Hi
i got a split as heatpump with burn out compressor
Its R22 24000 BTU
after removing the compressor
i flushed evaporator and condenser and capilary tube with paint thinner (as i do in usually)
then flushed them with plenty of R22 and
replaced the filter
I installed a LG rotary compressor with same specification of the old compressor
after making vacuum for 30 minutes
i charged the system according to Gauge reading not by weight
so the compressor wasn't work normally
as the liquid line kept icing
so i removed the compressor from the unit
then welded a service valve to to its discharge pipe
then i attached the manifold gauge and closed it
i switched on the compressor
so when its reached 300 psi
its opened internal safety valve

so i realesed the air from it
then i switched it on when its reached 300 psi
the compressor upper cover get inflated








then i opened the compressor
