Model Svb-E8Exp - AIR SYSTEMS INTERNATIONAL SVB-E8 Manuel D'utilisation

GENERAL SETUP & OPERATION, EXPLOSION-PROOF ELECTRIC BLOWER

MODEL SVB-E8EXP

STEP 1)
Place blower in a clean fresh air environment. Set blower a minimum of 5 ft. from the
manhole opening. Note: Inspect blower for damaged or worn parts. Inspect all ducting
and couplings for possible air leaks prior to blower operation.
Air quality of the confined space should be tested prior to ventilation. If air quality of the
confined space is unacceptable, consult a trained professional.
STEP 2)
Install duct cuff to exhaust flange and tighten cinch strap. Keep bends and kinks in ducting
to a minimum to maximize air flow. THE USE OF CONDUCTIVE DUCTING IS REC-
OMMENDED WHEN OPERATING IN POTENTIALLY EXPLOSIVE ENVIRON-
MENTS.
STEP 3)
Explosion-proof models should be fitted with an approved explosion-proof plug to meet Class I, Div. I, Groups C and D,
Class II, Div. I, Groups E, F, G specifications. The plug should not be disconnected or connected in an explosive environ-
ment when the blower is energized.
STEP 4) Switch the explosion-proof "on/off" switch to the "on" position. The unit is now operational.
SHUTDOWN
• Insure that all workers are removed from the confined space site.
• Shut off blower and remove all ducting.
MAINTENANCE
• Keep blower motor dry and free from contaminants and dust.
• Check periodically to ensure moving parts are free from obstructions.
