Application for Concentrate

For use in accordance with BS7593:2006. Unless completing an annual top-up, for best results pre-treat the system with System Cleaner prior to adding System Inhibitor.

The concentrate is added to a radiator using the supplied adaptor and a cartridge gun. Close both valves on the radiator and remove the bleed screw using a radiator vent key. Push and turn the adaptor clockwise into the opening to make a tight fit. If necessary, trim the end of the plastic adaptor with a craft knife. Open the cartridge by cutting off the domed end and connect the adaptor. Open one valve of the radiator and using a cartridge gun inject the whole contents of the cartridge into the radiator. Then close the valve again to remove the adaptor and replace the bleed screw. Finally open both of the radiator valves. After using this treatment the radiators should be bled to remove trapped air.
