looked at the download info on the aircore unit but ther was no mention of the the size of the restrictor.i'll check more sites and maybe find what i'm looking for.mr. cheap came the smorning and cleaned out the mainline drain. that's done with.took the cleaner back to home depot for a refund. back to the restrictor valve in small line in outside unit. if the arcoaire unit has different size restrictor than the origanal comfortmaker .067 could this affect the temperture output.
