INSTALLATION OF HOUSING (Refer to Figure 2)
PQ 50 Rough Opening: 17.8cm (7”) l * 17.8cm (7”) w
Housing Size: 17cm (6 11/16”) l * 17cm (6 11/16”) w
* 18.5cm (7 9/32”) h
1. Remove the louver from the unit before the mounting
2. Install sliding hanger bars onto the fan housing by inserting the bars into the hanger bar support guide rail.
3. Loosely attach one end of a hanger bar to joist by inserting a screw through the eyelet at the end of the bar into the woode
n joist.
4. Attach the second hanger bar to the same joist.
5. Level the fan housing and attach the third and fourth hanger bar ends to the next joist. Adjust and tighten the screws.
6. For the louver to fit properly, the flange of the housing must be leveled to the soffit level of the ceiling.
INSTALLATION OF LOUVER (Refer to Figure 2)
The louver can be installed when the finished ceiling has been completed, Place the louver’s
torsion spring mounting clips into the slot holes on the both sides of the fan unit and press it
closed.
WIRING (Refer to Figure 3)
IMPORTANT: The power to your GNN Air ventilation fan must disconnected before
installation begins.
IMPORTANT: Be certain all wiring complies with local codes and that the fan unit is
properly ground.
1. Run power leads from the wall switch or time switch to the unit.
2. Using the approved wire connectors, connect supply wires to fan wires: black
(or brown) to black (or brown) and white (or blue) to white (or blue). Connected
ground wire (green or bare) to the ground connection in the fan’s junction box.
DUCTING (Refer to Figure 4)
1. Run 4” round duct from the air discharge opening to the outside of the building.
2. Sheet metal duct is recommended.
Properly insulate the area around the fan to minimize building heat loss and gain. Loose fill
or batt insulation can be placed over the fan housing in the attic.
MAINTENANCE (Refer to Figure 4)
WARNING: Disconnect the power source before servicing.
NOTE: Never use petrol, benzene, thinner or any other chemicals for cleaning the ventilating fan. Do not allow water get into motor. Do
not immerse plastic parts in hot water over 60 C.
Routine maintenance must be done every year.
1. Remove the louver from the fan.
