Power cord with plug -
available on 1.1-ton thru 2.5-ton models
Condensate Tank - KwiKool systems come standard with an external 5-gallon
condensate tank. The external condensate tank is equipped with a float switch that
shuts your KwiKool down and alerts operators with an alarm and display CF
(“Condensate Full”) when the condensate tank is full. 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 conden-
sate 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 conden-
sate tank. The condensate float jack must be inserted into the female condensate jack
to operate your KwiKool. CF displays if the jack is not connected or the bypass plug is
not inserted properly.

Align the holes of the flange to the holes located on the top of the unit. Attach to the
top of the KwiKool unit using the factory supplied fasteners.
Attach each duct to the flanges on the replacement ceiling panel(s); secure the duct
to each flange using the supplied clamps.
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. Be sure the area where you are ducting can absorb the heat load
and is open enough to keep the system from returning its own hot discharge air.
Your KwiKool must have fresh make up air going to the condenser to operate.
**For Ceiling Kit Users** - The standard two duct ceiling kit (CK-XX) is recom-
mended to be used with KIBXX models for optimum performance. KwiKool’s Iceberg
(KIB) units may be used for primary, supplemental or standby cooling. Using
KwiKool’s exclusive ceiling kit ensures that you are able to utilize 100% of the units
rated capacity and without creating a negative pressure in your conditioned space.
KwiKool’s exclusive IO integral condenser system isolates both the condenser
discharge air and the condenser make up air from the conditioned space.
**Note: The space where the make up air and discharge air is directed (normally
above a drop ceiling) 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. Make sure that the
deflector is on the discharge (rear) duct from the unit. However if the condenser
discharge and return space is unventilated, closed off or unable to handle the heat
load, the make up air will continue to get hotter until the system is not able to handle
the high heat buildup. This will lead to the unit tripping its high pressure safety
switch. If this occurs, you will get an “HP” on the control panel. To resolve, fix the
lack of make up air and reset the high pressure switch per the instructions in the
Troubleshooting Guide section. Additionally, the ceiling kit replacement panel is not
limited to ceiling use and may be placed or fastened to any vertical or horizontal
surface providing the discharge and make up air is able to be directed to the space
where it is mounted. For areas with a closed ceiling or no ceiling use the double
flange ceiling kit method or extended duct method.
Visit www.KwiKool.com for more information and a complete set up guide.
Follow these installation steps:

Ceiling Kit (Optional Accessory) - The ceiling kit is comprised of flanges with foam
tape, fasteners, two (2) eight foot lengths of flexible duct, duct clamps, and one
24”X24” replacement ceiling tile for KIB 1411 and KIB1811. All other KIB models use
two (2) 24”X24” replacement ceiling tiles.

III / Operational Safeguards
Do not operate or install your KwiKool unit in a potentially explosive, combustible, or
corrosive gas atmosphere.
Keep your KwiKool system away from flammable materials and open flame.
To avoid electrical shock keep your KwiKool system away from direct contacts with
water and any liquids and do not touch your system with wet hands.
To insure your KwiKool 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
KwiKool model.
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.
Do not tilt or overturn your unit, since this could damage the compressor.
Do not place objects on top of your unit.
Do not insert your hand or any other object into the cold air supply chutes.
Do not operate your KwiKool system with its service doors open.
If your KwiKool system makes abnormal noises or vibrations, call KwiKool at
1-800-594-5665.

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 your KwiKool 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’ and must be rated to operate your KwiKool.
KwiKool units that come supplied with a factory installed plug require the exact recep-
tacle to match the plug and exact circuit size and power. Cutting the power plug on your
KwiKool unit will void its warranty. All other KwiKool systems over 3-tons are not
equipped with a male plug and must be hard wired by a qualified personal.
**Note: 208/230 volt systems require voltage to be selected to the proper voltage
before operating your unit. This is controlled by a rocker switch located on the top of the
control box in the service door. The factory default selection is 208 volts for KwiKool
systems purchased after June 2016 and 230 volts for equipment purchased before this
date. Always set teh voltage incoming to the correct setting to avoid potential opera-
tional issues. Read the Operational Safeguard section before applying electrical power.
D.
Read the following safeguards carefully before installing your KwiKool:

