INDOOR UNIT FEATURES COMPACT DIMENSIONS Low height units are ideal to fit into tight spaces. Maximum height of unit ranges from 9.6" to 14.5" (24cm to 37cm). EASY INSTALLATION WITH FLARE NUT CONNECTIONS No need for complicated brazing for connecting the refrigerant piping. EASY MAINTENANCE / ONE SIDE ACCESS Filters can be easily removed by lifting/sliding. Piping and controls are on one side for easy access. DIGITAL & MICROPROCESSOR CONTROL WITH LCD DISPLAY THERMOSTAT Programmable wired thermostat loaded with all required functions and features for safe and smooth operation. QUIET, PULSE FREE AIR SUPPLY Centrifugal fans that are statically and dynamically balanced, handle upto 0.5" w.g. (125pa) external static pressure allowing you to keep the unit away from your comfort zone. MATCHED WITH RELIABLE CONDENSING UNITS For optimum performance in cooling and heat pump applications. Quiet Operation Digital Thermostat Compact Dimensions High Cooling Capacity Easy Installation STANDARD SPECIFICATIONS UNIT CONSTRUCTION These ducted indoor fan coil unit consists of a coil, motor/blower assembly, aluminum filter and a drain pan securely mounted on heavy gauge galvanized steel housing. Steel sheet panels are zinc coated and galvanized by the hot dip process of lock-forming quality conforming to ASTM A 653 commercial weight G-90. This unit is designed for those concealed overhead installations which require supply ductwork. A 1.5" duct collar is provided into the front panel for supply air duct connection. Return air is from the rear side. Access to the blower assembly is provided through the removable bottom panel from where the complete fan/motor deck can be removed for servicing. The panels are insulated with 5/16" thick polyethylene acoustic and thermal insulation. 1/2" (13mm) thick washable type aluminum filter is provided. BLOWER ASSEMBLY The direct drive blower motor assembly is easily accessible for complete servicing after removal of fan deck from the unit. The blower wheels are large in diameter and are of the forward curved design. Constructed of steel, they are statically and dynamically balanced for quiet and smooth performance. MOTORS Motors are permanent split capacitor type with three speed tapped windings. The bearings are of sleeve type. COILS All cooling coils are of corrugated fin & tube type, constructed of enhanced copper tubes and mechanically bonded to aluminum fins. As an option to aluminum fins, coated aluminum fins or corrugated copper fins may be provided. Tube support sheets are of galvanized steel, formed to provide structural strength. Coils are provided with the orifice type refrigerant metering device on all models (except DY18/DY24 heat pump models). This provides for ease of serviceability. Unlike capillaries there is no need for de-brazing/brazing required for site replacements of the orifice pistons. Accurately sized pistons can be easily fitted for non-standard applications (e.g. high rise buildings). Also this metering device eliminates the need for check valves in reverse cycle heat pump applications. All coils are factory tested at 350 psig. DRAIN PAN The condensate drain pan is fabricated of 18 gauge galvanized steel. The drain pan is powder coat painted and the outer surface is thermally insulated. Since water never touches the metal pan, then possibility of corrosion is eliminated. 3

Tube support sheets are of galvanized steel, formed to provide structural strength. Tubes are circuited to ensure minimum pressure drop and maximum heat transfer. Each coil is completely dehydrated, charged and sealed at the factory upon completion of pressure tests. 2. The fans are propeller type and direct-driven, front discharge & provided with fan guards. 3. Units are equipped with totally enclosed fan motors for greater reliability and dependable performance for many years. Inherent thermal protection is automatic reset type. 4. For heat pump version units, fixed orifice expansion device is inherent within the condensing units as standard (except DY18/DY24 heat pump models where capillary is provided in the indoor units). E. SERVICE VALVES Both suction and liquid service valves are brass, back seating type with flare connections. Valves are externally located so refrigerant tube connections can be made quickly and easily. Each valve has a gauge pressure port for ease of checking refrigerant operating pressures. F. LOW PRESSURE SWITCH Auto reset SPST switch activated by refrigerant pressure - locks out the compressor, if the refrigerant pressure falls below 25 PSIG. Also provides additional protection against evaporator freeze up due to loss of indoor airflow. 4

