Just a general FYI for those who don't know since we're getting into A/C
season and questions- The diagram in the Bentley on 87.2 has the labels for
the high and low pressure refrigerent lines (numbers 10 & 11) reversed.
This could be very dangerous in that you could wind up pressurizing your
refrigerant can and blowing it up (if you followed the diagram and tapped
into the wrong line), along with whatever else is unfortunate enough to be
nearby.
