Installation of the sensor
Do not remove the adhesive strips yet!
The sensor
e
is fixed to the outer side of the basin (aquarium, filter basin, sump) with an adhe-
sive strip; the water level of this basin must be monitored. The corresponding basin must be
prepared such that the sensor can be fitted properly. The fixing position must be a dry area with
no risk of splashed water. The pump should not be in the water as yet. The adhesive surface on
the outer side of the glass panel must be dry, clean and free from grease. Clean the adhesive
surface using methylated spirit. All-purpose cleaners, bathroom cleaners or similar are not suit-
able for use on the aquarium.
Now, connect the power supply unit to the socket; on doing this, the red LED ( C1) on the
controller gets activated and glows constantly.
Then, place the sensor from outside on the glass panel of the basin above the water level in a
horizontal position (both the LEDs S1 and S2 on the sensor glow) ( 1.).
Slowly move the sensor downwards ( 2.) until the yellow LED ( S2)goes out. Ensure that
the sensor is in contact with the basin glass during this entire movement ( 3.).
On the basin, mark the position of the sensor, on which the yellow LED has gone out ( 4.).
Only after this is done, pull out the protective foil of the adhesive strip ( 5.) and press the
sensor forcefully on the glass in a horizontal position for 10 seconds ( 6.).
Caution: Do not bring the sensor and adhesive strip in contact with water / splas-
hing water! Even very small quantities of water / water droplets between the glass
pane of the basin and the sensor lead to malfunctioning!
Never place the sensor close to metallic objects or cables, these, too, lead to
malfunctions!

Connect the hose
f
to the water outlet of the pump ( P1). Then place the pump
c
in the
water reservoir. Guide the hose
f
to the point on the aquarium at which the aquarium is to be
filled with water and, where necessary, shorten the hose
f
to the required length. Insert the
drain elbow
g
in the other end of the hose
f
and clip the mount ( H2) to the elbow.
The outlet opening of the drain elbow
g
must always be installed above the water level. If the
end of this tube is submerged in water, water from the filter basin or aquarium will flow in the
reservoir or vice-versa, according to the principle of communicating pipes, until the water level
in both the containers is the same.
In order to avoid wave movements in front of the sensor, the mount
h
must be so fixed to the
aquarium glass using the retaining clip ( H1) that the water discharge is at least 5 cm away
from the sensor. In addition, it is recommended, by means of the shut-off valve
d
to restrict
the delivery rate of the pump
c
to the extent that the refilling operation takes at least 15 se-
conds.
