It requires that the Class wire and Class wire should be separated.
Procedure :
1. Connect the power supply wire to the solenoid valve kit,
using the Class wire.
5. Installation to the Solenoid Valve Relay Kit
Install the solenoid valve relay kit into the indoor unit and fix it using a Philips-head screwdriver. See the
diagram in the section of "6. Electrical Wiring Diagrams".
Do not install outside the building and the area where the water is splashed. Failure to do
so could result in product or property damage.
2. Connect the solenoid valve kit to the solenoid valve relay kit,
using the Class wire.
3. Connect the solenoid valve relay kit to the indoor unit,
using the supplied connect wire.
4. The left-over wires connected to the solenoid valve relay kit
should be tied up in a bundle of wires by the supplied wire
holder not to leave the wires loose as shown in the diagram
at right.
