Installation Procedure

CONNECTING THE PIPING

1.Flare processing

(1)Cut the connection pipe with pipe cutters so that the pipe is not deformed.

(2)Holding the pipe downward so that cuttings cannot enter the pipe, remove the burrs.

(3)Remove the flare nut from the indoor unit pipe and outdoor unit and assemble as shown in Table1 and insert the flare nut onto the pipe, and flare with a flaring tool.

(4)Check if the flared part "L" (Fig.1) is spread uniformly and that there are no cracks.

Model	Pipe	Diameter of pipe	Dimension A (mm)
AC12CS1ERA	Liquid pipe	6.35mm (1/4")	1.0~1.2
	Gas pipe	9.52mm (3/8")
AC18CS1ERA	Liquid pipe	6.35mm (1/4")	1.0~1.2
	Gas pipe	12.7mm (1/2")
AC24CS1ERA	Liquid pipe	9.52mm (3/8")	1.4~2.2
	Gas pipe	15.88mm (5/8")

2. Bending pipes

The pipes are shaped by your hands. Be careful not to collapse them.

Connect wiring to the terminal blocks

A. For solid core wiring (or F-cable) (Fig.A)

(1)Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of the exposed solid wire.

(2)Using a screwdriver, remove the terminal screw(s) on the terminal board.

(3)Using pliers, bend the solid wire to form a loop suitable for the terminal screw.

(4)Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal screw using a screw driver.

B. For strand wiring (Fig.B)

(1)Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of the exposed strand wiring.

(2)Using a screwdriver, remove the terminal screw(s) on the terminal board.

(3)Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.

(4)Position the round terminal wire, and replace and tighten the terminal screw using a screw driver.

Fix connection cord and power cable at the cord clamp

After passing the connection cord and power cable through the insulation tube, fasten it with the cord clamp, as shown right.

Use VW-1, 0.5 to 1.0 mm thick, PVC tube as the insulation tube.
