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.
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 water. 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.

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.

610mm (24") CLEARANCE MINIMUM
AIR OUT
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.

ELECTRICAL
STEP 1: INSTALLATION
A)
Please ensure regular power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements.
Caution:
Operation of the unit on improper power supply like generators 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 inside the control box.
C) Wiring
1. All wiring must comply with the "National Electric Code" and local electrical standards.
2. The power supply, voltage, frequency and phase must coincide with the unit nameplate.
3. Power wiring to the equipment must be adequately sized for maximum ampacity as shown on unit name plate; but not less than 14 gauge (2.5 mm 2 ) for lower amps.
4. For control wiring, use approved thermostat wire [minimum 18 gauge (0.75 mm 2 )], color coded wires. Never use telephone wire for this purpose.
5. Power supply should be checked to be certain that supply voltage agrees with equipment nameplate. Serious damage to compressors and motors can occur, if improper voltage is applied.
6. 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.
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.
SYSTEM DESIGN
THE 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 without low ambient operation option is 55
0 F (12.7
0 C).
•
For reliable operation, unit should be level on horizontal plane.
•
For interconnecting refrigerant pipe lengths greater than 25 feet (7.6 meters), check with your local Zamil sales office.
•
Use only copper wire for electric connection at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
