KWBIO1411 Water Cooled

KBIO1411 Air Cooled



BioKool’s exclusive four point air therapy process cools, cleans, disinfects and retards mold and microbe growth.

According to the CDC, hospital acquired infections are the fourth leading cause of death. The CDC recommends four lines of defense against infection which are pressure, filtration, purification, and dilution. Kwikool® Biokool™ targets these requirements, empowering health care facilities to meet their two primary goals, improving patient outcomes and also profitability.

Section One


Air Temperature Requirements

Kwikool® Biokool™ air vents are located both on the front and on the top of the unit. The vents require the environment maintain temperatures between 60° F and 110° Fahranheit. If the unit is operating in an environment above 110° F you will begin to notice performance diminishing. Eventually, this will cause the high pressure switch to trip, stopping the unit’s compressor.

The high pressure switch is a manual reset. A reset switch is located in the power cable receptacle box in the back of the system. Reset your Kwikool® system by pressing the red button. You will know when the system has been reset, when you hear a definite click. Standard air-cooled Kwikool® models are not designed to operate at temperatures below 60°F. Low-ambient temperature controls are special ordered. Temperatures below 60° F will cause the discharge air exhaust fan to cycle excessively. Excessive cycling will potentially damage the switch. If this occurs, seek a certified Kwikool® technician or void your warranty.

Biokool™ Capacity & Temperature Settings

When choosing which system is right for your particular application, use the standard rule of thumb.  Match the capacity of the unit to the rooms specific heat load, while maintaining a 72° F temperature. 

In order to reach temperatures below 72° F with Kwikool® Biokool™, the unit must have extra capacity, over the the above standard. It is our recommendation that the temperature is never set below 70° F. However, if you choose to do so, be sure you choose a unit with a cooling capacity in excess of the above standard measure. If you do not follow this recommendation, you will cause the unit’s evaporator coil to freeze up, resulting in diminished performance and also a dripping of condensation coming from the cabinet.


Do not place your Kwikool® unit in direct sunlight, The unit should be positioned so that the output of the unit can be focused as close to the heat generating equipment as possible with the front grill fully exposed.

Do not block the front of any Kwikool® system. Blocking will cause a restriction in the airflow and will result in low performance. If you are using a Kwikool® Biokool™ it is important that you position the unit in order to give plenty of room for air to flow. Blocking the air flow, could result in freezing the evaporator coil.

Section Four

Assembly & Installation

Air Chutes

Your unit may come equipped with air chutes, or you may have purchased them as an optional accessory. Install supply air flanges to the front of your KwiKool® unit above the control panel. Please look for step by step instructions which come along with the air chute kit.

Condensate Tank

BioKool™ systems come standard with an external 5-gallon condensate tank. The tank is equipped with a float switch that shuts your KwiKool® down and alerts operators with an alarm and display, when the condensate tank is full. It will read CF Condensate Full, on the screen. This prevents accidental water overflow on the floor. The alarm will clear automatically upon emptying the 5 gallon tank and reconnecting it. If connecting to a permanent drain, DO NOT connect or use the equipped tank.

To use the external condensate tank, remove the factory installed condensate float switch bypass plug on your KwiKool® unit and install the male connector jack supplied on the condensate tank. Next connect the factory supplied ¼” ID condensate tubing to the ¼” OD barbed condensate water outlet on the back of your KwiKool® and connect the discharge end of the tube to the ¼” barbed connector on the condensate tank. The condensate float jack must be inserted into the female condensate jack to operate your BioKool™. CF displays if the jack is not connected or the bypass plug is not inserted properly.

Condensate Water Outlet

The Condensate Water Outlet is located in the back of the unit in the cord compartment. Look for the 1/4” OD barbed fitting. Push to connect the clear tube to the fitting. 

The condensate float switch jack either connects to the condensate tank; or is bypassed by the factory installed male bypass switch, plug. You will find it next to the condensate water outlet.

Optional Ceiling Kit

Ceiling Kit Discharge Outlet (condenser exhaust) & Discharge Make Up (fresh air inlet). The ceiling kit is comprised of flanges with foam tape, fasteners, two (2) eight foot lengths of flexible duct, duct clamps, and one 24 x 24 in. replacement ceiling tile.

