Next, mount the valve cap and tighten it with a torque wrench (the cap needs to be tightened with the torque of 170 ibs.·in. (200 kg·cm)). This process is very important to prevent gas from leaking from the system.

(12)Test run the air conditioner. (See next page.)

(13)While the air conditioner is running, apply liquid soap to check for any gas leaks around the service valves or caps.

(14)If there is no leakage, stop the air conditioner.
