INSTALLATION OF THE OUTDOOR UNIT

The outdoor unit must be installed such that there is no short

circuit of the discharge air or obstruction to smooth air flow.

Respect the installation clearance. Select the coolest possible

place where intake air should not be higher than the outside

temperature (maximum 45°C).

Ensure that there are no obstruction of air flow into or out

of the unit. Remove obstacles which block air intake or

discharge.

REFRIGERANT PIPING

Maximum Pipe Length And Maximum Number Of

Bends

When the pipe length becomes too long, both the capacity

and reliability drop. As the number of bends increases,

system piping resistance to the refrigerant flow increases,

thus lowering the cooling capacity. As a result, compressor

reliability will be affected. Always choose the shortest path

and follow the recommendation as tabulated below:

Piping Works And Flaring Technique

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, vacuum the system.

Generally, do not remove plastic, rubber plugs and brass

nuts from the valves, fittings, tubings and coils until it is

ready for connection.

If any brazing work is required, ensure that the nitrogen gas

is passed through piping and joints while the brazing work

is being done. This will eliminate soot formation on the

inside walls of the copper tubings.

Cut the pipe stage by stage, advancing the blade of pipe

cutter slowly. Extra force and deep cut will cause more

distortion of pipe and therefore extra burr.

Remove burrs from cut edges of pipes with a remover as

shown in Fig. R. This will avoid unevenness on the flare

faces which will cause gas leak. Hold the pipe on top position

and burr remover at lower position to prevent metal chips

from entering the pipe.

Insert the flare nuts mounted on the connection parts of both

indoor and outdoor unit, into the copper pipes.

The exact length of pipe protruding from the face of the

flare die is determined by the flaring tool.

Fix the pipe firmly on the flare die. Match the centers of

both the flare die and the flaring punch, and tighten flaring

punch fully.

Piping Connection To The Units

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.

When tightening the flare nut with the torque wrench,

ensure that the direction for tightening follows the arrow on

the wrench.

The refrigerant pipe connection are insulated by

polyurethane (ARMAFLEX type or similar).

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

R410A is a new HFC refrigerant which does not damage the

ozone layer. The working pressure of this new refrigerant is

1.6 times higher than conventional refrigerant (R22), thus

proper installation / servicing is essential.

• Never use refrigerant other than R410A in an air condi-

tioner which designed to operate with R410A.

• POE oil is used as lubricant for R410A compressor, which

is different from the mineral oil used for R22 compressor.

During installation or servicing, extra precaution must be

taken not to expose the R410A system too long to moist

air. Residual POE oil in the piping and components can

absorb moisture from the air.

• To prevent mischarging, the diameter of the service port

on the flare valve is different from that of R22.

SPECIAL PRECAUTIONS WHEN DEALING WITH R407C UNIT

• R407C is a zeotropic refrigerant mixture which has zero

ozone depletion potential and thus conformed to the

Montreal Protocol regulation. It requires Polyol ester oil

(POE) oil for its compressor's lubricant. Its refrigerant

capacity and performance are about the same as the

refrigerant R22.

• POE oil is used as lubricant for R407C compressor, which

is different from the mineral oil used for R22 compressor.

During installation or servicing, extra precaution must be

taken not to expose the R407C system too long to moist

air. Residual POE oil in the piping and components can

absorb moisture from the air.

• Refrigerant R407C is more easily affected by dust of

moisture compared with R22, make sure to temporarily

cover the ends of the tubing prior to installation.

• No additional charge of compressor oil is permitted.

• Use tools and materials exclusively for refrigerant R410A.

Tools exclusively for R410A are manifold valve, charging

hose, pressure gauge, gas leak detector, flare tools, torque

wrench, vacuum pump and refrigerant cylinder.

• As an R410A air conditioner incurs higher pressure than

R22 units, it is essential to choose the copper pipes cor-

rectly. Never use copper pipes thinner than 0.8mm even

though they are available in the market.

• If the refrigerant gas leakage occurs during installation /

servicing, be sure to ventilate fully. If the refrigerant gas

comes into contact with fire, a poisonous gas may occur.

• When installing or removing an air conditioner, do not

allow air or moisture to remain in the refrigerant cycle.

• No other refrigerant other than R407C.

• Tools specifically for R407C only (must not be used for

R22 or other refrigerant)

i) Manifold gauge and charging hose

ii) Gas leak detector

iii) Refrigerant cylinder/charging cylinder

iv) Vacuum pump c/w adapter

v) Flare tools

vi) Refrigerant recovery machine

• Filter-dryer must be installed along the liquid line for all

R407C air conditioners. This is to minimise the

contamination of moisture and dirt in the refrigerant

system. Filter-dryer must be of molecular sieve type. For

a heat-pump system, install a two-way flow filter dryer

along the liquid line.

