Connect the solenoid valve kit to the solenoid valve relay kit,
using the Class wire shown in Table 19. (Fig. 2, Fig. 3)
Connect the solenoid valve relay kit to the indoor unit, using
the supplied connecting wire. (Fig. 1, Fig. 2)
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. (Fig. 2)

(4)
Cut the wire end with cutting pliers, then strip the insulation to expose the stranded wiring about 25/64" (10 mm) and
tightly twist the wire ends. (Fig. 4)
Using a Phillips head screwdriver, remove the terminal screw(s) on the terminal board.
Using a ring connector fastener or pliers, securely clamp each stripped wire end with a ring pressure terminal.
Place the ring pressure terminal, and replace and tighten the removed terminal screw using a screwdriver. (Fig. 5)
