Figure 4-58 Connecting indoor unit stop valves
CA UTION
Wrap the stop valves of the liquid pipe and gas pipe, and the connecting pipe
for the stop valves with thermal insulation foam (thickness: 5 mm).
3. Tighten the pipe nut, needle valve nut, and rear cover nut based on the
torque listed in Table 4-8.
NO TICE
Ensure that you tighten the nut to the specied torque. The failure torque for
the nut of the liquid pipe stop valve is 70 N·m and that for the nut of the gas
pipe stop valve is 100 N·m. The torque greater than the failure torque will
damage the screw thread.
