ABOUT Your WM-RC2
TheWM-RC2 air purifier was designed to provide long service. The unit was designed to be easily
repairable. The product warranty is 7 years but you can expect 15 or more years of useful
product life. The WM-RC2 is a heavy duty all air purifier. There are no circuit boards. We use
simple switches that if necessary are easy to replace.
Unpacking
Your WM-RC2 air purifier is shipped on a 30" x 52" pallet. If you ever need to ship your air
purifier back to the factory it MUST be shipped strapped to a pallet. The WM-RC2 was designed
to be easily repaired so it is unlikely to need to ship your unit back. Care should be taken while
unpacking the MAX Guard. The unit is quite heavy and the box should be placed in the upright
position. It may be necessary to slice the corners of the box if you are unable to lift the unit out.
Installation (install with the exhaust at leat 6' 6" above the floor)
The WM-RC2 was designed to be mounted in a wall flush to it's surface. It was designed to fit
into a commercially studded wall with wall studs set on a 24" center. Such a wall has an
opening of 21.5 inches and the WM-RC2 will fit in this gap. The rough opening for the WM2-
RC2 should be 30.75 x 21.75
If the wall you are mounting the unit into does not have studs spaced at this commercial norm
you will need to build a frame with a rough opening of 30.75 x 21.75 and secure it to the wall
stud structure.
Wiring for your unit enters the unit through the side. When you purchased your unit you will
have chose the left or right hand wiring option. The wire entrance is located 2.75 inches from
the front and 21.25 inches from the bottom. The design intent is to have the power wire be fed
through a piece of rigid conduit and then into a junction box.

The internal control box is fitted with a 1/2 inch threaded receptacle. Thread a piece of rigid
conduit into the control box receptacle. Attach a junction box on the other side of the stud and
connect it to the rigid conduit (see image A-1 below) Feed the power/control wire through the
conduit and into the junction box.
6 conductor wire can now be run from the junction box to a standard gang box where the unit
control is going to be located (see image A-2) below.
Wiring with on board Potentiometer
If you ordered your unit with the potentiometer mounted in the unit you need only hook up
the building power to the unit. The wires coming from the unit will have 3 wires and they
need to be connected to line, neutral and ground.
Optional Trim Boards
The WM-RC2 will blend into the surrounding environment much better if you install a trim
package around the unit. There should be sufficient wall support on the edge of the frame you
built or the building internal wall studs. If you ordered the optional trim kit the trim pieces are
pre-cut and will fit well around the unit. Place the trim boards so the unit is centered within
the frame created by the 4 trim boards.

Getting to Know your WM-RC2
The WM-RC2 is sold with a number of different filter package options. Not all of the
following information will apply to your product. The filter options available are:
1. Standard HEPA
2. MERV 15
3. Electrostatic
4. HEPA / UVGI
All WM-RC2 filter packages include a pre filter and carbon filter. In the UVGI model the UV
bulbs are located behind the carbon filter incorporated into the UVC chamber. It is important
to regularly inspect, clean and replace filters as needed. Failure to do so may lead to poor unit
performance and voiding of the product warranty. The Blowers in this unit depend on air flow
to keep the cool. Insufficient air flow may cause the motor bearings to over heat and fail. The
Blowers are rated for 60,000 hours of normal use. Proper maintenance can greatly extend the
blower life.
Maintenance
Your LakeAir Air Cleaner is a high quality, precision piece of equipment designed for many
years of satisfactory performance. Adhere to a regular maintenance schedule and no
problems should occur. This unit should be checked periodically for “dust load” and cleaned
if found to have a large accumulation of dust and lint. Under regular conditions The HEPA
filter should last 1 year and be replaced annually. The carbon filter should be changed every
3-6 months. When odors are no longer being removed, it is time to replace the carbon filter.
The electrostatic filter cell should be washed every 3-6 months. The prefilter should be
cleaned every 3 months. When used in a smoky environment the WM-RC2 filters should be
serviced more often. The UVGI bulbs (UVGI units only) should be changed every 12 months.

Filter Removal and Installation
The pre filter is the first of 3 filters used in the WM-RC2. The pre filter removes large
particles from the air stream. It also extends the life of the main filter. The prefilters rating
is MERV 2 and its Part# is 490052. The pre filter is mounted into the door of the WM-RC2
To remove or re-install lift the end of the prefilter over the filter stop and slide along filter
channel

Main Filter
The main filter will be one of 4 different filters. Possible options are Standard HEPA
(20 x 16 x 4.75), MERV 15 Media filter (20 x 16 x 4), Electrostatic filter (20 x 16 x 4.5)
or UVGI HEPA (20 x 26 x 2.4) The main filters fit snugly into the filter box and can be
removed easily. All 4 filters have a lip that allows you to get a good hold on the
filters. The filter lip may be a bit sharp so take care not to cut yourself.
Move the filter back and forth with a side-to-side motion drawing it slowly to you.
You can reinstall the filter in the same manner gently moving the filter back into
place. The main filter should touch the carbon filter.
Carbon Filter
The carbon filter is located directly behind the main filter. To remove the carbon
filter, put your fingers on the lip of the filter and gently remove the filter with a side-
to-side motion. Note: The lip is metal and may be a bit sharp use caution not to cut
yourself while removing. In an UVGI unit the carbon filter is incorporated into the
UVGI chamber. You should never run the UVGI filter without a carbon filter both in
front and back of the UVGI element.

Electrostatic Cell Removing and Re-installing
CAUTION
Always Ground the Cell before handling!
When you open the door to the
Unit all power is cut off. It is
possible however that some
residual electricity is still residing
in the Filter Cell. So, the FIRST
thing to do is ground the voltage
side of the cell. To do this take a
Philips screw driver with an
insulated handle and touch both
the cell side and the ION Bar. This
will dissipate any residual charge.
Remove the ground screw. The
ground screw secures the filter
cell and provides the ground
needed to allow the filter cell to
function properly
Slide the cell out slowly, The Cell
Power Line is on the left hand side.
With the Cell partially out remove
the Power Line Plug. by
disconnecting from the Cell Power
Lug. Then remove the cell from the
air purifier.
To re-install: reverse these steps,
be sure that the power line is with
the cell frame and avoid crimping
the power. Line
