II / Description
A. KwiKool Bio Air, KBA series is designed as an attractive stand-alone negative air machine. It
comes equipped with a duct collar designed to attach to the top of your KBA. The size of the
collar for a 600 model is 8” the 1000 model is 10”and the 1800 model is 12”. All models can
use the optional 12 inch duct and collar (not included with the KBA600 or 1000 unit and is
designed for use with CK12S ceiling kit or 12” ducting). Ducting to outside the space is
necessary to create a negative pressure. Using the unit without ducting to outside of the
space allows the unit to be utilized as a HEPA filtered room air circulator.
B. KwiKool Bio Plus KBP series is a multifunctional machine. This product comes equipped with
2 cover plates and a duct collar that is 8” for the 600 model, 10” for the 1000 model and 12”
for 1800 models. All models can use the optional 12 inch duct and collar (not included with
the KBP600 or 1000 series units, and is designed for use with CK12S ceiling kit or 12”
ducting). By adding and removing the cover plates or collars, this versatile machine can
function as:
1. An Air Scrubber - only top plate installed
2. A negative Air Machine –Front plate installed and top collar with ducting installed
3. A combination Air Scrubber/Negative Pressure Machine. Only top collar and
ducting installed.
C. KwiKool Bio Extreme KBX series includes all of the features of the KBP, but also adds an
air ionizer feature that uses electricity to create negatively charged air particles that are
circulated in the area of operation and attract to positively charged air particles in your
operating space that may contain allergens and microorganisms that otherwise would be too
small to filter out or to light to settle in the ambient air. The combined air particles with the
contaminants and microorganisms can then be captured in your KBX HEPA filter and
exposed to the UV light; the process also reduces the amount of static electricity in the air.
This product comes equipped with 2 cover plates and a duct collar that is 8” for the 600
model, 10” for the 1000 model and 12” for 1800 models. All models can use the optional 12
inch duct and collar (not included with the KBX600 or 1000 series units, and is designed for
use with CK12S ceiling kit or 12” ducting). By adding and removing the plates or collars, this
versatile machine can function as:
4. An Air Scrubber - only top plate installed
5. A negative Air Machine –Front plate installed and top collar with ducting installed
6. A combination Air Scrubber/Negative Pressure Machine. Only top collar and
ducting installed.

III / Assembly and Installation-
A. KBA600, KBA1000 and KBA1800 Arrive from the factory ready to operate after it is removed from
the packing and the cabinet protective film is removed, remove the film by pulling down from the
top of the cabinet to expose the stainless steel surfaces. Only attachment of the collar, optional
ceiling kit or user supplied ducting is required.
B. KBP600, KBP1000, KBP1800, KBX600, KBX1000 and KBX1800 users will need to remove the
cabinet protective film by pulling down from the top of the cabinet to expose the stainless steel
surfaces and remove one or both cover plates on the supply air before operating and/or install the
duct collar to the top of the unit. See illustration. Remove the front cover plate by extracting the
4 screws on each corner of the front cover plate, replacing the screws into the unit when the plate
is removed. And/or removing the top cover plate by removing the 6 screws attaching the plate.
Install the included collar to the unit using the screws from the top plate, if using the unit to
produce negative air pressure. You may choose to operate the system with one or both plates
removed dependent on your application requirements. The front plate removed will direct the air
flow through the quad directional vents and the top plate removed will direct the air flow through
the top flange. When both plates are removed the supply air divides the airflow through both
openings.
C. Ceiling Kit- For all KBA, KBP & KBX systems (Optional Accessory used to create a negative
pressure in your space). The ceiling kit is comprised of a flange with foam tape, fasteners, 1 eight
foot length of flexible duct, duct clamps, and one 24”X24” replacement ceiling tile. The tile is used
in drop ceiling grids but is not limited to only that use. It can be used through any opening that is
approved for the filtered air to pass such as a window or a vertical opening in a wall.
Follow these installation steps:
1. Align the holes of the flange to the holes located on the top of the unit on the outside
perimeter of the installed collar; there is no need to remove the factory installed collar On 600
and 1000 models. 1800 models are equipped only with a 12” collar. Attach to the top of the
KBA, KBP or KBX unit using the factory supplied # 2 Phillips fasteners.
2. Attach the duct to the flange on the replacement ceiling panel; secure the duct to the flange
using the supplied clamp.
3. Install the panel in the ceiling grid or in your approved opening with the duct attached,
connect the open end of the duct to the flange on your KBA, KBP or KBX and secure with
supplied clamp. Be sure the area where you are ducting is approved for the filtered air.
4. **For Ceiling Kit Users** - This kit is used to create a negative pressure in your space by
ducting the filtered air out to a different sealed area, this allows fresh air to be pulled into your
space. Be sure the filtered air is approved to enter another space before installation. The
ceiling kit is not limited to ceiling use and may be used on any vertical or horizontal surface

