You can do so by installing a gravel layer at the bottom of the shaft. An optional immersion pump
with a float switch that is connected to a canal or drain additionally protects your filter system from
rising water inside the shaft.
- Ensure sufficient natural ventilation of the shaft to prevent condensation.
- Design the size of the filter shaft so that you can carry out work on the filter system.
Description of the filter system
The filter balls in the filter vessel
passes through the suction line
the top into the filter vessel.
When the water flows through the filter balls, dirt particles are deposited and filtered out of the water.
The cleaned water flows through the filter cover in the return line
If the manometer
on the filter cover rises above 1 bar, the filter balls are very dirty and must be

cleaned.
Function principle of the timer
With the integrated timer, you can start and stop the pump automatically once a day for the set time. To
set several intervals within a 24-hour period, you need an external timer.
The timer has a battery (see section "Technical data"). The start time and the running time are saved in
case the power supply is interrupted or fails altogether.
Filtering time
The pool's water content should be circulated at least twice in a 24 h period. In case of heavier
frequency, the pool water should be circulated 3 to 5 times per day.
Before First Use
Risk of death when operating the water treatment system during bathing.
Hair or clothing might get sucked into the suction openings of the pool and in extreme cases
trap persons under water and prevent them from surfacing again.
- Never operate water treatment system devices while persons are in the pool.
- Prevent any access to the pool for as long as water treatment system devices are in use.
Clarifying agents in the pool water can lead to clumping of the Active Balls and severely
impair their cleaning effect.
- Do not use any clarifying agents for water treatment when using Active Balls as filter
medium.
Check the following before start-up
- The device is out of the pool and the power cable is disconnected from the mains
Initial start-up of the timer
The timer is going to function flawlessly even if you do not perform the steps described below. However,
should the power supply be interrupted, the saved filter running times will be lost.
1. Make sure that the pump's power cable is disconnected from the power supply.
2. With a Phillips screwdriver PH1 , remove the screws of the timer cover and take the cover off.
3. Pull out the strip of plastic from underneath the battery.
4. Screw the cover back on.
The timer's memory backup function is activated.
