Installation Inspection
Step 4.1 Performing the gas leak tests
1 Before inspecting the leakage, use a torque
wrench to close the cap for the stop valve. (Comply
with a tightening torque for each size of the
diameter, and tighten the cap firmly to prevent
any leakage.)
2 Insert inert gas into the pipes connected to indoor
and outdoor units.
3 Test leakage on the connection parts of the indoor
and outdoor units with soap lather or liquid.
