Table 1CONNECTING 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 are nut from the indoor unit pipe and outdoor unit and
assemble as shown in Table1 and insert the are nut onto the pipe, and
are with a aring tool.
(4) Check if the ared 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.
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.
