GENERAL SETUP & OPERATION, ELECTRIC BLOWER SERIES
MODELS SVB-E8, SVB-E8-2, & SVB-E8EC
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.
Note: Air quality of the confined space should be tested prior to ventilation. If air
qualityof the confined space is unacceptable, consult a trained professional.
(Model SVB-E8EC blower does not come standard with an intake flange. Intake flange
can be purchased as an option from Air Systems Repair Service Department. Order part
no. METL196O.
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.
STEP 3)
Connect to 120 VAC, 15 amp, 60Hz dedicated service. All standard electric blowers listed are
supplied with GFI plug (Ground Fault Interrupters) per the 1996 NEC code requirement: Section
305-6.
Note: If an extension cord is required, the minimum recommended size is 12 AWG
(Maximum 100 ft.). For further information, refer to the National Electric Code Tables,
Article 400. (The use of generators are not recommended unless they are of sufficient
output capacity. Some generator's output current will not allow the use of GFI plugs. A
standard 3-prong plug would need to be installed instead of the GFI recepticle).
STEP 4) Push "on/off" (reset) switch, located on the GFI unit, 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.
