.| Reposition the heater so there is enough space between the heater and the adjacent walls.
