Fan blades are designed with appropriate pitch angle whichresult in maximum airflow through the condenser coil.

E. CONDENSER FAN MOTORCondenser fans, the impeller and motors are so constructed to form an integral unit. All fan motors shall be three phasewith class 'F' winding insulation and ball bearings for high ambient application. These fan motors are of totally enclosedair over type (TEAO) with inherent thermal protection of automatic reset type & specially designed for outdoor applica-tions.

F. SERVICE VALVESBoth suction and liquid service valves are brass, back seating type with sweat connections. Valves are externally locatedso refrigerant piping connections can be made quickly and easily.

G. CONTROL PANELThe control panel design is equivalent to NEMA-4 standard with hinged door for easy access ensuring dust and weath-erproof construction. Internal power and control wiring is neatly routed, properly anchored and all wires are identified withcable markers as per NEC standard applicable to HVAC units. The electrical controls used in the control panel arereliable to operate at high ambient conditions for a long period.

H. MICROPROCESSOR CONTROLLERThese condensing units are provided with a microprocessor based electronic control board and compatible to be oper-ated with external controllers such as a DDC or a Thermostat. The units control board has the following features:

• BALANCE LOADING OF COMPRESSORS: The unit’s electronic control automatically operates lead/lag sequenceof compressors. This is to load the compressors evenly over long periods of operation. If required however, compres-sor 1 can also be set to always lead. In this case, compressor 1 always starts first and stops last. (Selectable throughdip switch setting on control board).

• PUMP DOWN FUNCTION: In units equipped with pump down system, the controller provides the time delay betweensolenoid’s opening and compressor starting to equalize the pressure in the system necessary for compressor to start-up. (Selectable through dip switch setting on control board).

• COMPRESSOR ANTI-RECYCLING PROTECTION: The controller has a built-in 3 minutes minimum off timer forcompressor. This is for compressor protection in case of accidental manual re-set or immediate re-cycling of thermo-stat due to load demand.

• COMPRESSOR LOCK-OUT FUNCTION: If any of the unit’s safety control trips due to abnormal conditions, theelectronic controls locks out the compressor after a pre-determined timing preventing a re-start unless attended by aqualified service technician. The unit can be re-started through thermostat re-set after ensuring safe system condi-tions.

• FAULT DIAGNOSTICS: In case of system fault, LED’s on the board emits a flashing signal indicating where the faultis. This is to guide the service technician in identifying the fault.

• DIGITAL I/O’s: The unit’s control board is compatible to operate with a DDC controller or any standard 24V a.c.thermostat commercially available.

• SEQUENTIAL CONTROL: With input signals from the thermostat, the motors in the equipment is started in sequentialorder: supply fan – condenser fan – compressor; at a pre-determined timings.

K. COMPRESSOR OVER LOAD PROTECTORThe compressors has built-in thermal protector for its protection against high winding temperatures. Motor starter controlis equipped with an external overload relay as an additional protection against overload.

L. VOLTAGE MONITORING RELAYThis device protects the motors in the unit from faults such as; under or over voltage, unbalance & phase reversal of thepower supply. When the device sensed such faults, it will cut-off the supply in the control circuit thereby cutting off powerto the motors. The voltage monitor will re-set automatically when power is brought back to it’s normal conditions.

M. CRANKCASE HEATERSEach compressor has crankcase heater. The compressor crankcase heater is always on when the compressor is de-energized. This protects the system against refrigerant migration, oil dilution and potential compressor failure.

N. FILTER DRIERRefrigerant circuits are kept free of harmful moisture, sludge, acids and oil contaminating particles by the filter drier.Cartridge (sealed type) is standard for scroll compressor units and replaceable core filter drier for units with semi-hermetic compressors.

OPTIONS & ACCESSORIESA. CAPACITY CONTROLOn semi-hermetic compressors, capacity control is achieved by cycling compressors on /off and cylinder unloading. Theuse of unloading provides good part load capacities.

Hot gas bypass is available as an option on the lead circuit to permit operation of the system down to 80 % of its unloadedcapacity. Under low ambient condition, it controls temperature by eliminating the need to cycle the compressor on andoff, ensuring narrow temperature swing and lengthen the life span of the compressor.

B. ADVANCE MICROPROCESSORAdvance microprocessor control can be offered to achieve precise control and safety functions of the condensing units.Microprocessor is simple to use, push button keyboard allows to access the operating conditions, control set points andalarm history clearly displayed on a multi-line backed illuminated LCD panel. Also it’s compatible with building manage-ment system and adoptable to LON protocol.

