3.14 Installing the level sensor tube
If your pump is not equipped with a float switch, you
must install a level sensor tube in the tank.
1. Fix the level sensor tube to the brackets inside the
tank. The locking ring of the tube must be under
the top bracket to prevent the tube from rising with
the water level.
2. Lead the level sensor hose through the gland.
3. Tighten the gland.

3.15 Installing an alarm float switch
If you have an alarm device, you can install an
additional float switch inside the tank and connect it to
the alarm device in order to trigger a high-level alarm.
If you have an LC 220 or LC 221 controller, you do
not need an additional alarm float switch as high-level
alarm is triggered by the level sensor.
1. Fix the cable of the float switch to the pump
connecting pipe with a cable tie.
• Make sure that there is a free cable length of
minimum 70 mm.
• Make sure that the float switch can move freely
from its lowest position to its highest position.
2. Tighten the cable tie.
3. Drill a hole,
∅
20, for the cable gland.
4. Fit the cable gland. See fig. Fitting the cable
glands.
5. Lead the cable of the float switch through the
cable gland.
6. Tighten the cable gland.
