Dry-running sensor Hydrostop
Read instructions carefully before operating this device. Keep instructions for future reference.
Safety first!
Electricity and water are a dangerous combination! A current-carrying cable or electrical appliance in water can lead to a lethal electric shock, as soon as somebody touches the water. It is therefore absolutely necessary that you observe the following safety information:
The dry-running sensor’s outer parts (plug, cable and sensor enclosure) must not come in contact with water. Position the dry-running sensor so that
no parts can fall into water;
no water can run over any of the parts when the pump starts;
no parts can become moist by atmospheric influence;
any possibly used extension cables do not come in contact with water either.
Connect the dry-running sensor only to a power source meeting the following requi- rements:
Power supply cables and extension cables with a minimum conductor cross sec- tion of 1.0 mm required by VDE for rubber-sheathed cable type H07 RNF.
When pumping from swimming pool or garden pond, the pump must be protected by a residual current device according to VDE 0100, parts 702 and 738.
Check dry-running sensor for any damage before use. Do not use a damaged device; it cannot be repaired, as the device will no longer be waterproof. Damaged cables in particular must not be repaired. If the dry-running sensor is faulty, replace with an intact one.
Drain dry-running sensor completely if there is risk of freezing.
