II. Incoming Inspection Kooltronic Air Conditioners are designed, built and packaged to withstand the shock and vibration normally associated with shipment by common carriers. Occasionally improper handling during shipping causes damage. Such handling could include unbanding of palletized shipments, failing to respect "This Side Up" arrows, rough handling, falling off conveyors, excessive vibration, crushing, etc. Therefore, a thorough inspection should be done upon receipt of all shipments.
IV. Product Identification and Labels Each Kooltronic Air Conditioner includes an identification label. This label provides: ➀ ➁ ➂ ➃ ➄ ➅ ➆ ➇ Model Number Serial Number Electrical power characteristics Maximum and minimum ambient operating temperatures Cooling capacity Type and amount of refrigerant required for recharging Design Pressure Underwriters Laboratories Inc. Listed or Recognized Marks and NEMA ratings We recommend you copy this information from your unit. Air Conditioner MODEL NO. SERIAL NO.
V. Principles of Operation COOL AIR TO ENCLOSURE CONDENSER OUTLET (Heated Ambient Air Out) (2 Places) HEATED AIR FROM ENCLOSURE CONDENSER HEAT EXCHANGER EVAPORATOR HEAT EXCHANGER P21 COMPRESSOR CONDENSER AIR INLET (Ambient Air In) Kooltronic Air Conditioners are required when the equipment operating temperature must be kept near or lower than the ambient room temperature, and/or the cabinet must be sealed from dust, fumes, oil, corrosives and other contaminants.
The heater kit consists of a heater, a heat control thermostat and a heater limiter. The heater control thermostat is a bimetal disk with a fixed set point of 60°F. When the entering evaporator air temperature rises above 60°F the heater shuts off, and when the evaporator air temperature falls below 40°F the heater will engage. The contact points of the alarm thermostat are normally closed.
VII. Specific Model Data Mounting The Kooltronic Special Purpose Air Conditioners K_NA4C3P21R have been engineered to be installed easily. These units utilize double layer gaskets. The first gasket layer is placed on the outside perimeter of the front panel that is sealed against the customer enclosure. The second layer is placed on the two cutouts in the front panel. The first gasket layer will allow a small amount of water between the two layers.

VIII. Maintenance Kooltronic Water-Cooled Air Conditioners require no maintenance. Air-Cooled Air Conditioners are designed to require only the routine cleaning of air filters to assure unimpeded airflow through the condenser heat exchanger. It is not possible to recommend specific filter cleaning intervals since the level and the nature of airborne particulate matter differs widely with each installation.
B. Blowers The design life of the blowers used in all Kooltronic Air Conditioners is substantially in excess of 20,000 hours. All Kooltronic condenser and evaporator blowers are equipped with automatic-reset thermal overload protectors. CAUTION Before opening the air conditioner, disconnect all power. If field replacement of a blower motor is necessary, most blower assemblies, including the mounting plate, are readily removable.
.IX. Trouble-Shooting Each Kooltronic Air Conditioner is engineered for performance and built for reliability. They are designed to require no routine maintenance other than the cleaning of ambient air filters. If your air conditioner should require warranty service, please contact Kooltronic. If you require service out of warranty, we have compiled a trouble-shooting chart to assist your service personnel. If additional assistance is required contact Kooltronic at (609) 466-3400.
