Check that the low-pressure hose is connected to the low-pressure side of the outdoor unit.
Check that the system has been evacuated to 500 microns. Remove the Vacuum micron
gauge to prevent damage to it.
Open the low pressure and high-pressure valves by winding them out anti clockwise until
seated.
The low-pressure gauge should read approximately 150 PSI.