A Well Ventilated Space
Normally, the make up air and discharge air is directed above a drop ceiling. However, the ceiling kit is not limited to ceiling use and may be placed or fastened to any vertical surface or wall. The important thing is space must be well ventilated and large enough for the heat load to be absorbed. Condenser discharge air is prevented from entering the make up air inlet by way of a factory installed deflector on your Ceiling Kit.

The deflector should discharge from the rear duct. If the condenser discharge and return space is unventilated, or unable to handle the exiting heat load, KBIO’s high pressure safety switch will trip. If this occurs, you will get an “HP” on the control panel.

Resolve this by finding appropriate ventilation then reset the high pressure switch per the instructions in the troubleshooting guide. For areas with a closed ceiling or no ceiling use the double flange ceiling kit method or extended duct method.

Step One
Align the holes of the flange to the holes located on the top of the unit. Attach to the top of the BioKool™ system using the specially factory supplied fasteners.

Step Two
Attach each duct to the flanges on the replacement ceiling panel(s); secure the duct to each flange using the supplied clamps.

Step Three
Install the replacement ceiling panel(s) in the ceiling grid with the duct attached, connect the open end of the duct to the flanges on your KwiKool® and secure with supplied clamps. Your KwiKool® must have fresh make up air going to the condenser to operate at peak performance. Ensure the ducted space can absorb the heat load. It must be open enough to keep hot air from returning.

Step Four
KwiKool’s two duct ceiling kit (CK-12) is designed especially for KBIO models. BioKool™ is regularly used for primary, supplemental or standby cooling. In order to ensure you are able to utilize 100% of the units rated capacity and without creating a negative pressure in your conditioned space, use KwiKool’s custom ceiling kit. KwiKool’s exclusive IO integral condenser system isolates both the condenser discharge air and the condenser make up air from the conditioned space.

Section Five

Making Connections

Water Connection For KWBIO1411 Biokool™

KwiKool® BioKool™ KWBIO1411 is equipped with two brass female ½” (NPT) pipe thread connections located on the lower left corner of the back panel. Each fitting is labeled for water in or out. Use the proper sized wrench to connect either hard piping or the optional high-pressure line set, available in various lengths from the factory, be sure and use a backup wrench on the mounting bolt of the fitting to prevent the copper tube inside the cabinet from twisting when making your connections. 

Apply Teflon tape or pipe sealant to the thread for a good seal.  Water pressure should be limited to 150 PSI maximum and should be between 40° and 85° F. If the water supply is interrupted or the incoming water temperature is too high, the unit will shut down and go into an audio alarm and display HP on the control.  The high pressure switch is tripped and must be reset by pressing the HP reset button located in the return air compartment, be sure the water supply has been re-established to avoid future tripping. For long term use of water-cooled models a circulating water supply, such as a chilled water plant or cooling tower system is recommended.  Tap water is not an acceptable water source, due to the high water consumption.

Power Connection

Verify that the source power, phase and breaker size is compatible with your KwiKool® serial plate information and that the electrical circuit is dedicated only for the use of the unit. If you aren’t sure about your power, contact a licensed electrician. KwiKool® 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 feet and must be rated to operate your unit. Units that come supplied with a factory installed plug require the exact receptacle to match the plug and exact circuit size and power. Cutting the power plug on your unit will void its warranty.

Section Six

Filter Maintenance

Cleaning The Pre-Filter

Unplug System
Remove any and all power sources from the unit.

Access And Remove The Filter
Loosen the two screws on the filter access door until the door opens. Access the blue filter from the front panel. Pull it out from behind the door flanges.

Option One
In an open, well ventilated area blow out your blue pre-filter with compressed air away from you or others. Ensure to blow in the opposite direction of air flow. When facing the side you are blowing from, the cutouts for the door bracket should be on the left side. Blow until there is no more particulate coming from the filter.

Option Two
Using a hose or a sink, direct a flow of water through the filter from the outlet side to the inlet side. Wash and squeeze the filter until the water is clear.

