1.3. Installation and connection of the external skimmer
The
external
Bubble King
®
DeLuxe skimmer functions
exactly like the
internal
one. Unless otherwise stated, all
instructions listed in the handbook for
internal
skimmers
also apply for
external
skimmers.
However, there is great difference in terms of the connec-
tion because the
external
Bubble King
®
DeLuxe skimmer
requires a delivery pump which supplies the skimmer and
the skimmer pump with the water to be filtered. Please re
-
fer to the data specification of your
external
skimmer for
information regarding the power of the delivery pump.
It is also important to note that the
external
skimmer should
be positioned no lower or higher than the filter unit or water
level.
(See left sketch below)
Note:
If possible,
the water sucked
in by the delivery
pump
should be roughly filtered
ahead to avoid
unnecessarily polluting or contaminating the delivery
and skimmer pumps with snail shells or pieces of coral
for example, which could wear the pin wheel or impeller
and/or lead to a defect.

Important:
Do not posi-
tion the levelling pipe

of the

skimmer either
above or below the wa-
ter level of the filter unit!
There is a high risk that
the filter unit will idle.

Note:
If the geometrical
levelling tube sets back
a long horizontal sec-
tion, an angle should be
used, to ensure a safe
process.
