Pure n Natural Systems, Inc. recommends that a licensed electrician or licensed
contractor install units.
WARNINGS:

FILTER CHANGING:

3. H.E.P.A. Filter - Replace at least every 12 months.
Step 1. The Pre Filter is located behind the intake door (service door). The Pre Filter is a
blue and white polyester, pre-tack filter. The intake door is located closest to the
HI/LO/OFF switch on the face of the system. Unclip the two latches on the intake door
and the door will swing down. The Pre Filter is the first filter behind the intake door. Peel
away dirty Pre Filter and discard. Install the new Pre filter with the white side out. Close
door. DO NOT WASH PRE FILTERS.
Step 2. The carbon filter is located behind the Pre Filter. Follow Pre Filter changing
instructions from Step 1. Remove Carbon Filter, discard and replace with new Carbon
Filter. DO NOT WASH CARBON FILTERS.
Step. 3. Remove the adjustable louver door. Remove the H.E.P.A. Bar. The H.E.P.A.
Filter is a pleated media surface with a metal frame. Slip the H.E.P.A. Filter out of the

INSTALLATION OF MODEL FM22
FOR
SOLID CEILINGS
1. Remove the system from the shipping container and remove all 3 filters, including
HEPA filter and HEPA bar at exit end.
2. After deciding location and direction of air flow, locate the studs between which
the unit will be positioned.
3. Mark out the area where the ceiling will be cut. (Min. 47” x 22-½”)
4. Remove the piece of ceiling that has been cut, and remove all screws, nails, etc.
from the cut out area.
5. At this time, locate an electrical source from above the cut out area, and plug in
the unit.
6. Remove service door and screws that hold the door frame. Also remove
adjustable exit louver.
7. Raise unit into the ceiling. (Leave the unit protruding from the ceiling depending
on the thickness of molding that you are using to frame around unit.)
8. At this time, from inside the unit, affix (screw) unit to studs. Position the screws
as close to the top of the studs as possible. This will make the removal of the
adjustable exit louver easier. We suggest the use of 1-½” to 2” Phillips pan head
screws and fender washers for stability. We also suggest that you use 2 screws in
each quadrant for support.
9. Replace service door frame to unit, install Pre Filter and Carbon Filters, and clip
on the service door. At opposite end of unit, install the H.E.P.A. Filter and
H.E.P.A. bar. Replace the adjustable exit louver.
10. Frame unit in with your choice of material. (See #7)
