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 LengthAnd 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 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.
• No additional charge of compressor oil is permitted.
•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 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.Alack 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.
