Re: minimum length pipe run between indoor and outdoor on mitsubishi heavy industry
with some units the short pipe run causes water droplets from the evap surface ; if you retired you may not need to know the manufactures brand, if you think the liquid remains in the liquid receiver or the condenser, with certain units that does not comply, what i ment was the distance to be less than 2m.
thanks for the reply????????????????

Re: minimum length pipe run between indoor and outdoor on mitsubishi heavy industry
only small splits under 5kw highlight a minimum of 1.5mtr run- shouldnt matter on a mhi as the lev will control the superheat , best practice is to RTFM