Before reinstalling the filter, ensure that the pre-filter is completely dry. Typically a safe waiting time is three hours. This time will vary depending on conditions, so double check that your pre-filter is dry before installation. In order to minimize downtime; it is advised that you have two filters that can be switched out in order to continue using your portable cooling system.

Replace | Install The Filter
The replacement pre-filter must be inserted the same direction as the original pre-filter. Tuck the filter as deep as possible into the door flanges, or cutouts for the door brackets. When looking at the inside of the front panel, the two squares go on the left side so that the fastening screws go through the rectangular cutouts.

Latch The Panel Door Closed
Push front panel closed and tighten the screws until they are firmly secured.

Section Seven

HEPA Installation Steps

Unplug System
IMPORTANT: Remove any and all power sources from the unit. Unplug the unit.

Access The Filter
Gently loosen the two screws on the filter access panel door until the door opens.

Remove The Pre-Filter
Using the lip on the filter, pull the HEPA filter straight out.

Install The New Filter
Air flow direction is marked on the filter. Ensure it is facing the correct direction before securing it in the housing. The black rubber faces towards the interior of the unit.

Install Pre-Filter
Push the front panel closed and tighten the screws until they are firmly secured.

Section Eight

HEPA Maintenance

Kwikool’s KBIO BioKool™ system is a highly effective way to reduce microorganisms such as virus, bacteria, and mold spores. Filters also prevent dust and debris from circulating in the conditioned space. This portable system will come standard from the factory with both the pre-filter and HEPA filter installed on the evaporator inlet. KBIO’s filters are disposable and therefore must be periodically inspected and replaced based on the air quality of your conditioned space.

Encased in steel, HEPA filters measure 21 X 13.5 X 4 inches, and are lined with fibrous, filter material. Expect to replace each HEPA filter twice annually. The blue pre-filter is washable. If washed frequently, it will preserve the HEPA filter longer. Failure to maintain will restrict air flow, and lower the air quality, and overall performance of your system.

Section Nine

Ultraviolet Light

Biokool’s™ Ultraviolet germicidal lamp provides a much more powerful and concentrated effect of ultraviolet energy than can be found naturally. Germicidal UV provides a highly effective method of destroying microorganisms.

The UV spectrum has potential to either kill or inactivate microorganisms, preventing them from replicating. Biokool™ utilizes UVC energy at 253.7 nanometres to inactivate microorganisms, also known as Germicidal Irradiation or UVGI. UVC exposure inactivates microbial organisms such as bacteria and viruses by altering the structure and the molecular bonds of their DNS after UVC exposure, the organism dies off leaving no offspring, and the remaining population of the microorganism diminishes rapidly soon after. 


Section Ten

Ultraviolet Light Bulb Replacement

Unplug The System
IMPORTANT: Remove any and all power sources from the unit. Unplug the unit.

Open Access Door

Section Eleven

Application Requirements

Air Temperature Requirements In Cool Mode

Environmental requirements of your KwiKool® unit at the installation site are 0°F to 110°F for the condenser make up air located on each side of the unit. If the unit is operating in an environment above 110°F the high pressure switch may trip, causing the compressor to stop, or you may also notice diminished performance.

The High Pressure Switch is a manual reset type and located in the front service compartment on KPO5 and KPO12. The reset is located in the return air compartment on the KPO25 and the system is equipped with two (2) reset switches.

Reset is accomplished by pressing the button on the switch located on the compressor discharge line. If the switch has tripped, you will feel a distinct click upon reset. Standard KwiKool KPO models are not designed to operate at temperatures below 60°F on the cooling side. Temperatures below 60°F will cause evaporator coil freezing.

Capacity & Temperature Settings

Sizing of our units is based on matching capacity to a specific heat load while maintaining a 72°F temperature. In order to reach temperatures below 72°F the unit must have extra capacity. Therefore, we recommend that you do not set the temperature set point below 72°F unless you have excess cooling capacity beyond your heat load, since this may cause the unit’s evaporator coil to freeze up.

Section Twelve

Koolpad Operation

When you initially power up the system and select ON, you will discover the digital control of your Kwikool® system is factory set to COOL. The manual fan will be engaged and the set point is 72°F. The digital display will show the current room temperature and will automatically start cooling if the set point is under room temperature.

