For each device drain a syphon must be provided. The installation can be
seen in picture 1. The length of the arc (5) and plunger tube (6) has to
be adapted to the existing negative pressure. In case of drains of ¾“ up
to 1 ½“ connecting elements and rubber sleeves are automatically
delivered (parts 1 to 5). The syphon may not be connected directly with
a drain conduction but it must be guaranteed that it can run out freely.
Before putting into operation the device or longer standstill periods the
syphon must be cleaned (cleaning 4 times a year). Also the drop
separators have to be cleaned half - yearly with a steam vacuum
cleaner. If there are several drains in one device then a separate syphon
has to be put on each sleeve. Do not connect on one common
conduction. If the syphons are regulary delivered a functional test must
be made in time to avoid water damages.
