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. Ceiling Kit (Optional Accessory) - The ceiling kit is comprised of flanges with foam tape, fasteners, two (2) eight foot lengths of flexible duct, duct clamps, and one 24”X24” replacement ceiling tile for KIB 1411 and KIB1811. All other KIB models use two (2) 24”X24” replacement ceiling tiles. Follow these installation steps: 1. Align the holes of the flange to the holes located on the top of the unit. Attach to the top of the KwiKool unit using the factory supplied fasteners. 2.
D. 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.
IV / System Operation A. Apply Electrical Power - Once power is engaged by plugging in your system and/or switching the breaker to the on position, your KwiKool display will come alive and show the current room temperature. The unit is set to OFF and the fan is set to the default position. A 2 minute time delay starts, indicated by a flashing F on the display. If you are not seeing anything on the display, refer to the Troubleshooting Guide section of this manual. B.
4. Fan - Pressing the fan button has different operations depending on the model. a. Single Speed Models - KIB 2411, KIB6023, KIB6043, **KIB12023, **KIB12043. On the single speed models, pressing the fan key cycles the supply air fan between auto fan and fan on. When the system is in auto fan, the supply air fan only operates when the compressor is running. When the fan is set to on, the fan runs continuously as long as the unit is in the ON position. The fan speed window will be blank on these models. b.
2. COOL - If the unit was previously set to the cooling mode (cool) then “cool” will be displayed. If the compressor is running, the ”cool” on the display will be flashing. If your unit has been sitting for over 2 minutes, this should happen immediately upon turning the unit on, unless your set point is lower than the current room temperature. In this case your unit is ready to automatically turn on once the temperature rises above the set point.
F. Condensate Pump & High Level Alarm - All KIB Iceberg models are factory equipped with an internal high lift condensate pump. KwiKool condensate pumps are able to pump the condensation either to the factory supplied condensate bottle, or to a drain or other location as required by the application. The internal pump is rated at 20 foot of head pressure. This means it can pump water to a maximum of 20 feet vertically.
C. Positioning of Unit - Do not place your KwiKool unit in direct sunlight, The unit should be positioned so that the output of the unit can be focused as close to the heat generating equipment as possible with the front grill fully exposed. Do not block the front of the unit, since this will cause a restriction in the airflow and can cause low performance and/or evaporator coil freezing. VII / Maintenance A.
IX / Fault Codes Your KwiKool Iceberg System incorporates a self-diagnostic system that sounds an audible alarm, stops your system and displays a fault code to indicate the nature of the problem on the display panel. See the troubleshooting guide later in this manual for further information.
Fault Possible Cause Possible Solution Unit Displays HP, Audio alarm is sounding during start up or while operating. Microprocessor board has detected high pressure. The High Pressure switch is tripped. High pressure is normally caused by reduced condenser air flow. Check for restriction in ducting. Check for condenser air system ventilation (See Section II. C. 4). Check condenser motors and/or blowers for proper operation. On KIB12023 or KIB12043 check VFD (motor drive) for trip. Reset if necessary.
Fault Possible Cause Possible Solution System is ON but the microprocessor board resets the time delay (flashing F or C) when the compressor attempts to start. Microprocessor board detects voltage drop below operating parameters. Confirm the integrity of your source power, check for proper wire size and length of power extension cable. Be sure the circuit is dedicated to only the operation of your KwiKool.
Fault Possible Cause Possible Solution Condensate is not pumping. Water is below pumping level, external line restricted, line installed with too high of lift. Reservoir fills, and then pumps. Check for line crimping or restrictions and proper line run height. Refer to the user guide Section 5: Built in Safeguards. 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.
Appendix Part A: Systems Equipped with a Phase Monitor - Page: 17-18 Part B: Special Section for KIB120 Systems - Page: 19-20 Page 16
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. LED Lights Used to indicate failure cause. b. Line Side Incoming voltage from the contractor. c. Load Side Outgoing voltage from the contractor d. Voltage Adjustment Knob Set knob to match correct unit voltage. e.
B: Special Section for KIB120 Systems A. Compressor Priority Switch - For KIB12023 and KIB12043. 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 KIB120 is equipped with a Compressor Priority Switch located on the top of the control box in the evaporator access compartment.
E. Conditioned Air Supply Drive Belts - Your KwiKool KIB120 models moves air over the evaporator coil to remove heat and moisture from the conditioned space by way of a motor attached to 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, coil freezing or in extreme cases damage to the blower/motor in the event of a belt breaking.
