Pre-Installation

PLANNING FOR SUCCESSFUL INSTALLATION
When installing the ventilation fan in a new construction site, install the main body of the fan and duct work during the rough-in construction of the building. The grille should be installed after the finished ceiling is in place.
When installing in existing construction, use the dimensions on page 7 to determine the required hole size for the ceiling. Grille edges should overlap finished ceiling.

IMPORTANT The ducting from this fan to the outside of the building has a strong effect one the airflow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.

INSTALLATION OPTIONS
We recommend installing the ventilation fan by securing the main body of the fan against one ceiling joist and using the hanger bars as necessary for support of the adjoining joist. There are multiple installation configurations possible for this ventilation fan. Not all configurations are shown. If your installation requires a variation other than those shown, consult with a licensed contractor to determine the best installation for your project. If you are replacing an existing fan, ensure that the new grille will adequately cover the existing opening.

Humidity Sensor Operation (Humidity Sensing Models Only)

The humidity sensing fan is equipped with a humidity sensor that can turn on the fan automatically when the humidity level in your bathroom rises above your setting point (40 ~ 80 RH % continuously adjustable).

CAUTION: Humidity tolerance is about ±10%. Long-time operation will influence the detecting precision as dust accumulates. The humidity switch may need to be adjusted.

Humidity sensing mode

1. Pre-set a trigger point from 40 ~ 80 RH %.
2. When you finish the wiring, the fan will be on the humidity sensing mode. The fan will automatically run when the humidity level in the room is above your setting point. If the humidity level drops below your setting point, the fan will stop automatically.

Full speed mode

1. Flip the ON/OFF switch to the “ON” position.
2. The fan will be set to the full speed mode. The fan will run continuously regardless of the humidity level.
3. Flip the ON/OFF switch to the “OFF” position, the fan will be set back to the humidity sensing mode.
