Installation notes
On the dual flow models (AH220DFM & AH222DFM), these work best if the hot and cold water feeds are the same pressure. If the pressure of the cold supply is higher than the hot supply, then the mixed water will be cold. Therefore, with a typical gravity-fed hot water supply, we recomend that the fit an in-line service valve on the cold supply to reduce the pressure.
