ISOLATE RADIATOR
Radiator Inlet (Thermostatic Valve)
- Set the valve to the ‘OFF’ position.
- If no ‘OFF’ position, remove the thermostatic top by unscrewing its retaining collar and fit the dust cover provided with the valve, screwing it fully down.
WARNING - the ‘FROST’ setting may not cut off the flow, particularly in cold weather, so relying on this setting is NOT recommended.
Radiator Inlet (Manual Control Valve)
- Turn off the radiator valve clockwise, noting the number of turns to close the valve.
- Re-opening and fully closing the valve a few times will grind a better seal.
Radiator Outlet (Lockshield Valve)
- Remove the cover and turn off the radiator valve clockwise, noting the number of turns needed to close the valve.
- Re-opening and fully closing the valve a few times will grind a better seal.
ALLOW RADIATOR TO COOL
The radiator must be near room temperature to prevent possible scalding and damage to the Radclamp membranes and to correctly equalise pressure.
ATTACH RADCLAMPS
- Approximately 7.5cm (3") in from each of the radiator valves fix a Radclamp on the bottom of the radiator with guide rods and seals attached.
- Use the "H" packing blocks to set the distance for the seals to cover each outlet (Original design only).
- Tighten the large knob to hold the Radclamp in place. WARNING - Do not over tighten.
- Remove the seals from the guide rods and keep to hand.
RELEASE PRESSURE
- Use a cloth to catch any water forced out when releasing pressure.
- Use the radiator bleed key to release the air vent screw at the top of the radiator.
WARNING – if water continues to come out after a few minutes, the valves have not isolated the radiator. If the radiator cannot be isolated, the whole system must be drained.
- Re-tighten the air vent screw when vented.
WARNING - forgetting to do this releases water when disconnecting the valves.
DISCONNECT VALVES
- Place an absorbent piece of cloth beneath the union and radiator valve to catch drips.
- Slacken off and disconnect the union nut using Radwrench and Radspanner.
- Gently pull the radiator valve away from the radiator creating a gap and slide the seal into it, covering and sealing the radiator outlet.
- Slide the guide rod with retaining cap up to the slot in the seal’s fork.
- Engage cap with the slot and rotate the rod ½ a turn to connect.
- Tighten the small pinch bolt by hand to hold the seal in position.
- Repeat the above for the other valve.

REMOVE RADIATOR
- The radiator can now be lifted from the supports.
WARNING – the radiator is full, so heavier than without the use of radclamps. Get help with lifting or partially drain the radiator to prevent strain.
WARNING – careless handling can dislodge the radclamps. Take care when moving and positioning the radiator.
WARNING – even an empty radiator contains enough sludge to damage flooring. Re-attach the radclamps after draining or cleaning.
REPLACE RADIATOR
- Follow the reverse of the instructions for REMOVE RADIATOR and then DISCONNECT VALVES.
- Remove the Radclamps and follow the reverse of the instructions for ISOLATE RADIATOR.
- Follow the instructions for RELEASE PRESSURE to bleed all the air from the radiator.
