Had my chasis a/c switched to R134 3 years ago. Takes 38oz of R134
to charge it.

The update to R134 consisted of replacing the oil, the dryer and the
expansion valve. Recharge with 38oz R134 and works great.

The spring has always required a recharge. This year my machine
recovered 12oz. while e-vacuating. Recharged with 38oz of R134 and
it has worked GREAT all summer. My low side pressure is 20-40psi and
high side has reached 280psi(at an outside temp of 85)

I am no expert, so I don't know if those are the correct pressures,
it does work good at those pressures though.

The chasis air does a very good job of cooling the pilot and co-
pilot, keep it working.

We have introduced the green dye into the system the last 2 years.
Have not been able to find a leak. The leak must be either outside
in the weather or in a spot I can't see.

Fortunately, we have a/c equipment that is too SIMPLE to use, its
virtually automatic. Just tell it how much oil and how much R134 you
want in the system, and it automatically starts a vaccum, stops and
checks for a loss of vaccum(about 10 minutes) then starts
introducing R134 and oil until the amount specified is reached.
Pretty easy.

It's easy to spot and will show a leak easily. It's normal to add
freon bi-annually.

Jay,

What A/C service equipment are you using and where did you get it?

Thanks.

(Now that my system has been serviced and recharged, I expect to be
keeping it serviced myself.)
