Þre ignition.
Ensure that drainage piping is connected properly.
If the drainage piping is not connected properly, it may
cause water leakage which will dampen the furniture.
Do not overcharge the unit.
This unit is factory pre-charged.
Overcharge will cause over-current or damage to the
compressor.
Ensure that the unit’s panel is closed after service or
installation.
Unsecured panels will cause the unit to operate noisily.
Sharp edges and coil surfaces are potential locations which
may cause injury hazards.
Avoid from being in contact with these places.
Before turning off the power supply, set the remote
controller’s ON/OFF switch to the “OFF” position to prevent
the nuisance tripping of the unit. If this is not done, the unit’s
fans will start turning automatically when power resumes, posing
a hazard to service personnel or the user.
Do not operate any heating apparatus too close to the air
conditioner unit. This may cause the plastic panel to melt or
deform as a result of the excessive heat.
Do not install the units at or near doorway.
Do not operate any heating apparatus too close to the air
conditioner unit or use in room where mineral oil, oil vapour
or oil steam exist, this may cause plastic part to melt or
deform as a result of excessive heat or chemical reaction.
When the unit is used in kitchen, keep ßour away from going
into suction of the unit.
This unit is not suitable for factory used where cutting oil
mist or iron powder exist or voltage ßuctuates greatly.
Do not install the units at area like hot spring or oil reÞnery
plant where sulphide gas exists.
Ensure the color of wires of the outdoor unit and the terminal
markings are same to the indoors respectively.
IMPORTANT: DO NOT INSTALL OR USE THE AIR
CONDITIONER UNIT IN A LAUNDRY ROOM.

Piping Works And Flaring Technique
Do not use contaminated or damaged copper tubing. If any pipings, evaporator or condenser had been exposed or had been
opened for 15 seconds or more, the system must be vacuumed. Generally, do not remove plastic, rubber plugs and brass
nuts from the valves, Þttings, tubings and coils until it is ready to connect suction or liquid line into valves or Þttings.
If any brazing work is required, ensure that the nitrogen gas is passed through coil and joints while the brazing work is
being done. This will eliminate soot formation on the inside walls of the copper tubings.
Cut the pipe stage by stage, advancing the blade of the pipe cutter slowly. Extra force and deep cut will cause more distortion
on the pipe and thus extra burr. See Figure I.

Remove burrs from cut edges of the pipes with remover
as shown in Figure II. This will avoid unevenness on the
ßare faces which will cause gas leak. Hold the pipe on top
position and burr remover at lower position to prevent metal
chips from entering the pipe.
Insert the ßare nuts, mounted on the connection parts of
both the indoor unit and outdoor unit, into the copper
pipes.
The exact length of pipe protruding from the top surface
of the swaging block is determined by the ßaring tool.
Refer Figure III.
Fix the pipe Þrmly on the swaging block. Match the centers
of both the ßare die and the ßaring punch, and then tighten
the ßaring punch fully.
Piping Connection To The Units
Align the center of the piping and tighten the ßare nut
sufÞciently with Þngers. Refer Figure IV.
Finally, tighten the ßare nut with the torque wrench until
the wrench clicks.
When tightening the ßare nut with the torque wrench,
ensure that the tightening direction follows the arrow
indicated on the wrench.
The refrigerant pipe connection are insulated by closed
cell polyurethane.

Do not connect wires of the
same gauge to one side.
Do not connect wires
of different gauges.
All wires must be Þrmly 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 Þxed 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 R410Ain 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 ßare 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, ßare 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 Þre, 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. ConÞrm 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 ßare
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.
