• 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 flare valve is different from that of R22.

same gauge to both side.
SPECIAL PRECAUTIONS WHEN DEALING WITH R410A UNIT
Electric wire
Do not connect wires of the
same gauge to one side.
• 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.