To operate the control press the  ON/OFF icon. A short press on this button turns the system on or off and the systems operates in the last parameter that was entered in operating Mode.

The control memory holds the last parameters entered. This includes ON and OFF if power is lost and then restored.

A light tap on the ARROW icons raise and lower the set point temperature in the current operational mode.

A light tap on the MODE button will enable you to adjust the operating mode  COOL and  FAN .

Fan Mode operates the supply air fan and UV Lights. You will know that the system is operating in this mode when the  FAN icon is steady.

Auto Fan initiates after a short press on the FAN button. It will activate either AUTO or MANUAL FAN. In AUTO FAN, the display will read AUTO FAN, and the supply air will operate only while the compressor is on.

In Manual Fan mode, the supply air fan is on, and the fan icon will not display. The supply air will operate at all times when the system is on.

Section Thirteen

Operation Control

Press  ON . COOL blinks when the time delay is complete. The hot air exhaust fan will ramp up as refrigerant pressure builds. It is normal for this fan to have a delayed start. Also, it’s normal for the fan to stop and start during the operating process, especially in low temperatures.

NOTE: The hot air exhaust fan (condenser discharge) operates exclusively in Cool mode and not in Fan mode.


When the system reaches the desired, programmed set point in COOL mode it will automatically begin cycling off or you may choose to turn it off. The system time delay will activate before cooling again. When cycling off by making the set point, the evaporator fan will remain activated if FAN is selected. When the temperature rises above the set point, cooling will begin automatically.

Turning the system OFF manually will turn the evaporator fan off also, impeding the BioKool™ from restarting automatically. In FAN mode the supply air fan and UV lights shut down when OFF is selected.

Section Fourteen

User Parameters

Enter this mode by short pressing the gear icon.

Start by going to SETTINGS. Use FAN and MODE to scroll. Use the UP and DOWN arrows to change values.

Hold MODE until it beeps and flashes a lock icon, then hold FAN until it beeps. Release FAN then touch it again, it will beep and then display P04.

To scroll use FAN and MODE. Select ON/OFF to exit, or after one minute the display defaults to the operating screen. Use the UP and DOWN arrows to change values.

Section Fifteen

Built In Safeguards

Protects your KwiKool® while in COOL mode from potential damage by delaying the compressor from starting before the pressures in the mechanical system equalize. Always activates when your KwiKool cycles off, is turned off, power is lost and then restored.

Protects your KwiKool® from potential damage to the mechanical system by shutting down and alerting operators of a condition such as stopped or slowed air flow over the condenser coil; make up air temperature above operating range or mechanical failure. Your KwiKool® will sound an audio alarm only and display HP on the control. To resume operation, the system requires a manual reset after corrective action is taken, the reset switch is located in the power cord pocket. Push in to reset, if activated you will hear a click. If this alarm is engaged the system will not operate in cool fan mode.

Protects your KwiKool® from potential damage to the mechanical system by shutting down and alerting operators of the condition. This safety activates when pressures below 20 PSI are detected in the mechanical system of your KwiKool®. Your KwiKool® will sound an audible alarm and displays LP on the control. Call 1-800-KWIKOOL if this alarm is present on start up. Automatic reset upon correction of low pressure condition. If this alarm is engaged the system will not operate in cool, fan or heat mode.

In the event of a power loss your KwiKool® resumes operation when the power is restored if in the ON position. All operational functions are preserved in the memory of the control.

BioKool™ systems are factory equipped with an internal high lift condensate pump. KwiKool® condensate pumps are able to pump the condensation collected in the reservoir of the pump to a drain or other area approved for the discharge water by attaching ¼” I.D. tubing to the ¼” O.D. barbed condensate outlet.

KwiKool® condensate pumps are equipped with a pump safety cut-off that prevents accidental water overflow by shutting your KwiKool® down and alerting operators with an audible alarm and displays CP on the control. Call 1-800-KWIKOOL if this alarm is present on start up. The most common reason for this alarm to activate during operation is restricted water flow thru the discharge tubing or excessive discharge line connected to the system. Automatic reset upon correction of the condensate flow. If this alarm is engaged the system will not operate in cool or fan mode.
