IMPORTANT INSTRUCTIONS
SPECIFICATIONS
Read all instructions before installing or using this heater.
This heater is hot when in use. To avoid burns keep bare skin away from hot surfaces.
Keep combustible materials, such as electrical cords, furniture, pillows, bedding, papers,
clothing, and curtains at least 3 feet (0.9 m) from the front of the heater and keep them
away from the sides and rear.
Extreme caution is necessary when any heater is used by or near children or invalids and
whenever the heater is left operating and unattended.
Always switch off the power to the heater when not in use.
Do not operate any heater if it is faulty, has been dropped or damaged in any manner.
Disconnect the power supply at the service panel and have the heater inspected by a
reputable electrician before reusing.
Do not use outdoors.
This heater is not intended for use in bathrooms, laundry areas or similar indoor locations.
Never locate the heater where it may fall into a bathtub or other water container.
Do not push objects of any kind into the ventilation or exhaust openings as this may result
in electric shock, fire or damage to the heater.
To prevent the risk of fire, do not block the air intake or exhaust openings in any way. Do
not use on soft surfaces, like a bed, where openings may become blocked.
A heater has hot parts inside that may arc or spark. Do not use it in areas where gaso-
line, paint, or flammable liquids are used or stored.
Use this heater only as described in this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or personal injury.
To disconnect the heater, turn the device off, and turn off the power to the heater circuit
at the main disconnect panel.
This heater may include a visual alarm to warn that parts of the heater are getting exces-
sively hot. If the alarm illuminates, immediately turn the heater off and inspect for any
objects on or adjacent to the heater that may have blocked the airflow or otherwise
caused high temperatures to have occurred. DO NOT OPERATE THE HEATER WHILE
THE ALARM LIGHT ILLUMINATING.
When using electrical appliances, basic precautions should always be taken to reduce the
risk of fire, electric shock, and personal injury, including the following:
WARNING TO PET OWNERS:
The health of some small pets, including birds, is extremely sensitive to the fumes produced
during the first-time use of many appliances. These fumes are not harmful to humans but we
recommend that you do not use your heater around birds and small pets during its initial use
until the manufacturing corrosion coatings have burned off.

Use only copper wires rated for at least 60°C.
The air flow from the heater must be directed parallel to or away from the adjacent wall.
Observe all wall, floor and ceiling clearance requirements.
All wiring must comply with national and local electrical codes. The heater must
be grounded as a precaution against possible electric shock.
The heater circuit must be protected with proper fuses.
The mounting structure and fixing hardware must be capable of supporting the weight of
the heater and the mounting bracket (if used).
All electrical power must be disconnected from the main service box, which must be
locked before connecting, inspecting, cleaning or servicing the heater. This is an import-
ant precaution to prevent serious electric shock.
This is heater is not suitable for use in hazardous areas containing explosive liquids or
vapors. This heater has hot, arcing or sparking pads inside. Do not use it in areas
where gasoline, paint or flammable liquids are used or stored.
This heater is not suitable for use in corrosive atmospheres such as marine greenhouses
or chemical storage areas.
This heater must be mounted at least 8 feet above the floor. For specific clearances,
please see the next page.

SAFETY INFORMATION
3 4
Install the heater away from traffic areas, maintaining the clearances shown in Figure 1
(below). The air flow direction should not be restricted (e.g., by columns or machinery). The
airflow should wipe exposed walls rather than blowing directly onto them. Where more than
one heater is used in an area, the heaters should be installed so that the air discharge from
each heater supports the air flow of the others, to provide best warm air circulation as shown
in Figure 2.

must install a piece of wood on the ceiling as this heater must be securely fastened.
Remove the mounting bracket from the heater unit by loosening the bracket screws with a
wrench and sliding the handle off over the screw heads.
Place a washer on the screws before inserting them through the holes in the mounting
bracket and screw them securely into a ceiling joist.

the heating element first will turn off then the fan will run a short cooling cycle and then turn
off.
TO PROTECT THE HEATER
NOTE: All wiring must be carried out by a qualified electrician and must be in accordance to
national and local electrical codes. For certain applications, conduit may be required, see
Figure 6. Check local electrical codes. If you are running the wiring in conduit and wish to be
able to turn the heater, be sure to purchase enough flexible conduit to allow the heater to be
rotated.
CONNECTING THE POWER
THIS APPLIANCE MUST BE GROUNDED!
THE APPLIANCE MUST BE CONNECTED TO A CURRENT PROTECTION CIRCUIT OR
DEVICE AT 50AMP OR LESS BEFORE BEING CONNECTED TO POWER SUPPLY!
Warning

THE HEATER MUST BE PROPERLY INSTALLED BEFORE IT IS USED.
Warning
1. Main Power Button:
This button adjusts the 3 heating levels: OFF, FA (Fan Only), AU: LOW (6400W displays "L")
or High (8500W displays "H").
2. Heater Control Button:
This LED display shows the set point for the temperature and timer functions. When either of
these functions is activated, the display will show the set point for about 10 seconds and
then fade to black. Any change to the set point of the temperature or timer set point reacti-
vates the display, which then disappears after approximately 10 seconds.
3. Temperature/Timer Display:
This button controls the Timer OFF (no display) and 8 settings from 1 to 8 hours. When the
Timer is turned on, it will come on at the shortest time setting (1hour). Each time the Timer
button is pressed, the time increases by 1 hour, up to the longest setting (8 hours). Once the
set time expires, all garage heaters functions will be automatically turned off.
5. Timer Button:
REMOTE:
▼ DOWN Control Button: Only in "AU" mode, this button is used to decrease temperature.
▲UP Control Button: Only in "AU", this button is used to increase temperature.
GARAGE HEATER :
Only in "AU", this button is used to increase the temperature setting. To switch from Fahren-
heit to Celsius, or vice versa, hold this button for 3 seconds.
The temperature range is between 10°C - 35°C (50°F - 95°F) in 1-2°F (1°C) increments. In the
AU (H/L) gear, when the set temperature more than or equal to ambient temperature 0
degrees but less than or equal to 5 degrees, the heater will be switched to low power to save
energy. The heater is firing high power only when the set temperature is out of 5 degrees
range. Until the ambient temperature is more than the set temperature, the heater will stop
heating, but the fan will stop working after 60 seconds.

Before cleaning, make sure that the power is switched off at the circuit breaker panel and
that the heating element of the heater is cool.
To maintain the external appearance of the heater it is necessary to occasionally wipe the
unit with a dry cloth. During the summer months, or at other times when the appliance is
not in use and is completely cold, it should be wiped over with a damp cloth.
Do not use abrasive clearing powders or furniture polish. Do not use chemical or abrasive
products, metal scourers, etc., to clean the unit as they may damage the surface.
Disconnect the power supply during the summer months or when not in use. Store the
unit in a dry and cool place.
All other services should be carried out by qualified service personnel. Do not try to repair
the heater yourself.
