7.3 Leakage Test (Test for External Leakage)
The devices are subjected to a strength and leakage test ex works at MEDENUS Gas-Druckregeltechnik GmbH.
The leakage test in the fully assembled system must be performed prior to commissioning and following maintenance
work.
For the external leakage test in the fully assembled system, the following applies
For Germany:
According to the DVGW work sheet G 491, the fully assembled system must be subjected to a leakage test with air or an
inert gas at the installation site, using 1.1 times the maximum operating pressure of the system (MOP).
An exception is the room between the actuator of the gas pressure regulator installed in the system and the first shut-
off valve on the outlet side. This room must be checked using a test pressure corresponding to the maximum possible
setpoint of the gas pressure regulator. In this test, all detachable connections must be checked using a foaming agent.
For other countries:
The relevant national and international standards shall apply.
Procedure
• Close the ball valve upstream of the valves and fittings.
• Close the downstream shut-off devices (ball valves, solenoid or pneumatic valve).
• Depressurize the system.
• Connect the testing device to measuring points upstream and downstream of the filter.
• Always increase the test pressure slowly and steadily.
While doing so, you must ensure:
Pressure in outlet chamber ≤pressure in inlet chamber
Pressure build-up always from the inlet side (inlet chamber)
Pressure reduction always from the outlet side (outlet chamber)
7.4 Initial Commissioning / Recommissioning
For commissioning, please refer to the relevant manufacturer's documentation of the gas pressure regulator installed
in the system and the work instructions of the system operator.
7.5 Decommissioning

8 Maintenance
8.1 Maintenance Plan
The following sections describe the maintenance work required for optimal and
trouble-free operation of the device. If increased wear is detected during regular inspections, the required
maintenance intervals must be shortened in accordance with the actual wear.
For any questions on maintenance work and intervals, please contact the manufacturer.
The intervals for monitoring and maintenance work are strongly dependent on the
operating situation and the condition of the gas. This is why no fixed intervals
can be given. For Germany, it is recommended that the maintenance periods as specified in the DVGW work sheet G 495
are observed initially.
For each system, this must be followed by determining the maintenance interval independently on a medium-term basis.
During maintenance work, the components must be cleaned and subjected to a thorough visual inspection. This is also
necessary if irregularities in the operating behavior have been detected during operation or during functional tests.
The check must cover in particular the filter insert and the seals.
Damaged parts and O-rings dismounted during dismantling must be replaced with new ones.
The item numbers mentioned in chapter 6.2 (Maintenance Procedure) correspond to those listed in the spare parts
drawings and spare parts lists.
It is recommended to stock the parts listed in chapter 9.5 on page 18 for maintenance work.

15 © 05.2022
8.2 Maintenance Procedure
As a functional test, a pressure loss measurement for the flow resistance can be carried out. Limit
value for a contaminated filter cartridge: Δpmax= 0.8 to 1 bar
• Close fittings upstream and downstream of the filter. Depressurize the filter.
• Dismount the hood. To do so, unscrew the Allen screws on the hood. Exception for DN 25: Unscrew the hood.
• Remove the O-ring (item 8) inside the housing or hood. Clean the O-ring groove and insert a new greased
O-ring into the groove.
• Pull out the filter cartridge towards the top and check whether it is dirty. If necessary, the filter cartridge must
be cleaned or replaced.
• For DN 150 / DN 200: Dismount the spacer. To do so, unscrew the Allen screws (item 55) at the spacer. Remove
the O-ring (item 8) from the housing or from the spacer.
To lower the dismounting dimension for the nominal widths of DN 150 and DN 200, the filter cartridge
and the spacer should be removed together.
• Clean the O-ring grooves and insert new, greased O-rings into the grooves.
• Dismount the cover. To do so, unscrew the Allen screws (item 52) from the cover. It may be necessary to clean
the cover.
• Remove the O-ring (item 4) from the housing. Clean the O-ring groove and insert a new greased O-ring into
the groove.
• Remount the cover. To do so, screw down the Allen screws (item 52) at the cover crosswise, using a torque
wrench. (see Table 6.3)
• Place the cleaned or new filter cartridge in the valve seat. The filter cartridges DN 25 and DN 100 comprise a
centering ring at one end guaranteeing the correct fit of the cartridge in the valve seat. During installation, the
centering ring is located at the bottom inside the filter.
• For DN 150 / DN 200: Mount the spacer. To do so, screw down the Allen screws (item 55) at the spacer crosswise,
using a torque wrench. (see Table 6.3)
To lower the mounting dimension for the nominal widths of DN 150 and DN 200, the filter cartridge
and the spacer should be inserted together.
• Place the hood and tighten the Allen screws (item 50) crosswise, using a torque wrench. Exception for DN 25:
Screw in the hood (item 50) and tighten it, using a torque wrench. (see table 6.3) When screwing in, exert a
slight pressure on the hood. The filter cartridge is oversized and, due to the leak tightness to be achieved, it
must be slightly compressed.
• The maintenance parts in the differential pressure measuring instrument are only replaced when necessary.
• Open the valves and fittings upstream and downstream of the filter and check for leak tightness (using a
foaming agent).
To guarantee smooth operation, we recommend always keeping a maintenance set in reserve.

12.1 Differential pressure gauge
12.1.2 Application / Function
The appropriate national safety regulations (e.g. EN 837-2 "Selection and installation recommendations for pressure
gauges") must be observed when installing, commissioning and operating these devices.
In the HIGH and LOW media chambers, pressures p1 and p2 are present, separated by the magnetic piston under
pressure. The difference in pressure causes an axial movement (deflection) of the piston supported by the measuring
range spring. The deflection resulting from this is taken up by a magnet located on the instrument pointer and
appropriately displayed.
This design combines the advantages of complete separation of the measuring system and the indication while
eliminating any leakage to the exterior. Due to the constructive design, the volumetric flow from the HIGH to the LOW
side of the media chamber is very low and is therefore not an issue.
12.1.1 Use
The differential pressure gauge DP 900 has been designed to monitor differential
pressures on the cellular gas filter DF100.