that it can be mounted to. If utilizing this Kit, the space above the ceiling must be an open
plenum or have a makeup air and a path for discharge.
D. Freestanding Applications-For all KBA, KBP and KBX systems. Use your KBA, KBP or KBX
to filter and refresh air in your space by placing the system in the space you desire to operate in and turn
the system on to start the filtering process. The KBA, KBP and KBX will work to improve the overall air
quality by re-circulating the air in the room through its filters and on KBP and KBX systems filters and
Ultra Violet lights.
E. Charcoal Filter- Optional Accessory. Order installed from the factory or later as a user installed
option. The charcoal filter helps to eliminate and reduce odors in your space. See Appendix C for
installation and set-up guide.
Visit www.KwiKool.com for more information and a complete set up guide.
F. Power Connection - Verify that the source power, phase and breaker size is compatible with your
KwiKool Bio Air serial plate information and that the electrical circuit is dedicated only for the use of your
KwiKool Bio Air unit. If you aren’t sure about your power, contact a licensed electrician. KwiKool Bio Air
systems are factory equipped with 8 feet of power cable sized to meet the power requirement of your
system. Extension power cable is allowed but cannot exceed 25’ and must be rated to operate your
KwiKool Bio Air. KBA, KBP and KBX systems come supplied with a factory installed male power plug and
require the exact receptacle to match the plug and exact circuit size and power. Cutting the power plug on
your KBA, KBP or KBX unit will void its warranty.
IV / Operational Safeguards
Read the following safeguards carefully before installing your KwiKool Bio Air
A. Do not operate or install your KwiKool Bio Air unit in a potentially explosive, combustible, or
corrosive gas atmosphere.
B. Keep your KwiKool Bio Air system away from flammable materials and open flame.
C. To avoid electrical shock keep your KwiKool Bio Air system away from direct contacts with water
and any liquids. Do not touch your system with wet hands.
D. To insure your KwiKool Bio Air system is stable, the floor on which the system is to be place
should be level, free of vibration and strong enough to support the weight of your model.

E. Do not move the system while it is operating. Before moving the system, first turn system to OFF
then unplug the system from the power source. Then unlock casters.
F. Do not tilt or overturn your unit, since this could damage the components.
G. Do not place objects on top of your unit.
H. Do not insert your hand or any other object into the air supply.
I. Do not operate your KwiKool Bio Air system with its service doors open.
J. If your KwiKool Bio Air system makes abnormal noises or vibrations, call KwiKool at
1-800-594-5665.
V / System Operation KBP & KBX Only
A. Select your KBP or KBX operational function; before using your system, choose the operation you
would like your system to perform.
1. Use as an air scrubber- The KBP and KBX are the only products capable of being used in this
manner. The system is placed in the space that you would like to filter and refresh, be sure the filter grill is
fully exposed in the space. For odor control, add the optional charcoal filter to your system. KBP and KBX
systems also include dual UVC Ultra Violet lights with a reflective chamber to aid in reducing pathogens,
molds and biological contaminants. KBX systems have an air ionizer for added protection from
containments. When configured in this manner, the system works to remove particulates from the space
by pulling in the surrounding air, filtering it then processing the filtered air through the UVC lights. The
processed air is supplied back into the space. KBP and KBX gives you supply air distribution options.
Remove the front vent cover just above the control to allow the processed air to supply through the multi
directional vent, or you may choose to remove the top vent cover to allow the processed air to supply
through the top. Remove both vent covers to distribute the air through both supply points.
2. Use as a negative air machine-KBP and KBX systems can be configured to remove air from a sealed
space, creating a negative pressure in the space to allow for fresh air to be exchanged with the ambient

