1. Fit an approved stop valve (4) on the cold water side as required by the
applicable regulations (1.3 "Regulations") .
2. The maximum working pressure of the water heater is 8 bar. Because the
pressure in the water pipe at times can exceed 8 bar, you must fit an
approved pressure-reducing valve (1).

4. Fit an expansion valve (15) and connect the overflow side to an open waste
water pipe.
