Connecting the Casters - Lift the unit carefully with a forklift using the built in fork
pockets; DO NOT TILT the unit to bolt the casters to the base. Use all bolts and nuts
included, 4 for each caster and tighten well.
Install Flanges - All flanges are pre-drilled and measured to fit on your KPO. Line up
the holes in the flanges to the threaded female insert on the cabinet and install included
fasteners, tighten well. Loose flanges will leak air and can diminish performance.
Installation Site - Preview your installation site, DO NOT place the KPO in the space
that you are cooling. Your KPO is designed to be placed outside the conditioned space
and ducted in. Before moving your KPO into place verity the following. The direction you
would like the supply and return air to go (cooling),the direction you would like the hot air
exhaust to go (heat removal),where will the condenser make-up air coming form,where
is your power supply located and where is the condensate water pumping too? Position
the unit based on these guidelines for best results. NOTE: Leave at least 5’ of space
open around the make-up air inlets for the condenser to ensure proper operation.

III / Power Connections
Verify the source power, phase and breaker size is compatible with the units serial plate
information, if you are not sure contact a licensed electrician. The KPO 5-ton comes from
the factory with an 8’ power cable sized to fit the electrical specifications of the units’
electrical requirement and has no male receptacle attached. The KPO 12-ton comes without
a power cable and has 4 male cam lock connectors ready to receive the corresponding
female cam locks, the female cam locks, or complete cord line set can be purchased
separately with the proper cable size attached from the factory in various lengths. Users of
208/320 volt units will be required to set a switch located in the units’ control compartment
to select incoming voltage: the default selection from the factory is 208 volt. 230 volt
requires the switch to be changed.
IV / Operational Safeguards
Read the following safeguards carefully before installing your KPO KwiKool:
C.
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. Do not touch your system with wet hands.
To insure your KwiKool system is stable, the ground on which the system is to be placed
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 to
OFF then unplug the system from the power source. Then unlock the casters.

V / Installation
Install Condensate Line - The KPO series comes equipped with a high lift conden-
sate pump, the connection is a 1/4” outer diameter barbed fitting located on the left
side upper portion of the condenser inlet on the 12-ton models as you are facing the
control panel and next to the power cable connection to the cabinet on the 5-ton
models. It is important to connect the condensate line prior to hooking up the electrical
power as the condensate pump is live when power is engaged. Collected water in the
pumps reservoir could be ejected when powered up.
Install Cold-Air Supply Flex Duct - The KPO line requires a duct to direct the
cooling into the conditioned space, this is done with a 12” diameter duct. As you face
the unit opposite the control end, the supply is on your right side. Clamp supply ducting
onto the 12” flange(s), and route the duct to your desired location. The supply air
works best directed to the inlets of your equipment or directly on the area to be cooled.
Install Cold-Air Return Flex Duct - Your KPO portable air conditioner works at its
best when the return air return is directly in the area of highest heat load, this place-
ment allows the unit to return the heat load directly to the evaporator and not to linger
in the conditioned space. This is also done with 12” diameter duct. As you face the unit
opposite the control end, the return is on your left side. Clamp return ducting onto the
12” flange(s), and route the duct to your desired location. NOTE: The return air duct is
pulling in air and can try to collapse while operating, avoid this condition by pulling
all of the slack out of the duct and anchoring it to a fixed object. Duct collapse is the
number one cause of evaporator coil freeze or low performance. *NOTE: KPO
models utilize high static blowers. The KPO systems must have a minimum of 25’
ducting for each inlet and outlet. KPO 12-ton must have 100 total feet of duct
(minimum 2 ducts). KPO 5-ton must have 50’ of total ducting (minimum 1 duct). For
example if using a KPO 12-ton you need 100’ of duct. You can use 4-25’ pieces on
any outlet. If you are not sure about your application, call us at: 1-800-KWIKOOL.
**NOTE: Customers using this unit only to blow cold air and that are not trying to
cool a space may not need to connect the return air duct. However the KPO line
requires a minimum amount of duct to operate. If you are operating this unit with no
ducting, you will need to damper the return air by at least 50%. Allowing the KPO to
operate without duct or without dampening the return air could cause condensate
water leakage, diminished temperature difference, and/or evaporator motor malfunc-
tion.
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.

