I / Unit Components Page 3
II / Assembly and Installation A. Air Chutes (If equipped or as an optional accessory) - Install supply air flanges to the front of your KwiKool unit above the control panel. (See instructions in the air chute kit for specific procedures). Air Chutes - Conditioned air supply, if equipped or as an optional accessory. B. Condensate Tank - KwiKool systems come standard with an external 5-gallon condensate tank.
C. Water Connection for Water-Cooled (KWIB) Models - KWIBXX 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.
C. To avoid electrical shock keep your KwiKool system away from direct contacts with water and any liquids and do not touch your system with wet hands. D. To insure your KwiKool system is stable, the floor on which the system 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 system while it is operating. Before moving the system, first turn system to OFF then unplug the system from the power source. Then unlock casters. F.
1. ON/OFF Button - Pressing this button on your control panel engages or shuts down your KwiKool system. All settings selected are stored in the microprocessor board even if the power is lost including the ON/OFF selection. Refer to the Troubleshooting Guide section of this manual if your KwiKool is alerting an alarm after selecting ON. 2. MODE Button - Depressing the MODE button selects your choice of operations. Cool, for cooling with compressor operation.
NOTES: a. Lowering or raising the set point will not change the temperature of the supply air. For best results always adjust the set point to a temperature your KwiKool can cycle on and off at to avoid operational issues such as freezing or rapid discharge fan cycling, KwiKool systems are designed to maintain the set point when sized properly and constant operation without achieving the set point may shorten the expected operational life of your system. b.
C. High-Pressure Switch and Alarm - Protects your Iceberg Series unit from potential damage to the mechanical system by shutting down, sounding an audible alarm and displaying a fault code (HP) when the system pressure exceeds safe operating conditions. The high pressure switch is a manual reset switch and must be reset after the switch is activated and the condition causing the trip is corrected. D.
VI / Application Requirements A. Water Supply Temperature Requirements - The supply water temperature to your KwiKool unit at the installation site should be from 40 to 85 degrees F to the condenser supply water inlet located on the back of your KWIB Iceberg. If the water supply is above 85 degrees F the high pressure switch may trip, stopping the unit’s compressor. You also may notice diminished performance. The High Pressure Switch type is a manual reset.
VIII / Utilizing your KwiKool System In contrast to conventional air conditioners, which circulate air conditioning capacity evenly to an entire floor, KwiKool systems are designed 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. For example, if you add heat-generating equipment to the room after purchasing a KwiKool system, you may be short of the necessary cooling capacity.
X / KIB Troubleshooting Guide Fault Possible Cause Possible Solution Unit displays CF, Audio alarm fails to clear on start up or while operating External Condensate Tank is full. Condensate bypass jack or condensate float switch jack is not installed or not positioned correctly. Water level switch is engaged Empty External Tank (if using). Make sure thank is upright and level. Unplug bypass plug or tank plug and reinstall to assure good connections.
Fault Possible Cause Possible Solution Unit Displays A1, Audio alarm is sounding during start up. Phase Monitor (if equipped) has detected incoming power issue on equipped systems. See Troubleshooting Guide for systems equipped with a phase monitor (Appendix Part B). Audio alarm fails to clear on start up or while operating, unit displays FP. Microprocessor has detected freezing on the evaporator coil if the system has a factory installed freeze sensor.
Fault Possible Cause Possible Solution Supply air flow is limited, and Supply or return air is or water is dripping from the blocked or restricted, and or front of the system the evaporator coil is freezing. Verify that supply and return air are not blocked and duct work (if used) is installed to specification, remove or add duct as needed, check air filter for blockage. KWIB120xx users check supply air fan for correct rotation, refer to Appendix B. Condensate is not pumping.
Appendix Part A: Systems Equipped with a Phase Monitor - Page: 16-17 Part B: Special Section for KWIB120 Systems - Page: 18-19 Page 15
A: Systems Equipped with a Standard Phase Monitor Fault Possible Cause Possible Solution Unit displays A1 Audio alarm sounding during start up, phase monitor displays, lock out “Front Fault” red light Phase monitor detects reverse phasing, lost phase or improper power incoming. Exchange any line voltage wire with the other, verify incoming power. Auto reset upon correction. Unit displays A1, Audio alarm is sounding during start up, phase monitor displays, lock out “Front Fault” low volt red light.
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.

B: Special Section for KWIB120 Systems A. Compressor Priority Switch - For KWIB12023 and KWIB12043. These KwiKool models have 2 compressors and refrigerant circuits that operate independently of each other and are staged to come on at different intervals as needed for cooling. Your KwiKool KWIB120 is equipped with a Compressor Priority Switch located on the top of the control box in the evaporator access compartment.
