1 LOCATION OF OUTDOOR UNIT
Select the location considering the following:
O U T D O O R U N I T
1 .The location must allow easy servicing and provide good air circulation as shown in fig2.
2.The unit may be suspended from a wall by a bracked(Optional)or located in a free standing
position on the floor(preferably slightly elevated).
3.If the unit is suspended , ensure that the bracket is firmly connected and the wall is strong
enough to withstand vibrations.
4.Unit location should not disturb neighbours with noise or exhaust air stream.
5.Place the mounting pads under the unit legs.
6.Refer to figure 2 for allowed installation distances.

2 ELECTRICAL CONNECTION BETWEEN
OUTDOOR AND INDOOR UNIT
ELECTRICAL REQUIREMENTS
Electrical wiring and connections should be made by qualified electricians and in accordance
with local electrical codes and regulation.The air conditioner units must be grounded. The air
conditioner units must be connected to an adequate power outlet from a separate branch
circuit protected by a time delay circuit breaker,as specified on unit's nameplate. Voltage
should not vary beyond ± 10% of the rated voltage.
1 .Remove the power supply cable that is connected to the indoor unit!
2.To connect the indoor units to the outdoor units,use the following electrical cables.
Electrical connections:
Power input cable: 1 group 3 wiresX2.5mm
2
cable between indoor and
outdoor units:
1 group 4 wiresX 1.0mm
2
see Fig 6.7.8.9.10 for detail .
3.Prepare the cable ends for the power input and for the cables between outdoor and indoor
units as shown in figure 3a and 3b respectively.
4.Connect the cable ends to the terminals of the indoor and outdoor units , as show in fig4, figs.
Please select corresponding connection according to the different indoor units. 5.Secure the

New Refrigerant Air Conditioner Installation
This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer.
R410A refrigerant is approx . 1.6 times of refigerant R22. Accompanied with the adoption of the
new refrigerant , the refrigeration machine oil has also been changed.
Therefore,during installation work, be sure that water , dust , former refrigerant , or refrigeration
machine oil does not enter into the new type refrigerant R410A air conditioner circuit.The system
must not be left open to the atmosphere for any reason for any period of time as the systems oil
quickly absorbs moisture and will contaminate and damage the system.
A refrigerant liquid line drier is recommended.
To prevent mixing of refrigerant or refrigerating machine oil ,the sizes of conneting sections of
charging port on main unit and installation tools are different from those used for the conventional
refrigerant units. Accordingly,special tools are required for the new refrigerant (R410A) units,
For connecting pipes use new and clean piping materials with high pressure f i t t i n g made for
R410A only, so that water and/or dust does not enter.Moreover, do not use the existing piping
because there are some problems w i t h presure f i t t i n g s and possible i m p u r i t i e s in e x i s t i n g
piping .
Changes in the product and components
In air conditioners using R410A ,in order to prevent any other refrigerant from being accedentally
charged .the service port diameter size of the outdoor unit control valve (3 way valve) has been
changed. (1/2 UFN 20 threads per inch)
• In order to increase the pressure resisting strength of the refrigerant piping ,flare processing
diameter and opposing flare nuts sizes have been changed.( fot copper pipes with nomensions
1/2 and 5/8)
New tools for R410A
Nes tools for R410A
Applicable to R22 model
Chages
Gauge manifold
x
As the working pressure is high ,it is impossible
to measure the working pressure using
conventional gauges . In order to prevent
any other refrigerant from being charged ,
the port diameters have been changed.
Charge hose
x
In order to increase pessure resisting strength.
hose materials and port sizes have been changed(
to 1 /2 UNF 20 threads per inch).
When puchasing a charge hose,be sure to confirm
the port size.
Electronic balance for
refrigerant charging
As working pressure is. high and gasification
speed is fat ,it is difficult to read the indicated
value by means of charging cylinder ,as air
bubbles occur.
Torque wrench
(nominal dia.1/2,5/8)
x
The size of opposing flare nuts have been
increased ,incidentally,a common wrench is
used for nominal diameters 1/4 and 3/8.

By incressing the clamp bar'receiving hole
size , strength of spring in the tool has been
improved.

Used when flare is made by using conventional
flare tool.
Vacuum pump adapter 0
Connected to conventional vacuum pump,it is
necessary to use an adapter to prevent vacuum
pump oil from flowing back into the charge
hose ,
The charge hose connecting part has two
ports-one for conventional refrigerant (7/16
UNF 20 theads per inch )and one for R41 OA ,if

protector coating in the U.S's ARI specified rose color (Ari color code; PMS 507).
•Also the "charge port and packing for refrigerant cylinder"requires 1/2 UNF 20 theads per inch
corresponding to the charge pOse's port size.
4 REFRIGERANT TUBING
CONNECT THE INDOOR TO THE OUTDOOR UNIT
The indoor unit contains a small quantity of nitrogen.Do not unscrew the nuts from the unit until
you are ready to
connect the tubing.The outdoor unit is supplied
with suffcient refrigerant charge(R410A). Refer
to outdoor unit nameplate.
To prevent crushing,bend tubes using a bending
tool.
NOTE:Use refrigeration R410Atype copper
tubing only.
1.Open the valve cover.
2.Use tubing diameter that corresponds to the
tubing diameter of the indoor and outdoor units.
Note that the liquid and suction tubes have
different diameters.(See tube size,torque
tightening table.)
3.Place flares nuts on tube ends before preparing
them with a flaring tool.Use the flare nuts that
are mounted on the supplied outdoor and indoor
units.
4.Connect the all ends of the tubing to the
indoor and outdoor units.Notice the sign . All
ends should correspond one by one.
5.Insulate each tube separately,and their
unions,with at least 6mm thick of
insulation .Wrap the refrigerant tubing,drain
hose and electric cables together with a vinyl tape (UV protected).
73 SERVICE MANUAL FOR CMV
Caution!
When unscrewing the
valve caps, do not stand
in front of them or the
spindles at any time,as
the system is under
pressure.

EVACUATION OF THE REFRIGERATION TUBES AND THE INDOOR UNIT
After connecting the unions of the indoor and outdoor units,evacuate the air from the
tubes and indoor unit as follows:
Tightening torques
of unions and
valve caops:
74 SERVICE MANUAL FOR CMV
1.Connect the charging hoses with a push pin to the low and high sides of the charging
set and the service ports of the suction and liquid valves.
Be sure to connect the end of the charging hose with the push pin to the service
ports. 2.Connect the center hose of the charging set to a vacuum pump.
3.Open Fully the low and high pressure sides of the manifold gauge valves.
4.Turn on the vacuum pump.Perform evacuating for at least 30 minutes and than confirm
that the needle in the gauge moves from 0 MPa(Ocm Hg) t 0 - 0 . 1 MPa(-76cm Hg).
5.Close the valves of the low and high sides of the charging set and turn off the vacuum
pump. After few m i n u t e s , i f the gauge needle has moved,there is a leak which must be
found and repaired before moving to the next stage.
6.Disconnect the charging hose from the vacuum pump and from the service ports of the
suction and liquid valves.
7.Tighten the service port caps of suction and liquid valves.
8.Remove the valve caps from all valves,and open them using a hexagonal Allen
wrench, 9.Securely tighten the caps onto all of the valves.
10.Check for gas leaks from all the connecting p os i t io n . Tes t w i t h electronic leak
detector or with a sponge immersed in soapy water for bubbles.