INSTALLATION - INDOOR UNIT The complete shipment should be inspected for damage. Any damage, visible or concealed, should be reported immediately to the delivery man or driver and noted on the shipping invoice. Place unit in position and make sure that unit is level. This is important to assure proper drainage and operation. Slots provided in the mounting brackets should be used for installing the units. Be sure that foreign material is not allowed to fall into or collect in the drain pan. Special care must be taken to prevent paint, plaster, insulation or other foreign material from being deposited on the motor or blower wheels. ELECTRICAL Please ensure power supply (V-Ph-Hz) to the unit is as per unit nameplate requirements. Caution: Operation of the unit on improper power supply will result in damage to the unit. Warning: Before installation or servicing, always TURN OFF all power to the unit. There may be more than one disconnect switch. Ensure all of them are turned off. Ground & Power wires Connect power wires as per wiring diagram. Connect ground wire to the ground lug inside the control box. Control wiring between outdoor & indoor units Use 16 gauge color-coded wire between the indoor and outdoor units (control wiring). Then match the auxiliary terminal block (ATB) numbers (indoor and outdoor units) to interconnect the two units. Note: 1. Field wiring to comply with local Safety and Fire codes. 2. Use copper wires of proper rating for all field wiring. 3. Install adequate branch disconnect switch as per NEC size requirements to handle unit starting current. Locate disconnect switch within sight and readily accessible from the unit. MAINTENANCE COIL: Coil may be cleaned by removing case and brushing between fins with a stiff wire brush. Brushing should be followed by cleaning with vacuum cleaner. The coil may also be cleaned by using a high pressure air, if compressed air source is available. It should be pointed out that if air filters are used and periodically cleaned, the coils will not be clogged up prematurely. DRAIN PIPE: Drain pipe should be checked before summer operation of unit is begun. If it is clogged, steps should be taken to clear the debris so that condensate will flow out easily. A standard pipe cleaner for 1/2" ID pipe may be used. Periodic checks of the drain pipe should be taken during summer operation, as there is a possibility of it becoming clogged with dirt. FILTER CLEANING: Remove access panel, slide filter out of filter rack, and clean as follows: Tap filter on solid surface to dislodge heavy particles. Wash under stream of hot water. If filter has been put to exceptional service, a mild solution of Sal-Soda, Tri-Sodium Phosphate or any other commercial solvent can be used. Set filter on end with slots in frame down, which allows it to drain. Filters should dry thoroughly before reuse. REPLACEMENT PARTS: When writing for replacement parts, refer to model number and serial number on the name plate of the unit. 14

INSTALLATION & START-UP INSTRUCTIONS - OUTDOOR UNIT SAFETY CONSIDERATIONS Improper installation, service, maintenance or use can cause explosion, fire, electrical shock or other conditions which may cause personal injury or property damage. Check with your nearest Zamil dealer/sales office for information or assistance. Warning: Before installation or servicing the system, always turn off main power supply. Electrical shock can cause personal injury or death. INSTALLATION STEP-1: Check equipment and job site Unpack unit and move to final location taking care not to damage the unit. Remove screws holding the unit to wooden pallet and remove wooden pallet. STEP- 2: Location of unit Place the unit with minimum clearance as shown in figure below to enable space for installation, service and optimum performance of the unit. Be sure that the discharge air from the condenser is not restricted. Double the clearance when multiple units are installed at one location. Units may be installed using mounting pads on the floor, concrete slabs, steel frames with adequate strength. AIR IN 203mm (8") FOR KY018, 024 & 030 254mm (10") FOR KY036 AND ABOVE 203mm (8") FOR KY018, 024 & 030 254mm (10") FOR KY036 AND ABOVE AIR IN AIR OUT 610mm (24") CLEARANCE MINIMUM 914mm (36") CLEARANCE MINIMUM STEP-3: Piping connections Outdoor units should be connected to indoor units using field-supplied piping of refrigerant grade and correct size. The liquid and suction line diameters can be determined from the physical data table. For piping requirements beyond 25 ft (7.62 m), obtain information from your nearest Zamil dealer/sales office. If either refrigerant piping or indoor coil is exposed to atmospheric conditions, it must be dehydrated to 500 microns to eliminate moisture contamination in the system. It is advisable to size piping according to recommended ASHRAE methods. Install piping according to refrigeration standard practice. Run refrigerant pipes as directly as possible, avoiding unnecessary turns and bends. Install refrigerant pipes carefully to prevent damaging the suction pipe insulation and vibration transmission to the structure. Outdoor unit connected to factory matched indoor unit Outdoor unit contains correct system refrigerant charge for operation with matched indoor unit as given on cooling capacity table and when connected with up to 25 ft (7.62 m) of field-supplied piping. Check refrigerant charge for maximum efficiency. 15
