Air Ducting
If area to be filtered is difficult to access, congested or the air scrubber cannot be located within, air can be ducted to the
unit’s inlet. A round 16” diameter flexible duct can be attached to the unit inlet. It connects by placing the wire in the
duct over the duct collar lip at one location and working over it over the lip gradually.
Outlet Ducting
A detachable trapezoid shaped exhaust ring is supplied that will allow 10” round lay-flat plastic duct to be attached to
the exhaust outlet. To attach ducting to the collar, remove the ring from the unit by pressing release tab at the top of the
grill. Put the plastic duct end through the inside of the ring. Roll the duct end outward so that it over-laps the outside of
the ring. Clip the ring back onto the exhaust grill.
Negative Air Ducting
HEPAPro AS800 can be used to filter and exhaust air from an enclosed containment area. When exhausting air outside
the containment area, the air inside the containment area must be under slight negative pressure. This will help prevent
airborne particles from leaving the containment area, because negative pressure will draw air in through openings in
the space’s exterior surfaces.
Ducting
Power/Speed Control
The power/speed switch is located on the control panel. It powers the motor and impeller fan. Occasionally the impeller fan may
not start on the low speed setting. If this occurs, rotate the speed control to high speed until the impeller fan starts, then adjust it
to a lower speed.
Resettable Circuit Breaker:
The 12 AMP thermal, resettable circuit breaker protects the unit and devices connected to its duplex GFCI outlet. The circuit break
-
er is designed to sense the total current draw through the circuit. The circuit breaker “trips” when more than 12 amps of electrical
current are drawn through the device’s power cord. Should an overload condition occur, the on-board circuit breaker prevents a
trip to a remote power junction box. IMPORTANT: Total amperage of the HEPAPro AS800, plus all devices plugged into the recep
-
tacle must not exceed 12 amps. The circuit breaker will not allow for loads in excess of 12 amps.
GFCI Protection and the On-Board Outlet:
The standard AC voltage outlet with GFCI (Ground Fault Circuit Interrupter) protects the operator in wet applications. GFCI devices
trip when a fault to electrical “ground” is sensed. It is recommended to check the GFCI protection prior to operation. To check,
push the “TEST” button located on the GFCI duplex outlet. If operating properly the “RESET” button on the GFCI outlet will pop
out. A tripped GFCI is indicated by a small LED. The device can only be “RESET” when the unit is connected to a wall outlet provid
-
ing standard voltage. This duplex AC outlet allows the inter-connection of other AC powered devices. The sum total amperage of
all devices plugged into the receptacle must not exceed 10 amps.
