1 Technical Guide SUNLINE 2000 SPLIT-SYSTEM EVAPORATOR BLOWER K4EU NOMINAL TONS (WORLD 50 HZ) DESCRIPTION These completely assembled units include a well-insulated cabinet, a DX cooling coil with copper tubes and aluminum fins, expansion valve(s), distributor(s), throwaway filters, a centrifugal blower, a blower motor, an adjustable belt drive, a blower motor contactor and a small holding charge of Refrigerant-22. The unit is manufactured under ISO 9002 Quality System Certification. The unit is shipped in the vertical position ready for field installation. It can be installed for horizontal operation by reversing the position of the solid bottom panel with the return air duct flange on the front of the unit. ACCESSORIES FIELD INSTALLED SUPPLY AIR PLENUMS A fully insulated plenum is available for free standing units located within the conditioned space, are shipped knocked-down for easy field assembly, are finished to match the exterior of the basic unit, and have double deflection grills that can be adjusted to vary the throw, spread and drop of the supply air. RETURN AIR GRILL An expanded metal grille is available for free standing units located within the conditioned space. It is finished to match the exterior of the basic unit and is shipped in one piece for easy installation. BASES A base is available to raise vertical units above the floor. Outdoor air may be introduced through the base by cutting an access opening to accommodate the outdoor air duct connection. The base is finished to match the exterior of the basic unit. It may have to be insulated in the field for certain applications. THREE-PHASE ELECTRIC HEATERS Electric heaters are available in five capacities to provide maximum flexibility. Both the air conditioning unit and the heater can be selected to precisely match the cooling and heating requirements of the conditioned space. These heaters are designed for easy field-installation over the supply air opening of the unit. Every heater is fully protected against excessive current and temperature by fuses and two high limit thermostats. Units with electric heat require only one power supply for both the heating elements and the supply air blower motor. The power wiring can be protected by either dual element/time delay fuses or an inverse time circuit breaker. FOR DISTRIBUTION USE ONLY - NOT TO BE USED AT POINT OF RETAIL SALE

HOT WATER COILS This drainable coil has two rows of 13mm (1/2 in.) copper tubes, eight aluminum fins per 25mm (1 in.), a casing that is finished to match the exterior of the basic unit, but no water control valve. The coil slides out of the casing for easy field installation. It should be mounted between the unit coil and blower section. STEAM COILS The non-freeze coil has one row of 25mm (1 in.) copper tubes, a 16mm (5/8 in.) copper tube inside each 25mm (1 in.) tube to distribute the steam evenly across the entire length of the coil, eight aluminum fins per 25mm (1 in.), a casing finished to match the exterior of the basic unit, but no steam control valve. The coil slides out of the casing for easy field installation and is pitched in the casing to facilitate condensate drainage. It should be mounted between the unit coil and blower sections. SUSPENSION KIT Suspension kit 1HH0451 is available for units installed horizontally. The accessory includes two channel iron supports and the hardware to secure them to the top of the unit. The hanger rods must be supplied by the field. THERMOSTATS Wall-mounted thermostats and subbases (24volt) with system and fan switches are available to control the operation of these split system air conditioners.
