The hot water temperature can be changed by adjusting the temperature dial on the bottom surface of the unit. (The dial adjusts the temperature typically between 95°F and 131°F. The factory sets the temperature dial at the lowest position.) • There are internal safety thermal cut-outs which will operate if the unit overheats. If a thermal cutout trips, then it must be reset by a qualified electrician. • If the unit has been used recently, run the water through for a few seconds to let the temperature settle down. You may initially get a short burst of very hot water from the unit. • If a second outlet connected to the unit is also turned on, the hot water will be shared between the two. Installing the PowerStar WARNING IMPORTANT Do not install the unit in a room where there Read entire instructions. is a chance of freezing. Check the pressure of the main water supply. To operate correctly, the unit needs the following running pressures : Minimum: 15 psi (1 Bar) Maximum: 150 psi (10 Bar) Securing the unit to the wall Diagram 1 A E115 Unit AE125 Unit WARNING The unit must only be installed in the orientation shown in Diagram 1, i.e., mounted in a vertical position with the water fittings located at the bottom of the unit.
