ISOLATE RADIATOR

Radiator Inlet (Thermostatic Valve)

1. Set the valve to the ‘OFF’ position.
2. 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)

1. Turn off the radiator valve clockwise, noting the number of turns to close the valve.
2. Re-opening and fully closing the valve a few times will grind a better seal.

Radiator Outlet (Lockshield Valve)

1. Remove the cover and turn off the radiator valve clockwise, noting the number of turns needed to close the valve.
2. 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

1. 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.
2. Use the "H" packing blocks to set the distance for the seals to cover each outlet (Original design only).
3. Tighten the large knob to hold the Radclamp in place. WARNING - Do not over tighten.
4. Remove the seals from the guide rods and keep to hand.

RELEASE PRESSURE

1. Use a cloth to catch any water forced out when releasing pressure.
2. 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.

1. Re-tighten the air vent screw when vented.

WARNING - forgetting to do this releases water when disconnecting the valves.

DISCONNECT VALVES

1. Place an absorbent piece of cloth beneath the union and radiator valve to catch drips.
2. Slacken off and disconnect the union nut using Radwrench and Radspanner.
3. Gently pull the radiator valve away from the radiator creating a gap and slide the seal into it, covering and sealing the radiator outlet.
4. Slide the guide rod with retaining cap up to the slot in the seal’s fork.
5. Engage cap with the slot and rotate the rod ½ a turn to connect.
6. Tighten the small pinch bolt by hand to hold the seal in position.
7. Repeat the above for the other valve.
8. Gently pull the radiator valve away from the radiator creating a gap and slide the seal into it, covering and sealing the radiator outlet.
9. Slide the guide rod with retaining cap up to the slot in the seal’s fork.
10. Engage cap with the slot and rotate the rod ½ a turn to connect.
11. Tighten the small pinch bolt by hand to hold the seal in position.
12. Repeat the above for the other valve.

REMOVE RADIATOR

1. 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

1. Follow the reverse of the instructions for REMOVE RADIATOR and then DISCONNECT VALVES.
2. Remove the Radclamps and follow the reverse of the instructions for ISOLATE RADIATOR.
3. Follow the instructions for RELEASE PRESSURE to bleed all the air from the radiator.
