Drain the central heating system or plug-off feed and expansion tank and release the system pressure. Measure and mark an appropriate section when making the connections with elbows as shown (Refer to the Installation Instructions inside the box). When installing above a boiler or other object allow 95mm clearance between the magnet cap to the top of the boiler or other object for the removal of the clear base when servicing.
|
|
Using a suitable cutter, carefully remove the marked section of pipework to create the correct opening. |
|
Prepare the pipe and fittings accordingly. Lubricate the olives and assemble the valves on the pipe. Hand tighten. |

 |
|
 |
Loosely secure the MagnaClean TwinTech canister to the valves, following the flow direction indicated on the canister. Tighten the compression fittings, being careful
not to over tighten. |
|
Loosen off the valve flange nuts and insert the rubber washers provided. Tighten the flange nuts. Do not over tighten. Refill the heating system. |
|
Run the central heating system while checking for leaks. Attach the self-adhesive MagnaClean TwinTech label to the boiler, indicating the date of installation, serial number and location of the filter. Always service the filter before leaving the premises. The MagnaClean TwinTech large spanner, valve spanner and servicing tray can be left with the customer.

| Servicing |
 |
|
 |
|
 |
Important - Before commencing any servicing work, turn off the electrical supply to the boiler. Turn both isolation valves to the marked OFF position. Loosen the air vent to release internal pressure. When venting, protect the surface below the canister with the servicing tray provided to capture any drops of water.
|
|
Loosen the canister base with the large spanner while holding the tray beneath. Carefully unscrew the clear base. Allow water to collect in the servicing tray supplied. |
|
Once removed, place the clear base over a bucket. Unscrew and remove the magnet cap and rinse the sheath. |
 |
|
 |
|
 |
| Remove the wire gauze and rinse. Wipe and clean out the clear base. Replace the wire gauze and the magnet cap. |
|
Re-attach the clear base to the top section of MagnaClean TwinTech and tighten until sealed. Do not over tighten. |
|
Open the isolation valves to the marked ON position and vent through the Pro-Fill air vent. When venting, protect the surface below the canister with the servicing tray provided to capture any drops of water. Run the central heating system while checking for leaks. Repeat steps 1 - 6 if required. Ensure the filter is thoroughly clean before leaving the premises.

| Chemical dosing |
 |
|
 |
|
 |
| With a standard radiator key, remove the Pro-Fill air vent. The built-in, one-way valve will prevent water from escaping. Attach the chemical adapter and feed in the chemical. |
|
Wait five seconds before removing the
adaptor. The Pro-Fill air vent will accept all market-leading chemicals in either liquid or concentrate form. |
|
Replace the Pro-Fill air vent. Allow the system to circulate for 30 seconds. Open the Pro-Fill screw two turns and back-flush until clear. |
