INSTALLATION OF PAC-22 AIR CLEANER
EQUIPMENT:
1. Each PAC-22 unit is equipped with two (2) eye bolts, two (2) eye lags and industrial
hanging wire for easy installation.
2. The PAC-22 has an eight foot power cord and a three prong grounded plug. Electrical:
120 Volts, 4.2 Amps.
3. Each unit includes a one year supply of filters consisting of twelve (12) pre-filters, three
(3) charcoal filters and one (1) H.E.P.A. filter.
INSTALLATION:
1. Remove the system from the shipping container. Remove grill from intake side of the
system. Remove filter retainer bar and all 3 filters including pre-filter, carbon filter and
HEPA filter. (Replace these filters after the system has been completely installed.)
2. On either side of the system there are two mounting holes where the eye bolts are
inserted. It is easiest to screw the eye bolts into these mounting holes before mounting
into the ceiling. If the area above the drop ceiling is tight for space, then you may need to
put the eye bolts in the mounting holes after you have the system into the drop ceiling.
3. Remove the ceiling tile(s). The system will fit into one 2’x 2’ tile.
4. Locate a joist, girder or beam that is directly above the tile where your system will be
installed. After you have located a joist, girder or beam, drape the industrial hanging
wire over the apparatus so that either side is evenly dispersed. Line up the eye bolts with
the hanging wire so they are vertical. Thread one end of the hanging wire through one of
the eye bolts, loop the wire and twist tightly together. Thread the opposite end of the
hanging wire through the opposite eye bolt. Pull the wire tight. The system should be
only slightly resting on the grid work of the drop ceiling. After you have adjusted the
weight of the system on the grid work, then loop the wire and twist tightly together.
5. Locate a stud in the solid ceiling that is directly above the tile where the system will be
installed. Fasten the eye lag into the stud making sure to line up the eye lag with the eye
bolts on the system so the hanging wire will hang vertically. Thread the hanging wire
through the eye lag so that either side is evenly dispersed. Thread one end of the hanging
wire through one eye bolt, loop the wire and twist tightly together. Thread the opposite
end of the hanging wire through the opposite eye bolt. Pull the wire tight. The system
should be only slightly resting on the grid work of the drop ceiling. After you have
adjusted the weight of the system on the grid work, then loop the wire and twist tightly.
6. Install pre-filter, carbon filter, HEPA filter and HEPA bar. Replace intake grill.

SOLID CEILING INSTALLATION OF PAC-22 AIR
CLEANER
(Installation for 24” on center construction)
1. Remove the system from the shipping container. Remove grill from intake side of the
system. Remove filter retainer bar and all 3 filters including pre-filter, carbon filter and
HEPA filter. (Replace these filters after the system has been completely installed.)
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. 24” 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. 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.)
7. 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. 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.
8. Install pre-filter, carbon filter, HEPA filter and HEPA bar. Replace intake grill.
9. Frame unit in with your choice of material. (See #6)
