2. ASSEMPLY AND INSTALLATION
a. Air Chutes (If Equipped) – Using the quick connect clamps (supplied); install two
cooling air chutes to your KwiKool portable air conditioner. Slide the plastic
flexible air chutes onto the metal flanges on the top front of the unit and tighten
the screw part of the clamps until snug to secure the chute. If the chute does not
fit, adjust the chute by a slight twist counter clockwise to open it further.
b. Condensate Tank – KwiKool units come with an external 5-gallon condensate
tank, except for the KPAC units, which have a built in tank. Both the internal and
external condensate tanks are equipped with a float assembly for automatic unit
shut down, when the condensate tank is full. The external tank’s condensate line
is attached to ¼-inch nipple located next to the power cord on the back of the
unit. The tank also has an attached plug jack, which is inserted into the female
hole above the nipple on the unit. If the plug jack is not inserted, the unit will
go into alarm and will not operate until the jack is inserted. An independent
condensate line can be used instead of the condensate tank. (See section 3.e.
Condensate Pump.)
c. Ceiling Kit (Optional Accessory) – The ceiling kit is comprised of two flanges
with screws, two 8-foot lengths of duct, duct clamps, and one (for 1.5-ton units
and below) or two (for all other air-cooled units) 2-foot by 2-foot replacement
ceiling tiles. Attach the flanges to the top on the unit, and then attach the duct to
each flange using the hose clamp. The other end of the duct is attached to the
replacement ceiling tile. If the optional ceiling kit is used, follow these guidelines
carefully. First, check above the ceiling to make sure that it is open to the whole
floor. If the sheet rock surrounding the room extends to the next floor
above the ceiling, above ceiling ducting is required through the sheet rock,
using a double flange ceiling kit. If the hot condenser air is ducted to dead
air space, the pressure will back up into the machine shutting it down, due
to high head pressure. If above ceiling ducting is used, check the model
specifications for the maximum condenser duct length. After you have
determined that the area above the ceiling is open to the whole floor, attach the
supplied duct to the replacement ceiling tiles using the clamps in the kit. Then
remove the appropriate ceiling tile above the unit position and insert the
replacement-ceiling tile. If there are two ceiling panels with your kit, make sure
that the deflector is facing the opposite direction to the other opening. This
prevents the intake and exhaust air streams from directly mixing. Attach the
hanging ducts from the ceiling panel to the collars on top of the unit and attach
with the supplied hose clamps. Split-system (SPLAC) models use a housing with
a single flange, which is attached to the condenser hot air exhaust. A single 12-
inch duct is attached to the flange and extended to a 2-ft by 2-ft replacement
ceiling tile, using the screw clamps.
d. Power Connection – Follow all safeguards as listed in this manual. For all units
that come with a factory-supplied plug, make sure that the voltage, amperage,
and receptacle type are consistent with the model specifications. For units 3.5-
tons and above a qualified electrician is required for connection of the 6-foot
pigtail lead on the recommended circuit for the specific model. For three-phase
units, it is important that the rotation of the evaporator fan (cold air supply) is
correct. Make sure the fan rotation is counter-clockwise in relation to the drive
motor. If it is going clockwise, switch two of the power leads. This should correct
the problem. Note: If the unit runs with the evaporator motor turning
backwards, the unit will overheat and either trip the high pressure
compressor switch or burn up the condenser motor.

e. Water Connection for Water-Cooled (SWAC) Models – Water-cooled units are
equipped with two brass female ½-inch pipe thread connections located on the
lower left corner of the back panel, except for 10-ton units which have 4 female
connections. Use a proper sized wrench to connect either hard piping or the
optional high-pressure line set. Apply Teflon tape to the thread for a good seal.
Water pressure should be limited to 150 PSI and should be between 40 and 85
degrees F. If the water supply is interrupted the unit will shut down and go into
alarm “AL” mode.
f. Flexible Line Set Connection for Split-System (SPLAC) Models – Split-
systems units are supplied with a 20-foot pre-charged self-sealing refrigerant line
set, which is used to connect the cold air evaporator to the condenser section.
