Piping Materials
(1)
Prepare locally-supplied copper pipes.
(2)
Select clean copper pipes. Make sure there is no dust and moisture inside of the pipes. Blow the inside of the pipes with
nitrogen or dry air, to remove any dust or foreign materials before connecting pipes.
(3)
Piping thickness and material use the pipe as below.

Processing of Refrigerant Piping
(1)Pipe cutting
·Cut the cooper pipe correctly with pipe cutter.
(2)Burrs removal
·Completely remove all burrs from the cut cross section of the pipe.
·Put the end of the copper pipe downward to prevent burrs from dropping in the pipe.
(3)Putting nut on
·Remove flare nuts attached to indoor and outdoor units, then put them
on pipe having completed burr removal.
(Not possible to put them on after flaring work).
·Flare nut for R410A pipe may differ from R22 pipe depending on the diameter of pipe.
(4)Flaring work
·Perform flaring work using flaring tool as shown below.
(5)Check
·Compare the flared work with the figure below.
·If flare is noted to be defective, cut off the flared section and perform flaring work again.

Piping Connection
( )
1 Confirm that the valve is closed.
( )
2 Connect the indoor unit and the outdoor unit with field-supplied
refrigerant piping.Suspend the refrigerant piping at certain points and
prevent the refrigerant piping from touching the weak part of the
building such as wall, ceiling, etc.
(If touched, abnormal sound may occur due to the vibration of the piping.
Pay special attention in case of short piping length.)
(3)Tightening the flare nut use two spanners like figure right.
(4)Apply the refrigerant oil (filed-supply)thinly at the seat surface of the
flare nut and pipe before connecting and tightening.
And when tightening the flare nut, use two spanners.
(5)Outdoor refrigerant piping should connect with stop valve.
(6)After finishing connecting the refrigerant pipes, keep it warm with
the insulation material like figure right.
·For outdoor unit side, surely insulate every piping including valves.
·Cover piping joints with pipe cover.
·Using piping tape, apply taping starting from the entry of
outdoor unit.Fix the end of piping tape with adhesive tape.

Air Tight Test
Air Tight Check
Do use Nitrogen.
Connect the gauge manifold using charging hoses with a nitrogen
cylinder to the check joints of the liquid line and the gas line stop valves.
Perform the air-tight test.
Don't open the gas line stop valves.
Apply nitrogen gas pressure of 4.15MPa.
Check for any gas leakage at the flare nut connections, or brazed parts by gas leak
detector or foaming agent. Gas pressure doesn't decrease is OK.
After the air tight test, release nitrogen gas.

Vacuum Pumping nd harge efrigerant
Vacuum Pumping
(1)Connect a manifold gauge to the check joints at the both sides. Continue vacuum pumping work until the pressure reaches 756mmHg or lower .
(2)After vacuum pumping work, stop the manifold valve's valve, stop the vacuum pump and leave it for one hour. Check to ensure that the
pressure in the manifold gauge does not increase.
(3)Fully open the gas valve and liquid valve slowly.
(4)Open adjusted valve to add refrigerant (must be refrigerant is liquid).
(5)After the refrigerant charge, or foam with halogen leak detector to check the flare nut and brazing Carolina Department leaks. Use foam that not
generate ammonia (NH3) in the reaction.
NOTE：
1.When the sealing cap open , between the O-rings stacked in threaded gas release, Anomalous sounds may be generated, this phenomenon is not leaking.
2.This unit is only for the refrigerant R410A. The manifold gauge and the charging hose should be exclusive use for R410A.
3.If vacuum degree of -0.1MPa (756mmHg) is not available, it is considered of gas leakage or entering moisture. Check for any gas leakage once
again. If no leakage exists, operate the vacuum pump for more than one to two hours.
！
●
An excess or a shortage of refrigerant is the main cause of trouble to the unit. Charge the correct refrigerant quantity according
to the description of label at the inside of the manual.
●
Check for refrigerant leakage in detail. If a large refrigerant leakage occurs, it will cause difficulty with breathing or harmful gases would
occur if a fire was being used in the room.

