Operation
Installing AFD on the Triad Thruster Fan
1. Remove all cords and ducting from fan's top intake
nozzle.
2. Check all seals and gaskets for any damage. If
required, only replace with Prochem factory parts.
3. Lift the AFD over the Triad fan.
4. Catch the fan's top intake flange with the AFD's 2
housing retention tabs, and let it rest on top of the
fan.
5. Tighten the AFD's securing knob until the knob's
ball is tightly under the fan's intake flange.
NOTE: Attaching duct to the AFD intake is the same
as attaching it to the Triad's intake.
NOTE: Cords can be stored around the intake nozzle
of the AFD, like the Triad. Leave enough slack so the
upper housing can be removed easily to change the
filters.
6. Switch Triad air mover to the 'on' position.
7. Remove the 'Containment Plug' from the inlet of
the AFD.
8. Adjust the 'Restrictor Plate Assembly' if operating
the AFD in a negative air ducting situation. If
operating in an open room or if controlling airflow is
not desired remove the 'Restrictor Plate Assembly'.
9. Prior to moving or transporting the AFD the
containment plug should be re-installed. To do this,
while the air mover is still operating install plug into
inlet neck of the AFD. The suction of the air mover
will pull the plug into the neck. This will seal the
collected contaminants within the AFD during
transit or relocation.
Back Draft Prevention
Exhausting too much air from a space with Open
Combustion Devices ( e.g. furnace, fireplace or
water heater) can cause those devices to back draft.
This can contaminate the space with potentially
fatal gases.
Use the fan as a filtering unit only. Exhausting no air
from the space and thus causing no negative pressure
or back drafting.
OR
Exhaust a very limited amount of air, which does not
cause back drafting.
The intake of the AFD has a rotating air flow limiting
device.
OR
Direct one or more outlet ducts from the fan to the room
with combustion devices. This will positively pressurize
the room, thus preventing back drafting.
When exhausting air from a space, always check
Combustion Devices with the fan running to
guarantee that back draft prevention measures are
working.
