OPERATION AND CYLINDER CHANGE OVER

1. START UP OF MANIFOLD

When the unit is completely installed and all shut o valves are closed.

• Slowly open gas cylinder shut-o valves.

• Slowly open shut-o valves V1, V2 and V3.

• Open purge valve V5.

• Slowly open main-shut-o valve V4 to ventilate the unwanted “air” from the collecting unit and

high pressure hoses and close it back.

• Close purge valve V5. The purge valve V5 must be closed during operation.

• You should keep at least one of the cylinders closed to be used as reserve one. Close shut-o

valve V1, V2 and/or V3 for concerned cylinder(s) and concerned gas cylinder shut-o valve.

• Assign cylinder with indication panels (Fig. 4).

• To check if there is enough gas in the cylinders, use inlet gauge M1.

• Check gauge M2 if the outlet pressure is as required.

2. CYLINDER CHANGE OVER

When 3 gas cylinders are connected to the collecting unit C1 and the one which is in use indicates

low pressure,the following steps are to be taken:

• SLOWLY open full cylinder and its corresponding shut o valve on the collecting unit.

• Close empty cylinder and the corresponding shut-o valve.

• The gas cylinder indication panels must be now adjusted so that it is clearly apparent which

cylinder is in use.

• Exchange the empty cylinder(s) for a full one.

• Close shut-o valves (V1 and/or V2 and/or V3 and/or corresponding to full gas cylinders or cylinders

you do not wish to exchange. The gas ﬂow supply has now been stopped.

• Open shut-o valve V4.

• Close cylinder shut o valve of the empty cylinder(s) that you wish to exchange.

• Open purge valve V5 to evacuate remaining gas from the collecting unit and high pressure hoses.

Close the purge valve V5 when all gas is evacuated.

• Close the opened shut-o valves (V1 and/or V2 and/or V3 and V4).

• Exchange empty cylinder(s) with full one.

• Ventilate the unwanted gas as described in chapter 7.1 from the changed cylinders.

• Then continue using the gas supply from the previously used cylinders. The indication panels

must always match the cylinder(s) in use to prevent unexpected running out of gas.

When 3 gas cylinder are connected to the collecting unit C1 and all 3 are empty, the following

steps are to be taken:

• Open main shut o valve V4 .

• Close cylinder shut o valves.

• Open purge valve V5 to evacuate remaining gas from the collecting unit and high pressure hoses.

Close the purge valve V5 when all gas is evacuated.

• Close the shut o valves V1, V2, V3 and V4.

• Exchange empty cylinders for full ones.

• Now follow steps from chapter 7.1 - start up the manifold.

3. SHUT DOWN

The manifold can be only shut down with agreement of a responsible person according to standard

EN ISO 7396-1.

For short term (hours) shutdown close shut-o valve V4.

For long term (days) shutdown close all opened shut-o valves on the unit (V1 - V4)and the cylinder

shut-o valves

KEEP THE PRODUCT AND ITS ASSOCIATED EQUIPMENT AWAY FROM:

• heat sources (ﬁre, cigarettes, ...)

• ﬂammable materials,

• oil or grease (especially be careful if hand cream is used),

• water,

• dust.

The product and its associated equipment must be prevented from falling.

Always maintain oxygen cleanliness standards,

Use only the product and its associated equipment in a well ventilated area.

It’s very important to assure that the device can be only accessed by a qualiﬁed

person – possibility of misuse.
