Information that is necessary in a given situation.
2.2 Safety Instructions
Warning
This product is intended for general ventila-
tion use only. If you have questions, contact
Fantech. To decrease the risk of fire, elec-
tric shock, or injury, read and obey the fol-
lowing warning instructions before you do
work on the product:
• The ventilation contractor and the operator are responsible
for correctly installing the product.
• When installing the product, obey all applicable local condi-
tions and laws, and fire-rated construction codes and
standards.
• Because the product has rotating parts, exercise safety pre-
cautions when installing, operating, and maintaining the
product.
• Before installing, servicing, or cleaning, set the product’s
electrical power supply source in the OFF position, and lock
the service disconnecting means. If the service disconnect-
ing means cannot be locked, tightly attach a large warning
device to the service panel.
• To prevent the product from backdrafting, obey the heating
equipment manufacturer’s guidelines and safety standards
such as those published by the National Fire Protection As-
sociation (NFPA), the American Society for Heating, Refrig-
eration & Air Conditioning Engineers (ASHRAE), and the
local code authorities.
• When cutting or drilling into walls or ceilings, watch for elec-
trical wiring and other hidden utilities to prevent damage.
• Ducted exhaust fans must always be released to the
outdoors
• When installing the product over a tub or shower, identify as
appropriate for the application and connect to a GFCI
(Ground Fault Circuit Interrupter) – protected branch circuit
(ceiling installation only).
• Make sure the product is correctly grounded.
• Never place a switch where it can be reached from a tub or
shower.
• Do not block the air intakes or exhaust.
• Do not mount this product in an outdoor location.
• Install the product at least 7 feet (2.1 meters) above the floor.
• Do not start and stop the product quickly.
• Do not clean the product with chemicals that can cause cor-
rosion or water more than 60° Celsius (140° Fahrenheit).
• Do not let unwanted objects enter the product.
• Do not use this product to remove hazardous or explosive
material and vapours.
• Do not mount this product vertically.
• This product is designed for installation in ceilings up to a
12/12 pitch (45 degree angle)
• Do not mount this product in kitchens.
• Do not release air into spaces within walls or into attics,
crawl spaces, or garages.
• Do not install this product in a ceiling with a thermal insula-
tion value more than R40.
Note:
Ducting has a strong effect on the air flow, noise and energy
use of the fan. Use the shortest, straightest duct routing pos-
sible 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 air
flow.
2.3 Personal protective equipment
Use personal protective equipment during all work on the
product.
• Approved eye protection
• Approved protective helmet
• Approved hearing protection
• Approved protective gloves

3.4 To Attach the Duct
Caution
To keep pressure losses to a minimum, and
promote sufficient airflow, observe the
following:
• Where possible, use short and straight
duct run lengths.
• Do not install the product with existing
duct.
• Do not install smaller than recommen-
ded duct on the product.
Note:
For quiet operation, and to maximize performance, Fantech
recommends the following:
• Use insulated flexible duct for quiet operation
• If rigid duct is used, use 1–3 feet (0.3–0.91 meters) of in-
sulated flexible duct.
• Insulate the duct to minimize energy losses.
• If installing in an unconditioned space, attach insulation to
the product to prevent condensation
1Using duct tape, attach the duct to the duct connector.
2Examine the duct around the duct connector to make sure
the seal is air tight.

3.5 To Manage the Duct Run
1Using duct tape, attach additional ducts to the product to
make sure air is released to the outdoors.
2Depending on the shortest & straightest direction to the
outdoors, place the duct run either through the roof or
through the wall.
3If the duct was installed through the roof, attach an applica-
ble roof cap to the end of the duct run.
4If the duct was installed through the wall, attach an applica-
ble wall cap to the end of the duct run.
5Place insulation around the product’s casing.
6With sealant, close all gaps between the framing and the
product’s casing.

3.6 To Mount the Light
Note:
Dimensions are given in inches (mm).
Note:
The lamp base can adjust up or down to move the lamp into
the casing.
1Measure a diameter of 6–1/2 inches (165mm) on the ceil-
ing, and make an applicable mark.
2Identify the marking and cut a hole with a diameter of 6–1/
2 inches (165mm) on the marking.
3With sealant, close any gap between the hole in the ceiling
and the product.
4Position the fluorescent lamp in the hole.
5Using the wing nut, attach the lamp inside of the lamp base.
6Once the lamp has been attached to the lamp base, close
the gap between the hanger bar flange and the ceiling with
caulk or another sealant to prevent air leakage.
