FAN INSTALLATION
Disconnect and lock out power supply before performing any installation work.
Working on or near energized equipment could result in death or serious injury.
STEP 1. FAN LOCATION
For optimum performance, the AXC in-line duct fan should be mounted near the termination of
the duct, close to an outside vent. Allow sufficient access to the fan for recommended maintenance.
STEP 2. INSTALL FAN
Attach mounting brackets to the fan housing as shown in Figure 1a or
Figure 1b. Please note the airflow direction arrow located on the box
cover. Secure the fan to a support at the selected location. The fan may be
mounted in any position; however, vertical orientation is recommended
to reduce condensation build-up in the fan. The terminal box should be
positioned for easy access.
STEP 3. EXHAUST GRILLE LOCATION
Select a location that will facilitate the rapid collection and dissipation
of bathroom air. For larger bathrooms, it is recommended that two exhaust
grilles be installed: one near the shower, and the other above the toilet. If
two grilles are used, both exhaust ducts should be directed to a Y-fitting
(included in all DX Kits), resulting in a single duct run to the fan.
NOTE:
It is recommended running the fan run for 15-20 minutes after a shower to remove excess
humidity, and minimize mold and moisture damage.
STEP 4. INSTALL EXHAUST GRILLE
Place the exhaust grille collar(s) in the selected location and trace around the inside of the collar.
Cut a circular hole along the traced outline. Mount the collar flange flush with the ceiling and
secure by screwing from the front and sliding collar clamp over the rear of the collar. Once the
collar is securely mounted, snap the grille into place. Using an adjustable grille, (capable of 100%
shut off ), allows for airflow to be regulated as desired.
STEP 5. CONNECT DUCT
Rigid duct is recommended to optimize fan performance. If using flex duct, it should be stretched
as smooth as possible. Connect duct to the inlet and outlet ends of the fan housing by means of
mounting clamps or duct tape, and seal to prevent air leakage and loss of fan performance. Secure
duct to collar by means of the plastic clamp supplied with the collar. Alternately, metal gear clamps
or duct/foil tape may be used.
NOTE:
For duct runs in unheated spaces, insulated duct is recommended to reduce the effects of
condensation. To minimize condensation at the exhaust grille, the duct should run horizontally
before connecting to the grille collar.
STEP 6. CONNECT WIRING
Refer to wiring diagram below. Reattach all electrical box covers before applying power.
