II / Assembly and Installation A. Air Chutes (standard equipped) - 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, equipped. B. Condensate Tank - The system comes standard with an internal 3-gallon condensate tank.
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. Attach the duct to the flange on the replacement ceiling panel; secure the duct to the flange using the supplied clamps. 3. Install the replacement ceiling panel in the ceiling grid with the duct attached, connect the open end of the duct to the flange on your KwiKool and secure with supplied clamps.
III / Operational Safeguards Read the following safeguards carefully before installing your KwiKool: A. Do not operate or install your KwiKool unit in a potentially explosive, combustible, or corrosive gas atmosphere. B. Keep your KwiKool system away from flammable materials and open flame. 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.
Display Shows - Current Temperature, Set Temperature, or Alarm Codes F Display Shows - Unit Mode Cool / Fan Cool FAN Display Shows - Fan Mode Fan OFF + - 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. All settings selected are stored in the microprocessor board even if the power is lost including the ON/OFF selection.
b. The lowest set point temperature available for your KwiKool is 60 degrees F, and the highest setting is 95 degrees F. The control will not allow adjustments beyond these ranges. C. System Operation 1. Turn On Your KwiKool System - Pressing the ON/OFF button once on your control panel will put your unit in the ON position and “ON” will be displayed on the right side of your display as well as the previously chosen mode. 2.
D. Condensate Tank & High Level Alarm - All KPAC II models come standard with an internal condensate tank. The tank is equipped with an overflow safety cut-off. When the tank is full, the safety will automatically shut down your unit, sound an audible alarm and display a fault code (CF) this prevents accidental flooding of the conditioned space. To continue operation when bottle is filled, see section II:B. E.
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.
Fault Possible Cause Possible Solution Unit Displays AL and 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 V:B). Check condenser motors and/or blowers for proper operation. High pressure is a manual reset type.
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 is installed to specification, remove or add duct as needed, check air filter for blockage. Evaporator coil is freezing Low or restricted air flow. Undersized capacity, unit constantly on, unable to achieve set point.
