Level control

General information

The level control consists of: an electronic control unit, a mini liquid level switch and a magnetic valve (optionally item no.
112501).
The level control is built up in modern microprocessor technology. The microprocessor controls the operate lag and the drop-out
delay for the magnetic valve thus not causing a direct switching process with undulations; additionally short switching intervals
are avoided. The liquid level switch is operated with safe extralow voltage. The control unit itself has been produced according
to the prevailing VDE regulations.
Pahlén can provide a cover (optionally, item no. 112503) for protection of the level switch.
For easy mounting of lever control in a skimmer WIDE Pahlén can provide a bracket-kit (optionally, item no. 112504).

Installation
Level control
The swimming pool shall be designed in such a way that a possible technical defect, a failure or a defective control system can
not cause a consequentional damage.
The control unit has to be installed humidity protected, corresponding to its protection type.
The power supply of the device has to be carried out via an all-pole main switch having a contact opening of at least 3mm.
Before opening the housing it is absolutely necessary to switch the device to zero potential.
Any mounting of the stainless steel parts must be worked with cleaned tools designed for
this purpose.
– in skimmer Classic and Marine
Upon delivery the floater has been fixed on the guide so that the switch on point is down.
This is the normal case for water refilling in swimming pools. If the floater is twisted 180°
onto the guide, the switch on point is top and the switching function reversed (see switch
symbols at the floater).
1. Fix the floater on the slide angle bracket.
2. Mont the fixation bar vertical on the skimmer wall in roughly at the required water level.
The fixation bar can be squeezed in between the skimmer plate an the nut from the
cabel gland.
3. Adjust to the desired water level by sliding the angle bracket in the bar.
4. Fix the angle bracket with the grub screw.
