INSTALLATION INSTRUCTIONS

ATTENTION:

For bathroom use, the heater must be installed so that switches and other controls cannot be touched by anyone in the bath or shower.
This product is not recommended with the ground fault circuit interrupter (GFCI). The humidity in the air can generate a leakage current higher than the limit of the GFCI which will cause the product to stop.

Provide an opening as shown on the drawing, a minimum of 3 in. (76 mm) deep.
Remove the appropriate knock-out from the recess box for the electrical supply. The heater junction box volume is 35 in.3 (576 cm3).
Install the heater or the recess box and be sure that the heater is attached firmly with the provided screws. Make sure that the edge on each side of the recess box leans on the gypsum panel and not on the structural parts of the ceiling. See the marking on the sides of the recess box.
- IMPORTANT: If the recess box is pre-installed, insert the keyholes of the venturi on the screws of the recess box and tighten the 4 screws to prevent vibration.
Connect the heater leads to the supply leads according to the wiring diagram of these instructions by local and national codes.
Install the grille using the provided screws. Make sure that the fan blade is free to rotate and the heater assembly is free of foreign objects and/or matter. Make sure that the solid panel of the grille covers the supply connection box.
