Description
The Bluezone® PK-220 is an air purification
device that draws in air containing viruses,
old, spores or fungus, and discharges air with
a highly reduced concentration of these
infectious impurities. The unit is completely
self-contained. The facility, equipment, and
personnel have no contact with the process
that is cleaning the air.
The Bluezone unit’s operation is controlled by
a microprocessor-based controller that alerts
the user to any system faults.

Installation Guidelines
The Bluezone PK-220 offers variable
installation options with no additional
cabinetry required. Units can be mounted to
the floor, mounted to the wall, or installed in
2’ X 4’ drop ceiling grid. A mounting cleat is
provided and must be used in all floor and
wall applications to prevent tip.
The number of PK-220s used in the space
depends on the size of the room and the
desired number of additional air changes
per hour (ACH) to be provided by air
cleaning.
For an additional 1 ACH, use one PK-220
for every 1600 square feet of floor space.
For an additional 2 ACH, use one PK-220
for every 800 square feet of floor space.
For an additional 3 ACH, use one PK-220
for every 550 square feet of floor space.
If multiple Bluezone PK-220 units are being
installed in a room, the following are
recommended guidelines for the placement
of the Bluezone units:
1. Distribute the units relatively evenly
throughout the space.
2. Units placed on the floor should be
positioned against a wall to protect
against tipping.
3. If installing in drop ceiling tiles, ensure at
least one ceiling tile between the
Bluezone PK-220 and either a HVAC
diffuser or a light fixture.

Installation
Bluezone PK-220 can be mounted to the floor, mounted to the wall, or installed into a 2’ X 4’
drop ceiling opening.
Floor/Wall Mounting:
Overview
The Bluezone PK-220 unit can be mounted the floor or mounted to a wall with the cleat
provided. A wall mounting bracket is integral to the unit.

Preparation
Unpack the Bluezone PK-220 and locate the included wall mounting cleat. See arrows in Figure
4 for recommended fastener install locations.
Figure 4: PK-220 Wall Mounting Cleat
Securely fasten the mounting cleat to the wall using the recommended fasteners shown in Table
2. If installing to metal or wood studs the bracket must be secured to 2 studs. It is the installers
responsibility to determine fasteners. All fasteners must be rated for 120lbs or greater.
For floor placement, mount the cleat 41 ½” off the floor. The installation of the wall mounting
cleat is required to prevent the PK-220 from tipping. Failure to secure the PK-220 with the
mounting cleat can result in injury.
Figure 5: Cleat Mounting Height for Floor Placement of the PK-220

Document #: BPI-PM013-00

For wall mounting, Bluezone recommends mounting the cleat at 46” or greater off the floor for 4”
or greater of clearance from the base of the PK-220 to the floor. Provide a minimum distance of
6 in from the top of cleat to the ceiling.
Figure 6: Cleat Mount to Wall for Wall Mounting the PK-220
Securely fasten the mounting cleat to the wall using the recommended fasteners shown in Table
2. If installing the cleat onto a stud wall (wood or metal) locate the studs and fasten directly to
them. Follow anchor manufacturer specifications for selecting screws.

Ceiling Mounting:
Overview
The PK-220 is designed with the option to be installed onto a 2’ X 4’ opening in the grid frame of
a standard suspended ceiling with 2’ X 2’ or 2 X 4’ tiles.
Only mount the PK-220 to a properly installed and structurally strong suspended ceiling with
structural members above the ceiling tiles to attach support wires.
NOTE: It is the installer’s responsibility to:
●Determine if the drop ceiling structure is capable of supporting an additional load of 50lbs.
●Assure local building, electrical and safety codes are followed related to the installation of
this equipment.
●Provide electrical hookup cable as determined by an on-site electrician.
●Provide the 12-gauge hanger wire to support both the ceiling grid and the PK-220
Assembly and installation of the PK-220 is a “two-person” job to avoid injury and potential
damage to the unit. The installer could consider a duct lift to raise the PK-220 unit into the
ceiling opening.
Clearances
The PK-220 is inserted into the ceiling opening at an angle and then seated into the ceiling grid
as shown in Figure 11 and Figure 12. Clearance of 18” above the ceiling grid is needed in order
to accommodate the insertion of the unit into the ceiling.
Clearance on the sides of the unit is 12”.
Installer may use judgement to decrease clearance to 0 on one or two sides of the unit if there is
additional head height to maneuver.
