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 KPHP1811 and KPHP2211. 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.
B. Control Panel - The control panel display shows the current operational status of the unit. Display Shows - Current Temperature, Set Temperature, or Alarm Codes F Display Shows - Unit Mode Cool / Fan Cool OFF FAN Display Shows - Fan Mode Fan + - Display Shows - On / Off Display Shows - Fan Speed (except single speed) 1. ON/OFF Button - Pressing this button on your control panel engages or shuts down your KwiKool system.
NOTE: Operations of KPHP systems will not have control of the supply air fan when in Heat Mode, the supply air is controlled by a pressure switch to optimize the systems operation and this switch overrides the microprocessor selection. It is normal for the supply air fan to delay in starting and to cycle on and off in the Heat Mode. 5. Up (+) and Down (-) Arrow Buttons - Raises or lowers the desired set tempera- ture.
turning the unit on, unless your set point is higher than the current room temperature. In this case your unit is ready to automatically turn on once the temperature drops below the set point. If the unit was recently turned off or the unit turned itself off because it reached the set point, the compressor will not turn on until the system waits for approximately 2 minutes. This prevents the compressor from being damaged do to a condition called short cycling.
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. Each pump is equipped with an overflow safety cut-off that automatically shuts your KPHP unit down, sounds an audible alarm and displays a fault code (CP). This prevents accidental flooding of the conditioned space. G.
D. 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 load source 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, can cause low performance and other operational issues discussed in the troubleshooting section.
X / KPHP 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 LP, Audio alarm is sounding during start up or while operating. Microprocessor board has detected low pressure. This alarm might cycle on and off. Check air filter and replace if dirty. Make sure nothing is blocking the filter inlet. Check for icing on coil. Resets automatically when fault condition is corrected. Call 1-800-KwiKool if condition continues. Unit Displays A1, Audio alarm is sounding during start up.
Fault Possible Cause Possible Solution System trips breaker on start up Incoming power is incorrect, breaker is undersized or faulty, and/or extension power cable is too long and or undersized. Verify the circuit and power cable is within the systems specifications, consult with your electrician or call 1-800-KwiKool for guidance.
Fault Possible Cause Possible Solution Chatter or hum is heard from the control box while the system is operating. Incoming source power is poor or low voltage component is faulty. Check for proper voltage selection on 208/230 volt units, remove excess or undersized power cable, and check incoming power. Call 1-800-KwiKool. 99 Flashes on display Ambient room temperature over 99 degrees F. Unit is working properly. Lowering of room temperature will rectify the flashing.
