between the indoor and the outdoor units.
Remove service port cap of the stop valve A and connect gage manifold valve and vacuu

p
ump to it.
Run the vacuum pump for more than 15 minutes and at this time confirm that the pressure
gage indicates -0.1Mpa(-76 cmHg).
Stop pump and keep the pressure for one or two minutes. Make sure the pressure is no
change(if the pressure is changed to high, there is some leakage for the pipe connection).
Remove gage manifold valve quickly from the service port of the stop valve A.
full open the stop valvesA on gas and liquid pipe sides.
Total pipe length is in the range:
