Installation

MagnaClean Micro has been developed to deliver effective central heating system protection against the damaging effects of black iron oxide. It is designed to remove magnetic and non-magnetic debris and is suitable for all domestic central heating systems especially where space may be limited.

The filter can be fitted anywhere on the main circuit. However, in order to achieve the best protection for the boiler, it is recommended that MagnaClean Micro is fitted after the last radiator and before the boiler. In determining a suitable location, it is important to allow adequate access for servicing.

The following instructions are designed to assist engineers in the safe and effective installation and servicing of MagnaClean Micro and should be followed at all times. ADEY recommends using the powder-free vinyl gloves provided. Any queries should be directed to your supervisor or ADEY direct on 01242 546700.

In both diagrams, position A is best practice while B is suitable.

N.B. We firmly recommend MagnaClean Micro is installed and
serviced by a qualified heating engineer.

Drain the central heating system or plug-off feed and expansion tank and release the system pressure. Measure and mark a 90mm section when making the connections with elbows supplied, as shown in step 3 below. When installing below a boiler or other object, allow 170mm clearance from the top of the canister to beneath the object, to enable the lid assembly to be removed when servicing.		Using a suitable cutter, carefully remove the marked section of pipe work 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 Micro canister to the valves, following the flow direction indicated on the canister. Grip the 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 while checking for leaks. Attach the completed self-adhesive MagnaClean label 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 below the canister with a dust sheet or container to capture any drops of water.		Using the MagnaClean Micro lid spanner, carefully unscrew the lid.		Remove the complete lid assembly from the MagnaClean Micro. 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 bayonet screw on the base of the sheath and remove the debris collector. Rinse until all the non magnetic debris has been removed. Replace and lock the bayonet screw onto the sheath and place the sheath into the canister. 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 below the canister with a dust sheet or container 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 chemical adaptor and feed in chemical.		Wait for 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.