C. FAN CYCLE SWITCH HEAD PRESSURE CONTROL (FCS)The capacity of air-cooled condensers varies with the difference between condensing temperature and condenser enter-ing air temperate (ambient temperature). It increases as this difference increases. For a given capacity, a drop in theambient temperature will lower the condensing temperatures and if the ambient temperature drops below a given limit,head pressure control is required.

Control shall be set for a minimum of 95°F (35°C) saturated refrigerant condensing temperature, or to suit the specifiedapplication.

D. PUMP DOWN SOLENOID VALVE (PDS)A pump down solenoid valve is installed in the liquid line. When the room thermostat is satisfied, the valve closes and thecompressor continues to run until a substantial portion of the refrigerant has been pumped out from the evaporator. Thelow-pressure switch will cycle off the compressor at a predetermined evaporator pressure.

E. COMPRESSOR CIRCUIT BREAKERProtect against compressor branch circuit fault. When tripped (Manually or automatically), the breaker opens the powersupply to the compressor and control circuit through auxiliary contacts.

F. PRESSURE GAUGESSuction & Discharge pressure gauges are available for both Scroll and Semi-Hermetic compressors. Oil pressure gaugescan be provided for Semi-Hermetic compressors only.

G. DISCHARGE LINE MUFFLERSDischarge line mufflers are installed to eliminate noise due to refrigerant pulsation.

H. SPRING ISOLATORS (for semi-hermetic compressors only)Compressors with spring isolators and vibration eliminators reduces the vibration transmitted from compressor to thepiping and unit structure.

I. CONDENSER COIL GUARDProtect the condenser coil from physical damage.

INSTALLATION & START-UP INSTRUCTIONSSAFETY CONSIDERATIONSImproper installation, service, maintenance or use can cause explosion, fire, electrical shock or other conditions which maycause 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 causepersonal injury or death.

SCROLL COMPRESSOR ROTATIONScroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correctrotation when the system is operated. Verification of correct rotation is by observing that the suction pressure drops anddischarge pressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially lowcurrent draw and by interchanging power supply wire L1 & L3 will correct this problem.

INSTALLATIONSTEP-1:Check equipment and job siteUnpack unit and move to final location taking care not to damage the unit. Remove screws holding the unit to woodenpallet and after removing wooden pallet, refix the screws.

STEP- 2:Installation on a solid, level mounting padWhen installing, allow sufficient space for airflow clearance, wiring, refrigerant piping and service. Allow 48" (1219 mm)clearance all around and no obstruction above unit for proper airflow. Double the service access when multiple units areinstalled at one location.On rooftop applications, locate unit at least 6" (152 mm) above roof surface. Place unit above a load-bearing wall, isolateunit 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 connectionsOutdoor units should be connected to indoor units using field-supplied piping of refrigerant grade and correct size. Theliquid 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 refrigerationstandard practice. Run refrigerant pipes as directly as possible, avoiding unnecessary turns and bends. Install refrigerantpipes 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. Makesure that no air & moisture enter the system as easter oil are hygroscopic in nature. The whole system should be leaktested and evacuated before charging the refrigerant.

Outdoor unit connected to factory matched indoor unitOutdoor unit contains holding charge only. The correct system refrigerant charge for operation is given in the unit nameplate & physicaldata table when connected with up to 25 ft (7.62 m) of field-supplied piping. Check refrigerant charge for maximum efficiency.

Sweat connectionUse refrigerant grade piping. Service valves are closed from factory when shipped and ready for brazing. After wrappingthe service valve with a wet cloth, the piping set can be brazed to service valve using either silver rod or silfos rod brazingmaterial. When brazing completed, refrigerant piping and indoor coil are now ready for leak testing. This check shouldalso 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. Useservice ports and open all valves.

ELECTRICALSTEP 1: INSTALLATIONA) 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 thanone disconnect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death.

B) Ground & power wiresConnect 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 unitUse 16 gauge color-coded wire between the indoor and outdoor units (control wiring).

STEP 2: START-UP1) 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.

SYSTEM DESIGNTHESE CONDENSING UNIT SYSTEM HAS BEEN DESIGNED BASED ON THE FOLLOWING:• Intended for outdoor installation with free air intake and discharge.• Minimum outdoor operating air temperature during cooling with low ambient operation option is 550F.• Maximum outdoor operating air temperature during cooling is 1300F.
