Electrical Connection
The system has been designed and constructed according to the applicable regulations. It was carefully inspected before leaving the
factory and left the factory in a perfectly safe condition.
The equipment can only be operated safely if all of the instructions contained in this manual are followed. The equipment should be
installed by a licensed electrician.
The supply voltage for the device may not exceed 240 V / 50 Hz. The allowable operating temperature range is from 0 to 50
°C, and
the allowable humidity level equals 0-90 %.
Ensure that all plug-in connections are protected against water, as is standard practice for electrical connections.
Double Dosing Pump Lock
Pool Relax is equipped with a double pump lock that offers a very high level of safety.
The flow switch in the measurement cell ensures that the dosing pumps can only be switched on if a sufficient amount of water is
flowing through the measurement cell.
In addition, the dosing pumps are supplied with the line voltage through a separate power supply. The power supply must be switched
in such a manner that the dosing pumps are only supplied with current when the circulating pump is running.
In this way, dangerous dosing is prevented even in situations in which there is no flow, i.e. the system is doubly safeguarded.
For connections, please see the "Connections on Controller Housing" chapter.
Earthing the Measurement Cell
The Pool Relax measurement cell is equipped with an earth screw that is used for diverting any potentials on the pool water.
Note
The earthing provided chamber MUST be installed. Make sure that the earthing is functioning properly. Always ensure
that fault current is not flowing into the water of the swimming pool. Professional measurement is recommended.
