C. Switch on after finishing all wiring construction and re-checking.
Pay attention to the following points:
1. The heat pump must be installed OUTSIDE in a well ventilated area to avoid air
recirculation, or in a place with adequate room for both installation and
maintenance. Please refer to the following illustration for side fan models (FI500-
FI650-FI900).
2. For top fan models (FI1100-FI1400), clearance above the unit should be 8'
unobstructed and 20'' around.
A minimum of 20'' of clearance from walls, shrubbery, equipment, etc. is required around the entire
pump circumference. This allows for ample air intake. No less than 8' clearance on the air outlet
is required to prevent recirculation of air. We recommend to not place the unit underneath eaves,
decks, or porches, as this causes recirculation of discharged air, or the efficiency of the heater
will be reduced or even stopped.
The unit shouldn't be installed in a confined space or an area with poor ventilation