Be sure not to kink the line set by making sharp bends, which will block the gas
flow. There are two types of coupling, which are located on the lower center
back panel of the unit sections. For units sized 1.5-ton and under there is a lever
connection into the evaporator and two female coupling for the condenser. For
units 2.5-ton and above there are 4 female couplings, two for the condenser and
two for the evaporator. For permanent application using the substituted rolled up
copper line set, a qualified technician should perform installation, avoiding any
kinks in the line set. The following steps should be followed for hook up: 1)
Remove the line set from the box and lay it out flat making sure that the
connections match the color codes on the units and that the lever type, if
equipped, has the lever on the top side. 2) To connect the coupling type fitting,
make sure that the female swivel and male threaded fittings are clean and free
from debris. Connect the female swivel to the male threaded fitting by holding
the line set in one hand while threading the couple on with the other hand. You
will have to apply pressure to the fitting to make the connection. Be sure not to
cross thread the fittings. Tighten the fitting with the appropriate wrench, until the
fitting just barely bottoms out on the male fitting for a snug, but not tight fit. Do
not over tighten the fittings!!! It is better to be a quarter-turn too loose than too
tight. 3) For units with the lever-type connection pull the lever back until it is
positioned in the up position. Hold the fitting in one hand and pull back on the
black plastic sleeve. While holding this sleeve back, gently push the connector
onto the male fitting on the evaporator. You may have to gently rock it to insure
that it is totally inserted into the coupling. Push the sleeve toward the unit. It
should go in completely. Gently pull on the line set to assure that it has engaged
properly. When you are confident that the sleeve is locked in place, push the
lever back to its closed position until it stops, completing your refrigeration
connection. Now insert the electrical fitting into the female opening just above
the refrigeration connections on the condenser and evaporator sections.
(Multiple disconnections may result in a loss of refrigerant.) 4) Attach the
electrical connection to the underside lip above the fittings, which provides power
to the condenser.
3. OPERATIONAL SAFEGUARDS
Read the following safeguards carefully before installing the unit:
a. Do not operate or install your KwiKool unit in a potentially explosive, combustible,
or corrosive gas atmosphere.
b. Keep your KwiKool unit away from flammable materials and other sources of
heat.
c. To avoid electrical shock keep your KwiKool unit away from direct contacts with
water and any liquids and do not touch your unit with wet hands.

d. To insure your KwiKool unit is stable, the floor on which the unit is to be place
should be level, free of vibration and strong enough to support the weight of your
KwiKool model.
e. Do not move the unit while it is running. Before moving the unit, first unplug the
unit from the power source. Then set the caster locks to the “Off” position,
freeing the casters to roll. Be sure to lock the casters by setting the caster lock to
the “On” position, when the desired position is achieved.
f. Do not tilt or overturn your unit, since this could damage the compressor.
g. Do not place objects on top of your unit.
h. Do not insert your hand or any other object into the cold air supply chutes.
i. Do not operate your KwiKool unit with its service doors open or removed.
j. Close supervision is necessary when the unit is used near children or pets.
k. Your KwiKool unit should not make any abnormal noises or vibrate while in
operation. If this should occur, turn the unit off and call KwiKool at 1-800-
594-5665.
4. UNIT OPERATION – Touch Pad Controls
a. Control Panel – The operation of the unit is controlled by a microprocessor.
The control board is located directly behind the touch pad control. Check the
power supply before unit operation. If a power failure occurs, the unit control
will return to the previous set point.
b. On/Off Button – Depressing this pad will turn the unit on or off each time the pad
is depressed. The unit has a three-minute short cycle protection time delay after
turning on the unit before the compressor startup occurs.
c. Mode Button – Depressing the fan mode button will cycle through the available
modes. The modes are: 1) “Fan” mode, causes the fan to run continuously,
without the compressor in operation. 2) “Cool” mode, causes the both the fan and
the compressor to operate, after the two-minute delay. 3) Heat (if equipped), both
fan and heat elements will operate. 4) Auto (if heat equipped) unit will auto
change between heat and cool.
