• The table above shows the electrical wire sizing for different connection cables. If the length of the cable is

more than 2m, use cable with bigger size.

• The figures shown in the table are for information purpose only. They should be checked and selected to

comply with the local/national codes of regulations. This is also to the type of installation and conductors

used.

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 conditioner which designed to operate with R410A.

• POE 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 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.

• Use tools and materials exclusively for refrigerant R410A. Tools exclusively for R410A are 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

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 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.