Install Flex Duct (hot-air discharge) - You will need to direct the hot air discharge
away from your conditioned space and away from the condenser air intakes. This is
especially true when the KPO is used in a confined space or an indoor closed space.
This is completed with a 20“ diameter duct for the 12-ton and a 12” diameter duct for
the 5-ton. Clamp the duct onto the flange on the control side of the KPO and route to
your desired location (Visit www.kwikool.com for specific model specifications on
maximum duct lenght). NOTE: It may not be necessary to connect a hot-air discharge
duct if you are using the KPO outdoors and ducting the cooling into a space. When
used indoors or in a confined space and the hot air exhaust is ducted out, the KPO
must have a supply of make-up air for the condenser. The condenser make-up air
cannot be ducted into the KPO, and has to come from the surrounding space. Make
sure you have adequate fresh air supply or the unit will shut down to protect the
compressor from catastrophic failure.
Apply Electrical Power - When power is supplied to the unit, the controller will
become operational. KPO 12-ton users will have to place the units built in breaker to the
ON position to engage the controller. For units equipped with a Phase Monitor (all 12-ton
KPOs and KPO 5-tons 3 Phase models), the unit will display a red light alarm for 5
seconds, then clear when the microprocessor in the Phase Monitor “boots up”, this is a
normal condition. For units with a Phase Monitor, the most common reason the fault light
will not clear on initial start up is incorrect phasing. This condition is easily corrected. If
the red light fails to clear in 5 seconds a qualified personal may turn the source power off
and exchange any of the 3 line voltage wires with the other. DO NOT SWAP THE
GREEN WIRE. Power the unit back up and wait for the fault red light to clear for 5
seconds and then proceed to the next step. If the fault light fails to clear after changing
the phase, turn the power off at the source, return the wires back to the original
configuration and refer to the Troubleshooting Guide (section IX) of this manual.
Set your Controller - The controller of your KPO is factory set to start cooling above
72 degrees F and will be displaying the current room temperature; it is in cooling mode
and is set to come on within a 2 degrees temperature differential. If it is necessary to
alter these settings, the set routine is as follows:
E.
D.
F.
Page 7
Press set. F is displayed, use the up or down arrow to choose Celsius and
Fahrenheit, the letter C is then displayed.
Press set again, the current set point is displayed, use the up or down arrow to
change the temperature that the unit will cycle on or off at. NOTE: Lowering or
raising this temperature setting will not change the actual temperature of the supply
air, for best results always set the unit to a realistic temperature that it can maintain.
Press set again, the number 2 is displayed, this is the temperature differential,
changing this setting up or down is not recommended and only varies the range that
the temperature must be when cycling, and under some conditions may not allow the
unit to cycle on at all if adjusted out of the factory range.
Pressing set again, and C1 displays do not adjust this setting, this is the mode
setting and moving the control from this setting will place the unit in H1 which is
heat mode and not the abbreviation for the word HIGH and not used or available
in KPO models. Your KPO will not operate in this mode. H1 DOES NOT SIGNIFY
HI..IT IS HEAT 1 - THIS MUST BE SET TO C1.

Press set again, the unit displays the room temperature. This is the default display
and the control will always reset to this display automatically.
This completes the “set” cycle routine.

Time Delay - Protects your KwiKool from potential damage by delaying the compres-
sor from starting before the pressures in the mechanical system equalizes. Always
activates when your KwiKool cycles off, is turned off, or power is lost and then
restored.
High Pressure Alarm - 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 with
no fault light. To resume operation the system requires a manual reset after corrective
action is taken, the reset switch is located in the service door access on the compres-
sor discharge line. Push in to reset, if activated you will feel a click.
Low Pressure Alarm - Protects your KwiKool from potential damage to the
mechanical system by shutting down and alerting operators of the condition. This safety
activates when pressure below 20 PSI are detected in the mechanical system. Your unit
will sound an audible alarm only with no fault light. Call KwiKool at 1-800-594-5665 if
the alarm is present on start up. Automatic reset upon correction of the low pressure
condition.

Turn ON the System - Using the ON/OFF selector switch select to ON. The
evaporator fan starts and a 3 minute delay activates. This prevents the compressor
short cycling. After the time delay reaches 3 minutes the compressor starts and cooling
will begin. After the system has built up enough pressure the hot air exhaust fan will
start to ramp up, it is normal for this fan to delay in starting and also normal for it to
slow down and speed up downing the operating process. NOTE: The evaporator fan is
on continuously when the selector switch is in the ON position.
Cycling Off - After the system has reached its set point it will automatically cycle off
or you may choose to turn the system OFF by moving the selector switch to the OFF
position. If the unit cycles off or is turned off, the 3 minutes time delay will always
activate when the system calls for cooling. When cycling off by making the set point,
the evaporator fan stays on and cooling will begin automatically when the temperature
rises above the set point. Turning the system OFF manually will turn the evaporator fan
off and not allow the system to restart until the selector switch is set to ON and the
return air temperature is above the set point.
Installation Site - Preview your installation site, DO NOT place the KPO in the
space that you are cooling. Your KPO is designed to be placed outside the conditioned
space and ducted in. Before moving your KPO into place verity the following. The
direction you would like the supply and return air to go (cooling),the direction you
would like the hot air exhaust to go (heat removal),where will the condenser make-up
air coming form,where is your power supply located and where is the condensate
water pumping too?Position the unit based on these guidelines for best results. NOTE:
Leave at least 5’ of space open around the make-up air inlets for the condenser to
ensure proper operation.
