13. Loosen the center hose connection on the manifold gauge for a few seconds (if there is a purge valve on the manifold gauge push this instead) to
allow the air in the center manifold hose to escape using the refrigerant pressure.

CAUTION: When filling with the engine running, do not open the high pressure side valve. Always fill from the low pressure side.
