Wiring
●
Connect the 9P connector coming from the solenoid valve kit
through the power inlet of the indoor unit to the 9P connector
(red) of the Solenoid Valve Control PCB (sold separately) as
shown in Fig. 3-13. Accessory wire length is 5 m.
●
In case the wire is not long enough, cut the wire halfway and
connect additional wire (field supply) as an extension using a
terminal box (field supply). Additional wire must be “H05VVF
0.5 mm
2
” or “60227 IEC53”.
●
Anchor the cabtyre cable using the binding bands inside the
unit. Do not route the cabtyre cable through the same wiring
conduit as the remote controller wiring or inter-unit control
wiring.
●
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons
in order to avoid a hazard.
NOTE
The wire should be fixed with the clamp inside the indoor unit.

or more
(300 V or more)
●
Grounding should be done between the indoor unit and
solenoid valve kit.
The following figure applies if required wire length is less
than 5 m.