(1)Follow local codes and regulations when select field wires.
(2)Use the wires which are not lighter than the ordinary polychloroprene sheathed flexible cord.(Cord designation H07RN-F).
(3)The wire sizes marked with *1 in the above table are selected at the maximum current of the unit according to the
European Standard,EN60 335-1.

●
Turn OFF the main power switch to the indoor unit and the outdoor unit and wait for more than 3 minutes before electrical wiring
work or a periodical check is performed.
●
Check to ensure that the indoor fan and the outdoor fan have stopped before electrical wiring work or a periodical check is performed.
●
Protect the wires, electrical parts, etc. from rats or other small animals. If not protected, rats may gnaw at unprotected parts and at the
worst, a fire will occur.
●
Avoid the wirings from touching the refrigerant pipes, plate edges and electrical parts inside the unit.
If not do, the wires will be damaged and at the worst, a fire will occur.
●
Install an ELB (Electric Leakage Break)in the power source.
If ELB is not used, it will cause electric shock or fire at the worst.
●
This unit uses an inverter, which means that it must be used an earth leak detector capable handing harmonics in order to prevent
malfunctioning of the earth leak detector itself.
●
Do not use intermediate connection wires, stranded wires(see <Attentions when Connect the power supply wiring>), extension
cables or control line connection, because the use of these wires may cause fever, electric shock or fire.
●
The tightening torque of each screw shall be as follows.
M4: 1.0 to 1.3 N-m
M5: 2.0 to 2.5 N-m
M6: 4.0 to 5.0 N-m
M8: 9.0 to 11.0 N-m
M10: 18.0 to 23.0 N-m
Keep the above tightening torque when wiring work.
●
With tape material along the wire wrapped, sealed wiring holes, prevent the condensed water and insects.
●
Tightly secure the power source wiring using the cord clamp inside the unit.
Note: Fix the rubber bushes with adhesive when conduit tubes to the outdoor unit are not used.
General Check
(1)Make sure that the field-selected electrical components (main power switches, circuit breakers, wires, conduit connectors and
wire terminals) have been properly selected according to the electrical data.
Make sure that the components comply with National Electrical Code (NEC).
Torque (2)Check to ensure that the voltage of power supply is within +10% of nominal voltage and earth phase is contained in the power
supply wires. If not, electrical parts will be damaged.
(3)Check to ensure that the capacity of power supply is enough.
If not, the compressor will be not able to operate cause of voltage drop abnormally at starting.
(4)Check to ensure that the earth wire is connected.
(5)Install a main switch ,multi-pole main switch with a space of 3.5mm or more ,single phase main switch with a space of 3.0mm
or more between each phase. Please use the special three-phase power switch for 3-Phase product.
(6) Check to ensure that the electrical resistance is more than 1 megohm, by measuring the resistance between ground and the
terminal of the electrical parts.
If not, do not operate the system until the electrical leakage is found and repaired.

Trial Run

Trial run should be performed after refrigerant piping,drain,wiring,etc. have finished.
CAUTION
The air-conditioner is provided with a crankcase heater, check to ensure that the switch on the main
power source has been ON for more than 6 hours ahead of power on preheating, otherwise it might
damage the compressor!
Do not operate the system until all the check points have been cleared.
（A） Check to ensure that the stop valves of the outdoor unit are fully opened.
（B）Check to ensure the electric wires has been fully connected.
（C）Check to ensure that the electrical resistance is more than 1 megohm, by measuring the resistance between ground and the terminal
of the electrical parts. If not, do not operate the system until the electrical leakage is found and repaired.
Trial run function identification
Operate remote controller turn ON, then proceed trial run.
Pay attention to the following items while the system is running.
（A） Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the discharge
side are heated higher than 90℃.
（B） DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES). It will cause a serious accident.
Test if the appliance can run well.
Turn off the power after trail run is finished.
Installation of the appliance is generally finished after the above operations are done. If you still have any
trouble, please contact local technical service center of our company for further information.
