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.

local standards and it is deﬁ ned by pressure watch conﬁ guration.

1. The valve need not to be demounted at soldering.

2. Cut the tubes in a perpendicular fashion to suitable length. Grade the tubes, and make sure

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.

• Open the valves C on the main gas line slowly.

• Check the gauges D, 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 420 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.

aﬀ ect the continuing safe operation of the manifold.

GENERAL MAINTENANCE SHOULD BE UNDERTAKEN IN ACCORDANCE WITH A PLANNED

MAINTENANCE SCHEDULE, WHICH SHOULD INCLUDE THE FOLLOWING ITEMS:

• Leak test all joints using a 0.5% teepol in water solution.

• Examine mounting frames and cylinder securing chains for damage deterioration and security

of attachment. programme.

• Valves to be used in normal or emergency operation are accessible and easy to operate.

Valves at service point’s outlets and purge valves should be checked for gas tightness.
