[. . . ] ⷠIf, for compelling reasons, more elbows or a greater length becomes necessary, then the entire discharge line must be designed to a larger nominal width. More than 3 elbows, as well as lengths over 4m are not permitted! ⷠThe discharge line must be installed with an incline!Install safety group in the cold water line o Note flow direction o Install without tension or bending stresses 1 Setting outlet pressure Set outlet pressure min. Loosen slotted screw o Do not remove slotted screw 5. Slacken tension in compression spring o Turn control handle to the left (-) until it does not move any more 6. Turn control handle until the setting scale shows the desired value 8. DIN 1988, Part 8 specifies that the following operations be carried out regularly. 1 Pressure reducing valve Interval: once a year 1. Check back pressure using a pressure meter when there is zero through-flow o If the pressure is increasing slowly, the valve may be dirty or defective. In this instance, carry out servicing and cleaning 3. Open check valve o Until the pressure is released, some water will flow out of the check valve. After a short period of time the water flow should stop. If the water continues to drip or run, then the backflow preventer must be replaced - see servicing of backflow preventer 3. 3 Safety valve Frequency: every 6 month 1. Actuate lifting device multiple times, if necessary initiate repairs 9. 1 Pressure reducing valve Frequency: every 1-3 years (depending on local operating conditions) To be carried out by an installation company 1.
