In contrast to conventional air conditioners, which circulate air conditioning capacity evenly to a space. KwiKool systems are used for cooling an area with a high concentra- tion of heat load, such as from electrical or computer equipment. Understanding the ca- pabilities of the KwiKool can help the operator avoid problems. -

SECTION II - INSTALLATION AND ASSEMBLY A. PREVIEW THE INSTALLATION SITE WARNING In COOL Mode, DO NOT place the KPOXX in the space that is being cooled unless utilizing the op- tional condenser return air panels. The KPO is gen- erally designed to be outside the conditioned space and ducted in. -
Page 9: Power Connection
1. The supply air works best directed to heat load equipment inlets or directly on the area to be cooled. 2. The KPO series requires ducts to direct the cooling or heating into the conditioned space. This is done with 12-inch duct on KPO5 & KPO12 and 20-inch duct on KPO25. - Page 10 Customers using this unit only to blow conditioned air and that are not trying to con- dition a space may not need to connect a return air duct. However, the KPO series requires a minimum amount of duct to operate (see specifications). If operating this unit with no supply or return ducting, reduce the return air by at least 50%.
- Page 11 CAUTION Allowing the KPO to operate without evaporator side duct or without reducing the return air could cause condensate water leakage, diminished tem- perature difference and/ or evaporator motor fail- ure. PRUDENCE Permettre au KPO de fonctionner sans conduit côté évaporateur ou sans réduire le retour d'air pourrait entraîner une fuite d'eau de condensation, une dim- inution de la différence de température et/ou une...

Page 12: Section Iii Operational Safeguards
SECTION III - OPERATIONAL SAFEGUARDS Read the following warnings and safeguards carefully before installing or moving the KwiKool. WARNING Do not operate or install the KwiKool unit in a po- tentially explosive, combustible, or corrosive gas atmosphere. AVERTISSEMENT N'utilisez pas et n'installez pas l'unité KwiKool dans une atmosphère de gaz potentiellement explosive,... - Page 13 AVERTISSEMENT Pour éviter les brûlures et les dommages causés par le feu, gardez le système KwiKool à l'écart des matériaux inflammables et des flammes nues. WARNING Do not move the system while it is operating. Be- fore moving the system, first turn to OFF then un- plug the system from the power source.
- Page 14 N'utilisez pas le système de la série KPO avec ses portes de service ouvertes, car cela pourrait affec- ter la circulation de l'air dans le système. If the KPO system makes abnormal noises or vibrations, call KwiKool at 1-800-594-5665 (1-800-KWIKOOL).

SECTION IV - UNIT OPERATION A. STARTUP 1. Apply electrical power. When power is supplied to the unit, the controller will become operational. All KPO systems are equipped with an integral power/ phase monitor. 2. KPO12 and KPO25 users will have to place the unit’s built-in breaker to the ON posi- tion to engage the controller. -

camlock vert, sinon des dommages pourraient en résulter. b) Power the unit back up, wait for 30 seconds and then proceed to the next step. If the fault fails to clear after changing the phase, turn the power off at the source, return the wires back to the original configuration and refer to Section XI, Trou- bleshooting. -
Page 17: Operating Modes
ON/OFF 1. Press the icon. A short press on this button turns the system on or off and the system operates in the last parameter that was entered in operating Mode. DOWN 2. A short press on the arrows raises or lowers the set point in the cur- rent operational mode. -
Page 18: Cool Mode
NOTE Fire rated or high temperature duct is NOT required to use with the KPO series in HEAT mode. The heat capacity rating for KPO systems is as follows: KPO25 is 60 or 48 KW, KPO12 is 30 or 24 KW, and KPO5 is 15 or 12 KW. - Page 19 NOTE The heat function on KwiKool KPO systems will not require a time delay or compressor operation; therefore, there is no delay in starting and no need to manage condensate water or condenser air dis- charge. OPERATING MODE, AUTO COOL/ HEAT (optional)
-
Page 20: Built In Safeguards
Protects the KwiKool while in COOL mode from potential damage by delaying the com- pressor from starting before the pressures in the mechanical system equalize. The Time Delay always activates when the KwiKool cycles off or is turned off, or if power is lost and then restored. -
Page 21: Service Ports
Used as a diagnostic tool by qualified personal. F. AUTOMATIC RESTART In the event of a power loss, the KwiKool resumes operation when the power is restored if in the ON position. All operational functions are saved in the memory of the control. -
Page 22: Vfd-Variable Frequency Drive
SECTION VI - APPLICATION REQUIREMENTS A. AIR TEMPERATURE REQUIREMENTS COOL MODE The environmental requirements of the KwiKool unit at the installation site are 0 to 110 F for the condenser make up air located on each side of the unit. Standard KwiKool KPO models are not designed to operate at temperatures below 60 F. -
Page 23: Positioning Of Unit
The unit should be positioned as close to the space to be conditioned as possible with the return air duct directly downstream of the highest load. Place the KwiKool system on a level surface with casters locked to prevent unintended movement of the system and to ensure proper condensate water flow. -
Page 24: Section Vii Maintenance
SECTION VII - MAINTENANCE A. AIR FILTERS The KwiKool comes from the factory with filters installed on the evaporator inlet to pre- vent dust and debris from entering the system and circulating in the conditioned space. Factory installed filters are a disposable type and must be periodically checked and re- placed based on the air quality of the conditioned space. -

CAUTION Failure to maintain the drive belts will cause low performance, high-pressure trip or, in extreme cases, damage to the blower/motor in the event of a belt breaking. DO NOT ADJUST THE DRIVE PULLEY. ADJUST THE MOTOR BASE FOR BELT TENSIONING. DO NOT OVERTIGHTEN BELT. -
