Pressure Reducing Valve - resideo Braukmann D160S Instrucciones De Montaje

8. Maintenance
We recommend a planned maintenance contract with
an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
8.1. Inspection

8.1.1. Pressure reducing valve

Interval: once a year
1. Close shutoff valve on outlet
2. Check outlet pressure using a pressure meter when there
is zero through-flow
• If the pressure is increasing slowly, the valve may be
dirty or defective. In this instance, carry out servicing
and cleaning
3. Slowly open shutoff valve on outlet
8.2. Maintenance
8.2.1. Pressure reducing valve
Frequency: every 1-3 years (depending on local
operating conditions)
To be carried out by an installation company
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Loosen slotted screw
• Do not remove slotted screw
Caution !
There is a spring in the spring bonnet. It may cause
injuries if the spring is derailing.
• Make sure tension in compression spring is slak-
kened!
5. Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until it
does not move any more
6. Unscrew spring bonnet
• Use double ring wrench ZR06K
7. Remove slip ring
8. Remove valve insert with a pair of pliers
9. Unscrew filter bowl
• Use double ring wrench ZR06K
10. Remove slotted ring
11. Check that sealing ring, edge of nozzle and slotted ring
are in good condition, and if necessary replace the entire
valve insert
12. Remove filter, clean and reinsert
13. Place O-ring onto filter bowl
14. Reassemble in reverse order
Press in diaphragm with finger before inserting slip ring
Screw in filter cup hand-tight (up to max. 18Nm)
15. Set outlet pressure and adjust setting scale

8.3. Cleaning
Caution !
Do not use any cleansers that contain solvents and/or
alcohol for cleaning the plastic parts, because this
can cause damage to the plastic components - water
damage could result.
If necessary, the filter bowl and the filter can be cleaned.
To be carried out by an installation company or the
operator.
Detergents must not be allowed to enter the environ-
ment or the sewerage system!
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Unscrew filter bowl
• Use double ring wrench ZR06K
5. Remove filter, clean and reinsert
6. Place O-ring onto filter bowl
7. Screw in filter cup hand-tight (up to max. 18Nm)
8. Slowly open shutoff valve on inlet
9. Slowly open shutoff valve on outlet
8.4. Adjusting the setting scale
If the adjustment knob is removed, this setting is lost. A new
setting can be achieved using a pressure gauge.
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Fit pressure gauge
5. Loosen slotted screw
• Do not remove slotted screw
6. Slowly open shutoff valve on inlet
7. Set desired outlet pressure (e.g. 4 bar)
8. Align scale (e.g. 4) in middle of viewing window
9. Retighten slotted screw
10. Slowly open shutoff valve on outlet
9. Disposal
