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. 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 compres-
sor.
Additional Charge
The refrigerant is pre-charged in the outdoor unit, but additional charge of refrigerant after vacuuming is necessary. Follow
the recommendation as tabulated below.

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 R410Acompressor, 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.
•Use tools and materials exclusively for refrigerant R410A.
Tools exclusively for R410Aare 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 additional charge of compressor oil is permitted.
• 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.

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
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.
Charging
Before charging, the vacuum must be held at 500 microns Hg
for at least 15 minutes, then break vacuum by charging R-22
refrigerant. Operate the unit for 15 minutes and ensure the
refrigerant charges is of correct by monitoring running current,
gas and liquid line pressures. Suction and discharge pipe
pressure should be in the region of 75 psig and 275 psig
generally.
After ensuring the system is correctly charged, remove flexible
hose from charging nipples and replace caps.
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.
• Manifold Gauge will show cylinder pressure rather than suction pressure if the cylinder valve and Manifold
valve “A” are both open.

Remote Control
When there is infrared remote control operating signal, the signal receiver on indoor unit will made a <beep> for signal
acceptance confirmation.
OVERALL CHECKING
• Ensure that:
1) The unit has been mounted solidly and rigid in position.
2) Piping and connections are leak proof after charging.
3) Proper wiring has been installed.
• Drainage check:
– Pour some water into the main drain pipe from the flexible drain hose.
• 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.

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.
