8.2 Setting raw water inlet pressure on the
pressure regulator
Raw water inlet pressure must be at least 2 bar and must not exceed
a maximum of 6 bar .
Factory setting of the pressure regulator is 6 bar.
In case of the permeate to be blended with raw water, raw water
inlet pressure must be 1 bar beyond permeate pressure. Perme-
ate pressure can be monitored by means of pressure gauge
PI110.60.
Figure Step Action
1 Close inlet and outlet shut-off ball
valves.
2 Depressurize outlet side. This may be
achieved by e.g. loosening the outlet
pressure gauge. Pressure gauge
should then be tightened again.
3 Release the compression spring:
Turn the adjustment handle coun-
terclockwise (-) as far as it will go.
4 Slowly open inlet shut-off ball valve.
5 Turn adjustment handle clockwise (+)
until pressure gauge shows the pres-
sure desired.
6 Slowly reopen outlet shut-off ball valve.
