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

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). The recommended capacity is usually sufcient
for normal heating needs. Please note that the insulation quality of walls and windows are some of the factors that inuence heat losses, which modify the
required capacity to heat a room. If needed, refer to a specialist (industrial and commercial buildings) who will be able to calculate these heat losses and
optimize the required capacity or consult the “Online heating calculation” section of the Stelpro Design Web site (residential buildings). To heat a large room
and to increase your comfort, it is recommended to install several units instead of one. For example, 2 X 1000 W rather than 1 X 2000 W.
If the unit capacity is insufcient for the size of the room, it will be in operation continuously, and may become defective earlier and turn yellow.