d. Fan Button Single Speed Models – Models KPAC1011, KPAC1411, SAC2411
and SAC6043. Pressing this pad will cycle the fan from “auto fan” to “fan”, as
indicated by the display. The fan button can be overridden when the mode
switch is set to “fan”.
e. Fan Button for Cold-Air Supply – On 3-speed models pressing the fan button
will cycle the fan speed from “Low” to “Medium” to high to “Auto Speed”. “Auto
Speed” will automatically adjust the fan speed based on the current cooling
demand from the compressor load. For continuous cold air fan operation on
all units, press and hold down the fan button for 3 to 5 seconds, until the
display showing “auto” disappears. You can continue to press the fan
button to change the fan speed. Placing the unit in “Fan On” mode can
improve air circulation while retaining the appropriate cooling response.
f. F/C Button – Pressing this pad will cycle the display between Fahrenheit and
Celsius temperature measurement. Note: For ambient temperatures in excess of
99 degrees F., the display will flash “99”, indicating an ambient air temperature
exceeding 99 degrees.
g. Up (+) and Down (-) Arrow Buttons – Depressing these keys will change the
temperature set point. During normal operation the display shows the incoming
air temperature. When either arrow is pressed the display will change to the
setting temperature and the word “Set” will be shown on the display, indicating
target temperature set point. The display will revert back to ambient temperature

within a few seconds of releasing the arrow button. Unit capacity sizing is based
on maintaining a 72-degree F. temperature. For every degree below 72 degrees
F. the unit selected must have an additional 6,000 Btus of capacity for a 100
square foot server room. Please note, if the heat load of the room exceeds
the capacity of the unit, the unit will not shut off and may freeze up. If the
unit freezes up, raise the set point at least 2 degrees in order to allow the unit to
hit its set point and cycle off.
5. BUILT IN UNIT SAFEGUARDS
a. Compressor Protection Time Delay – An internal overload circuit to prevent
overheating protects the compressor. There is a two-minute time delay in the
control system to prevent short-cycling of the compressor. The delay is in effect
anytime the compressor is turned on, whether by the controls or resumption of
power after an outage. The display will flash the “F” of the C” during the timeout.
b. Fan Cycling – All KwiKool models, except water-cooled units, are equipped with
fan cycling, which provides limited coil freeze protection from low ambient
temperatures and reduces startup current. The condenser fan comes on as coil
heat load requires, but does not start with the compressor. The condenser fan
will cycle more frequently at lower ambient temperatures of the intake air (under
80 degrees F.)
c. High-Pressure Switch – The compressor is equipped with a high pressure shut
down switch. If the unit is subjected to ambient temperatures above its design or
if the unit has condenser ducting beyond its recommended length, the safety
switch will trip to protect the compressor from excessive head pressure damage.
Check for restrictions in the condenser ducts and make sure that the space
above the ceiling has sufficient air flow or cubic space to absorb the rejected
heat. After correcting the problem reset the high-pressure switch by opening the
service door and pressing the red button on top of the control box. You should
feel the switch click. It is located near the filter dryer on the small high-pressure
line. Close the service door and restart the unit.
d. Low-Pressure Switch – All KwiKool models has a low-pressure switch, except
for the KPAC models, which protects the compressor from low-pressure damage.
The low-pressure switch is located above the compressor inside the service door
with two yellow wires connected to it. This switch will trip when the intake
condenser air pressure drops below recommended specifications, which may be
due to a constrained airflow from the condenser intake.
e. Service Ports and Sight Glass – Service ports and sight glass are used for
convenient diagnosis of refrigerant pressures. For all models the service ports
are located inside the return air grill. For SAC air-cooled models the site glass is
inside the condenser intake. For water-cooled SWAC models they are inside the
back service door. For water-cooled SWAC and split-system SPLAC models the
sight glass is inside the service door. It is normal to observe bubbles in the
site glass and does not indicate a low refrigerant level.
