7-8. Auto Restart Function
7-8-1. How to set auto restart function
The indoor unit is equipped with an automatic
restarting function which allows the unit to restart
operating with the set operating conditions in the event
of power supply being accidentally shut down. The
operation will resume without warning three minutes
after power is restored.
This function is not set to work when shipped from the
factory. Therefore it is necessary to set it to work.
To set the auto restart function, proceed as follows:
The power supply to the unit must be on; the function
will not set if the power is off.
Push the [RESET] button located in the center
of the front panel continuously for three seconds.
The unit receives the signal and beeps three times.
The unit then restarts operating automatically in the
event of power supply being accidentally shut down.
When the unit is on standby (Not operating)

8. INSTALLATION PROCEDURE
8-1. Safety Cautions
For general public use
Power supply cord of parts of appliance for Outdoor use shall be at least polychloroprene sheathed flexible
cord (design H07 RN-F), or cord designation 245 IEC66.
CAUTION
New Refrigerant Air conditioner Installation
• THIS AIR CONDITIONER USES THE NEW HFC REFRGERANT (R410A), WHICH DOES NOT DESTROY
THE OZONE LAYER.
R410A refrigerant is apt to be affected by impurity such as water, oxidizing membranes, and oils because the
pressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. As well as the adoption of this new
refrigerant, refrigerating machine oil has also been changed. Therefore, during installation work, be sure that
water, dust, former refrigerant, or refrigerating machine oil does not enter into the refrigerating cycle of a
new-refrigerant air conditioner.
To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on
the main unit are different from those for the conventional refrigerant, and different size tools are also
required. Accordingly, special tools are required for the new refrigerant (R410A) as shown below. For
connecting pipes, use new and clean piping materials with high-pressure withstand capabilities, designed for
R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its
pressure withstand may be insufficient, and may contain impurities.
CAUTION
To Disconnect the Appliance from the Main Power Supply
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a
contact separation of at least 3 mm.
If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible after
installation. The plug must be disconnected from the power supply socket in order to disconnect the
appliance completely from the mains.
− 28 −
FILE NO. SVM-06027
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE
ALL POWER SWITCHES ARE OFF. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED
WRONGLY, ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT
WELL AWAY (MORE THAN 2 M) FROM HEAT SOURCES SUCH AS RADIATORS, HEATORS,
FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY
CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R410A) WITH ANY OTHER GASEOUS
BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE
REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY
HIGH AND IT RESULTINGLY CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE
INSTALLATION WORK, IMMEDIATELY LET FRESH AIR INTO THE ROOM. IF THE REFRIGERANT GAS
IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.

the noise level of the unit or where noise and discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.
REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER
Please make absolutely sure that the installation of this appliance is reported to the local power supplier
before installation. If you experience any problems, or if the installation is not accepted by the supplier, the
service agency will take adequate countermeasures.
Remark per EMC Directive 89/336/EEC
To prevent flicker impressions during the start of the compressor (technical process) following installation
conditions do apply.
1. The power connection for the air conditioner has to be done at the main power distribution. This distribution
has to be of an impedance.
Normally the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!
2. No other equipment should be connected to this power line.
3. For detailed installation acceptance, please contact your power supplier whether its restriction does apply
for products like washing machines, air conditioners or electrical ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.

8-3-3. Installation/Servicing tools
<Changes in the product and components>
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged
accidentally, the service port diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2
UNF 20 threads per inch)
• In order to increase the pressure withstand strength of the refrigerant piping, flare processing diameter and
size of opposite side of flare nuts have been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)
New tools for R410A
Applicable to R22 model
Changes
Gauge manifold
As pressure is high, it is impossible to measure by
means of conventional gauge. In order to prevent
any other refrigerant from being charged, each
port diameter has been changed.
Charge hose
In order to increase pressure withstand strength,
hose materials and port size have been changed
(to 1/2 UNF 20 threads per inch).
When purchasing a charge hose, be sure to
confirm the port size.
Electronic balance
for refrigerant charging
As pressure is high and gasification speed is fast,
it is difficult to read the indicated value by means
of a charging cylinder, as air bubbles occur.
Torque wrench
(nominal dia. 1/2, 5/8)
The size of opposing flare nuts has been increased.
Incidentally, a common wrench is used for nominal
diameters 1/4 and 3/8.
Flare tool
(clutch type)
By increasing the clamp bar's receiving hole,
strength of spring in the tool has been improved.
Gauge for projection
adjustment
Used when flare is made with a conventional flare
tool.
Vacuum pump adapter
Connected to conventional vacuum pump. It is
necessary to use an adapter to prevent vacuum
pump oil from flowing back to the charge hose.
The charge hose connecting part has two ports:
one for conventional refrigerant (7/16 UNF 20
threads per inch) and one for R410A. If the
vacuum pump mineral oil mixes with R410A,
a sludge may occur and damage the equipment.
Gas leakage detector
Exclusive for HFC refrigerant.
• Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and protector coating in
the U. S ARI specified rose color (ARI color code: PMS 507).
• Also, the "charge port and packing for refrigerant cylinder" require 1/2 UNF 20 threads per inch
corresponding to the port size of the charge hose.

8-5-3. Evacuating
<Packed valve handling precautions>
After the piping has been connected to the indoor unit,
you can perform the air purge together at once.
• Open the valve stem all the way out; but do not try
to open it beyond the stopper.
• Securely tighten the valve stem cap with torque in
the following table:
AIR PURGE
Evacuate the air in the connecting pipes and in the
indoor unit using
a vacuum pump. Do not use the refrigerant in the
outdoor unit.
For details, see the manual of the vacuum pump.
<Using a vacuum pump>
Be sure to use a vacuum pump with counter-flow
prevention function so that inside oil of the pump does
not flow backward into pipes of the air conditioner
when the pump stops. (If oil inside of the vacuum pump
enters into the air conditioner, which use R410A,
refrigeration cycle trouble may result.)
1. Connect the charge hose from the manifold valve to
the service port of the gas side packed valve.
2. Connect the charge hose to the port of the vacuum
pump.
3. Open fully the low pressure side handle of the
gauge manifold valve.
4. Operate the vacuum pump to start evacuating.
Perform evacuating for about 15 minutes if the piping
length is 20 meters. (15 minutes for 20 meters)
(assuming a pump capacity of 27 liters per minute.)
Then confirm that the compound pressure gauge
reading is −101 kPa (−76 cmHg).
5. Close the low pressure side valve handle of gauge
manifold.
6. Open fully the valve stem of the packed valves
(both sides of Gas and Liquid).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
