The seal of the counter-current installation box separates the wet hydraulic part from the dry electrical installation part of the device. A damaged or aged seal can cause water to penetrate to the electrical components, which represents a safety risk.
The original design of the seal ensures a precise fit on the contact surfaces of the box and reliable separation of both chambers. Replacement is recommended whenever the box is dismantled or at any sign of moisture in the electrical installation part.
Preventive replacement of the seal as part of the annual service inspection of the counter-current unit is a simple and inexpensive safeguard against costly damage caused by moisture on the electronics.