air, the filtered air discharged is directed out of the space. This is achieved with the optional ceiling kit
(see section III, paragraph B), or use the factory supplied flange on the top of the system by connecting
duct to the flange and directing it out of the space (25’ Max). The KBP and KBX600 systems are
equipped with an eight inch collar and the KBP and KBX 1000 are equipped with a ten inch collar, the
KBP and KBX 1800 is fitted with a 12” collar. All Bio Air systems can be fitted with a 12” collar for
optional ceiling kit use. Note: Be sure and remove the cover from the top flange before connecting duct
on KBP and KBX systems. Note: Reducing the diameter of the collars or duct will decrease the
effectiveness of your system.
3. Use as a Combination Air Scrubber and Negative air Machine, - KBP and KBX are the only
products capable of being used in this manner, to use, remove the directional vent cover and the top
cover, then attach the duct collar and duct. Direct the duct to your desired location outside of the space,
(25’ Max) or connect the optional ceiling kit (section III paragraph B). Your KBP or KBX is now configured
to be both an air scrubber and negative air machine and will supply filtered air back into your space
through the directional vent while ejecting processed air out of the space creating a negative pressure
that pulls in fresh air.
V / System operation KBA
B. Select your KBA operational function; before using your system, choose the operation you would like
your system to perform.
1. Use your KBA to filter and refresh air in your space by placing the system in the space you
desire to operate in and turn the system on to start the filtering process. The KBA will work to
improve the overall air quality by re-circulating the air in the room through its filters and supplying
the filtered air back into your space. For odor control order the optional charcoal filter with your
KBA system.
2. KBA systems can be configured to remove air from a sealed space, creating a negative
pressure in the space to allow for fresh air to be exchanged with the ambient air, the filtered air
discharged is directed out of the space. This is achieved with the optional ceiling kit (see section III,
paragraph B), or use the factory supplied flange on the top of the system by connecting duct to the flange
and directing it out of the space (25’ Max). The KBA600 is equipped with an eight inch collar and the
KBA1000 is equipped with a ten inch collar, the KBA1800 is fitted with a 12” collar. All KBA systems can
be fitted with a 12” collar for optional ceiling kit use. Note: Reducing the diameter of the collars or duct will
decrease the effectiveness of your system.

VII / Built in Features and Safeguards
KwiKool is proud to provide its customers with high quality features and safety devices that are not found
in most other brands.
A. Automatic restart- Your KBA KBP & KBX systems will automatically restart if power is lost and
then restored. The system resumes operation in the previous selected settings.
B. UV light safety switch- KBP & KBX Only, to prevent accidental exposer to the Ultra Violet light,
KwiKool engineers have added a switch to turn the system off and to activate an audio alarm with
the code A2 on the display screen when the HEPA filter is removed from the return air
compartment where the UV lights are located and the system is in the on position. The system
will resume operation when the filter is reinstalled and the system is in the ON position.

C. Filter and UV light elapsed time counter-KBP and KBX systems only. Users are able to set the
control to alert personal with a visual display on the control when maintenance is required to the
UV lights and filter (as described above). Your KBP and KBX will display FIL when the filter timer
has elapsed; the factory default setting is 90 days, the pre-filter may need to be inspected and
cleaned more often, see maintenance section VII. KBP and KBX systems will display UL when
the UV light timer has elapsed; the factory default setting is 15000 hours (625 days). The factory
recommends replacing both bulbs at this time to ensure best efficiency. See Maintenance section
VII for step by step instruction.
D. Filter air flow monitor-KBA systems only. Your KBA system will display a red indicator light on
the control panel that may flicker during the first stages of air flow restriction when it is time to
service the system air filters, the pre-filter may need to be inspected and cleaned more often. See
maintenance section VII for step by step instructions. Note: this function is only active in high
speed.
E. Locking casters-To prevent un-intended movement of the system, locking casters are installed
on the front of all KwiKool Bio Air systems. Move the system to a level surface and move the
locks on the casters to the ON position. Move to OFF when moving the system.
F. Stainless Steel Cabinet- Provides a durable and attractive package that will blend in to most any
environment.
G. Smooth and reflective insulation- Inside the return air compartment of the cabinet retards
pathogens and microbe growth and also reflects the UV light in KBP & KBX systems.
H. Washable and reusable pre filter- Factory installed in all KwiKool Bio Air systems to help
preserve the HEPA filter.
I. Optional Charcoal Filter-Removes odors from returned air and supplies refreshed air into the
space. Can be ordered from the factory or installed later on all KBA, KBP and KBX systems.
VIII / Application Requirements.
A. Positioning of Unit - The unit should be positioned so that the output of the unit can be focused
as close to the space to be filtered and refreshed as possible with the front grill fully exposed. Do
not block the front of the unit, since this will cause a restriction in the airflow and can cause low
performance.
B. Lock the casters-Be sure the system is on level ground to prevent un-intended movement of the
system. Move the lever on the casters to ON to secure the system.
C. Water and Moisture-The KBA, KBP & KBX is not rated for outdoor use; avoid using the systems
in damp and wet areas or transporting them in uncovered vehicles.
D. Power-Each KBA, KBP or KBX system must have its own dedicated power to operate. Extension
cords are allowed, but no longer than 25’.
VII / Maintenance