6. APPLICATION SAFEGUARDS
a. Automatic Restart – The system will resume operation automatically
after a power interruption and returns to the previous settings.
b. Condensate Tank – When the condensate tank is full, an audible
alarm will sound, and the compressor will stop running and the control panel will

display “CF” to signify “Condensate Full”. When this occurs, turn the On/Off
switch to the off position and unplug the float jack and condensate drain line from
behind the unit and drain the tank. Replace the tank, plug in the float jack and
drain line and turn the On/Off switch to the on position. The unit will return to its
previous settings in two minutes. The condensate tank is normally used only for
short-term applications. Note: If you do not turn the unit to the off position,
the unit will continue to sound the alarm until the float jack plug is
reinserted.
c. Safety Alarm – If the unit alarm “AL” is displayed, the unit will
automatically shut down and an audible alarm will sound. The “AL” display may
indicate low or high condenser pressure, or a condensate pump failure. Call
KwiKool (1-800-594-5665) for technical assistance.
d. Condensate Pump – All KwiKool models, except KPAC models, come
standard with an internal high lift condensate pump with a 20-foot head pressure.
The pump collects the condensation that forms on the evaporator coil into its
one-quart reservoir, during normal cooling operation. If the unit is required to
operate continuously, it is recommended to run a ¼-inch condensate line from
the nipple on the back of the unit to the nearest drain. The line can be run up the
same path as the ducting, then across the ceiling to a drain, up to 150 feet away.
The jack plug, located in the same package with the owner’s manual, must be
plugged into the hole just above the ¼-inch nipple. The insertion of the jack plug
will deactivate the condensate alarm by sending a message to the unit that a
condensate line has been run to a drain.
7. APPLICATION REQUIREMENTS
a. Air Temperature Requirements – The environmental requirements of your
KwiKool unit at the installation site are 60 to 110 degrees F for the intake
condenser air. If the unit is operated in an environment above this range, the
high head pressure switch will trip, stopping the unit’s compressor, which must
be reset by pressing the red button on top of the switch. 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. If the intake air for the front duct is taken from outside the
building, the unit will cause the unit to cycle excessively at temperatures below
60 degrees F. For split-system models the condenser section must be placed in
an area with ambient air temperatures above 60 degrees F. or the unit will cycle
excessively and damage the fan cycling switch.
b. 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. Therefore, we recommend that you do not set the temperature set
point below 72 degrees F., unless you have excess cooling capacity, since
this may cause the unit’s coil to freeze up.
c. Condenser Intake/Exhaust Air Requirements – Two ducts attached to the
flanges on the top of the unit, are normally vented to a drop ceiling via the ceiling
kit. The rear top flange is for the condenser hot air exhaust and the front flange
is for the condenser intake air. The area above the ceiling must be open to the
rest of the floor or tied into duct, which leads to the outside. If the area above
the ceiling is sealed the pressure will back up into the unit and shut it
down, due to high head pressure. (See ceiling kit section c on page 4.)

d. Positioning of Unit – Do not place your KwiKool unit in direct sunlight, since this
will affect the efficiency. The unit should be positioned as close to the heat
generating equipment as possible with the front grill fully exposed. Do not block
the front of the unit.
e. Electrical Connection – Connect the plug to the proper power circuit and
breaker, based on unit specifications on the rear of your KwiKool unit. Connect
the power cable firmly into the socket. Disconnect the power cable by pulling the
plug, not on the wire. Do not use extension cords for connection to the unit,
unless the proper wire size is used with a length not to exceed 25 feet.
Improper extension cord use may damage the compressor or prevent the unit
from operating, due to a voltage drop. Make sure that the KwiKool unit is
connected to a dedicated circuit, since power surges from the compressor
could damage other equipment or trip the breaker.
f. Ducting Requirements – The KwiKool unitary models are designed for two
ducts to be run from the top of the unit to the drop ceiling above the unit. The
area above the ceiling must either be open to the rest of the floor or run
above-ceiling duct to an open area, using a double flange ceiling tile. If
there isn’t a sufficient space for the hot air exhaust to dissipate, the unit
will shut down on high head pressure. If above-ceiling ducting is used, verify
with KwiKool that the duct length is within the unit’s specifications. Also, any
perforated panels in the ceiling must be replaced or blocked with a solid
tile, since this will allow the heat in the ceiling to reenter the room being
cooled.
