Warning..................................................
Products under pressure can cause injury to human
beings and damage to property.
 Before carrying out installation and maintenance
work, switch off the compressed air supply.
 Use shut-off valves in the compressed air supply
tubing for exhausting the system.
Note......................................................
Fitting and commissioning to be carried out only by
qualified personnel in accordance with the operating
instructions.
This product is designed to be operated with com
pressed air only. The product is not suitable for use
with other media (fluids or gases).
With controllers without secondary venting (only
applies to MS9--OS):
Due to the design of these controllers it can result in
the output pressure p2 increasing to the maximum
operating pressure p1 when there is no consumption at
the output. When using a regulated device a small
permissible internal leak without air consumption also
leads to an increase in pressure at p2 and must be
considered in the design phase.

Filter regulator valve MS9-LFR, en............................
Pressure regulator MS9-LR,
Filter MS9-LF, water separator MS9-LWS
1 Application
The filter regulator valve MS9-LFR and the pressure
regulator MS9-LR are designed to regulate compressed
air in the subsequent line to the set output pressure p2.
The MS9-LFR/LR smoothes out fluctuations in pressure
here. The output pressure p2 can be set within the
pressure regulating range (è Technical data chapter)
independently of the input pressure p1.
The filter regulator valve MS9-LFR and the filter MS9-LF
with centrifugal separator remove dirt particles and
condensate from the compressed air blown through it,
while the water separator MS9-LWS removes condensate.

Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Improper handling can result in malfunctions. Make
sure that the following specifications are always
observed:
 Compare the maximum values specified in these
operating instructions with your actual application (e.g.
operating media, pressures, temperatures, flow rates).
 Comply with the regulations of the trade association,
the German Technical Control Board or relevant national
regulations.

3 Installation
3.1 Mechanical
Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Information about mounting module connectors,
sub-bases and mounting brackets can be found in the
operating instructions enclosed with the relevant
accessories.
 Note the direction of flow from 1 to 2.
The numbers 2 on the product housing serve as an
orientation (èFig. 2).
 Place the MS9-LFR/LF/LWS with sufficient space below
the filter bowl (min. 150 mm).
 Adjust the MS9-LFR/LF/LWS standing vertically (± 5°).
Direct mounting of an individual MS9--¾/1 with fasten
ing screws
1.Press all protective caps 3 forwards out of the sub-
base (è Fig. 3). To do this, push a narrow object
through the rear opening of the sub-base.
2.Fasten the individual device with four fastening screws
4 of size M6 and a minimum length of 90 mm
(è Fig. 4). The distance between the holes is 90 mm in
width and 66 mm in height.
Assembly with one or several already available service
units of the same series (è Fig. 5)
1.Dismantle the existing service unit string depending on
the planned location of the device within the string.
If the device is to be installed at the beginning or end of
the service unit string:
– Disconnect the compressed air line from the service
unit string or
– remove the sub-base from the service unit string.
If the device is to be fitted between two service units in
the service unit string:
– Remove the module connector MS9-MV 5 between
the two service units by loosening the screws.
2.Mount the device in the desired location.
3.Place the module connectors MS9-MV 5 in the grooves
of the MS9-LFR/LR/LF/LWS and the adjoining service
unit. There must be a seal between the service units.
4.Fasten the module connectors MS9-MV with two
screws.
5.Fit the removed parts and devices from step 1 together
into a service unit string again.
3.2 Pneumatic
If using screw connectors:
 Note the screw-in depth of the connecting thread.
Max. screw-in depth [mm]
ISO 228 NPT

MS9-...-AGG/AGH: 31.5 MS9-...-AQU/AQV: 31.5
 Screw the connectors into the pneumatic connections
using a suitable sealing material.
For MS9-LR--PO (è Fig. 6):
 Screw the connector into the pneumatic connection
12 in the cover 7 using suitable sealing material.
During installation make sure no dirt particles enter the
device.
4 Commissioning
Setting the output pressure on the MS9-LFR/LR
1.Pull the rotary knob upwards away from the housing
(ifnecessary, remove padlock and push in the unlocking
device 1 è Fig. 2).
2.Turn the rotary knob completely closed in the direction
of –.
3.Pressurise your system slowly.
4.Turn the rotary knob in the + direction until the
desired pressure is displayed on the pressure gauge.
The permissible output pressure (pressure regulation
range èTechnical Data chapter ) must not be
exceeded. Correctly pressurised, the operating
pressure p1 is at least 0.5 bar higher than the output
pressure p2.
5.Press the rotary knob down to the housing. The button
will then lock itself against unintentional turning.
If necessary:
 Press the unlocking device 1 (è Fig. 2) outwards. An
existing padlock LRVS-D protects the unlocking device.
Setting the output pressure p2 with control pressure p12
(MS9-LR--PO only)
1.Pressurise your system slowly.
2.Use an external pressure regulator to pressurize the
connection in the cover of the MS9-LR--PO with the
required control pressure p12. Note that the control
pressure must always be higher than the desired output
pressure. The diagram (è Technical data) shows the
difference between control pressure p12 and output
pressure p2.

Replacing the filter cartridge for MS9-LFR/LF
 Replace the filter cartridge if the flow is reduced in spite
of unmodified pressure setting.
1.Exhaust the device.
2.Push the unlocking slide 8 in the direction of the arrow
(è Fig. 7).
3.Turn the filter bowl by hand or by the hexagon as far as
possible in an anti-clockwise direction (as seen from
below] until it is heard to strike the stop.
4.Pull the filter bowl away from the device (è Fig. 8).
5.Turn the filter plate 9 in an anti-clockwise direction
(è Fig. 9).
6.Replace the filter cartridge if the pores are dirty
(è Fig. 10).
Hold the new filter cartridge only at the lower end. The
filter cartridge has a cone shape and must be pushed
into the carrier with the wider end first.
7.Place the new filter cartridge onto the filter plate and
tighten it hand-tight. (è Fig. 11).
8.Fit the individual parts together again in the reverse
sequence. The following checks must then be made:
– the locking pin of the filter bowl must face the large
recess in the housing (è Fig. 12).
– the unlocking slide must be heard to clip into place
when the end stop is reached(è Fig. 13).
9. Commission the system again.
10.Dispose of the used filter cartridge in compliance with
the local waste disposal stipulations.
Cleaning the filter cup aJ for MS9-LWS
The filter cup must be cleaned in regular intervals if there
are impurities in the condensate. The cleaning interval
depends on the level of contamination of the compressed
air used and the tubing system. Cleaning is required when
the sight glass is full of condensate and it doesnt drain
away. The filter cup, however, must be cleaned at least
once a year.
1.Drain the filter bowl if necessary by emptying it manu
ally.
2. Exhaust the device.
3.Loosen the 4 mounting screws aA on the bowl cover
(è Fig. 14).
4.Remove the bowl cover with the filter cup aJ from the
MS9-LWS. Make sure the O-ring aB is not lost.
5.Hold the exterior of the filter cup under running water.
Turn the filter cup when doing this. Use a soft brush to
remove any hard deposits from the filter cup. Do not
use any sharp objects as these can damage the filter.
6.Assemble the bowl cover and O-ring aB to the MS9-LWS
by using the 4 mounting screws aA.
7.Commission the system again.
Cleaning the service unit
If the device is dirty, clean the exterior with a soft cloth.
Permitted cleaning agents are soap suds (max.+60 °C) or
petroleum ether (free of aromatic compounds).
