Place fan in a clean fresh air environment. Note: Inspect fan for damaged or worn parts. Inspect all ducting and couplings
for possible air leaks prior to fan operation.
Note: Air quality of the confined space should be tested prior to ventilation. If air quality of the confined space is unaccept
-
able, consult a trained professional.
SteP 3)
Install duct cuff to exhaust flange and tighten cinch strap. Keep bends and kinks in ducting to a minimum to maximize air
flow.
note:
The use of conductive ducting is recommended when operating in potentially explosive environments. Assure that
the fan is properly grounded before operating and the ground wire in the conductive ducting is attached to the fan and
Saddle Vent®, if used.
cAUtion
If explosive or volatile vapors are suspected or present, test the fan
for proper grounding using an ohm meter. All static electricity must
be removed from the fan and attached ducting prior to energizing the
fan. Conductive ducting should be tested semi-annually to assure
resistance (ohms) does not exceed 750k. If sufficient resistance is
not achieved, the duct should be removed from service.
SteP 4)
The “ON/OFF” switch is integrated in the motor. Pull the “ON/OFF” switch knob outward to turn the fan “ON”. The unit is
now operational. To turn the fan “OFF,” push the switch knob in toward the fan housing.

Excessive vibration
Air intake blocked
Turn fan off and clear debris from intake.
Possible internal damage
Turn off and inspect fan blades, shaft, and housing
for debris, damage, and loose screws.
Note: Never run fan for extended periods without
installing duct on the exhaust fl ange.
Possible external damage
Turn fan off and inspect for loose guards,
broken welds, etc.
Circuit breaker trips
Voltage output insuffi cient
Test outlet with volt meter.

load in motor trips
Extension cord is not of suffi cient
gauge
Eliminate extension cord and restart or
obtain extension cord of suffi cient gauge
SteP 1)
Explosion-proof models should be fitted with an ATEX/IECEx approved explosion-proof plug (Killark P/N ELAP15232) to
meet hazardous locations specifications. The plug should not be disconnected or connected in a hazardous environment.
