⚫
After installation, check the piping, wiring, length
of connection wires and power supply wire
inserted in the terminal board and their polarities
(or signs) are correct.
⚫
This product will absorb the noises produced by
static electric charge, be sure to connect the
earth wire.
⚫
To avoid current leakage, be sure to install a
"high sensitivity, high speed earth leakage circuit
(for inverter)."

Installation of a remote controller holder
⚫
The remote controller can be attached to the
wall, column or table by using the remote
controller holder.
⚫
If the remote controller is to be operated on the
holder, make sure that the unit can receive the
signals sent from the position of remote
controller before determining the position to be
installed. The unit will react with a "beep" sound
when receiving a signal. The signals can be
attenuated due to the fluorescent tube, so when
determining the position of installation, even if it
is daytime, the light must be turned on.
⚫
Attach the remote controller with wood screws
at the suitable position. (Do not attach it to the
places where it can expose to direct sunlight
and places where strong heat can generate)
⚫
Insert the remote controller in its holder. (As
indicated by the arrow in the diagram)

⚫
As R410A is mixed refrigerant, if charged in gas
phase the components of refrigerant will alter,
which will affect normal working of the system. So,
be sure to charge refrigerant in liquid phase.
⚫
Verify indications on the refrigerant cylinder. If the
refrigerant cylinder does not contain a siphon, the
cylinder must be positioned upside down; if it
contains a siphon, the cylinder must be positioned
upright.
⚫
To ensure a correct refrigerant recharging quantity,
use an electronic scale.
5
Maintenance operation
⚫
When refrigerant recycle or outdoor-unit-only
operation is carried out, please turn off the breaker
firstly, then open the switch and wait 1 minute at
least, and then press the service switch for 1
second at least on the main PCB of the outdoor
unit to start the unit operation.
⚫
Press the service switch again for 1 second at least
to stop unit operation.
⚫
After unit stoppage, please turn off the breaker, and
then turn on it again to return to the normal state
mode.
⚫
To protect the compressor, please do not operate
the unit for more than 5 minutes when the service
valve is closed.
