/ MONARCH MAGNESIO WATER CONDITIONER PROGRAMMING &
INSTALLATION INSTRUCTIONS
Thank you for choosing our water conditioner. Please read the following
carefully, which if followed correctly, should ensure the installation is trouble
free.
/ A. PLANNING THE INSTALLATION
• Always observe the water byelaws.
• Ensure there is only one rising main.
• Make sure you have allowed space for access to the unit for magnesium flake filling and for any
possible maintenance in the future.
• Check the water pressure and locate the rising main, a drain facility and a power supply. Be aware
of condensation occurring in warm environments.
/ B. SITING THE CONDITIONER - Fig 1 (Page 6)
• Where possible, this should be close to the rising main.
• Tee off for mains water supply to outside tap if applicable.
• The distance between the Magnesio and the drain should be as short as possible, to ensure that
both the drain and the overflow are not subject to freezing, or over 120°F/49°C.
• If siting the conditioner within a cupboard, loft etc. ensure that the base/floor is adequately
supported.
/ C. CHECK VALVE
• Conditioned water for drinking or food preparation is category 2 which requires a single check
valve type EA or EB.
/ D. MATERIALS
Ensure all installation components comply with appropriate water regulations.

/ G. WATER PRESSURE TEST
• It is IMPORTANT that a pressure check is carried out.
• Low and high pressure can result in either damage to, or failure of the unit.
• If daytime static water pressure* exceeds 3.5 bar (50psi) a 5 bar (70psi) pressure limiter should be
fitted. *50psi daytime pressure can reach nearly 100psi at night!
• Minimum dynamic pressure must exceed 1.5 bar.
• If in any doubt please call us on [phone]
/ Check List
• Water pressure 1.5 – 5 bar (20 – 70psi)
• Access to incoming water supply
• Access to 3 pin socket
FIG 1
• Access to drain
• Installation preferably on an outside wall for the
overflow
• Easy access to fill unit with magnesium flakes

FIG 2
DRAIN CONNECTION
/ I. DRAIN CONNECTION
• 2.5mtrs of white low pressure drain hose is supplied with the unit. This is to be used for both the
drain and overflow. The drain connection is the black barbed elbow under the rear top cover. To
remove rear top cover, simply slide forward out of fixing, and lift off. Fix drain hose to black barbed
elbow with jubilee clip (supplied).
• Run the drain hose to either an upstand or an outside drain. Connect the drain hose to the spigot
of the Air Gap provided to ensure a 20mm air gap exists at the end of the drain line.
• If you need to extend the drain hose, this can be done by connecting to a 15mm copper tube for
a maximum run of 4 metres, with a minimum daytime pressure of 40 psi. Over 4 metres please use
22mm (or similar) copper tube.
• Ensure that the drain hose is adequately fixed to the copper pipe.
• The drain hose must not dip or be kinked in any way, as this will lead to an overflow of the
machine.
• UPHILL? The white flexible drain hose can run uphill internally, for a maximum of 3 feet, with a
minimum water pressure of 40 psi.
• Under no circumstances should the drain and overflow share the same pipe. This could lead to foul
smells entering the cabinet from the main drain via the overflow. Also, if the common drain ever
gets blocked, the water can re-enter the conditioner via the overflow pipe.
/ J. OVERFLOW CONNECTION - IMPORTANT (White elbow connection on back of cabinet)
• The hose for the overflow should be cut from the white low pressure hose supplied with the unit.
• The overflow connection is the ½” hose spigot on the rear right hand corner of the cabinet – no
jubilee clip required.
• The overflow must be run downhill and terminate immediately through an outside wall without kinks
or restriction.
• A 22mm (or similar) copper protective sleeve through the outside wall will help prevent kinking of
the hose.
/ K. TEST INSTALLATION FOR LEAKS
Place the bypass handles in the horizontal Bypass position. Open mains stopcock slowly to flush the
new pipe work. This can be done using a mains tap i.e. utility room cold tap or wash hand basin in a
bathroom. Check all connections for leaks.
/ H. INLET & OUTLET CONNECTIONS - See Fig 2
• Remove the main cover to access the inlet and outlet
connections.
• Remove grey retaining clips and also BSP connection points.
Connect hoses to male BSP connection points, tighten to seal, then
reinsert BSP connection points back into valve body. Fit grey clips.
The connection points are designed to rotate once inserted in valve
body. This removes any stress/ pressure.
• We recommend you fit the elbow end of the hose to the inlet/
outlet connection points on the Magnesio.
Under no circumstances use washing machines hoses or plumb the
conditioner in solid copper pipe.