8. UNIT MAINTENANCE
a. Check Air Filters – The air filter is located inside the door on the lower front of
the unit. Inspect and replace air filters at least once a month. Replacements are
available upon request or at your local HVAC supply store. Call 1-800-
KWIKOOL (594-5665).
b. Fan Belts – Check condenser fan belts every 3 months on models so equipped,
models with 3.5-ton capacity and above. Follow the following steps:
1. Turn unit off and disconnect the power cord.
2. Check belt tension, no more than ½-inch of play, and belt wear.
3. Replace belts, if belt is glazed or worn.
4. Tighten loose belts with adjustable motor base.
c. Condensate Tank – If the condensate tank is used, drain water that has
collected in the unit tank. On KPAC models the tank is inside the inspection
door. All other models use an external tank.
9. UTILIZING YOUR KWIKOOL SYSTEM
In contract to conventional air conditioners, which circulate air conditioning capacity evenly to an
entire floor, the KwiKool units are designed for cooling an area with a high concentration of heat
load, usually from electrical or computer equipment. Understanding the capabilities of your unit
can help you avoid problems. For example, if you add heat-generating equipment to the room
after purchasing a KwiKool unit, you may be short of the necessary cooling capacity. Your
KwiKool unit offers an effective affordable solution for many applications. It can also provide
spot cooling for workers or process cooling within large space without the use of condenser
ducting, such as a warehouse factory, or production areas. If the unit 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 absorb the cool air very quickly. Your KwiKool Strategic Air Center 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.
10. TROUBLE SHOOTING GUIDE
a. Blank Display – Caused by power failure, tripped circuit breaker, or unit not plugged in.
b. Unit will not Start – Caused by:
1. Unit is timing out. Wait 3 minutes.
2. Tripped Breaker, Reset Breaker
3. Unit is in Off Mode. Put unit in "On" Mode.
4. Set point matches ambient air temperature.
c. Unit Off/Alarm Sounds & Panel Display Reads “CF”
1. Condensate Float Jack not installed.
2. Condensate Tank Full. Empty tank.
d. Unit Alarm Sounds & "AL" Displays
1. High Pressure switch activated. Reset switch is the red button inside access
panel.
2. Check condenser intake & exhaust duct for restricted air movement.
3. Check area above the ceiling for limited air movement. Provide additional path
for exhaust & intake air flows.
4. Pump drain line is restricted. Check water line for blockage.
e. Unit Will Not Cycle “Off”, Continuous Cold Air – The compressor never shuts off,
indicated by constant cold air discharge. This condition may cause the evaporator coil
to freeze up.
1. Temperature set point is set too low.
2. Improperly sized unit, insufficient capacity.
3. Excessive outside ambient air from outside. Close doors when building air
conditioning is shut down. Also, block perforated panels in ceiling, which may
cause heat to come back into the room.
f. Unit Runs Without Cooling – Compressor Will Not Start
1. Check circuit voltage. For 208/230-volt units, a circuit voltage of 208 may
prevent the compressor from starting, since the unit is set up to run at 230 volts.
Change voltage switch inside the inspection door to the 208-position.
2. If coil freezes, put unit in fan mode by holding down the fan button for 3 seconds,
raise temperature set point to allow unit to cycle on & off. Wait about 30 minutes
to the coil to unfreeze. The unit’s capacity may be undersized for the
application’s heat load.
3. A dirty intake filter on the front of the unit will block heat exchange across the
evaporator coil, which will prevent cooling.
4. Obstruction to the condenser air intake may cause the compressor to shut off on
high pressure. Check the airflow going into the top of the unit’s front flange from
the space above the ceiling or the air intake.
5. Unit’s control mode is set to “fan” only.
g. Trouble-Shooting Failure – If your trouble-shooting efforts fail, call KwiKool at 1-800-
594-5665 and ask for service support.
