Commissioning; Setting Outlet Pressure; Maintenance - Honeywell MiniPlus-FK FK06-AAM Installationsanleitung

8. Commissioning

8.1 Setting outlet pressure

Set outlet pressure min. 1 bar under inlet pressure.
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
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. Slowly open shutoff valve on inlet
7. Turn control handle until the setting scale shows the
desired value
8. Retighten slotted screw
9. Slowly open shutoff valve on outlet

9. Maintenance

We recommend a planned maintenance contract with
an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
9.1 Inspection
9.1.1 Filter
Frequency: at least every 2 month (depending on local
operating conditions
• Non-compliance can lead to the filter becoming
blocked This results in a drop in pressure and
decreasing water flow
• The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines
has no influence on function or the way the filter
works
To be carried out by an installation company or the
operator.
Filtered water can be drawn during rinsing.
If rinsing is into a container, then a suitable container
must first be put underneath.
1. Open the ball valve by turning the rinse knob
o Rinse knob must be vertical
2. Close the ball valve after approximately 15 se-conds
A longer reverse rinse period may be neces-sary if the
filter is very dirty (Replace filter mesh see Mainte-
nance)
9.1.2 Pressure reducing valve
Interval: once a year
1. Close shut off valve on outlet
2. Check back pressure using a pressure meter when there
is zero through-flow
Honeywell GmbH
GB
o 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
9.2 Servicing
9.2.1 Pressure reducing valve
Frequency: every 1-3 years (depending on local opera-
ting 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
o Do not remove slotted screw
Caution !
There is a spring in the spring bonnet. It may cause inju-
ries if the spring is derailing.
• Make sure tension in compression spring is slak-
kened!
5. Slacken tension in compression spring
o Turn control handle to the left (-) until it does not move
any more
o Do not turn in too far!
6. Unscrew spring bonnet
o Use double ring wrench ZR06K
7. Remove slip ring
8. Remove valve insert with a pair of pliers
9. Unscrew filter bowl
o Use double ring wrench ZR06F
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.Reassemble in reverse order
Press in diaphragm with finger before inserting slip ring
Screw in filter bowl hand-tight (without tools)
13.Set outlet pressure and adjust setting scale
9.3 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. Loosen slotted screw
o Do not remove slotted screw
5. Slowly open shutoff valve on inlet
6. Set desired outlet pressure (e.g. 4 bar)
7. Align scale (e.g. 4) in middle of viewing window
8. Retighten slotted screw
9. Slowly open shutoff valve on outlet
