Installation
Note: the skimmer is not frost prove.
a) Place the Fresh Skim beside the biological filtration unit on even and level ground to
guarantee the stability of the system.
b) Make sure there is no tension or weight on the piping.
c) Connect the water pump (delivery ca. 22 m3/h) to the water inlet of the skimmer. We
recommend using a flow meter (2500 - 25000 l/h). Please do not install an extra filter
as it changes the water passage and so might cause deviations of the water level. In
this case the skimming process gets unstable.
d) The water outflow operates pressureless, the ventilation pipe mounted to the water
outlet prevents the skimmer from heaving empty.
e) Connect the air pump (delivery ca. 5 - 10 m3/h) with a flexible tube to the air inlet of
the skimmer. Again, we recommend the use of an air flow meter (ca. 2000 - 15000 l/h).
f) The foam beaker can take up a great amount of foam; for a continuous outflow
connect the foam with a drain. To prevent residual ozone from escaping a siphon has
to be installed.
g) The use of ozone increases the foam production.
When using an ozonizer connect it with the “bypass” of the air leading tube. The ozone
leading pipe coming from the ozonizer has to be connected with the upper connection
of the “bypass”.
An amount of 10mg ozone/200l fresh water is recommended. Connect the ozonizer
with the upper inlet of the bypass system.
If the system is operated without the use of an ozonizer, the connection has to be
closed.
h) For the extinction of residual ozone elements a rest ozone decomposer should be
installed. Attach the decomposer with a flexible tube (Teflon or PVC) to the lid of the
foam beaker.
i)
Please follow these instructions carefully. The producer cannot be held responsible for
any water damage.
