Operations
For Asbestos and mold abatement, the machine must be operated with a HEPA filter in place. Also, it is recommended to use the
primary/secondary filer and replace it frequently to extend the life of the HEPA.
Speed Control
The OA2000C has two speed settings: Low and High. These will operate the machine at 900CFM and 1600 CFM respectively.
The OA2000V has a variable speed setting, which operates the machine between 400 and 1600 CFM. The unit can also be fixed
at a high speed using the HIGH/VARIABLE speed selector switch.
Start the Machine
For the OA2000C, simply turn the switch to HIGH or LOW speed position.
For the OA2000V, to start the machine in high speed, set the rocker switch HIGH/VARIABLE speed to the HIGH position. In this
position the SPEED CONTROL is disabled. To start the machine in VARIABLE SPEED, set the rocker switch to the VARIABLE
SPEED position and rotate the SPEED CONTROL knob clockwise to obtain the desired airflow.
As the filters fill with dust, the efficiency of the filters is maintained, but the airflow will decrease, and the vacuum reading will
increase. Change the primary/secondary filter frequently to protect the HEPA and to get more air flow. When amber indicator
light comes on, the REPALCE FILTER indicating light will turn on and the HEPA filter will have to be replaced to increase the
air flow. Accessories such as an optional intake manifold can be used on the suction side of the unit providing
12”
connection
for the flex duct.
The discharge side of the unit has a 12” diameter ring for a flex duct.