/ L. ELECTRICAL CONNECTION
With the power off, connect the transformer (supplied) to a continuous electrical supply. Push the
flying lead from the transformer into the adaptor on the lead coming from the controller.
/ M. OBTAIN YOUR WATER HARDNESS
• These instructions apply to the enclosed test kit only.
• Run hard water for approx. 1 minute and rinse the test tube well.
• Fill the test tube up to the 10ml level. Add 2 drops of the dark solution and mix gently. If the
water sample contains hardness it will turn red.
• Add the dark solution in batches of 5 drops, holding the dropper bottle at 45 degrees.
• Mix gently after each 5 drops.
• Count the drops needed until the colour of the sample in the test tube changes from a dark red to
a dark blue/green.
• You need this figure for when SET WATER HARDNESS as per P overleaf.
/ N. SETTING THE ELECTRONIC CONTROLLER
• Turn on power and the Magnesio display will say WELCOME.
• The Display is a 2 line display showing both the Model No and also Time and Hardness. The Time
and Hardness will alternate every 10 seconds.
• To finalise commissioning of the conditioner, you need to set both Time (24hr clock in hours and
minutes) and the water Hardness as determined by the amount of drops in your water hardness
test.
/ O. SET TIME OF DAY
• Wait until display says Time of Day. If Time of Day is correct, skip to P. SET HARDNESS.
• Press Up button to show flashing Hours. Please note it is a 24hr clock.
• Press Up or Down button to set Hours.
• Press to confirm Hours.
• After confirming Hours with (), display will show minutes flashing.
• Use Up and Down button to set Minutes.

• Press Up Button to show Set Hardness with no flashing.
• Use Up Button to set number as determined by your water hardness test.
• Press to confirm setting.
/ Q. SET DAYS OVERRIDE
• Apply water hardness drops total from the chart below as Override figure in display.
• Wait until display changes to Override.
• Press Up button to show Set Override with no flashing.
• Press Down button until number corresponds with chart below.
• Press to confirm setting.
/ R. MAGNESIO OVERRIDE CHART
• You have finished the programming.
• The display will now automatically revert back to the alternating display.
• If at any time you need to reset any figure, wait until the display changes to the relevant setting
and then re-programme as required.
/ S. FLUSH CONDITIONER - IMPORTANT
• Place bypass in Service position by turning handles to vertical position (see Page 4).
• Check for leaks.
• Leave a mains tap to run for a minimum of 5 minutes to purge any air and ‘resin dust’ from the
conditioner (resin dust may appear orange in colour).
ALWAYS ENSURE THAT YOU USE MAGNESIUM FLAKES
• Always ensure that the magnesium compartment is always at least half full of magnesium flakes.
The water conditioner will set its own level of water in the cabinet.
• On all MG-1/MG-2/MG-3/MG-4 models, add 1 litre of water to the magnesium compartment on
initial installation only.
If at any time you see excess water in the magnesium compartment going down the overflow, please
call our service team on [phone].

/ T. EXTRA REGENERATIONS
• To start an automatic regeneration, press the left hand button and release, the display will
count down from 15 to zero. If at any time you wish to cancel the count down, simply press
again.
• An automatic regeneration will start shortly.
/ U. BLENDING CONTROL
• If hard mains water is ever needed you can open the blender bypass on the conditioner control
valve slightly – until it takes 6/7 drops of the dark liquid to get a red to green colour change, as per
the original water hardness test.
This blended water setting can only be done when the conditioner is in Service.
/ Further Information
• Do not worry if your conditioner regenerates during the
day. This is the Customer Protect Programme initiating an
additional mini regeneration, as the Magnesio does not
have enough conditioned water to last you until the next
programmed regeneration of 2am.
• A regeneration can last between 51 and 92 minutes
depending on the model. During this time the conditioner
goes into hard water bypass, ensuring a continuous supply of
water.
• A Normal regeneration is programmed to 2am, a time when
little, if any, water is being used.
• To change the regeneration time, simply offset the Time
Setting i.e. to have the unit regenerate 2 hours later, set clock
2 hours slow- see O.
• To ensure the conditioners continuous operation, please do
not let the magnesium flakes drop below half way down in
the cabinet.
