hi,
I've today been asked to install 2 "DIY" units, looking through the destructions and the method suggested for removing air and moisture is bizzarre, apparently i dont need to vac out or pressure test, but couple up the pipes (not sealed quickfits but pre flared copper ends)open the lp valve from the condenser for 6 seconds then close it then check for leaks with soapy water, then (taken from instructions)
push in the ‘tyre inflator’ style valve on the T-branch valve (SIDE OF BOTTOM VALVE) for 4 – 5 seconds using a screwdriver or similar, to expel the air in the pipe-work.
This cant be legal can it???