Page 7
IV / System Operation
Apply Electrical Power - Once power is engaged by plugging in your system
and/or switching the breaker to the on position, your KwiKool display will come alive
and show the current room temperature. The unit is set to OFF and the fan is set to the
default position. A 2 minute time delay starts, indicated by a flashing F on the display. If
you are not seeing anything on the display, refer to the Troubleshooting Guide section
of this manual.
Control Panel - The control panel display shows the current operational status of the
unit.
ON/OFF Button - Pressing this button on your control panel engages or shuts
down your KwiKool system. All settings selected are stored in the microprocessor
board even if the power is lost including the ON/OFF selection. Refer to the
Troubleshooting Guide section of this manual if your KwiKool is alerting an alarm
after selecting ON.
MODE Button - Depressing the MODE button selects your choice of operations.
Cool, for cooling with compressor operation. “Cool” will flash when the compres-
sor is running. “Cool“ will not flash when the room temperature is equal to or lower
than the set temperature or the system is timing out. Fan, for air circulation without
compressor operation.
F/C - Selects the way that room temperature and set point are displayed on the
control panel. Choices are Fahrenheit or Celsius. F is the factory default. This
indicator will flash when the system is in “time out” to prevent compressor short
cycling.

Single Speed Models - KIB 2411, KIB6023, KIB6043, **KIB12023,
**KIB12043. On the single speed models, pressing the fan key cycles the
supply air fan between auto fan and fan on. When the system is in auto fan,
the supply air fan only operates when the compressor is running. When the fan
is set to on, the fan runs continuously as long as the unit is in the ON position.
The fan speed window will be blank on these models.
Three Speed Models – (All other models NOT listed above.) The supply air fan
control button has several functions. First pressing the fan key will cycle
through the fan speeds. Each press cycles from low, med, high, and
multispeed. Multispeed will display all three speeds and flash only the speed
currently in use. The fan speed is automatically adjusted based on demand.
The second function is to change from auto fan to fan (constant fan). To
change this function, press and hold the fan key until the indicator changes
from fan (constant fan) to auto fan. When in FAN MODE, auto fan is not
available. If the unit was set to auto fan before changing the mode to fan, auto
fan will return when the unit is set back to COOL. Factory default is fan
(constant fan) and is the best choice for electronic equipment.
**KIB12023 and KIB12043 - These models are 2 stage systems and have a
fan speed for each stage. This feature is not user settable. This system
always starts in first stage fan speed (low) in COOL or FAN MODE, second
stage fan speed (high) only operates in COOL MODE when the second stage
compressor is running.

Turn On Your KwiKool System - Pressing the ON/OFF button once on your control
panel will put your unit in the ON position and “ON” will be displayed on the right
side of your display as well as the previously chosen mode.
System Operation -

Page 8
Up (+) and Down (-) Arrow Buttons - Raises or lowers the desired set tempera-
ture. When changing the set point, pressing the + or – key, the word SET will
appear on the display and the current set point flashes ON and OFF. The value of
the set point is changed 1 degree each time the + or – is pressed. The adjusted set
point flashes on and off 12 times after the last change and then returns to display
the room temperature.
a.
b.
Lowering or raising the set point will not change the temperature of the
supply air. For best results always adjust the set point to a temperature your
KwiKool can cycle on and off at to avoid operational issues such as freezing or
rapid discharge fan cycling, KwiKool systems are designed to maintain the set
point when sized properly and constant operation without achieving the set
point may shorten the expected operational life of your system.
The lowest set point temperature available for your KwiKool is 60 degrees F,
and the highest setting is 95 degrees F. The control will not allow adjustments
beyond these ranges.

