STELPRO RWF Series Pulsair Wall Fan Heater Owner’s Manual

STELPRO RWF Series Pulsair Wall Fan Heater

IMPORTANT INSTRUCTIONS

Before installing and using this product, you must read and understand these instructions and keep them for future reference. If the installer and the user do not follow these instructions, the manufacturer cannot be held liable in any way and the warranty will be null and void.
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.
The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries and potentially fatal electric shocks.
Protect the heating unit with the appropriate circuit breaker or fuse, in ac- cordance with the nameplate.
Make sure the line voltage (volts) is consistent with that indicated on the unit’s nameplate.
This unit must be grounded.
Switch off the power at the circuit breaker or fuse before installing, repair- ing and cleaning the unit.

INTENDED USE
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 per ft3 (0.03 m3).
This corresponds to 10 W per ft2 (0.09 m²) based on a standard ceiling height of 8 ft (2.44 m). The recommended capacity is usually sufficient for normal heating needs. Please note that the insulation quality of walls and windows are some of the factors that influence heat losses, which modify the required capacity to heat a room. If needed, speak with a specialist
(industrial and commercial buildings) who will be able to calculate these heat losses and optimize the required capacity or consult the “Calculation Tools/Heating Calculator” section of the Stelpro Design website. To heat a large room and increase its comfort, you should install multiple units instead of one, for instance, 2 x 1000 W rather than 1 x 2000 W.
If the unit capacity is insufficient for the size of the room, it will be in opera-tion continuously, and may become defective earlier and turn yellow.

POSITION

• Do not install the unit where objects or pieces of furniture could be heat damaged.
• Respectez les distances et les positions mentionnées dans la section d’installation de ce guide.
• If the installer or the 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., splashes from a sink or shower). 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 mounting the unit, ensure that the anchorage can support the total weight of the unit plus the weight of the mounting brackets.
• When cutting or drilling a wall to install the unit, be careful not to damage hidden electrical wiring and other utilities.
• Do not install this product on walls made of synthetic materials such as, but not limited to, carpet and upholstery.

RISK OF FIRE, ELECTRIC SHOCK,

BODILY INJURY AND DAMAGE

When starting up the unit for the first time or after a long period, it is nor-mal that it produces some temporary odours and a thin 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. The unit must cool down for few minutes since it will stay warm for some time after shut down.
Leave at least 8 inches (20.3 cm) of free space between the unit and any adjacent surfaces (walls and floors). Moreover, do not allow objects or furniture such as, but not limited to, blankets, towels, bedding, laundry baskets, clothing, papers, etc. to come in contact with the unit and keep them at least 12 inches (30.5 cm) away from the unit, as they may ignite more easily than adjacent surfaces. Also, some materials are more sensi-tive to heat than others, so make sure that the materials near your unit can withstand the heat it gives off.
Do not install on a wall behind a door.
To prevent a possible fire, do not block air intakes or exhaust in any matter.
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.
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, paint, gasoline, chlorine, sawdust and cleaning products.

MAINTENANCE

Some areas are dustier than others. Thus, it is the user’s res ponsibility to evaluate if the unit must be cleaned based on the amount of dirt accumu-lated on and inside air vents. Accumulated dirt can lead to a component malfunction or give a yellowish colour to the unit. Failure to install and maintain the 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 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, discontinue use, cut off power supply at circuit breaker or fuse and have it repaired at a certified repair centre.
Make sure that the electrical connections are secure and that they have been made properly. Pull on each wire to ensure that there is no slack in the connector or terminal block. Failure to do so could result in a fire.
If adding an option to the unit, make sure it is approved by Stelpro. This will ensure that it has been tested in accordance with the established safety rules and that proper installation has been provided for it in the unit.
