The manifold gage reads suction in inches of mercury.
An inch is 24.5 MM
A micron gage reads in 1/1000 of a milimeter, or 1/25,400 of an inch. A refrigeration guy will want to get down to 500 or fewer microns. Your manifold gage won't read that, accurately.
Do a google search on "micron gage" and see what you learn.
Point being, what the manifold states, is worthless in a vac.
Anyone got a camcorder to watch this guy install his shit? LOL
Maybe we'll get lucky and they will show it on "Americas Funniest Videos". And with the $10,000 prize he can get a new A/C system.
