Recently I had my two heating/AC systems replaced with Rheem units.
During the installation I noticed that some Freon escaped during the
charging operation of the new A/C systems. The condenser units are
RAND-24JAZ models, R22, SEER 13 units.
The installation information states the Service Valve is "NOT" back
seated on these units. I have read of some valves (King Valves I
believe), that cut off the input of coolant when the valve is backed
out. When they removed the hoses, they did so rapidly so as to lose a
minimum of Freon. My question is: Is it possible that these units were
made so that escaping Freon cannot be stopped when attaching and
disconnecting the hoses for charging, or was the installer unaware of
how to do it without allowing the escape?
This is not a major problem as I hope the new units serve me well as
the old ones had done, but it is a curiosity. Thanks.
