how to properly charging system
hi
after vacuuming system
if i want to charge it
what is the best way
as example
if i have 2 ton window type ac and r22
some people say
i must charge it with liquid in the beginning then after turning it i must charge it with vapor only
other say i must charge it with vapor when unit is off
then after turning on it i can charge with liquid and vapour
so what is the properly way to charge ac
others say
Power consists not in being able to strike another but in being able to control oneself when anger arises

Re: how to properly charging system
sorry the link you put is dazed me
ok if you dont mind
i am doing this charging by this way
when unit is off i charge unit with liquid only by weight through suction line
then after turning on unit its suction pressure is 60 or 70 psi
and i found no need to add r22 because suction line is being very cold which mean unit has required quantity of *****
what is your opinionPower consists not in being able to strike another but in being able to control oneself when anger arises

Re: how to properly charging system
if you can fit gauges to both sides of the system let liquid in the high side until you cannot get any more in-observe the weight charged- system will stop taking in liq,shut gauges and start system- open low side and charge vapour slowly to finalise the charge- if needed you can add liquid in the suction line to get all the charge in but do it slowly .
