Hi,
I have a split 12,000btu AC unit running on R407c gas. It was a DIY install last year.
When first installed it worked perfectly.
I had a small leak where one of the connections which was not done up tight enough. Once I noticed a mark on the wall where the gas had leaked and left a mark I tightened up the connection and since no more gas has leaked.
My problem is the AC unit is no longer as cold as when it was first installed.
I have done a lot of research on how to top up the gas and understand I need to get a set of gauges with the blue being connected to the low pressure (Large pipe) and the red to the High pressure (Smaller pipe) leaving me with the yellow pipe to connect to the bottle.
My question is how much gas do I put in?
I take it I connect the gauges and take a reading then add enough gas to fill the system back up?
Can anyone help me with what pressure I need to have?
Do I need to run the unit before filling up with gas like the descriptions seem to indicate with cars?
Any help or advice would be gratefully received
Kind Regards
Dannny
