1) Place fan in a clean, fresh air environment.
2) 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.
3) Inspect fan for damaged or worn parts, and inspect ducting for air leaks prior to fan operation.
4) Install duct cuff to exhaust flange and secure. Keep bends and kinks in ducting to a minimum to maximimize
air flow. If canister model is used, secure canister with connect straps, open lid and pull out ducting. Inspect
for air leaks.
Note:
Maximum recommended duct hose length is 25 ft.
5) Set fan upwind from the work location and a minimum of 5 ft. from the manhole opening.
6) Connect fan to power source.
DC versions require 12 VDC. Attach the red connector to the positive (+) terminal and the black conector to
the negative (-) terminal. This unit must be run in the positive pressure mode as this model is not approved
for extracting (sucking) air. DO NOT REVERSE WIRING.
WArNiNG:
Vehicle electrical systems must be able to handle 15 amp service or electrical damage may occur.
AC versions require 115 VAC/60Hz (SVF-8AC), 15 amp service or 220 VAC/50Hz (SVF-8AC50).
Note:
If an extension cord is required, the minimum recommended size is 14 AWG up to
25 ft. For further information refer to the National Electric Code Tables, Article 400.
7) Push ON/OFF switch to “I” position.
