FIrst would like to say what a great forum,
This is my first entry, so sorry if i mess up !

ex Hotpoint engineer of 24 years, always done fridges/freezers,
but only the electrical side of things till last year for which i now involve myself in the refrigerant cycle.

Im converting a fridge/freezer that is R12 to R134a,
Thats a new R134a compressor and dryer.

The unit.. R12 specifies 280grams, not sure how much R134a to charge ????

Thanks for all info.
