Caution 35 1 The Daikin Water Cooled Packaged Air Conditioners are available in 14 models from UCPJ100N(9.4/10.4kW, 50/60Hz) to UCJ2000N(193.5/213.9kW, 50/60Hz). The light and compact construction ensures easy installation in any building whether new or existing. They are ideally suited to cooling offices, banks theaters, restaurants, etc. In case an optional heater (listed on page 5) is fitted, comfortable heating is also possible. You can choose the model best suited to your requirements from the wide range available in this series. UC(P)J100N~670P : Designed for operation with ducting, but an optional plenum chamber (except UCPJ100N) is mounted on a unit, it can be installed directly in a room without ducting. UCJ850N~2000N : Designed for operation with ducting only. Easy installation: These self-contained units are assembled internally wired and charged with refrigerant in the factory and are subjected to a stringent test run before delivery. All that is required on the spot are water piping, wiring to the main power supply and ducting. The weight of the models smaller than UCJ2000N has been greatly reduced for easy handling. Economical operation: An electronic thermostat precisely controls compressor operation according to room temperature to save power. UCJ500P~2000N: Cooling is controlled in 2 or 4 steps by an unloader mechanism or on/off operation of a compressor in the 2 or 3 refrigerant circuits according to cooling load. Easy operation and maintenance: Operation is very easy and controlled centrally from the control panel fitted on the front of the units. A red pilot lamp indicates normal operation, and white lamp indicates abnormal operation. ln addition, various pressure gauges are connected to each refrigerant circuit for easy monitoring. ¡The switches, gauges, pilot lamps on the control panel are as follows: UCPJ100N~335P: Master control knob, selector switch for COOL/HEAT, thermostat knob, red pilot lamp, high pressure reset button. UCJ500P~2000N: Master control switch, selector switches for COOL/HEAT and LOCAL/REMOTE, thermostat knob, red pilot lamp, white pilot lamp, high pressure reset button, discharge pressure gauge (Except UCJ500P·670P), suction pressure gauge (Except UCJ500P·670P). ¡A selector switch and terminal for remote control are fitted to UCJ500P~2000N for remote operation. ¡A washable air filter is fitted on all models. It can be easily detached for cleaning. Quiet: Quiet multi-blade fans and hermetically sealed compressors mounted with vibration isolation rubber pads (Models smaller than UCJ2000N) ensure quiet operation. In addition, the air passage inside the unit is designed to minimize air resistance for quiet operation. Main components: ¡Daikin developed highly efficient and compact compressors that are equipped with various safety devices for additional reliability and durability. UCPJ100N: A hermetically sealed rotary compressor lubrication system with the eccentric hole is incorporated. UC(P)J170~670P, 1000P, 1320P: Adoption of scroll compressor UCJ850N, 1600N, 2000N: The hermetically sealed reciprocating type compressor is adopted. The lubrication method is of the eccentric hole system. ¡The eveporator is of the unique patented cross fin coil type. Waffle louver fins *1 or Waffle fins and Hi-X tubes *2 (with internal surface modified by serration) are used to greatly improve the heat exchange coefficient. ¡The condenser is also an usually efficient heat exchanger. UC(P)J100N~1320P: The double tube type condenser with corrugated and wire or needle shaped fin inner tubes are used to increase heat transfer efficiency. UCJ1600N~2000N: The shell and cross fin tube type condenser is used. The refrigerant can be pumped down by using the stop valves at the condenser outlet and the compressor discharge side. ¡The evaporator fan is of the dual suction multi-blade type and is V belt driven. Operative air flow range is widened for UC(P)J100N~2000N. In paticular, a variable pitch pulley is attached to UC(P)J100N~670P for ease of ducting. ¡The evaporator fan motor is equipped with a thermal protector or an overcurrent relay for safe operation.
