
For vertical refrigerant pipe, the distance between supporters should not be exceed 1.5m.
2.6.3.13 Connect the Pipe to Indoor Unit and Outdoor Unit by Using Two Spanners.
NOTE : Connect the copper pipes to the indoor unit first, then connect it to the outdoor unit. You
should first connect the low-pressure pipe, then the high-pressure pipe.

When connecting the flare nuts, apply a thin coat of refriger
ation oil to the flared ends of the pipes.

Align the center of the two pipes that you will connect.

Tighten the flare nut as tightly as possible by hand.

Using a spanner, grip the nut on the unit tubing.

Be sure to use two spanners and proper torque to fasten the nut, too large torque will damage the
bellmouthing, and too small torque may cause leakage. Refer the following table for different pipe
connection.

(kgf.cm) (N.cm)
1/4" (6.35) 144~176 1420~1720
3/8" (9.52) 333~407 3270~3990

NOTE :
E
nsure to wrap insulation around the piping. Direct contact with the bare piping may result
in burns or frostbite.
Make sure the pipe is properly connected. Over tightening may damage the bell mouth and under
tightening may lead to leakage.

After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the
piping together with binding tape.
NOTE : While bundling these items together, DO NOT intertwine or cross the signal cable with any
other wiring.

Overlap the connection pipe insulation material and the indoor unit pipe insulation material. Bind
them together with vinyl tape so that there is no gap

Bundle the piping and drain hose together by wrapping them with vinyl tape over the range within
which they fit into the rear piping housing section.
