Installation – combination/sealed systems
Removal of black iron oxide and non-magnetic material and cleanser for combination/sealed systems
Having completed all relevant preliminary electrical safety checks to boiler and pipework confirming safe isolation and earth path, isolate central heating system and drain.
Identify location for installation of MagnaClean filter. Prepare pipework, installing MagnaClean copper elbows and isolation valves supplied. N.B. Refer to MagnaClean installation instructions.
Having completed the installation of the MagnaClean, remove the filter and attach the MagnaCleanse hoses between the RapidFlush Filter and the MagnaCleanse HTV connector attached to the isolation valve on the pipework. N.B. The flow through MagnaCleanse RapidFlush Filter should enter the bottom right and exit top left.
Turn OFF isolation valves on the RapidFlush Filter. Loosen and remove the lid assembly from one of the RapidFlush Filter canisters.
Add a suitable cleanser to the system via the RapidFlush Filter canisters.
Turn ON isolation valves on the RapidFlush Filter. Re-fill and pressurise the central heating system ensuring the radiators are half-full. Check for leaks.
Turn on heating system (all radiators open) for 15 minutes. The radiators should be hot at the bottom, cold at the top.
Turn off any by-pass valves and all the radiators, leaving only one radiator open at a time. With the system running, using ADEY’s VibraClean tool attached to an SDS drill, set to hammer only mode with no rotary action, agitate each radiator for 15-20 seconds.
Continue the VibraClean radiator agitation to dislodge any sludge deposits until the return hose to the RapidFlush Filter runs clear.
Isolate and clean the RapidFlush Filter as required. Using Personal Protective Equipment i.e. gloves and paper towels, wipe off any magnetite into a bucket or waste bag and dispose of correctly. When satisfied, open up the next radiator, turn off the treated radiator and repeat the process until all radiators are clean.
Set the boiler control to OFF. Attach a drain hose to the MagnaCleanse drain valve and secure with a jubilee clip.
Turn OFF the HTV connector isolation valve 2 on the return pipe to the boiler, leaving the HTV isolation valve 1 open.
Check that all radiators and bypasses are turned OFF, leaving the furthest radiator from the boiler open. Turn on the filling loop and allow the mains water to flush through the system. Allow the water to drain out to a convenient point outside until clear. When complete, fill and vent the radiator and allow to circulate for 30 seconds. Always open up the next radiator before turning off the cleansed radiator. Repeat this process on each radiator until system flushing is complete.
Turn off the filling loop and HTV connector isolation valve 1 and drain MagnaCleanse assembly. All the radiators should now be full. Install the MagnaClean filter to system. N.B. Refer to MagnaClean installation instructions.
Add a suitable inhibitor into the canister i.e. use the Pro-Fill bleed valve or remove canister lid assembly and pour into the filter (holds approximately half a litre). Open up the isolation valves and remove any air.
Turn on the system and re-set controls to the customer requirements. Open any by-pass valves previously closed.
Commission the system following the manufacturer’s instructions. Before leaving the property, carry out the last job – SERVICE MAGNACLEAN FILTER ensuring a final check is carried out for leaks.
