This series of portable ventilation blowers has been designed for industrial heavy duty
applications in confined space ventilation. These blowers are the primary tool for providing
fresh clean ventilation air to remote work locations. Each work environment should be
thoroughly evaluated by a competent person before selecting the proper blower for a par-
ticularapplication.
SAFETY PRECAUTIONS:
READ AND FOLLOW ALL INSTRUCTIONS
All ventilation procedures should comply with federal, state, and local regulations. Air quality
should be tested prior to ventilating a confined space. A purge chart is provided on the ventilation equip-
ment to help assist in estimating the approximate time needed to ventilate confined spaces. Air quality
should be tested continuously during confined space occupancy to ensure a stable atmosphere and worker
safety because atmospheric conditions can change rapidly. Additional procedures and recommendations
are available from federal, state, and local agencies. DO NOT operate these blower units with the
flange or grills removed. DO NOT USE STANDARD ELECTRIC, GASOLINE, OR PROPANE
BLOWERS IF VOLATILE OR EXPLOSIVE VAPORS ARE SUSPECTED!

STEP1)
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
quality of 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.

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.
STEP3)
Connectto120VAC, 15amp,60Hzdedicatedservice. All standard electricblowerslistedare
suppliedwithGFI plug(GroundFault Interrupters)perthe 1996NECcode 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
unitisnowoperational.

Todos los procedimientos de ventilación deberían cumplir con los reglamentos federales,
estatales y locales. La calidad del aire debería comprobarse previo a ventilar un espacio
limitado. Se suministra una tabla de purga con los equipos de ventilación para ayudar a estimar el
tiempo adecuado que se necesita para ventilar un espacio limitado. La calidad del aire se puede
comprobar continuamente mientras se ocupe el espacio limitado para asegurar una atmósfera
estable y seguridad del trabajador, ya que las condiciones atmosféricas pueden cambiar
rápidamente. Procedimientos y recomendaciones adicionales están disponibles de agencias
federales, estatales y locales. NO opere estas unidades de ventilación verticalmente o con la brida
o rejas retiradas. ¡NO USE SOPLADORES ESTÁNDARES ELÉCTRICAS, DE GASOLINA, O
