OPERATION
4. Turn on power and check operation by turning on the shower or other humidity source until the fan turns on.
5. Repeat above steps if necessary.
When the temperature changes, humidity sensor values will have deviation.
TIMER ADJUSTMENT
The humidity sensing fan has a "T" (means timer) that can be adjusted from 5 to 60 minutes (factory-set at about 20 min-
utes). This "T" controls the length of time that the fan remains ON after the sensor has stopped sensing a rise in humidity
and the humidity level is below the user-adjustable set-point. To adjust the "T":
1. Disconnect power at service entrance;
2. Through the grille, locate the slot marked "T";
3. Carefully rotate the "T" adjustment to desired setting (from 5 to 60 minutes).
4. Check operation by turning on a humidity source until the fan turns on.
5. Turn humidity source off and time the unit.
6. Repeat above steps if necessary.
PLAN THE INSTALLATION
1. Do not use in a cooking area.
2. Two ways to connect ductwork to a factory-shipped unit.
TYPES OF TYPICAL INSTALLATIONS
1. Housing mounted to I-joists (Start at "ASSEMBLY INSTRUCTIONS 1")
2. Housing mounted to joists (Start at "ASSEMBLY INSTRUCTIONS 1" )
3. Housing mounted to truss (Start at step "ASSEMBLY INSTRUCTIONS 2")
ASSEMBLY INSTRUCTIONS
1.MOUNT HOUSING TO JOIST OR I-JOIST.
Hold the housing so that it is in contact with the bottom of the joist.
Place the fan housing next to the ceiling joist. Using wood screws
attach the housing loosely to the ceiling joist through the keyholes
in the mounting tabs. Adjust the housing to be flush with th
finished ceiling. For the grille to fit properly, the housing's rim must
not extend beyond the finished ceiling surface. When the housing
is correctly adjusted, tighten the screws in the slots.
