| Drain the central heating system or plug-off feed and expansion tank and release the system pressure. Measure and mark a 110mm section for a 22mm unit and a 195mm section for a 28mm unit when making the connections with elbows supplied, as shown in 2 below. When installing beneath a boiler or other object, allow 250mm clearance from the top of the canister to beneath the object, to enable the lid assembly to be removed when servicing. This applies to both 22mm and 28mm MagnaClean Professional filters. |
|
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. |
|
IMPORTANT – Ensure the louvres are in the correct position according to the flow. If the flow enters the bottom inlet, both louvre triangles should point to the sheath stem. If the flow enters the top inlet, both louvre triangles should point away from the sheath stem. |

 |
| Loosely secure the MagnaClean Professional to the valves. Grip the MagnaClean canister and tighten the compression fittings being careful not to over tighten. |
|
Loosen off the valve flange nuts and insert the rubber washers provided. Thoroughly tighten the flange nuts. Do not over tighten. Refill the heating system. |
|
Run the central heating system, checking for leaks. Attach the self-adhesive MagnaClean label, as above, to the boiler. Always service the filter before leaving the premises. The lid and valve spanner can be left with the customer.

| Servicing |
 |
|
 |
|
 |
IMPORTANT – Before commencing any servicing work, turn off electrical supply to the boiler. Ensure the water is not too hot to undertake work on the system. Turn off both isolation valves to the marked OFF position. Loosen the air vent to release internal pressure. When venting, protect the surface beneath the MagnaClean Professional with a dust sheet or container to capture any drops of water.
|
|
Using the MagnaClean Professional lid spanner,
carefully unscrew the lid. |
|
Remove the complete lid assembly from the MagnaClean Professional. Turn the lid assembly upside down in order that the underside of the lid acts as a drip tray. |
 |
|
 |
|
 |
| Wrap paper towelling around the build-up of sludge on the plastic sheath. Place lid assembly over a bucket and remove the plastic sheath from the magnet, remove the sludge then rinse clean. |
|
Unlock the base of the sheath and remove the debris collector. Rinse until all non-magnetic debris has been removed. Replace and secure the debris collector onto the sheath and place back into the MagnaClean Professional. Insert the magnet lid assembly and tighten until sealed. |
|
Open the isolation valves to the marked ON position and vent/bleed through the Pro-Fill air vent. Protect the surface beneath the MagnaClean Professional with a dust sheet or container to capture any drops of water. Run the central heating system while checking for leaks. Repeat servicing 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 chemical adapter and feed in chemical. |
|
Wait for five seconds before removing the adapter. 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. |
