Connecting The Piping; Electrical Wiring - Haier AC12CS1ERA Manual De Instrucciones

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.

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

ELECTRICAL WIRING

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.

Insulation
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.