V / Built in Safeguards
KwiKool is proud to provide its customers with high quality features and safety devices
that are not found in most other brands.
COOL - If the unit was previously set to the cooling mode (cool) then “cool” will be
displayed. If the compressor is running, the ”cool” on the display will be flashing. If
your unit has been sitting for over 2 minutes, this should happen immediately upon
turning the unit on, unless your set point is lower than the current room tempera-
ture. In this case your unit is ready to automatically turn on once the temperature
rises above the set point. If the unit was recently turned off or the unit turned itself
off because it reached the set point, the compressor will not turn on until the
system waits for approximately 2 minutes. This prevents the compressor from
being damaged do to a condition called short cycling. The indicator that the unit is in
the “time out” condition is that the F (or C) in the display will be flashing. When the
compressor starts, the F will stop flashing and the “COOL” will begin flashing.
Note that the condenser fan will not start immediately with the compressor. And
once the condenser fan kicks in and if the ambient temperature entering the make
up air for the condenser return is below 75 degrees F you may notice the fan
cycling on and off, this is normal. For KIB120 models, the fan will instead speedup
and slowdown in lieu of turning on and off. If the display flashes 99, this indicates
ambient temperature of 99 degrees F or more. This is normal and will stop flashing
when the ambient temperature falls below 99 degrees F.
FAN - If the unit was previously set to the fan mode then “FAN” will be displayed
and the fan will start to run.
2.
3.
Time Delay - Protects your KwiKool from potential damage by delaying the compres-
sor from starting before the pressures in the mechanical system equalize. This always
activates when your KwiKool cycles off, is turned off, power is lost and then restored or
the operational mode is changed. Display flashes C or F if the time delay is activated.
Condenser Fan Cycling or Condenser Fan Speed Control - Part of your
KwiKool limited freeze protection and works by regulating the discharge air flow to keep
the refrigerant pressures at the optimum range.
High-Pressure Switch and Alarm - Protects your Iceberg Series unit from
potential damage to the mechanical system by shutting down, sounding an audible alarm
and displaying a fault code (HP) when the system pressure exceeds safe operating
conditions. The high pressure switch is a manual reset switch and must be reset after
the switch is activated and the condition causing the trip is corrected.
Low Pressure Switch and Alarm - Protects your KwiKool from potential damage
to the mechanical system by shutting down the system, sounding an audible alarm and
displaying a fault code (LP) when the low side pressure is too low. This is normally
caused by low refrigerant charge. This switch is an automatic reset.
Automatic Restart - In the event of a power loss your KwiKool Iceberg resumes
operation when the power is restored. All operational functions are preserved in the
memory of the Microprocessor Board including the ON/OFF selection.

Condensate Pump & High Level Alarm - All KIB Iceberg models are factory
equipped with an internal high lift condensate pump. KwiKool condensate pumps are
able to pump the condensation either to the factory supplied condensate bottle, or to a
drain or other location as required by the application. The internal pump is rated at 20
foot of head pressure. This means it can pump water to a maximum of 20 feet vertically.
Each pump is equipped with an overflow safety cut-off that automatically shuts your
Iceberg unit down, sounds an audible alarm and displays a fault code (CP). This prevents
accidental flooding of the conditioned space.
Condensate Tank & High Level Alarm - All KIB Iceberg models come standard
with an external condensate tank. The tank is equipped with an overflow safety cut-off.
When the tank is full, the safety will automatically shut down your Iceberg unit, sound an
audible alarm and display a fault code (CF) This prevents accidental flooding of the
conditioned space. If you are using the supplied bypass plug and not using the tank this
alarm is nonfunctional.
Power/Phase Monitor (Optional) - The KwiKool Phase Monitor is available as an
option on all 3 phase KwiKool models. The phase monitor samples the power supply for
low or high voltage, out of phase and loss of phase. If any of these power conditions
arise, the Phase Monitor will automatically shut down your Iceberg unit, sound an
audible alarm and display a fault code (A1). This alarm will reset automatically when the
power is restored to normal.
Service Ports - Located in the filter access compartment in the front of your KwiKool
below the control panel. This gives service personal a connection point for service
gauges to monitor the operating pressures of your Icebergs refrigeration system.
Sight Glass/Moisture Indicator - Located in the discharge air make up inlet. This
feature allows operators and service personal to view the condition of the refrigerant
returning to the evaporator coil. Used as a diagnostic tool by qualified personal.

