Attach insulation sleeve

Round crimp-style terminal

Electric wire

Connect wires of the 
same gauge to both side.

Do not connect wires of the 
same gauge to one side.

Do not connect wires 
of different gauges.

All wires must be 

fi

 rmly connected.

Make sure all the wire do not touch the refrigerant pipings, compressor or any moving parts.
The connecting wire between the indoor unit and the outdoor unit must be clamped by using provided cord anchorage.
The power supply cord must be equivalent to H07RN-F which is the minimum requirement.
Make sure no external pressure is applied to the terminal connectors and wires.
Make sure all the covers are properly 

fi

 xed to avoid any gap.

Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching 
to the indication on terminal block. (Refer to the wiring diagram attached on the unit).

Use the correct screwdriver for terminal screws tightening. Unsuitable screwdrivers can damage the screw head.
Over tightening can damage the terminal screw.
Do not connect wire of different gauge to same terminal.
Keep wiring in an orderly manner. Prevent the wiring from obstructing other parts and the terminal box cover.

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 conditioner 
which designed to operate with R410A.
POE or PVE oil is used as lubricant for R410A 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 R410A system too long 
to moist air. Residual POE or PVE oil in the piping and 
components can absorb moisture from the air.
To prevent mischarging, the diameter of the service port on 
the 

fl

 are valve is different from that of R22.

Use tools and materials exclusively for refrigerant R410A. 
Tools exclusively for R410A are manifold valve, charging 
hose, pressure gauge, gas leak detector, 

fl

 are 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 correctly. 
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 

fi

 re, a poisonous gas may occur.

When installing or removing an air conditioner, do not allow 
air or moisture to remain in the refrigerant cycle.

SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT

Vacuuming is necessary to eliminate all moisture and air from the system.

Vacuuming The Piping And The Indoor Unit

The indoor unit and the refrigerant connection pipes must 
be air-purged because the air containing moisture that 
remains in the refrigerant cycle may cause malfunction of 
the compressor.

Remove the caps from the valve and the service port.
 Connect the center of the charging gauge to the vacuum 
pump.
 Connect the charging gauge to the service port of the 3-
way valve.

VACUUMING AND  CHARGING

 Start the vacuum pump. Evacuate for approximately 
30 minutes. The evacuation time varies with different 
vacuum pump capacity. Con

fi

 rm that the charging gauge 

needle has moved towards -760mmHg.

Caution

 If the gauge needle does not move to -760mmHg, be sure to 
check for gas leaks (using the refrigerant detector) at 

fl

 are 

type connection of the indoor and outdoor unit and repair 
the leak before proceeding to the next step.
 Close the valve of the changing gauge and stop the vacuum 
pump.
