Installation of Ceiling Grille Housing With or Without Light
1. Plan Location of Inlet Grilles.
Based on the bathroom layout and fixtures, plan the location of the ceiling
grilles for the most effective ventilation.
2. Securing the Housing to the Ceiling Joists.
NEW CONSTRUCTION
Mount housing directly to the ceiling joist using screws and keyhole slots.
Locator tabs on housing should be flush with the bottom edge of the ceiling
joist for correct positioning of the unit once drywall is installed.
(Figure 1)
OR
Use the hanger bars to suspend the housing between ceiling joists. For
correct positioning, hanger bars should be positioned
edge of joist on models with 6" duct connection. Hanger bars on units with
6" duct connection span ceiling joists up to 16" on center.
Note: If drywall or ceiling material is thicker than
be removed to allow the grille collar to be flush with the finished ceiling
material. When ceiling drywall is being installed, cut hole for ceiling grille.
EXISTING CONSTRUCTION OR WHEN DRYWALL IS IN PLACE.
Cut a 6" round hole for the ceiling grille only and install the housing from
the attic. (Figure 3)
Place the housing against the ceiling joist using the locator tabs to
determine the correct position (Figure 1) or align it using the hanger bars.
(Figure 2).
Punch out the keyhole knockouts (if using).
3.
Connect the Fan to the Ceiling Grille Housing(s).
appropriate diameter duct from the fan to the ceiling grille housing.
(Insulated flexible duct is recommended for all Fantech bathroom exhaust
applications for quieter operation.) For dual grille models, install duct
between fan and wye adapter* (included). Then, attach duct to each leg of
the wye and to each ceiling grille housing. Secure duct in place and seal.
If using insulated flexible duct, seal the inner liner to the duct connector
then seal the outer shell over the top of the inner liner. Do not leave the
insulation material exposed.
Repeat steps 1 through 3 for each additional ceiling grille housing being installed.
*For most efficient operation wye adapter should be positioned at least the
equivalent of three duct diameters away from the fan inlet.
Troubleshooting
If fan fails to operate, please check the following:
1. Consult wiring diagrams (above) to ensure proper connection.
2. Check motor lead wiring, capacitor leads and incoming supply leads to
ensure definite contact.
3. If possible, use a meter to test for continuity across the fan motor
leads. In order to do this, the capacitor must be disconnected (do not
test the capacitor - it will not meter continuity). If motor leads show
continuity, consult factory for a replacement capacitor.
Maintenance Instructions
Since fan bearings are sealed and provided with an internal lubricating
material, no additional lubrication is necessary.
