ventilation. Make sure that exhaust openings cannot be plugged up and that toxic gases can be exhausted on
fixtures and plants accordingly with venting valves. Some gases can displace oxygen from the air and cause
suffocation. Make sure you have good ventilation when using such gases. It is quite recommendable to install
detectors that emit an alarm in case of a lack of oxygen at the workplace.
Oils and greases must never be used on gas regulating systems. They can ignite easily and react violently with
some pressurised gases. In special cases, lubricants can be used that are suited then for the respective
application.
Implementing AirCom filter pressure regulators in oxygen applications is only permitted with appropriately marked
devices.
Special safety information for filter pressure regulators.
If devices are connected to the filter pressure regulator, it needs to be ensured by special protective precautions that
no dangerous pressure can build up inside. The secondary venting of a filter pressure regulator (if equipped) is not
suitable as protection for these devices.
When changing the type of gas, the filter pressure regulator should be purged sufficiently with inert gas.
For technical gases, use only filter pressure regulators with internal screw plugs and without drains.
3.2 Regulations and guidelines
The following regulations and guidelines must be observed in Germany, depending on the case:
-
Principles of prevention
-
Operation of working materials
-
Guidelines for laboratories
-
Ordinance on Industrial Safety and Health
-
Data sheets "Hazardous substances"
4. Installation
4.1 Transport and packaging
When the filter pressure regulator is delivered, please check it for possible transport damage or defects. The
connection openings of the filter pressure regulator may be closed for transport by caps to prevent dirt particles from
entering. Do not remove the caps until just before installation. In case of a later disassembly, the connection
openings need to be closed again before being put into storage or being transported. This can also be done
provisionally by a strip of adhesive tape that is taped over the opening. The transport of the filter pressure regulator
(e.g. sending to customer service) may be done only in a suitable study package.
4.2 Preparation
Turn the adjusting screw (hand wheel, spindle, hexagon) on the filter pressure regulator counterclockwise until the
range spring is completely relaxed.
The system into which the filter pressure regulator should be installed has to be depressurised.
Connect the filter pressure regulator – connection threads have to match.
To ensure the filter pressure regulator is in perfect working condition, all lines needs to be purged prior to installation.
Deposits and other foreign objects can cause damage to the valve seat, and thus interfere with the regulating
function or make it impossible. No lubricants may be used during installation. The filter pressure regulator may soil
and there is a risk of burning out if oxygen or nitrous oxide is used.
The filter pressure regulator has to be installed in the line in such a way that the gas flows in the direction of the
arrows stamped/taped on the housing (IN to OUT).
The installation position must be observed. The container always has to be at the bottom.
