Fan coil unit inside room need to be dismantled from pipings after the coolant is retrieved back into the compressor ? I am refering to those split unit aircon type.
How do yuo spray CX448 onto fins ? Use a plastic container with a spray like those for psraying flowers ok ?
If we just spray diluted CX448 but did not rinse, what is longer-term problems ? Compressor outside apartment hence canot reach.
