Before installing and operating this product, the user and/or installer must read, understand and follow these instructions and keep them handy for future reference. If these instructions are not followed, the warranty will be considered null and void and the manufacturer deems no further responsibility for this product.
This product must be installed by a qualified person and connected by a certified electrician , according to the electrical and building codes effective in your region.
Make sure that all screws and electrical terminal connections are tightly secured before operating the unit in case they would have loosened during transportation.
The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries, and potentially fatal electric shocks.
Make sure that all screws and electrical terminal connections are tightly secured before operating the unit in case they would have loosened during transportation.
Protect the heating unit with the appropriate circuit breaker or fuse, in accordance with the nameplate.
Make sure the line voltage (volt) is consistent with that indicated on the unit’s nameplate.
This unit must be grounded. Switch off the power at the circuit breaker/fuse before installing, repairing and cleaning the unit.
Make sure the unit is appropriate for the intended use (if needed, refer to the product catalog or a representative).

RECOMMENDED HEATING CAPACITY:
1.25 W/cubic foot (0.03 m³).
It corresponds to 10 W/square foot (0.09 m²) based on a standard ceiling height of 8 feet (2.44 m). Do not install the unit where objects or pieces of furniture could be heat damaged.
If the unit’s capacity is insufficient for the size of the room, it will be in operation continuously, and may become defective earlier and turn yellow. Respect distances and positions indicated in the installation section. If the installer or user modifies the unit, they will be held responsible for any damage resulting from this modification, and the CSA certification could be void. This unit must not come into contact with a water source and must be protected from splashes (e.g. a wet mop). Do not use it if any part has been immersed. Moreover, do not turn it on or off when standing in water or if your hands are wet.
When cutting or drilling into a wall, do not damage electrical wiring and other hidden utilities.
Do not install this product on walls made of synthetic material such as, but not limited to, carpet and wallpaper.
When starting up the unit for the first time or after a long period, it is normal that it produces some temporary odours and whitish smoke. Because this unit is hot when in use, it may pose risks even in normal operation. Therefore, be careful and responsible when using it. To avoid burns, do not let bare skin touch hot surfaces. Let the unit cool down for few minutes before handling (it will stay warm for some time after shut-down).
It is the user’s responsibility to ensure that objects including, but not limited to, shelves or plastic containers do not come in contact with the unit and to keep them at least 24 inches (61 cm) from the unit. Never block air vents. This obstruction could lead to overheating, which could result in a fire. Do not insert or allow foreign objects to enter any air vent as this may cause electric shocks, a fire, or damages to the unit. This unit has hot and arcing or sparking parts inside. It is not designed to be used or stored in wet areas or areas containing flammable liquids, combustible materials, or corrosive, abrasive, chemical, explosive, and flammable substances such as but not limited to, gasoline, paint, chlorine, sawdust, and cleaning products.
Some areas are dustier than others. Thus, it is the user’s responsibility to evaluate if the unit must be cleaned based on the amount of dirt accumulated on and inside air vents. Accumulated dirt can lead to a component malfunction or give a yellowish colour to unit. Failure to install and maintain unit in accordance with these instructions poses a fire hasard.
Thermal protection activation indicates that the unit has been subjected to abnormal operating conditions. If the thermal protection remains activated or activates and deactivates repeatedly, it is recommended that a qualified electrician or a certified repair centre examine the unit in order to make sure it is not damaged. (Refer to the limited warranty)

If the unit is damaged or defective, cut off power supply at circuit breaker and call a certified repair centre. (Refer to the limited warranty)

Note: When a part of the product specification must be changed to improve operability or other functions, priority is given to the product specification itself. In such instances, the instruction manual may not entirely match all the functions of the actual product. Therefore, the actual product and packaging, as well as the name and illustration, may differ from the manual.

INSTALLATION ****

For the best results, the following distances should be respected when installing these unit heaters :

• When using a wall-mounted thermostat, install the thermostat on an interior wall or beam, away from cold airflow, other internal heat sources or the hot air discharge coming directly from the actual unit heater itself. Make sure to insulate the thermostat when installed on a steel beam.
• These unit heaters are designed to be hung from overhead, with chain, cable, or rigid supports. (not included with heater)
• On top of 5 to 10 kW unit heaters, there is four (koe Ø1/2″) 13-thread mounting holes for threaded rods.
• On top of 15 to 60 kW unit heaters, there are four eyebolts for chain suspension.
• Several optional cone diffusers are offered.

See the optional components section to obtain a complete list of cone diffuser available for optional orders.

OPERATION

This heater must be controlled with a wall thermostat. (Thermostat not included with heater)

ELECTRICAL WIRING

All heaters are factory wired so only field supply wires 90°C and thermostat leads are brought to the heater. Connections are made to contactor or terminal block as shown on wiring diagram inside the powerbox cover. The ground fault protection connection must be made by connecting the green wire originating from the circuit breaker panel to the green screw situated inside the powerbox of the heater.

N.B.This product must be installed by a certified master electrician, in accordance with all local and national building codes.

MAINTENANCE  ****

The motor and element of this heater are protected against overheating by heat sensors called automatic thermal protections (cut-outs). If these thermal protectors are activated continuously, this would indicate that the heater may be defective and it should be verified immediately.
If the heater operates under normal circumstances, it is not necessary to grease the motor. All of the motors installed in this series of unit heaters have been permanently lubricated.

WARNING

• Cut off power supply before manipulating any internal wiring.
• Periodically remove dust and debris from elements and fan blade.
• Do not operate in environments where there are flammable materials.
• Unit heaters must be installed so that they are kept out of the reach of individuals.
