Unit Components

Description

1. Bio Air KBA series is designed as an attractive stand-alone negative air machine. It comes equipped with a duct collar designed to attachto the top of your BIOAIR. The sizeof the collar for a 600 model is an 8” and the 1000 model is10”. Both models can also accept an optional 12 inch duct and collar (not included with the 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.
2. BioAir KBA Plus series is a multifunctional machine. This product comes equipped with 2 plates and a duct collar. By adding and removing the plates or collars, this versatile machine can function as:
3.  An Air Scrubber – only top plate installed
4. A negative Air Machine – Front plate installed and top collar with ducting installed
5. A combinationAir Scrubber/Negative Pressure Machine. Only top collar and ducting installed.

Assembly and Installation

1. KBA600 and KBA1000Arrive from the factory ready to operate after it is removed from the packing. Only attachment of the collar, optional ceiling kit or user supplied ducting is required.

2. KBA600P and KBA1000P users will need to remove one or both cover plateson the supply air before operatingand/or install the duct collar to the top of the unit. See illustration. Remove the front cover plate by extracting the 4screws 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.

3. Ceiling Kit- For all KBA& KBAP 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:

4. 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. Attach to the top of the KBA or KBAP unit using the factory supplied # 2 Phillips fasteners.

5. Attach the duct to the flange on the replacement ceiling panel; secure the duct to the flange using the supplied clamp.

6. 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 or KBAP and secure with supplied clamp. Be sure the area where you are ducting is approved for the filtered air.

7. 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 exhaust.

8. Freestanding Applications-For all KBA and KBAP systems. Use your KBA or KBAP to filter and refresh air in yourspace by placing the system in the space you desire to operate in and turn the system on to start the filtering process. The KBA and KBAP will work to improve the overall air quality by re-circulating the air in the room through its filters and on KBAP systems filters and Ultra Violet lights.

9. 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.

10. 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 and KBA Plus 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 or KBAP unit will void its warranty.

System Operation KBA Plus Only

Select your KBAPlus operational function; before using your system, choose the operation you would like your system to perform.

1. Use as an air scrubber- The KBAPLUSis the only product 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. KBA PLUS systems also include dual UVC Ultra Violet lights with a reflective chamber to aid in reducing pathogens, molds and biological contaminants. When configured, the system works to removeparticulates 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. KBA PLUSgives you supply air distribution options. Remove the front vent cover just above the control to allow the processed air to supply through the multidirectional 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-KBA PLUS 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 KBA600P is equipped with an eight inch collar and the KBA1000P is equipped with a ten inch collar, the KBAP 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 KBA PLUS 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, -KBA PLUS is the only product 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 KBA PLUS 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.

Application Requirements

• 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.
• 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.
• Water and Moisture-The KBA & KBA Plus is not rated for outdoor use; avoid using the systems in damp and wet areas or transporting them in uncovered vehicles.
• Power-Each KBA or KBA Plus system must have its own dedicated power to operate. Extension cords are allowed, but no longer than 25’.

Maintenance

1. Pre Filter- KBA& KBAP 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.
2. 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) – Removethe 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 theoptional 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.