PURGING THE REFRIGERANT PIPING

Purging The Piping And The Indoor Unit

Except the outdoor unit which is pre-charged with

refrigerant, the indoor unit and the refrigerant connection

pipes must be air purged because the air that contain moisture

remaining in the refrigerant cycle may cause malfunction to

the compressor.

The outdoor unit is equipped by two 3 ways refrigerating

connecting valves. The suction valve is the larger one while

the small one is the liquid valve. Both valves are supplied

with service port valve for connection to a manometer.

• Remove the caps from the valve and the service port.

• Connect the center manifold gauge with the vacuum pump.

• Connect the manifold gauge to the service port of the 3

ways valve.

• Start the vacuum pump. Check the low pressure manifold

gauge until it indicate 0.9 bar. The evacuation time varies

with each vacuum pump capacity but generally in half an

hour.

• Close the manifold valve and stop the vacuum pump.

• On the outdoor unit, open the suction and liquid valve

(anti clockwise) with 4 mm key for hexagon sacked screw.

• The air conditioner unit is ready for start.

• If the reading is close to 0, the refrigerant circuit must be

evacuated (by vacuum pump) and charged again.

ADDITIONAL CHARGE

The refrigerant is pre-charged in the outdoor unit. If the

piping length is less than 5 m, additional charge after vacu-

uming is not necessary. When the piping length is more than

5 m, use the table below.

Additional Charge Operation

This operation must be done by using gas cylinder and a

precise weighing machine obligatorily. The additional charge

is top up into the outdoor unit by suction valve via service

port.

• Remove the service valve plug.

• Connect the low pressure manifold to the suction service

port, center manifold to the cylinder tank and close the

high pressure manifold (see figure below).

Purge all the flexible hose with refrigerant gas.

• Start the air conditioner unit.

• Open the gas cylinder and low pressure manifold valve.

• When the required refrigerant quantity is pumped in the

unit, close the low pressure manifold and the gas cylinder

valve.

• Disconnect the manometer and the gas cylinder. Place back

the service port cap.

Check Refrigerant Leak

Check with refrigerant detector whether there is a leak on the flare type connection of the indoor unit and outdoor unit.

Hints: After operation for sometime, check if there is oil traces, there is a leak.

SPECIAL PRECAUTIONS WHEN CHARGING UNIT WITH

COPELAND SCROLL COMPRESSORS

These precautions are intended for use with Copeland Scroll compressors only with R22, R407C, R134A, R404A, R507 and

R410A refrigerants but are not applied to Copeland reciprocating compressors or competitive Scroll compressors.

Scroll compressors have a very high volumetric efficiency and quickly pump a deep vacuum if there is insufficient refrigerant

in the system or if refrigerant is added too slowly. Operation with low suction pressure will quickly lead to very high discharge

temperatures. While this process is happening, the scrolls are not being well lubricated – scrolls depend on the oil mist in the

refrigerant for lubrication. A lack of lubrication leads to high friction between the scroll flanks and tips and generates additional

heat. The combination of heat of compression and heat from increased friction is concentrated in a small localized discharge

area where temperatures can quickly rise to more than 300˚C. These extreme temperatures damage the Scroll spirals and the

orbiting Scroll bearing. This damage can occur in less than one minute especially on larger compressors. Failure may occur in

the first few hours or the damage done during field charging may show up some time later.

Other typical field charging problems include undercharging, overcharging, moisture or air in the system etc. In time each one

of these problems can cause compressor failure.

Minimal equipment is required for field charging. The minimum equipment required to do a satisfactory job is:-

Set of service gauges Vacuum gauge

Hoses Scales

Vacuum pump Thermometer

The proper refrigerant charge should follow the volume as recommended by manufacturer and recommendation should be

followed by the installer.

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.

1-12

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

valve “A” are both open.

! Caution

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.

A

OVERALL CHECKING

Ensure the following, in particular:-

1) The unit is mounted solidly and rigid in position.

2) Piping and connections are leak proof after charging.

3) Proper wiring has been done.

Drainage check:- Pour some water into left side of drain

pan (drainage are in right side of unit).

• Test run:

1) Conduct a test run after water drainage test and gas

leakage test.

STANDARD OPERATING CONDITION

Cooling Only Unit

Heat Pump Unit

2) Watch out for the following:-

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

b) Is there any abnormal sound from unit?

c) Is there smooth drainage of water?

• Check 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 controller incorporates a 3 minute delay in

the circuit. Thus, it requires about 3 minutes before the

outdoor condensing unit can start up.

! Warning

• Disconnect from the main power supply before servicing the air conditioner unit.

• DO NOT pull out the power cord when the power is ON. This may cause serious electrical shocks which may

result in fire hazards.
