The HV30C valves comes with easy instruction of how to fit to your radiator, but this post will give you and idea of what is involved. Inside the dust cap (the black plastic bit on the back of the valve) you will find a U key which you will need during the installation, please make sure that you keep hold of this for if you need at some point to replace the cartridge you will need this.
Always try to fit the valve to the hotter, flow side of the radiator as you HV30C will start to work much more quickly.
You will need an adjustable wrench to fit. We also recommend an old cloth to dry the radiator tapping.
- Switch the central heating system off and allow to cool.
- Isolate the radiator. Avoid flooding by closing the radiator valves at the bottom of the radiator – at one end this will be a lockshield valve with a plastic cover – remove the cover and turn the spindle clockwise using the adjustable wrench.
At the other end will either be a wheelhead valve, which can be turned off by hand, or a thermostatic radiator valve which should be turned to 0’.
- Remove the old manual vent. Unscrew the old manual vent plug using an adjustable wrench. Mop up any spillage with a cloth.
- Fit the valve. Screw the valve into the radiator tapping, nip tight with the adjustable wrench. Ensure that the cartridge in the middle of the valve is screwed all the way in (use the ‘U’ shaped insert tool across two of the vent holes).
- Turn the valves back on.
It really is that easy, but if you have any questions or concerns then please do not hesitate to contact us and we will be only too happy to help.
