1. Isolate the radiator by turning off the inlet and outlet valves at the base of the radiator.

2. Remove the radiator vent/bleed pin.

3. Now screw the connector into the position where the vent pin was removed. DO NOT OVER-TIGHTEN.

4. Now screw the body of the valve onto the connector. Ensure the body of the valve is vertical when tight, vary the number of washers to suit.

5. When the valve is in the correct position, slowly open the inlet and outlet valve to the radiator. Check that all the seals are watertight.

You can expect many years of trouble-free service once properly installed.
