IMPORTANT INSTRUCTIONS
PLEASE READ ALL INSTRUCTIONS BEFORE USING THIS HEATER
NOTE: There may be a trace of smoke or odor when unit is first operated. Don’t be alarmed.
This indicates that a drop of oil fell on the heating coil during the manufacturing process. It
will quickly evaporate and should not re-occur.
Make sure that the room in which the appliance is located is well ventilated during this
operation. It is normal for the appliance to emit small cracking sounds when you turn it on for
the first time. Do not be alarmed.
WHEN USING ELECTRICAL APPLIANCES, BASIC PRECAUTIONS SHOULD ALWAYS BE
FOLLOWED TO REDUCE RISK OF FIRE, ELECTRICAL SHOCK AND INJURY TO PERSONS OR
PROPERTY, INCLUDING THE FOLLOWING:
1) Read all instructions before using this heater.
2) This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Keep
combustible materials, such as furniture, pillows, bedding, papers, clothes, and curtains at least
3’ (0.9 m) from the front of the heater and keep them away from the sides and rear.
3) Extreme caution is necessary when any heater is used by or near children or invalids and
whenever the heater is left operating and unattended.

adjacent vertical surfaces or walls. Keep at least 4.5 inches (11.5 cm) from the back wall (with or
without using the wall hanging mounting bracket).
9) Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause
an electric shock or fire, or damage the heater.
10) To prevent a possible fire, do not block air intakes or exhaust in any manner.
11) A heater has hot and arcing or sparking parts inside. To reduce the risk of fire, do not use it in

Knock-out hole
16. Make the connections properly with connectors which are suitable for the conductor size, in
cluding grounding wirings.
Pull all the conductors from the conduit. Strip 3/4 inch of insulation from ground conductors. Make
a right angle bend in the green(green/yellow) pigtail and place its stripped end next to the stripped
ends of the other green(green/yellow) supply cable. Make sure that the bare ends are tight
together and square. Using lineman's pliers, twist the bare ends tightly together in a clockwise
direction, then screw one of the wire nuts tightly on the spliced conductors. Check to be sure that
no bare copper shows from beneath the wire nut.
17. For the rest of the supply cable, strip 0.4inch (10mm) of the isulation.
18. Identify the supply cables’ phase and insert into respective L1, L2, L3 terminal. Secure the hex
nuts.
19. And after making the connections, arrange the pigtail leads of unit and power supply wires in the
wiring compartment.
20. Replace the wiring cover and lock in place with the screw.
21. Consult NEC code for other types of approved electrical wire splices & wire connectors.
Single and 3 phase connection:
1. This heater is capable to connect with single phase or 3 phase power.
2. Check the power source and use the correct wiring for connection.
3. The heater is factory wired with single phase, if your power source is single phase, it will be OK
that you start make supply connections.
4. Open the access window.
5. Connect the 2 supply cords to L1 and L3.
6. Replace the cover and lock in place with the screw.
7. For a 3 phase connection, wiring has to modify.
8. Open the access window. Look for the internal wires which mark T and W.
9. Unplug T and plug to the Terminal T1 position.
10. Unplug W and plug to the Terminal W position.
11. Now the heater is of 3 phase wiring.

OPERATING INSTRUCTIONS
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
workpractices. 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 switch on the heater is to start the Fan and Heater. Use the 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 power.

Press the switch at the back of the heater to turn on the fan and heating function.
 To turn off the heater, press the switch turn off the fan and heating function. And then

Temperature setting
The heater is capable to connect to an external wall thermostat. If a wall thermostat has been connected
to the heater. Make sure which thermostat is in use. There is the selector switch:
“ I ” position is the internal thermostat.
“ II ” position is the external thermostat.
How to select a thermostat setting:
Using the build in temperature controller (build in thermostat):
Note: The selector switch must be at the position I.
1. Ambient temperature is regulated by adjusting the build in thermostat to a desired position.
2. Allow the unit to operate and warm up the room.
3. When the desired temperature is reached, turn the control knob counterclockwise until the heater
turns off. This is your ideal setting.
4. The heater will start automatically when the room temperature drops below this set point, and will
turn off when the set point is reached.
Using an external temperature controller (a wall thermostat):
Note: The selector switch must be at the position II.
1. To use an external temperature controller (a wall thermostat), follow the installation instruction
to connect the wall thermostat first.
2. Press the selector switch from position I to II. Now wall thermostat is selected and the build in
thermostat is being disconnected.
3. Ambient temperature is regulated by adjusting the build in thermostat to a desired position.
4. Allow the unit to operate and warm up the room.
5. When the desired temperature is reached, turn the control knob counterclockwise until the heater
turns off. This is your ideal setting.
6. The heater will start automatically when the room temperature drops below this set point, and will
turn off when the set point is reached.

MAINTENCE AND CLEANING
There is no user maintenance part except regular cleaning as following description. All other
servicing or maintenance should be performed by qualified service personnel.
Before any cleaning, make sure that:
1. Disconnect power supply at source. Switch off the circuit breaker.
2. Wait for 60 minutes to ensure the heating element has cool down, and your heater is now ready
for cleaning.
Regular Cleaning:
1. Do not use cleaning liquid or other chemicals to spray on the unit.
2. Interior dust can often be removed by using a vacuum cleaner with a crevice tool attachment.
3. To clean enclosure, use a clean, soft and lightly damp cloth to gently wipe off the dirt from the
surface of the unit. Be sure not to wet the heating element and the switches. Allow the unit to dry
completely before using it.
CAUTION: DO NOT ALLOW WATER TO RUN INTO THE INTERIOR OF THE HEATER AS THIS
COULD CREATE A FIRE OR ELECTRIC SHOCK HAZARD, DAMAGING THE UNIT.
TROUBLESHOOTING
If your heater fails to operate, please follow these procedures:
This heater is intended to be a ceiling-mounted heater. It has a thermal cut-off protection. If the
thermal cut-off protection trips, then, 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 electrician to determine the reason for overheating.
Problem
Unit is not
heating.
The heater is
producing a
burning smell.
Probable Cause
Solution
Overheat protection has temporarily
deactivated the heater.
Turn the heater OFF; Switch off the circuit
breaker.. Wait 10 minutes before turning on the
heater
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 between other high consumption appliances.
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 a minimum clearance of 4.5 inches
(11.5 cm) from both sides and rear of heater
to adjacent walls.
Ensure room in which heater is situated is well
ventilated.
Reposition the heater so there is enough space
around the heater to the adjacent walls.
PLEASE DO NOT ATTEMPT TO OPEN OR REPAIR THE HEATER YOURSELF. DOING SO COULD
CAUSE DAMAGE OR PERSONAL INJURY.
