CAUTION
For low-noise operation, it is necessary to install the optional
•
“External control adaptor for outdoor unit”.
For details, see the installation manual attached to the
adaptor.
Caution on the wiring length between units
Make sure to observe the restrictions below. If they are
not observed, transmission error may occur.
Maximum wiring length: 3280 ft.
Cautions on the wiring between units
Never connect 208/230V to the terminal block for the trans-
•
mission wiring.
Doing so will break the entire system.
The transmission wiring from the indoor unit must be con-
•
nected to the F1/F2 (TO IN/D UNIT) terminals on the PC
board in the outdoor unit.
∗
Make sure to use sheathed two-core cables of AWG18-16 in
the wiring shown above.
∗
All cables used in the wiring between the units should
be procured on the site.

dure
”.
Connection of transmission wiring and tightening of screws:
3.
Refer to “
7-4 Transmission wiring connection proce-
dure
”.
Freezing connection of refrigerant piping
4.
Refer to “
6. REFRIGERANT PIPING WORK
”.
Piping size and heat insulation:
5.
Refer to “
6-1 Selection of piping material
”, “
6-5 Heat
insulation of piping
”.
Check of stop valve:
6.
Confi rm that the stop valve is open on both the liquid line
and gas line.
Record of amount of additional refrigerant:
7.
Record the amount on the label stuck on the back of the
front panel.
Measurement of insulation in main power circuit:
8.
Use the megatester for 500 V.
•
Do not use any megatester for low voltage electric circuits
•
except 230 V.
(Wiring between the outdoor unit and the indoor unit)
CAUTION
<To piping technician>
Make sure to open the stop valve after fi nishing the piping
•
work.
(Operating the air conditioner with the stop valve shut may
damage the compressor.)
TEST RUN PROCEDURE
9.
A crankcase heater is mounted for smooth startup. Make
sure to turn on the power 6 hours before starting opera-
tion for supplying the power to the crankcase heater.
WARNING
Make sure to close the front panel before leaving the
•
outdoor unit in the power ON status.
To avoid injury, always make sure that the overcurrent
•
protective device on the power supply panel of the installa-
tion is switched off before doing any work.
Cautions before turning on the power
Put the insulating cover securely onto the control box.
•
After turning on the power, check the settings and LED
•
indicators on the PC board (A1P) in the outdoor unit
through the opening of the insulating cover.
Power on and check operation
9-1
Make sure to perform the check operation after installation.
•
(If the air conditioner is operated using the indoor remote
controller without performing the check operation, the mal-
function code “U3” is displayed in the indoor remote control-
ler, and normal operation is disabled.)
