INTRODUCTION
Today, high eciency boilers oer excellent performance for
heating systems, however this performance can be eroded
signicantly if little attention is given to the cleanliness of the
complete central heating system. Historically the majority of
systems suer from iron oxide contamination, which takes the
form of sludge deposits which are caused by corrosion of the
heating system.
The iron oxide particles vary in size and the sub-micron particles
are present in the system uid continuously during system
operation. The oxide particles can cause premature failure of
valves and pumps and boiler eciency is reduced dramatically as
the particles contaminate the boilers heat exchanger, and the
complete system pipework.
The SALUS Mag Defender oers system protection and increased
eciency, as it has been designed to remove the suspended iron
oxide particles without reducing ow rate through the system.
Installation is simple; isolation valves rotate 360º so a number of
location options can be facilitated.
An added advantage to installers is the bottom mounted valve for
servicing. Once isolated the bottom valve allows the easy
discharge of contaminants. The main body is 500mL, which allows
the installer to add the correct amount of corrosion inhibitor when
the isolation valves are closed.

INSTALLATION
In order to achieve the best protection for the boiler, it is
recommended that the Mag Defender is tted after the last
radiator before the boiler.

INSTALLATION
In determining a suitable location for installation, it is important
to ensure you allow adequate access for servicing.
The following instructions are designed to assist engineers
in the safe and eective installation and servicing of the
SALUS Mag Defender and should be followed at all times.
Any queries arising from either installation or servicing, contact
SALUS Controls direct on 01226 323961.
Do’s:
• Install the ller upright to enable the device to be fully
evacuated of air during commissioning. Pipe runs are vertical,
horizontal or any angle in between. The inlet and outlet can
also be swapped to suit.
• Where the device is tted to the metallic building structure
earth-bonding continuity is required around the device.
All bonding connections must be accessible and labelled
“Safety Electrical Connection - Do Not Remove”
Dont’s:
• Magnets may aect or interfere with sensitive mechanical and
electronic instruments such as heart pacemakers, computers/
magnetic media and watches. Always keep magnets at least
300mm (1ft) away from such equipment.
• NEVER close the INLET or OUTLET isolation valves, or UNDO the
lid when the pump is running!
• Don’t t the device too close to the boiler, allow at least 1m.

MD22 INSTRUCTION MANUAL 5
Release system pressure then drain the pipe run where the device
is to be located (it may be necessary to drain the whole system).
When installing below 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.
The device has been designed to facilitate various inlet and outlet
congurations. Most congurations will require Elbows. For
soldering we recommend 28x Yorkshire Solder Ring Elbow
YP1222mm (code08290), or for compression we recommend
2 Yorkshire copper KS61522mm (code 61124K) and the tting
instructions (which follow) are based around dimensions of these
elbows. For clarity the recommended solder and compression
ttings require the same dimension of cutout.
Vertical pipe run: Measure and mark a 110mm section for a
22mm unit, as shown below. Remove this marked section using a
pipe cutter as shown. Now create 64mm and 106mm of 22mm
copper pipe to attach between the respective elbow and
compression tting on the inlet/outlet. Tip: Reuse the cut out
section.
Horizontal pipe runs: Measure and mark 73mm section and
remove the marked section with a rotary tube cutter. Create
64mm and 134mm lengths of 22mm copper pip to attach
between the respective elbow and compression tting on the
inlet/outlet. Tip: Reuse the cut out section.
Prepare the pipe and ttings, lubricate the olives and connect
the valves on the pipe work, please only hand tighten the
connections at rst.

Now Loosen o the valve ange
nuts and insert the rubber washers
provided. (There are 2 supplied
with this product).
Loosely secure the Mag Defender
to the valves. Grip the Mag
Defender and tighten the
compression ttings being careful
not to over tighten as this may
cause damage.

Now the heating system is ready to
be lled, ensure the inlet and
outlet valves are both in the open
position, with the drain valve in the
closed position, and then run the
central heating system.
Have a bucket ready to collect
spillage and partially open the
drain valve (using the cap as a tool)
to purge air from the device. Close
the drain valve once water starts to
ow. Bleed the device again after
the system has reached
temperature. Take care as the
water will be hot. Replace drain
cap.
Always service the lter before
leaving the premises. The Mag
Defender spanner can be left
with the customer.

Important – Before carrying out
any servicing work, turn o
electrical supply to the boiler and
let the water cool down to a safe
working temperature. Using the
Mag Defender spanner provided
turn both isolation valves to the
OFF position.
Using the Mag Defender spanner
provided, carefully unscrew the lid.

After step 9 in servicing, pour a
bottle of water treatment
corrosion and scale inhibitor, we
suggest SALUS SYSTEM GUARD
Inhibitor. The canister will hold
500ml and the inhibitor should be
poured down the outer edge of
the snorkel.
DO NOT POUR DOWN CENTRE
OF THE SNORKEL
Tip: Cover the centre hole of
the snorkel temporarily with the
inhibitor lid.
Continue with step 10 of servicing.
Once you reach step 13 allow the
system to circulate for 5 minutes
before moving on to step 14.

How long will the Mag Defender last?
Mag Defender has been developed to last for the lifetime
of the boiler, normally ten years. It provides continuous
protection and comes with a ve year warranty.
How do I isolate the valves?
Simply turn the valves to the marked OFF position using
the spanner provided. Important: Remember to switch o
the electrical supply to the boiler when servicing the
Mag Defender.
Will the Mag Defender aect my pacemaker?
As with all magnetic products, if you have a pacemaker
caution should be taken when handling the
