ƴ.1.3 Connecting the Pipe at the Indoor Unit Side
Detach the caps and plugs from the pipes.
When connecting the pipe to the unit or removing it from the unit, please do use both the spanner and
the torque wrench (Figure 3-3-4).
When connecting, smear both inside and outside of the flare nut with refrigeration oil, screw it hand
tight and then tighten it with the spanner.
Refer to Table 3-3-1 to check if the wrench has been tightened properly (too tight would mangle the nut
and lead to leakage).
Examine the connection pipe to see if it leaks, then take the treatment of heat insulation, as shown in
the Figure 3-3-4.
Use the medium-sized sponge to insulate the coupler of the gas pipe.

CAUTION!
1. To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of 150mm (5-7/8inch)
or over.
2. If the pipe is bent repeatedly at the same place, it will break.