VI / Application Requirements
Air Temperature Requirements - The environmental requirements of your
KwiKool unit at the installation site are 60 to 110 degrees F for the condenser make up
air located on the front inlet on the top of the unit. If the unit is operated in an environ-
ment above 110 F the high pressure switch may trip, stopping the unit’s compressor.
You also may notice diminished performance. The High Pressure Switch type is a
manual reset. The reset switch is located in the Return Air grill filter compartment.
Reset the unit by pressing the button labeled HP Reset. Standard air-cooled KwiKool
models are not designed to operate at temperatures below 60 degrees F. Low-
ambient temperature controls must be special ordered at an additional cost.
Temperatures below 60 degrees F will cause the discharge air exhaust fan to cycle
excessively and may damage the fan cycling switch, which requires qualified service
personal to repair and can void your warranty.
Capacity & Temperature Settings - Sizing of our units is based on matching
capacity to a specific heat load while maintaining a 72 degree F temperature. In order
to reach temperatures below 72 degrees F, the unit must have extra capacity. There-
fore, we recommend that you do not set the temperature set point below 70 degrees
F, unless you have excess cooling capacity beyond your heat load, since this may
cause the unit’s evaporator coil to freeze up.

VIII / Utilizing your KwiKool System
In contrast to conventional air conditioners, which circulate air conditioning capacity evenly
to an entire floor, KwiKool systems are designed for cooling an area with a high concentra-
tion of heat load, usually from electrical or computer equipment. Understanding the capabili-
ties of your KwiKool can help you avoid problems. For example, if you add heat-generating
equipment to the room after purchasing a KwiKool system, you may be short of the
necessary cooling capacity. Your KwiKool system offers an effective affordable solution for
many applications. It can also provide spot cooling for workers or process cooling within a
large space without the use of condenser ducting, such as a warehouse factory, or produc-
tion areas. If the system is used in this manner, the cold air supply must be within 5 feet of
the person or equipment being cooled, since the hot ambient air will mix with the cool air
very quickly. Your KwiKool system is specifically designed to adapt to today’s high tech
environments such as telecommunication or computer rooms and is equipped with the
necessary controls to maintain those special environments. Call your nearest KwiKool
Distributor or 1-800-594-5665 for help or for questions about other applications.
VII / Maintenance
Air Filters - Your KwiKool unit comes from the factory with filters installed on the
evaporator inlet to prevent dust and debris from entering the system and circulating in
the conditioned space, factory installed filters are a disposable type and must be
periodically checked and replaced based on the air quality of your conditioned space.
Failure to maintain the filters will cause restricted air flow and low overall unit
performance. The air filter is located on the front of your KwiKool unit below the
control, release the 2 slotted fasteners on the access door to open.
Conditioned Air Supply Drive Belts - Your KwiKool KIB120 models moves air
over the evaporator coil to remove heat and moisture from the conditioned space by
way of a motor attached to a blower wheel, this wheel turns by way of a pulley and belt
system. Inspect/adjust these belts every 60 days of operation, replace as needed.
Failure to maintain the drive belts will cause low performance, coil freezing or in
extreme cases damage to the blower/motor in the event of a belt breaking. Located in
the left side evaporator access door as you face the control panel. When adjusting the
belts, adjust them from the base of the motor. Do NOT adjust the sheave (pulley).
B.
A.
Positioning of Unit - 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 the unit, since this will cause a restriction in the airflow and can cause low
performance and/or evaporator coil freezing.
C.

IX / Fault Codes
Your KwiKool Iceberg System incorporates a self-diagnostic system that sounds an audible
alarm, stops your system and displays a fault code to indicate the nature of the problem on
the display panel. See the troubleshooting guide later in this manual for further information.
CF = Condensate Tank Full
CP = Condensate Pump Fault
HP = High Pressure Switch Tripped
LP = Low Pressure Switch tripped or tripping
A1 = Phase Monitor Senses power problem (if equipped)
