In contrast to conventional air conditioners, which circulate air conditioning capacity evenly
to an entire floor, KwiKool systems are generally used for cooling an area with a high
concentration of heat load, usually from electrical or computer equipment. Understanding
the capabilities of your KwiKool can help you avoid problems. 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 production areas. If the system is used in this manner,
unless you have excess cooling capacity beyond your heat load, since this may
cause the unit’s evaporator coil to freeze up.
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. Place your KwiKool system on a level surface to ensure proper
condensate water flow and be sure the surface is able to support the weight of your
KwiKool.

IX / Utilizing your KwiKool System
VIII / Maintenance
Air Filters - Your KwiKool 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 perfor-
mance. The air filters are located in the supply air return; remove the return air panel by
turning the slotted lock fastener to the horizontal position and lift up panel to replace
the filters.
Condenser Drive Belt (KPO 12-ton only) - Your KwiKool moves air over the
condenser coil to remove heat from the conditioned space by way of a motor that
drives 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, high pressure trip or in extreme
cases damage to the blower/motor in event of a belt breaking. Located in the
condenser access compartment on the control end of your KPO, release the 2 slotted
fasteners to give you access to the condenser belts and motor. NOTE: Adjust the
tension on the belts by adjusting the mother base. DO NOT ADJUST THE DRIVE
PULLEY.
Service Ports - Located in the service access door on the left side as you face the
control. This gives service personal a connection point for servicing gauges to monitor
the operating pressures of your KwiKool.
Sight Glass- Located in the condenser access compartment on the control side of
your KPO, 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.
