TROUBLESHOOTING

If your heater fails to operate, please follow these procedures:

This heater is intended to be a ceiling/wall-mounted heater. It has a thermal cut-off protection. If the thermal cut-off protection trips, switch off the power. Switch off the circuit breaker. The unit should reset automatically after 10 minutes. If the thermal cut-off protection

trips again, consult a certified/licensed electrician to determine the reason for overheating

Problem Probable Cause Solution

Unit is not heating.

Overheat protection has temporarily deactivated the heater.

Turn the heater OFF. Switch off the circuit breaker. Wait 10-30 minutes before turning on the heater.

Room temperature is higher than the set temperature.

Increase thermostat setting to a higher temperature.

Breaker/Fuse has been tripped. Check your electrical box to confirm the

breaker has not been blown. This may occur if the receptacle is shared with 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 vicinity of 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 room in which heater is situated 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 any adjacent surface/wall.

PLEASE DO NOT ATTEMPT TO OPEN OR REPAIR THE HEATER YOURSELF. DOING SO COULD CAUSE DAMAGE TO THE HEATER OR PERSONAL INJURY.
