9-10-4. Check and Test Operation
•Pressure of R410A is approx. 1.6 times of that of R22. If installation work is incompletely finished, a gas leakage may occur at the cases such as pressure rise during operation.
Therefore, be sure to test the piping connections for leakage.
•Check the flare nut connections, valve stem cap connections and service port cap fittings for gas leak with a leak detector or soap water.
