NO, no solvent may be used to clean a compressor.
The compressor must be disconnected from the circuit in order to prevent a loss of oil which could result in damage to moving parts. The control and expansion valves as well as the filters/driers must also be disconnected or removed.
In general, you can estimate the quantity of Nettogaz GC1 necessary as two or three times the amount in the refrigerant fluid (dependent on the structure of the circuit).
To evaluate the quantity of the product to be used, you can estimate the approximate quantity of GC1 contained in 1 linear metre
v ¼' : approx. 20 g
v 3/8' : approx. 60 g
v 1/2' : approx. 120 g
v 5/8 : approx. 200 g
v ¾' : approx. 300 g
v l7/8' : approx. 420 g
v 1"1/8 : approx. 710 g
v 1"3/8 : approx. 1070 g
Its boiling point of +20°C to +24°C makes it easily extractable. The possible remainders of Nettogaz GC1 are removed by flushing with anhydrous nitrogen.
