Fantech Ventilation Hood PBW100H Manual De Usuario

1. Once you have chosen the location where you wish to mount the fan,

cut a 4 ³⁄₈" diameter hole in the exterior of the wall. Prepare a piece
of rigid duct (purchase separately) approximately 2" longer than the
wall thickness. This will be used as a collar extension placed through
the wall.

2. Take off the fan discharge cover by removing the four screws. Center

the fan in the hole that was cut into the wall. Mark the locations of
the mounting holes and electrical knockout. Drill a hole for the
electrical that is ¹⁄₈" larger than the conduit being used. A 1"
electrical service opening is provided on the fan backplate.

NOTE: When mounting the fan to a masonry wall, drill ⁷⁄₃₂" holes for
the four anchors and mounting screws (provided). Anchors should be
flush with the edge of the holes. For mounting to wood surfaces use
wood screws (purchased separately).

3. Bring your electrical supply through the wall. Attach the fan collar to

the extension collar using duct tape. Be sure this connection is as
airtight as possible to prevent leakage. Apply polyurethane caulk to
the exterior of fan housing backplate, leaving bottom uncaulked for
drainage. This will ensure an airtight/waterproof connection between
the fan and wall.

NOTE: If installing on lapped siding it may be necessary to use a
mounting frame made from 1x1 board to insure a flush fit.

4. Mount the fan to the wall. Replace the discharge cover. Connect your

ducting to the extension collar using plastic ties or duct tape
(purchased separately). 

FINAL INSTALLATION NOTE: If fan location
is not protected by an eve, a standard
flashing should be installed.  Seal against
the wall and upper edge of the fan
discharge cover to prevent rain water
from entering fan housing.

Fantech strongly recommends the use of flexible insulated duct where
ducting passes through unconditioned space or where noise is a factor.
Check local code requirements before installing. Failure to use insulated
flexible duct could result in excessive condensation buildup within the
duct, and undesirable sound levels within the room. 

A minimum of 8' of insulated flexible duct is recommended between 
the fan and any inlet grille. Duct should be stretched as tight and straight 
as possible. Failure to do so could result in dramatic loss of system 
performance. Connect flex duct to the fan with plastic zip ties or duct tape.
Connections should be airtight as possible for maximize performance.

1.

Remove the screws securing the terminal box cover located on the
fan motor mounting bracket. All fan motor and capacitor connections
are pre-wired to an electrical terminal strip. A 

3

8

" romex type cable

restraint connector will be needed to secure the wiring through the
knockout on the side of the terminal box. 

2. Bring incoming electrical service through the romex connector and the

fan electrical service opening. Be sure to place the connector nut over
the wiring coming into the terminal box. There are two open ports on
the terminal strip. Using a small regular screwdriver, tighten the neutral
(white) wire of the incoming supply under the open terminal strip port
labeled “N”. Tighten the line (black) wire of the incoming supply under
the open terminal strip port labeled “L” to the ground connection on the
terminal block.

3. Secure the romex connector. Secure the incoming supply with the

romex connector. Place the capacitor back into the terminal box.
Replace the fan terminal box cover.

All fan motor and capacitor connections have been pre-wired from
the factory.  No additional fan wiring is necessary.

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 insure 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.

Since fan bearings are sealed and provided with an internal lubricating
material, no additional lubrication is necessary.

As with any exhaust system, your exhaust fan should be located a
minimum of 6 feet horizontally and 8 feet vertically from any fresh air
intakes to prevent re-entrainment of exhaust air streams. For example
HVAC systems, heat recovery systems, and windows would all be
considered fresh air intakes.

When planning your fan placement keep in mind that you will need to 
be able to run your duct work from the exterior fan to the bathroom
inlet. Considering access for the duct run before hand will make
installation easier.
