II / Phase Monitor Components The KwiKool Phase Monitor is factory installed and is located inside the Control Box. The Phase Monitor can be accessed through the right side service door as you face the unit and removing the cover to the control box. e. f. g. b. a. c. h. a.

III / Assembly A. 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. B. 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. C.
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 system with its service doors open. J. If your KwiKool system makes abnormal noises or vibrations, call KwiKool at: 1-800-594-6556. VI / Installation A.
D. 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.
e. 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. G. 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.
D. Automatic Restart - 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. E. Condensate Pump & High Level Alarm - KPO 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 1/4” I.D.
unless you have excess cooling capacity beyond your heat load, since this may cause the unit’s evaporator coil to freeze up. C. Positioning of Unit - The unit should be positioned as close to the heat generating equipment as possible with the return air duct directly in the area of highest heat load. Do not block the return air duct of the unit, since this will cause low performance and or evaporator coil freezing.
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.
Fault Possible Cause Possible Solution Power is supplied but control is blank. Low Voltage circuit is not engaged. On 12-ton models turn on built in breaker, all models verify incoming power to contactor, reset switch on low voltage transformer. Control displays and operates but unit is not on when selector switch is in the ON position. This condition only occurs in systems without a phase monitor, incoming power is not correct. Verify incoming power to contactor, correct as needed.
XII / KPO Advanced Troubleshooting Guide Fault Possible Cause Possible Solution Mechanical system has detected high water level in the condensate pump. Inspect condensate pump for overflow and proper operation call KwiKool at: 1-800594-5665, check condensate line for clog or crimping. Resets automatically upon correction. Mechanical system has detected high pressure.
Fault Possible Cause Possible Solution Evaporator coil is freezing. Low or restricted air flow. Undersized capacity, unit constantly on, unable to achieve set point. Low return air temperature out of factory specifications. Service door open or off, mechanical system malfunction. Review duct engineering, direct return air duct to area of highest heat load, replace air filters, adjust set point to allow unit to cycle, add more KwiKool units or capacity, close service compartment door.
