Installation guidelines
Warning
Before installing the device, check that the system is not under
pressure. Wear necessary personal protective equipment and
keep folow the safety rules when working with pressure
equipment.
Before connecting the drain, blow compressed air through the piping in order to thoroughly
clean out any impurities within it.
If the pipe line system is new, leave drain some time to work. Then open the drain and clean
all components (yearly service).
It is recommended to install a ball valve between the device and the system. This is done to
ensure easy maintenance work on the device without the needed to empty the entire
system. In addition to the ball valve it is also recommended to add strainer, and then the
nipple tubing (16) to allow the flow of air upward. For example, the recommended
installation shown below fig.
The drain valve is normally open. This means that when there is no pressure in the system
the valve is open. The valve automatically closes when the pressure rises to at least 10bar.
AOK 50 must be installed so that the bottom side of the casing is a close to level as possible.
Although a maximum divergence
of ±5 °
is allowed.
