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.
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.

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). Use this heater only as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury to persons. Do not use outdoors.

WARNING
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 odors 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 a few minutes before handling (it will stay warm for some time after shut- down). Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended.
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 (with objects or other items). You risk damaging the heater and the obstruction could lead to electric shock or 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 damage 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 color to the unit. Failure to install and maintain the unit in accordance with these instructions poses a fire hazard.
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 center examine the unit in order to make sure it is not damaged. (Refer to the limited warranty)
Before unplugging the unit, all controls must be in the “OFF” position and the current from the main breaker panel should be cut. (The general switch may be used also if included.)
If the unit is damaged or defective, discontinue use, cut off the power supply at the circuit breaker, and contact a certified electrician or certified repair center. (Refer to the limited warranty)

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.
