6. INSTALLATION
It is necessary that an installer of the product is trained and has an appropriate licence
according to national standards. It is outside the scope of these operating instructions to give
detailed guidance on installations.
The installation must conform to the standard MEDICAL GAS PIPELINE SYSTEMS EN ISO
7396-1 as amended. All tests according this standard have to be fulfi lled.
When working with medical gases it is essential that no oil or grease come into contact with
the gas. This means that hands, tools and work clothes be free from oil or grease before
any work is undertaken. Components used for service must be gas compatible. For oxygen
service must also be degreased and although they will reach you in this condition care must
be taken during storage and handling.
6.1.WALL FIXING
Please consult the positioning of the Pressure Watch with gas supplier and designer. Mount the
Pressure Watch at the height to suit either cylinders or cylinder bundles.
Be aware that only upper screw hold the entire weight of the product. Size of used screws
shall conform to total load.
6.1.1.PRESSURE WATCH COMPONENTS

there are absolutely no traces of copper splint. Soldering should be done with nitrogen as
the protecting gas inside the tube line according to the EN ISO 7396-1
3. Connect the copper tubes and solder them together.
4. Chill the tubes at soldering.
6.1.5.FINAL MOUNTING

7. OPERATION
7.1.START UP OF THE PRESSURE WATCH
When the Pressure Watch is completely installed.
• Make sure that the incoming gas is right for their respective connections.
• Open the input valves slowly.
• Check the outlet gauges D, if the gas pressure is correct for each gas.
• Check all connections for leakage using a 0.5% teepol / water solution.
7.2.START UP OF THE PRESSURE WATCH WITH EMERGENCY SOURCE
When the Pressure Watch with Emergency Source is completely installed.
• Make sure that the incoming gas is right for their respective connections.
• Ensure the valves B on the main gas line are closed
• Before opening the valves L on the Emergency Source gas line check the gauges D on the
Emergency Source gas line, if the gas pressure is correct for each gas.
• Open the valves L on the Emergency Source slowly.
• Check the gauges D, if the gas pressure is correct for each gas.
• Check all connections for leakage using a 0.5% teepol / water solution.
• Close the valves L on the Emergency Source.
• Before opening the valves C on the main gas line check the gauges B on the main gas line, if
the gas pressure is correct for each gas.

7.3.CONTROL THE FUNCTION OF THE PRESSURE SENSORS
1. HIGH PRESSURE OXYGEN.
Close valve C for Oxygen, connect a Oxygen gas cylinder to the female QC for emergency
supply. Increase the pressure to present high pressure level, the alarm gives an signal of high
pressure.
2. LOW PRESSURE OXYGEN.
Remove the gas cylinder and use a male probe (quick connection) to decrease the pressure,
to the preset low pressure level and wait for the alarm.
3. OPEN THE VALVE AGAIN SLOWLY.
Check the alarm levels for all gases in the same way.
7.4.PHYSICAL ISOLATION
Each Pressure Watch or Pressure Watch ES (except for vacuum system) is equipped with a
physical isolation. These device shall be fi tted to each pipe line when modifi cations are needed
to existing system. It shall be fi tted manually to pipe line by trained person.
7.4.1.FITTING PROCEDURE OF PHYSICAL ISOLATION
1. Disassemble the front plate and the inner cover
2. Close the shut off valve on adequate pipe line and ensure the gas is no more fl owing through
3. Disassemble both switches and unscrew the cap nut from the valve
4. Put the physical isolation between the valve and the connection

5. Screw back and tighten the cap nut on the valve
6. Slowly open the shut off valve and check if the gas is fl owing through
7. If yes, please check the assembly of the physical isolation again
8. If the gas is no more fl owing through the physical isolation is fi tted correctly
9. Close the shut off valve
When modifi cations are ready then the physical isolation has to be disassembled from the
pipe line!
7.4.2.DISASSEMBLY OF THE PHYSICAL ISOLATION
1. Ensure the shut off valve is closed
2. Unscrew the cap nut from the valve
3. Take out the physical isolation
4. Screw back and tighten the cap nut on the valve
5. Screw back and tighten the switches – low pressure switch to LP side and high
pressure on the HP side (see the LP and HP marking on the brass block)
6. Slowly open the shut off valve and check if the pressure gauge indicates any pressure
7. If yes, check the external leakage of the connections
7.5.ALTERNATIVE OF PRESSURE SENSORS
ALTERNATIVE 1. PRESSURE SWITCHES:
To set the pressure switches ”PS” (repeat for every PS):
1. Connect an Ohm-meter to the two pins of PS.
2. Rise and sink the pressure by using the quick coupling (and if necessary a spare cylinder).
3. Note at what pressure the PS change from closed to open (seen on the Ohm-meter,
closed=short circuit, open=no contact between the pins). Closed PS = No alarm. Open PS=
Alarm
4. If needed; adjust the PS by operating the screw positioned between the two pins. Turning
the screw clockwise sets the alarm point corresponding to a higher pressure.
5. Reiterate point 2 to 4 until you are pleased with the settings.
6. Connect the PS to Gas alarm according to enclosed Gas alarm instruction.
ALTERNATIVE 2. PRESSURE TRANSMITTER 420 mA:
4 mA is equivalent to 0 bar and 20 mA to the maximum pressure of the pressure transmitter.
The pressure transmitter is linear and you connect it directly to central computer system or local
alarm system. See also IFU for the master system.
