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 fuel-burning 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 wir-
ing 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 (grounded)
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 provide the proper
inlet airflow.
WARNING BEFORE PROCEEDING WITH
THE INSTALLATION, SWITCH POWER OFF
AT SERVICE PANEL. The fan requires a 120volt AC power source with at least 5-amp
capacity (10-amp for 24" and 30" GPX). All
electrical work must be done in accordance
with local building codes, using approved
material. Follow the wiring diagram shown
on next page.
