REFRIGERANT PIPING WORK

Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized

by the perfect piping work.

Piping Length And Elevation

If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to

flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective.

Always choose the shortest path and follow the recommendation as tabulated below.

Piping Connection

• Do not use contaminated or damaged copper tubing. If any piping, evaporator or condenser had been exposed or had been

opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic,

rubber plugs and brass nuts from the valves, fittings, tubing and coils until it is ready to connect suction or liquid line into

valves or fittings.

• If any brazing work is required, ensure that nitrogen gas is passed through coil and joints while the brazing work is being

done. This will eliminate soot formation on the inside wall of copper tubings.

• Cut the pipe stages by stages, advancing the blade of pipe cutter slowly. Extra force and a deep cut will cause more

distortion of pipe and therefore extra burr.

• Remove burrs from cut edges of pipes with a remover. Hold the end of the pipe downward to prevent metal chips from

entering the pipe. This will avoid unevenness on the flare face which will cause gas leak.

• Align the center of the piping and sufficiently tighten the flare nut with fingers. Finally, tighten the flare nut with torque

wrench until the wrench clicks.

• Be sure to execute heat insulation. (polyurethane form with thickness more than 15 mm)

• Except the outdoor unit which is pre-charge with refrigerant R22, the indoor unit and the refrigerant connection pipes must

be purged because the air that contain moisture remaining in the refrigerant cycle may cause malfunction to the compressor.

• Insert the flare nuts, mounted on the connection parts of both the indoor unit and outdoor unit onto the copper pipes.

• Flare the pipe with extra length above the flaring tool as shown in the table.

• The flared edge must be even and not cracked or scratched.

• All wires must be firmly connected.

• Make sure all the wire not touching the refrigerant piping, compressor or any moving parts of the fan motor.

• The connecting wire between the indoor unit and the outdoor unit must be clamped on the wire clamps.

• The power supply cord must be equivalent to H07RN-F (245 IEC65, 245 IEC66) which is the minimum requirement.

• When attaching the terminal box lid, make sure do not pinch any wires.

• After all the wiring connections are done, fill in any gaps/holes with insulation (procured locally) to prevent small animals

and insects entering the unit from outside.

• Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to

the indication on terminal block. (Refer to the wiring diagram attached on the unit).

Electric wire

Step to connect the installation wire:

• Used the correct screwdriver for tightening the terminal screws. If the block is too small, the mad of the screw might be

damaged and the screw will not be properly tightened. If tightening too hard, screw might be damaged.

• Do not connect wire at different gauge to the same proper supply terminal.

• Use specified electric wire. Connect the wire securely to the terminal. Lock the wire down without applying excessive

force to the terminal.

• Keep wiring in mat order and not to obstruct other equipment such as popping open the terminal box lid.

VACUUMING AND CHARGING

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare

valve fittings.

Vacuuming for indoor unit

Before vacuuming, perform leak check for refrigeration circuit. After the system piping are properly connected, connect the

flexible hoses to the correct charging nipples as shown in the diagram. Ensure that flexible hose from charging nipples are

connected to the vacuum pump via standard servicing valves and pressure gauges (gauge manifold). Vacuum the air conditioner

system to at least 500 microns Hg. Do not start the unit when the system is engaged in vacuuming. The outdoor is pre-charge.

SPECIAL PRECAUTIONS WHEN CHARGING UNIT

1. Charging procedures – Single phase compressors

Evacuate the system to 500 microns Hg. (67Pa). To reduce evacuation time, use short, large diameter hoses and connect to

unrestricted service ports on the system. Quality of vacuum cannot be determined by time – a reliable vacuum gauge must

be used. (etc. electronic vacuum gauge)

Turn the refrigerant cylinder upside down, purge the charging hose and charge liquid through the liquid line charging port

until refrigerant no longer flows or until the correct charge has been weighed in. If additional charge is required start the

system and slowly bleed liquid into the suction side until the system is full.

Copeland recommends charging liquid in a CONTROLLED manner into the suction side until the system is full.

This recommendation does not hold true for reciprocating compressors where liquid charging into the suction side could

cause severe damage.

