2 Safety
2.1 Safety definitions
Warnings, cautions and notes are used to point out specially
important parts of the manual.
Warning
If you do not obey these instructions, there
is a risk of death or injury.
Caution
If you do not obey these instructions, there
is a risk of damage to the product, other
materials or the adjacent area.
Note:
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.
• 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.
• Do not place the switch where it can be touched from a
shower or tub.
Caution
To decrease the risk of product malfunction
or damage to the product or surrounding
finishes and walls, read and obey the fol-
lowing caution instructions before you do
work on the product:
• When cutting or drilling into walls or ceilings, watch for elec-
trical wiring and other hidden utilities to prevent damage.
2
• Ducted exhaust fans must always be released to the
outdoors
• Install screen guards within 7 feet (2.1 meters) from the
working area of the product.
• Do not release air into spaces within walls or into attics,
crawl spaces, or garages.
• Do a check of the voltage at the fan to see if it corresponds
to the motor name plate.
Ducting has a strong effect on the air flow, noise and energy
use of the fan. Use the shortest, straightest duct routing possi-
ble 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
• Approved protective shoes
• Approved work clothing
