INTRODUCTION
HEPA AIR FILTRATION SYSTEMS
Congratulations! You have purchased a very effective air cleaning and treatment system incorporating HEPA (High Efficiency Particulate
Arrestance) filter technology. This is the type of air cleaning equipment that respiratory specialists recommend most.
To optimize the performance of your HEPA Filtration System, it should be installed by a professional contractor who is familiar with your indoor
air quality situation and the operation of other heating, ventilation and air conditioning equipment that you may have.

1. Using mounting plate, mark holes on
furnace return duct to be cut.
2. Cut holes in desired location and
attach mounting plate to duct with
screws.
3. Make sure the negative static pres-
sure tube from the pressure switch
is inserted into the return air duct
properly. The end of the tube should
be clear of any insulation or other
obstacles.
4. Attach HEPA unit to mounting plate
with screws.
5. Installing Grommet and Tubing
• First drill a 1/4" to 5/16" diameter hole in the duct wall on the
supply air side of the furnace duct. Carefully insert the grommet
into the hole. (Drilling a metal duct may produce burrs. Be care-
ful not to cut or pricked by the burrs or the duct.) Make a mark
a distance of1/2" from one end of the tubing. Slide this end of
the tubing through the center of the gr
ommet up to the mark as
illustrated.
6. Connect the other end of tube you connected to the supply air duct
to the positive port of the pressure switch located on the electrical
panel and marked "Pressure Switch"
7. Open the access door of the DM3000P and remove the carbon fil-
ter and the HEPA filter that are sealed in a plastic bag. Remove the
plastic bag and dispose of them appropriately. Insert the HEPA fil-
ter carefully then insert the carbon filter. Close and latch the
access door.
8. Switch rocker switch to "ST
ANDBY" or "CONTINUOUS".
OPERATION
Your Fantech HEPA filtration system incorporates three stages of filtration. Air is drawn from the house via one of the installation examples,
found in this manual, by a powerful efficient EBM fan. The air is cleaned as it passes through the filters, where it is then reintroduced back into
the home, cleaned of the majority of harmful particles.
The DM3000P includes a differential pressure switch. When rocker switch is set to "STANDBY" the DM3000P will remain OFF until the pres-
sure switch detects airflow in the forced air system's duct. As airflow is detected, the DM3000P is turned ON. When the rocker switch is set
to "CONTINUOUS" the DM3000P will operate continuously irregardless of the forced air system's operation. Finally, when the rocker switch is
set to "OFF" all power to the DM3000P is disengaged.
Note: A semi-annual service schedule must be followed to ensure the HEPA unit is operating at its full potential.
INSTALLATION
DM 3000P - Duct Mounted model
The return side of the furnace is the recommended location for the
HEPA to connect to.
IMPORTANT NOTICE:
1) The DM3000P should not be installed on its side. Should only be
installed like Option A & B.
2) Variable speed forced air systems or installation where the pres-
sure difference between the return air and supply air ducts are
less than 18 Pa (0.07 in wg) may not provide the required differ-
ential pressure to activate the DM3000P when set on "STANDBY".
The only remedy is to set the DM3000P on "CONTINUOUS" mode.
* Diagrams are examples only. Actual installation may vary.
Airflow
DM 3000P - (installation instructions)
Option A
Option B
A) Problem: When the DM3000P is on "STANDBY" it does not come ON.
1) The pressure switch's positive pressure port is not connected.
Solution: Use the supplied tube and grommet and install one end of the tube to the supply (positive pressure) air duct and the other
end of the tube to the pressure switch connection on electrical panel next to the power cord.
2) The pressure differential between the return (negative) air and the supply (positive) air of the forced air system is less than 18
Pa (0.07 in wg).
Solution: Check the static pressure difference by connecting the LOW pressure side of a manometer to the return air duct and the
HIGH pressure side of the manometer to the supply air duct. If it reads less then 18 Pa (0.07 in wg), the pressure switch will not
work. The only remedy is to set the rocker switch to "CONTINUOUS". Check this differential pressure on all available speeds of the
forced air system.
B) Pr
oblem: When the DM3000P is on "STANDBY" it does not turn OFF.
1) Other exhaust equipment in the house may interfere with the operation of the DM3000P by creating pressure differences in the
forced air system's duct work.
Solution: If this is a constant problem, disconnect the positive pressure tube from the DM3000P to the supply air duct. Check if
the DM3000P turns ON when the forced air system is on and turns OFF when the forced air system is OFF.
Depending on the furnace and the duct design, the negative static pressure in the duct may not be more than 17Pa (0.07"WC). As such, the
pressure switch will not activate the DM3000P while it is on "STANDBY" mode.
SERVICE
The useful service life of the filter media in the HEPA Filtration System is directly related to the volume of air passed through the system and the
amount of contaminants in the air. In a typical residential application, Stage 1 and 2, filters should be replaced every three to six months or when
needed. The Stage 3 HEPA filter should have a life span of two to five years, again, depending on the amount of particulate in the air and the main-
tenance of the Stage 1 pre-filter.
Stage 1 - Prefilter: Air passes through the prefilter where larger particles are taken
out of the air. (part number 410472)
Stage 2
- Carbon: Air passes through the carbon filter where some gases and odors
are removed. (part number 410473)
Stage 3
- HEPA: Air passes through the certified HEPA media where very small par-
ticles are removed. 99.97% of all particles 0.3 microns and larger that
pass through this stage are removed. Particles smaller than 0.3 microns
are also removed with less intensity.
If the air flow through your unit is noticeably reduced, you can inspect the
HEPA filter by removing it and seeing if the filter paper is darkened on the
inlet or outer side. If it is, the filter cartridge should be replaced. (part
number 410985)
Please contact your local Fantech dealer or call HEPA Customer Service at
1.800.565.3548 regarding replacement of filter media, warranty informa-
tion or if you have any questions or
concerns about the performance of your HEPA Filtration System.
