IMPORTANT SAFEGUARDS
READ AND SAVE THESE INSTRUCTIONS
Safety
This manual contains important instructions
and safety information about the Bluezone Air
Purification System. Observe the following
dangers, warnings, cautions and notices
when installing, operating and servicing the
Bluezone Model 450.
Electrical System
Energized electrical circuits present a
potentially life-threatening hazard.
Ensure the unit’s power cord is unplugged
before performing any installation or service
work.
Ensure there are no other electrical power
circuits connected to the Bluezone Model
450.
Do Not Operate unit with a damaged cord or
plug. Discard unit or return to an authorized
service facility for repair.
Follow all lockout/tagout procedures for all
electrical circuits.
System Operation
Do not operate the Bluezone Model 450
while fogging with chlorine bleach or other
disinfectant solutions. Disinfectants can
poison the Bluezone catalyst and reduce its
effectiveness.
•Turn off the Bluezone Units if
disinfectant fogging or cleaning is
underway.
•Turn Bluezone units back on after
disinfectants have dissipated.
Never hose down the Bluezone Model 450 or
clean with a water jet. Direct flow of water
onto the catalyst can reduce its effectiveness
in eliminating ozone.
Turn off Bluezone units and cover with plastic
if the room is being hosed with water or
steam.
System Maintenance
The Bluezone Model 450 contains 4 UV-C
light bulbs; the UV light is completely
contained inside the unit during operation.
Unplug or disconnect the unit from power
source prior to any servicing.
The Bluezone Model 450 has multiple safety
systems to ensure that you cannot view the
UV bulbs while they are operating.
Do NOT attempt to override the cover switch
to allow the bulbs to operate when the cover
is off.

Skin or eye damage may result from directly
viewing the light produced by the lamp in this
apparatus. Always disconnect power before
relamping or servicing. Replace lamps using
Lamp Replacement Kit Model No. 005-
000004, manufactured by Bluezone Products
Inc. and sold by Authorized Bluezone Partner.
Never look at an illuminated UV-C bulb
without proper eye protection against UV light
frequencies.
Description
The Bluezone® Model 450 is an air
purification device that eliminates airborne
contaminants including microbes (virus, fungi,
mold and bacteria) and odors.
The Model 450 can be installed into a
standard 2’x4’ tile or two 2’x2’ ceiling tiles with
a ceiling mounting kit, installed into Bluezone
by Middleby cabinetry,or located on a shelf.
The Bluezone Model 450 draws in air
containing viruses, mold, 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
ensures safe operation at all times and alerts
the user to any system faults.

Installation Guidelines
Place the Model 450 in the room so that air
flow from the HVAC system, fans or other
air flow systems does not blow directly into
or pull air through the Model 450 air inlet or
clean air outlet.
Ensure a minimum clearance distance of 2’
(0.6m) from an HVAC ceiling diffuser,
register or inlet grille to the Model 450.
Ensure a minimum clearance distance of
10’ (3m) from the air outlet of an air
conditioning or mini-split outlet to avoid
forcing excessive air flow through the
Bluezone unit.
Place the unit so that the control panel and
display are visible and accessible.
If multiple Bluezone Model 450 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. Generally spreading the locations
across the available space is good
practice.
3. Warning: If the unit is located in an
area with foot traffic and there is a
concern that it could be bumped by
personnel, it should be labeled with
colored tape to make it more visible
and reduce the risk of collision.
4. Warning: To avoid risk of injury
from bumping into the unit, use the
ceiling mount kit, Bluezone by Middleby
cabinetry, or mount on shelf above
head level.
5. Warning: Locate the junction
boxes for the units as close as possible
to the units to avoid the risk of hooking
the cord and pulling it out. If the
distance to the junction box is more
than 2’ (0.6 m), the cord should be tied
to the wall, rack, or ceiling to keep it
protected.

Electrical Installation
The Bluezone unit is equipped with a power
entry module.
Model 450-052 must be connected to 120V,
60Hz.
Model 450-055 must be connected to 240V,
50Hz.
The unit is cETLus listed at 120V.
The unit is CE marked at 240V.
The Model 450 is shipped with a 6’ (2m)
power cord for either 120V or 240V
depending on the model.
Plug the power cord into the power entry
module.
Once the Model 450 is positioned
mechanically in the space, plug the cord
into the nearest un-switched electrical outlet
rated to the voltage on the unit’s
model/serial number plate.
Secure the cord.
Warning The power cord is attached
to the front of the unit and may be caught
and pulled during activities in the space.
Secure the power cord to the shelving, wall
or other stable surface.
