2. Maintenance
We recommend the cleaning of the
Red Dragon
®
X
de-
livery / skimmer pump at frequent intervals respectively to
check the needle wheel for foreign objects. To check the
impeller / needle wheel ist not necessary to remove the
skimmer from the filter tank.
Unplug the skimmer from the mains. Remove the nozzle
from its seating. Turn the pump into your direction and
optically check the first row of needles for foreign objects
like snails, mussels, activated carbon pellets, filter cot-
ton or food debris. In case of an accumulation of deb-
ris in the pump, the pump must be disassembled. For all
maintenance, a small-medium cross slit screwdriver may
be required.
2.1. Maintenance of the pump
Before any maintenance work, the pump must be un-
plugged from the mains. Delivery/skimmer pumps of
the
Red Dragon
®
X
series are essentially to be classi-
fied as very low maintenance. Normally, the necessary
maintenance work is limited to the control of the impeller/
needle wheel for constipation. Remove possible items
from the needle wheel with a slim, pointed object.
When the pump‘s loosing power / capacity becomes less,
the cause is often pollution. In the case of possible lime
deposits (especially seawater use), the lime must be re-
moved with a very weak acidity, such as vinegar. Avoid
lateral pressure on the wing wheel or rotor. The pump can
be taken apart almost completely for cleaning.
Red Dragon
®
X pumps have a built-in shutdown automa-
tic. Electronics continuously measure the energy inges-
ted. Should electricity consumption increase for whatever
reason, for example with calcification and resulting unwie-
ldy sliding bearings, pump electronics interprets this as a
malfunction and automatically switches off the pump.
We recommend to check the Red Dragon
®
pump already
after three months, to determine the possible maintenance
intervals that, can be depending on precipitation between
2-12 months.
If the impeller group extremely calcified,
solve the plate between engine and rotor. Cover enter
with a small slot screwdriver, !
carefully

1. Commissioning (Start up of the pump)
Please plug the power cable into the desired wall outlet.
Please note, that sub water level pumps must be only
connected to a ground fault circuit interrupter (FI safe-ty
switch). Furthermore we recommend a frame connector
with voltage surge protection, which, in the case of a short
circuit in the mains, prevents a high voltage boost
to the Red Dragon
®
pump. Voltage
100-240V / 45-65Hz
Please always watch for the pump to be operated with
water filled/dipped/submersibled.
Dry running can
cause significant damage!
1.1. Meaning of display and buttons on the controller
Button On/Off
Turn on/off the pump
Increases the performance of the pump
Button -

Button F
Feed Mode of the Pump
By pressing this button you can adjust the feeding timer,
i.e. switch off the pump for 10, 20 or 30 minutes
(F-10,
F-20, F30)
, after this time the pump starts automatically
and jumps to the last set value. By pressing this button 4
times, you leave this function.
Blue LED´s:
In addition to the display, the LED lamps in
the upper part of the controller symbolically display the
set performance.
Display:
Shows the currently set rotations of the pump
(RPM). After restarting, the previously set value will be
retained.
Display ERR:
Pump has been switched off due to over-
load and will be restarted. Immpeller/Needle wheel may
be blocked by foreign objects. Or dry run, please check if
pump is filled with water or pulls air.
