IMPORTANT: READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING
TO INSTALL, OPERATE OR SERVICE THIS FAN.
FAILURE TO COMPLY WITH INSTRUCTIONS COULD RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
Proper installation is required to
achieve maximum efficiency. It is necessary to provide adequate ventilation
to meet minimum intake air requirements. This prevents pressure buildup,
which will reduce the fan's efficiency.
Inadequate intake air can also lead to
premature motor failure.
CAUTION - SAFETY RULES
WARNING: TO REDUCE THE RISK OF
FIRE, ELECTRIC SHOCK OR INJURY,
OBSERVE THE FOLLOWING:
• Use this unit only in the manner
intended by the manufacturer. If you
have questions, please contact manufacturer.
• Before servicing or cleaning unit,
switch power off at service panel and
tag service panel to prevent power
from being switched on accidentally.
• Installation and electrical wiring must
be done by qualified person(s) in
accordance with all applicable codes
and standards, including fire-rated
construction.
• Sufficient air is needed for proper
combustion and exhausting of gasses
through the flue (chimney) of fuelburning equipment to prevent backdrafting. Follow the heating equipment
manufacturer's guidelines, along with
safety standards such as those published by the National Fire Protection
Agency (NFPA), the American Society
for Heating, Refrigeration & Air
Conditioning Engineers (ASHRAE),
and your local code authorities.
• CAUTION Check for hidden electrical
wiring or utility lines before cutting or
drilling into a wall or ceiling.
• CAUTION For general ventilating only.
DO NOT use to exhaust hazardous or
explosive materials.
• Your GPX fan will operate only on 120
volt AC, 60Hz (cycle) current.
• A permanent, THREE-WIRE (ground-
ed) wiring must be used. DO NOT USE
AN EXTENSION CORD.
• To avoid risk of fire, electrical shock
and other injuries, switch power off
at service panel and tag prior to the
installation.
• Do not operate fan in areas where gas
or oil-fired equipment is in operation.
• Wear safety goggles when drilling,
hammering, or cutting materials.
OPERATING YOUR FAN
IMPORTANT Do not operate your fan
without first providing adequate ventilation (such as a door or window) to
