Read the following safeguards carefully before installing your KwiKool:

systems do not require a ceiling kit or duct to operate in your conditioned space, a
chilled water loop or cooling tower supplies and returns water to cool the condenser on
your KwiKool. Contact a building engineer or HVAC contractor to verify the viability of
connecting to a re-circulation system. Tap water is generally no used for operating your
KWIB due to the potential large volume of water needed. A constant flow of water is
needed between 35 psi and 150 psi, not to exceed 85 degrees F and above 40
degrees F. Connect supply water to the 1/2” or 3/4” NPT female connector labeled
Water Inlet on the back of your KWIB, and connect the return water line to the 1/2” or
3/4”, NPT female connector labeled Water Outlet. KWIB120 systems have 2 water
inlets and 2 water outlets. Use a back up wrench on the female connectors supplied on
your KWIB when connecting the water lines to prevent the internal copper tube from
twisting, apply Telfon tape to the threads of the male connectors. KWIB must have a
supply of water to operate or the system will shut down, sound an alarm, and display
the HP alarm on the control panel. This will protect the mechanical system from
damage. The manual reset is located in the filter compartment, labeled “HP reset”,
Push in to reset after the water supply is restored.
**Note: if during operation of your unit you notice a loud clanging or hammering should,
this is known as water hammer and has nothing to do with the unit itself but the location
of the water source. Installation or a water hammer suppressor such as a Watts or
Sioux Chief water hammer arrester will solve this issue.
Visit www.KwiKool.com for more information and a complete set up guide.
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
receptacle 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 the voltage incoming to the correct setting to avoid
potential operational issues. Read the Operational Safeguard section before applying
electrical power.
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.