A. Pre Filter –KBA, KBP & KBX systems come from the factory with a washable pre-filter installed on the
evaporator inlet to prevent dust and debris from entering the HEPA filter that is also pre-installed. You will
need to periodically clean the pre-filter based on your air quality, for optimum performance inspect/clean
this filter every 30 days, and more often if operated in poor air quality. Open the filter access door, below
the control by releasing the 2 slotted fasteners on the right side of the compartment. Remove the pre-filter
from the door frame and use a compressed gas in an approved area wearing the proper PPE to blow
through the filter to remove loose particles and then rinse the filter with clean water, allow complete drying
before re-installing. Failure to maintain the pre filter will cause restricted air flow and low overall unit
performance.
B. Filter Replacement: ULPA/HEPA filters 21”X13.5”X4”.
For optimum performance, inspect/replace HEPA filters every 90 days of operation.
Unplug your system - Remove any and all power sources from the unit.
Access the filters - Loosen the two screws on the filter access door until the door
Opens.
Remove the charcoal filter (optional) - Remove the charcoal filter by sliding the filter forward past the
frame and set aside. Replace if needed.
Remove the ULPA/HEPA filter –Pull forward on the top of the filter until it stops, then pull forward on the
bottom of the filter until it stops, use this method alternating top to bottom until the filter clears the frame.
Do not jam the filter by pulling too hard.
Install the new ULPA/HEPA filter - Noting the correct air flow direction, push the
ULPA/HEPA filter into the housing.
Install the optional charcoal filter - Push the top edge of the charcoal filter into the lip of the frame and
then repeat for the bottom. Close the front panel. Push the front panel closed and tighten the screws until
they are firmly secured.
UVC Bulb Replacement KBP & KBX Only

(594-5665) for replacement UVC bulbs.
Bulb Replacement:
Unplug your system - Remove any and all power sources from your system.
Open the filter access door –Loosen the 2 slotted fasteners on the filter panel until the door opens.
Remove the optional charcoal filter, if installed by pulling it forward from the frame. Remove the
ULPA/HEPA filter –Pull forward on the top of the filter until it stops, then pull forward on the bottom of the
filter until it stops, use this method alternating top to bottom until the filter clears the frame. Do not jam the
filter by pulling too hard. Once removed, the return air compartment is revealed and the UV bulbs are
visible at the bottom of the compartment. For best results replace both UV bulbs at the same time to
ensure the most efficient operation of your KBP & KBX systems.
Unplug the UVC bulb - With one hand holding the plug and the other holding the white end cap of the
bulb in place, pull the two apart. Remove the bulb from your system - Reach inside the unit and pull the
bulb out of its retaining clips from the middle of the bulb. Properly dispose of the old UVC bulb.
Install the new bulb - Take the bulb in your hand, slide your hand with the bulb into
the cavity, then push the bulb in to its clip in the same manner you pulled the bulb
out.
Plug in the new bulb - Hold the bulb in place with one hand and push the plug on to
the connector with the other. Keep in mind that the connector is not meant for any
direction. The male connection will not match up with the female portion if the
orientation is incorrect. If they do not match up, rotate the plug 90 degrees and try
again.
Re-install filters and close the filter door - Rotate the screws clockwise to securely close the door.
C. Charcoal filter installation for all KwiKool Bio Air systems- This section covers the set up and
installation of the charcoal filter in the field, users that have ordered the charcoal filter installed from the
factory will not need to complete these steps. Open the filter access door –Loosen the 2 slotted fasteners

on the filter panel until the door opens. Remove the ULPA/HEPA filter –Pull forward on the top of the
filter until it stops, then pull forward on the bottom of the filter until it stops, use this method alternating top
to bottom until the filter clears the frame. Do not jam the filter by pulling too hard. Once removed, you will
see 4 rails attached to the sides, top and bottom of the compartment, these rails stop the HEPA filter from
going into the compartment. Remove the 2 5/16th fasteners that are in each rail and move each rail to the
next set of holes in front of the holes that you just removed the fasteners from.
Once all 4 rails have been moved back, re-install the HEPA filter. You will notice the HEPA filter recedes
back an extra 1”.
This allows the charcoal filter to be inserted flush into the frame. Install the charcoal filter by lining the
filter up with the space in front of the HEPA filter and push it into place, close the access door and
operate your KwiKool Bio Air system as normal.
D. Air Ionizer, KBX systems. The Ionizing device is located in the supply air compartment and requires no
maintenance. The Ionizing system is fully automatic and self-cleaning; the device is on when the KBX
system is turned to on, and off when the system is turned off.
VIII / Utilizing your KwiKool BIO AIR System
KwiKool Bio Air utilizes a process that is engineered to meet the high
Demand for cleanliness in a hospital or other critical environments. This
process significantly reduces airborne particulates and microorganisms
as well as drastically reducing the potential for air conditioner related
contaminates.
KwiKool’s Bio Air exclusive “air therapy” process:
Cleans - ULPA filter - a high efficiency ULPA filter which filters 99.999% of
particulates greater than .12 microns in size.
Disinfects –KBP & KBX only, Internal UVC light is used to further reduce microorganisms by irradiating
the internal surfaces of the return air chamber.
Retards Growth- Non porous and smooth surface insulation helps
drastically reduce the ability of molds or other microbes from attaching and forming in the return air
compartment.
