MODEL DECODING
UNIT FEATURES GENERAL The CAX series air cooled condensing units from Zamil Air Conditioners are designed to provide engineering excellence in comfort air conditioning and industrial cooling with a superior combination of energy saving, performance, application flexibility, ease of service & maintenance and ability to withstand extreme ambient temperatures. These units can be combined with a wide variety of evaporator coils and blower packages to provide quite and dependable comfort. These units can be installed on a roof tops or at ground level. These CAX series units are designed to use ozone friendly HFC R-134a refrigerant. HFC R-134a is a singular compound form with proven highly efficient thermodynamic proprieties. The compound has no chlorine and does not contribute to Ozone depletion. There will be no phase out and no replacement costs for the life of the equipment.
SCROLL COMPRESSOR The Scroll compressor has one scroll, or spiral, orbiting in a path defined by a matching fixed scroll. The fixed scroll is attached to the compressor body. The orbiting scroll is coupled to the crankshaft and orbits, rather than rotates. The orbiting motion creates a series of gas pockets traveling between the two scrolls. On the outer portion of the scrolls, the pockets draw in gas, and then move into the center of the scroll, where the gas is discharged. As the gas moves into the increasingly smaller inner pockets, the temperature and pressure increase to the desired discharge pressure. Working Principle: The scroll compressors are consists of two involutes or Archimedean spirals (Figure-1). One spiral is positioned inside the other to form a series of crescent-shaped pockets. During compression the upper spiral remains stationary and the lower one, being eccentrically mounted on the drive shaft, describes an orbital rather than a simple rotary motion.
3
FIGURE- 1 How a Scroll Compressor works:
Compression in the scroll is created by the interaction of an orbiting spiral and a stationary spiral. A refrigerant enters the outer openings as one of the spirals orbits.
The open passages are sealed off as gas is drawn into the spiral.
As the spiral continues to orbit, the gas is compressed into two increasingly smaller pockets.
By the time the gas arrives at the center port, discharge pressure has been reached.
Actually, during operation, all six gas passages are in various stages of compression at all times, resulting in nearly continuous suction and discharge.
4
Refrigerant enters the compressor at the suction connection and flows around the motor’s housing and enters at the bottom side through the openings. Oil droplets separate from the refrigerant and fall into the oil sump. All suction refrigerant passes through the electrical motor, ensuring full motor cooling. After that the refrigerant enters the scroll elements.

INSTALLATION & START-UP INSTRUCTIONS 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.
SCROLL COMPRESSOR ROTATION Scroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correct rotation when the system is operated. Verification of correct rotation is by observing that the suction pressure drops and discharge pressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially low current draw and by interchanging power supply wire L1 & L3 will correct this problem.
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 after removing wooden pallet, refix the screws.
STEP- 2: Installation on a solid, level mounting pad When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping and service. Allow adequate clearance all around and no obstruction above unit for proper airflow. Double the service access when multiple units are installed at one location. On rooftop applications, locate unit at least 6" (152 mm) above roof surface. Place unit above a load-bearing wall, isolate unit and piping set from structure. Use 4"x4"x1" thick rubber/cork mounting pads. Arrange supporting members to adequately support unit and minimize transmission of vibration to building.
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 50 ft (15.24 m), obtain information from your nearest Zamil dealer/sales office. 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. Compressors are already charged with the required amount of lubricant. There is no need to charge in the field. Make sure that no air & moisture enter the system as easter oil are hygroscopic in nature. The whole system should be leak tested and evacuated before charging the refrigerant.
Outdoor unit connected to factory matched indoor unit Outdoor unit contains holding charge only. The correct system refrigerant charge for operation is given in the unit nameplate & physical data table when connected with up to 25 ft (7.62 m) of field-supplied piping. Check refrigerant charge for maximum efficiency.
Sweat connection Use refrigerant grade piping. Service valves are closed from factory when shipped and ready for brazing. After wrapping the service valve with a wet cloth, the piping set can be brazed to service valve using either silver rod or silfos rod brazing material. When brazing completed, refrigerant piping and indoor coil are now ready for leak testing. This check should also include all field and factory brazed joints. Warning: Relieve all pressure before refrigerant system repair or final unit disposal to avoid personal injury or death. Use service ports and open all valves. 48
ELECTRICAL STEP 1: INSTALLATION A) Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements. Caution: Operation of the unit on improper power supply will result in damage to the unit. Note: Use copper wires of proper rating for all field wiring. Warning: Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than one disconnect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death. B) Ground & power wires Connect power wires to terminal block per wiring diagram. Connect ground wire to the ground lug or plate provided inside the control box. C) Control wiring between outdoor & indoor unit Use 16 gauge color-coded wire between the indoor and outdoor units (control wiring).
STEP 2: START-UP 1) Energize crankcase heater for a minimum of 12 hours prior to the system start-up. To energize crankcase heater only, set thermostat to OFF position and close electrical disconnect switch to the outdoor unit. 2) Fully open liquid/suction service valves. 3) Close electrical disconnect switch to energize the system. 4) Set room thermostat to desired temperature.
