Rules for Safe Installation and Operation

READ AND SAVE THESE INSTRUCTIONS!
Please read instructions before installing and using the HEPA Central Air
Filtration System (HEPA system). This will help you obtain the full benefit of
the HEPA system you have selected. It will also help you to avoid needless
service costs.

1. Read this manual carefully. Failure to follow these rules and instructions
could cause a malfunction of the air filter or unsatisfactory service and
could void your warranty.

2. Follow a regular service and maintenance schedule to ensure efficient
operation.

3. For safety and optimized performance of your HEPA system, all
installation and maintenance must be performed by a professional heating
and ventilation contractor. The installer should be made aware of your
indoor air quality situation and be familiar with your heating, ventilation and
air conditioning equipment.

4. High particulate distribution may occur during initial start-up of this product
after installation or after scheduled filter changes. Individuals who are
highly sensitive to airborne particulates should not be in the building and
allow 24 hours of operation for removal of particulates from occupied
spaces before re-entry.

Introduction

Congratulations! You will quickly realize that you have purchased a very
effective air cleaning system. It incorporates state of the art HEPA
(High Efficiency Particulate Air) technology.

Your HEPA system comes with a limited warranty. With proper attention
to its care and maintenance, you will receive optimum performance.

If your indoor air has abnormally high concentrations of particulates, the life
span of the filter media may be shortened. Excessive particulates in the air
will reduce the expected life of the HEPA filter. Under normal conditions the
HEPA filter will last from two to five years.

Initially, the HEPA filter’s particulate removal efficiency improves with use.
However, the air flow through the HEPA filter media will decrease, as dust
builds up on the filter, thus lowering its ability to circulate and clean as much
air as when it was new. If the air flow through your unit is noticeably reduced,
you can inspect the pre-filter and HEPA filter to see if they should be replaced.
Replacement (or washing if foam) of the prefilter every 3 months will help
extend the life of the HEPA filter. Please contact your local Beam dealer
regarding replacement of filter media, warranty information or if you have any
questions or concerns about the performance of your HEPA system.

NOTE: This filtration system is an ADDITIONAL filter, and does NOT replace
the existing air handler/furnace system filter.

General Information

Media Filters

Media filters strain particulates from the air. The filter media needs to have
tiny holes to allow air to pass through, but not particulates. Filter types vary
for all sorts of purposes. The most effective and proven filter media is HEPA.
HEPA filter media is 99.97% efficient at capturing particles which are 0.3 micron
in size or larger.

Carbon Filters

Carbon media is used to capture chemicals and odors, also referred to as
V.O.C.’s. Chemicals and odors cannot be captured with media type filters.
Activated carbon collects chemicals and odors in a process called adsorption.

If air passes through the carbon filter before particulates are removed, the
surface of the carbon quickly gets covered with particulates, rendering it
ineffective at capturing chemicals and odors. If particulates are removed from
the air with a HEPA filter, virtually the entire surface area of the carbon can
be used to capture chemicals and odors. This increases the efficiency and
filter life of the carbon filter.

Separate HEPA and Carbon Filters

HEPA and carbon filters have different life spans. It is important for a filtration
system to keep the filter components independent from each other, so that
the filter that is dirty/saturated can be changed. This is more economical
than a system where you need to throw out two or three filters when only
one needs changing.

The HEPA System’s 3 Stage Filtration Process

The 3 stage filtration process is used to create a very effective filtration system.
Each filter is independent and can be changed individually.

• Stage 1: Pre-filter - The inexpensive foam pre-filter removes larger partic lates
from the air, thus prolonging the life of the HEPA filter.

• Stage 2: HEPA - The HEPA filter removes 99.97% of particulates 0.3 micron
and larger. The cleaned air then passes through the third stage filter.

• Stage 3: Carbon - The carbon filter is about 1/2 an inch thick to give it
plenty of surface area for removing chemicals and odors from the air. The
clean air is then reintroduced into the air you breathe.

Notes:

• Industry experience indicates that one (1) air change per hour generally provides adequate air cleaning. Actual results will depend on multiple factors such
as outdoor particulate levels, infiltration rate, indoor activities etc.

• Generally speaking, the more air changes per hour provided, the more effective a HEPA system will be. People with sensitivities may desire a higher number
of air changes per hour for cleaner air.

Forced air handler/furnace systems:

The HEPA system should be installed as a bypass system, with part of the
return ducted into the HEPA system. The filtered air is then rerouted back
into the return air, and continues through the system to be heated/cooled.

Typical Return to Return Application

For homes with upflow forced air handler/furnace systems.( Air handler/furnace
is shown in a typical basement.)

NOTE: This filtration system is an ADDITIONAL filter, and does NOT replace the existing air handler/furnace system filter.

Preparation:

Here are some things to consider as you decide where to install the
HEPA system.

Location:

• Make sure there is room to open the HEPA filter access panel for filter
changes/inspections.

• Keep the HEPA system in a location where you can still access the air
handler/furnace filter.

• Keep the HEPAsystem away from possible water damage.

• Vibration pads will reduce vibration for installations where the unit is placed
on the floor.

• Install HEPA System on floor or suspended platform. If the unit is suspended,
screws must not penetrate through the cabinet. Make sure that you have
the proper chains/straps/joists and equipment to keep unit secure. Intake
(Marked as ‘Air In’ on unit):

• Intake ducts should be installed upstream of any humidifiers and be
installed on the main return.

• Intake duct should be installed at least 6 ft. away from the outflow duct on
the main return. Outflow (Marked as ‘Clean Air Out’ on unit):

• Outflow duct should be installed as close to the air handler/furnace inlet as
possible but not directly into the return air elbow of the main return.

• If the unit is being installed independently of any other system, room diffusers
are recommended to help distribute airflow evenly in the occupied space.

Ducting:

• If HEPA system is installed where inlet and outflow collars face down, metal
elbows must be connected to both inlet and outflow collars.

• Each connection must be sealed with aluminum tape or mastic, including
all take offs.

• Installed duct runs should be as straight as possible (if the duct runs are
too long, reduced CFM may result).

• If duct is exposed to unconditioned air, externally insulated flex duct is highly
recommended.

• Externally insulated flex duct can also be used for noise reduction purposes.

• For best indoor air quality, do not use ductboard or fiberglass inside of ducts.

Electricity:

• The unit must be plugged into a grounded 120V, 60Hz outlet.

Typical Return to Return Application

For homes with horizontal forced air handler/furnace systems. (Air handler/
furnace is shown in an typical attic.
