STEP 1: Position the STOPCOR® Device

Install the STOPCOR® unit near the main water supply or directly on the equipment requiring protection, such as commercial boilers, water storage tanks, or main plumbing lines.

STEP 2: Connect the Black Cable (Jubilee Clip Connection)

Locate the black cable on the upper side of the STOPCOR® device, expose the copper wiring inside, and secure it to a clean metal point on the pipe or system using the provided jubilee clip.

STEP 3: Connect the Earthing Cable (Green/Yellow)

Drill a small hole in the wall for the wedge anchor, attach the yellow/green cable to the terminal pin on the STOPCOR® unit, and secure the other end of the cable to the wedge anchor.

STEP 4: Activate the Device

Fill the STOPCOR® unit with tap water using a syringe through the designated hole on the top of the device.

Annual Maintenance

STEP 1: Refill with Water

To maintain optimal function, add water once a year during the routine check:

  • 30ml for STOPCOR® C5
  • 50ml for STOPCOR® C7
  • 100ml for STOPCOR® C9

STEP 2: Test with a Multimeter

Measure the voltage using a multimeter. The reading must be over -1V to ensure the system is working correctly.

STEP 3: Replace After 3 Years

The STOPCOR® unit should be replaced every three years for continued protection.
