R344
Oil and grease must never be used at gas control units. Oil and grease ignite easily and can intensely react with
some gases under pressure. In special cases greases can be used, which are specified for the corresponding
application.
The use of AirCom regulator for oxygen applications is permitted only with signed units.
Special safety instructions for pressure reducers.
If devices are connected with the pressure reducer ensure via separate protection equipment that no dangerous
pressure will be built up in them. The relief valve of the pressure reducer (if available) is not applicable for these
devices as protection means.
When using cylinder pressure reducers the pressure reducer connector must directly mate with the cylinder valve
connection. The use of adaptors is not permitted.
When changing the gas type the pressure reducer must be sufficiently purged with inert gas.
3.2 Regulations and Rules
The national rules and regulations concerning the handling of:
-
compressed gases
-
toxic gases
-
flammable gases
are to be observed.
4 Installation
4.1 Transport and Packing
Please check directly after delivery the pressure reducer for any transport damages and deficiencies
The port openings of the pressure reducer are often closed via hole plugs to prevent contamination with dirty
particles. Remove plugs just before the assembly.
In case of further disassembly close the port openings again before storing or transporting. Temporarily it can be
done using a strip of adhesive tape by sticking it to the opening.
The pressure reducer (e. g. dispatch to customer service) may only be transported in an appropriate, stable packing.
4.2 Preparation
•
Turn hand knob of pressure reducer counter clockwise until the range spring is complete released.
•
Attach pressure reducer - make sure that connections threads are matching.
•
To ensure that the regulator works properly, all lines have to be purged prior to installing the regulator. Deposits
and other foreign objects can damage the valve seat and influence the regulator’s behaviour.
Do not use any lubricants since this would contaminate the pressure reducer and, in the case that oxygen or nitrous
oxide is used, there is danger of combustion.
The regulator has to be installed in the line in such a way that the air flows in the direction of the arrows on the
housing (IN to OUT).
