unit but is compact and easy to move and set up. The 2000C is used to create positive or negative pressure
at asbestos, lead and mold abatement projects, for collection of construction dust from cutting or grinding of
concrete, wood or plaster. The HEPA filter can also be replaced with an economical multi-pocket bag filter. Additional
accessories include intake manifold, flex ducting and quick clamps.

To create NEGATIVE PRESSURE inside the containment,
more air has to be exhausted out than leaks into the
containment. Place the machine inside the containment
and hook a flexible duct to the outlet ring of the
machine exhausting to outside the containment.
(See Above) All of the air being exhausted has been
treated by the HEPA filter so no contaminants are being
exhausted from the containment.

activated carbon web filter; VaporTrap V-bank filter (27 lbs of active carbon); HEPA filter 99.99% @ 0.3μ, Bag filter
housing (with one bag filter included)
Recessed Controls: speed switch - HIGH/OFF/LOW; amber change filter indicator light; red power indicator light

To create POSITIVE PRESSURE inside the containment,
more air has to be pumped in than leaks out of the
containment. Place the machine outside the containment
and hook a flexible duct to the outlet ring of the machine
ducting the exhaust into the containment. (See Above)

Receiving Instructions

Visually inspect the unit for damage. Remove the primary/secondary filter and ensure that the HEPA filter has not been
dislodged during shipping. The HEPA filter should be sitting on the filter guides and the filter tabs that hold the HEPA
filter in place should be tight.

If the filter is not seated correctly then remove the filter tabs, reposition the filter, and reinstall the filter tabs before
operation to ensure that there is no bypass around the filter. If the filter tabs are loose verify that the filter is in the
correct position and retighten the filter tab nuts.

Operation

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.

Start the machine

Place the switch in the HIGH or LOW position to turn the machine on. When filters are clean, the REPLACE FILTER
indicator light will be off. As the filters fill with dust the efficiency of the filters is maintained, but the air flow will
decrease and the differential pressure across the filter increases. Change the primary/secondary filter frequently to
protect the HEPA and to get more air flow. When the differential pressure reaches about 3.0” WC, the REPALCE FILTER
indicating light will turn on and the HEPA filter will have to be replaced to increase the air flow. Additional 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.

Maintenance

The blower and motor do not require any maintenance when the machine is operated with the HEPA filter in place.

Prefilter Replacement

The primary/secondary filter should be changed when the orange side shows it is loaded with dust. Changing the
filter can be done while the machine is running. Ensure that the orange side of the prefilter is facing the HEPA filter.

HEPA Filter Replacement

During your projects, your HEPA filter purifies the air and gradually becomes loaded
with sub-micron particulates. Even when the HEPA filter is fully loaded, the filter is still
removing particulates from the air at the rated efficiency yet at a reduced airflow. This
will affect the ability of the machine to provide positive or negative pressure within the
containment.

To replace the HEPA filter unplug the machine and remove the screen/manifold to
remove the prefilter. You will see 4 filter tabs holding the HEPA filter in place (see photo).

filter tab

Remove all 4 filter tab retaining nuts and remove the filter tabs and set aside. Slide the HEPA filter out along the
filter guides and remove it from the machine. ALWAYS TREAT THE USED HEPA FILTER AS HAZMAT AND PROCESS IT
ACCORDING TO YOUR ESTABLISHED HAZMAT PROCEDURES.

To replace the HEPA filter ensure that the gasket on the HEPA filter faces inwards toward the flange, slide the filter
in place along the filter guides and re-install the filter tabs and filter tab securing nuts. The nuts should initially be
tightened to where the stud is flush with the end of the nut. This will compress the gasket on the filter approximately 1/2
of the thickness. This allows for the filter to be reseated and tightened at a later time if necessary.

These tabs are secured with 1/4-20 Nylock nuts, which require a 7/16” wrench or socket.

Bag Filter Replacement

For the projects that do not require a HEPA filter, the economical bag filter can be used to control the dust at
construction sites. The bag filter housing can be installed in place of the HEPA filter. The Bag filter with a MERV 15 rating
and multi pocket configuration has a large dust holding capacity and require replacement when the airflow of the
machine drops below your required minimum flow. Typically bag filters do not require the use of prefilters.
The bag filter housing can be installed in the place of the HEPA filter using the filter tabs and Nylock nuts. The bag filter
is secured inside the housing with 4 P-clips. To remove the filter, turn the P-clips 90 degrees and pull it out. Then install
the new bag filter and secure it using the P-clips.

Vapor Trap Carbon Filter

Activated carbon filters are designed to remove odors and gaseous pollutants from air. These filters are an effective
and quick solution to your VOCs and odor problems. The selection of the carbon filter depends on the type and

amount of the gaseous pollutants. You will need to determine the requirements of your application. The Vapor Trap is
a disposable V-Bank, 24”x18”x12” filter and contains 27lb of activated granular carbon. It can be installed in place of a
HEPA filter. We recommend using our primary/secondary filter in front of the Vapor Trap to extend its odor absorption
capacity.

Troubleshooting

Your Omnitec Design machine is designed and engineered to provide years of trouble free service. Occasionally
problems occur. Here are some helpful tips and solutions.

The machine does not start

1. Check that the unit is plugged in and there is 115VAC available. Select either LOW or HIGH speed to turn the machine
on. If the red indicator light comes on, power is coming to the unit from the outlet.

2. Call Omnitec technical support to troubleshoot further.

The machine just hums when turned on

1. Unplug the unit.

2. Remove the HEPA filter and push the blower wheel by hand. If it does not move freely or if you hear a grinding/
scrapping noise as you spin it, then the blower wheel is touching the side of the blower housing. This may be due to
an impact of some kind and the motor mounts have been bent. Remove the motor/blower assembly and replaced
the bent motor mounts.

3. If the blower spins freely, check the capacitor. With the HEPA filter still removed from the machine, insure that the
wiring connected to the capacitor is plugged in and not broken. Re-plug the unit into the power outlet keeping the
switch in the OFF position. Then push the blower wheel and as it is spinning turn the speed selector switch to LOW. If
the machine keeps running, the capacitor needs to be replaced.

The machine will run for a few minutes then turn off

1. The machine must have a HEPA filter installed to operate properly. If you are trying to run it without a filter in place,
the motor will overheat within a few minutes and the thermal overload will engage and shut it down. Let he motor
cool off for 30 minutes, install the filter and try running the machine again.

2. If the filter is in pace and the machine still shuts off after a few minutes then the motor is faulty. Replace the motor.

The machine vibrates excessively when running

1. This is an indication that the motor bearings are worn out. If the machine continues running, at this point the
vibration will cause the center hub of the blower wheel to separate from the wheel requiring replacement of both the
motor and blower. Replace the motor.

2. If the machine does require electrical servicing of the motor or switches the following page contains a wiring
diagram to aid in repair or troubleshooting.