Carefully monitor the suction and discharge pressures – ensure that the suction pressure does not fall below 25 psig (1.7

bar) at any time during the charging process.

• Manifold Gauge will show cylinder pressure rather than suction pressure if the cylinder valve and Manifold

valve “A” are both open.

! CAUTION

A

There are many ways of charging liquid in a “controlled manner” into the suction

side:-

1. Use valve A on the manifold gauge set

2. Use the valve on the refrigerant cylinder

3. Charge through a Shredder valve

4. Use a hose with a Shredder valve depressor

5. Charge into the suction side at some distance from the compressor

6. All of the above

2. Charging procedures – Three phase compressors

The fundamental procedure is the same as for single phase models but the compressor can run in the wrong direction on

starting. If this happens reverse any two phases and start again. Short term reverse rotation will not damage the compressor.

All Specter compressors (Model: ZR90 to ZR19M) have internal discharge temperature protectors which are very effective

in preventing dangerously high discharge temperatures during charging. The protection module will trip and lock the

compressor out for 30 minutes. It is not normally necessary to wait 30 minutes for the module to reset. When the compressor

has cooled down the module can be reset by breaking the power supply to the control circuit. Very often the serviceman

does not understand why the module tripped and uses a jumper wire to bypass it. He continues to charge the system and

removes the jumper when charging is complete. The compressor may or may not run with the protector back in the circuit

but it is certain that the compressor has been damaged and premature failure is inevitable.

Short Duct Specification

• The indoor unit is provided with air discharge and air intake “knock-out” hole for duct connection. However the connection

of the short duct for air discharge is possible on only one side.

• The use of short duct for air discharge will improve airflow distribution if there is an obstruction (such as a lighting fixture)

or in a long, narrow room or an L-shaped room. It also use for air conditioning of two rooms simultaneously.

NOTE

• Avoid using the short duct on which the air discharge grille can be completely closed, to prevent evaporator freezing.

• In order to prevent condensation forming, be sure that there is sufficient thermal insulation and no leakage of cool

air when installing the short duct.

• Keep the introduction of fresh air intake within 20% of total air flow. Also provide a chamber and use a booster fan.

Sealing Material

• It is possible to seal one of the four air discharge outlet. (sealing two or more air discharge outlet could cause a malfunction)

• Remove the front panel and insert the sealing material into the air discharge outlet on the indoor unit to seal the air outlet.

• The sealing material is the same length as the longer air discharge outlet. If it is desired to seal the shorter air discharge

outlet, cut the sealing material to shorten it.

• Push the sealing material in about 10 mm beyond the bottom surface of the indoor unit so that it does not touch the air

louver. Be sure not to push the sealing material in any farther than about 10mm.

INDICATOR LIGHTS

Remote Control

When there is infrared remote control operating signal, the signal receiver on indoor unit will made a <beep> for signal

acceptance confirmation.

NOTE

CDF LED = Cool/Dry/Fan LED, turns on in these modes

The unit will not detect sensor missing when the compressor is ON

OVERALL CHECKING

• After installation of the unit, ensure that :-

1. The unit has been mounted solidly and rigid in position.

2. Outdoor unit is fully installed

3. Gas leak test is been checked.

4. Unit is fully insulated.

5. The drainage is flow smoothly - pour some water into the main drain pipe from the flexible drain hose.

6. The power supply, voltage correspond to that unit shown on wiring diagram are attached on the unit.

7. Wiring and piping install correctly and firmly.

8. Unit is safely grounded.

9. Wiring size is according to specification.

10. Air inlet and outlet are not blocked.

11. Note down the refrigerant piping length and additional refrigerant charge.

• Test run

1. Conduct a test run after water drainage test and gas leakage test.

2. Check the following items :-

a. Is the electric plug firmly inserted into the socket ?

b. Is there any abnormal sound from the unit ?

c. Is there any abnormal vibration on the unit itself or piping ?

d. Is the drainage of water smooth ?

• Confirm that :

1. Condenser fan is running, with warm air blowing off the condensing unit.

2. Evaporator blower is running and discharge cool air.

3. The remote control incorporate a 3 minute delay in the circuit. Thus, it requires about 3 minutes before the outdoor

condensing unit can start up.
