/ MONARCH PRO-FLO SERIES WATER SOFTENER PROGRAMMING &
INSTALLATION INSTRUCTIONS
Thank you for choosing our water softener. 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 salt 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 SOFTENER - Fig 1
• 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 softener 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 softener within a kitchen cupboard, loft etc. ensure that the base/floor is adequately
supported.
• If the softener is being installed in your loft, 1st, 2nd floor etc, it is strongly recommended to house
the softener within a 25-gallon plastic tank and insulate well. Monarch take no responsibility of
any water damage etc if this recommendation is not applied.
• The overflow on the plastic tank should be below the overflow of the softener and a minimum of
¾” in size. Failure to install the softener in a suitable tank will void the warranty.
/ C. CHECK VALVE
Softened water for drinking or food preparation is category 2 which requires a single check valve type
EA or EB.
/ D. DRINKING WATER FACILITY - See Installation Requirements Diagram
In compliance with U.K. Water Regulations a tap for drinking water purposes should be left on the
hard water supply.
/ E. MATERIAL CHECK LIST
Ensure all installation components comply with appropriate water regulations.

/ F. INTEGRATED BYPASS OPERATION
/ INSTALLATION
1. Rotate the handles by hand or use a bypass tool
2. The water supply will be in Bypass when the handles are horizontal
3. The unit will be in Service when the handles are in the Vertical position
4. When the unit is in the Service position, it is available to take raw water and filtered water
samples for testing at the water taking port on both sides of the bypass
5. Insert the meter sensor into the meter sensor hole
/ NOTES
1. Water pressure: 1.5 - 5 bar
2. Operating temperature: is 2-49°C
3. Only use food grade silicon grease for maintenance, any other kind of grease will affect the
lifetime of the bypass.
4. Do not remove the clips when the system is operating, relieve the pressure before
removing the clips.

/ G. INTEGRATED BYPASS INSTALLATION (MMB063)
1. Remove both salt lid and main cover by lifting off the salt lid and sliding the back cover
backwards and lifting off, this will allow access to the inlet and outlet connections.
2. Remove the flow meter cable by unclipping it from underneath the connector assembly.
3. Remove the two grey side panels and unscrew the two screws and brackets.
4. Remove the 2 grey clips from the back of the softener. The inlet and outlet connector
assembly is now ready to be removed, to do this pull it out of the inlet and outlet connections.
5. Grease the O Rings on the integrated bypass and insert the bypass in place and reconnect the flow
meter cable.
6. The new integrated bypass comes with metal brackets and screws. Use these to attach the bypass to
the valve body.
7. Remove the connectors from the the old connector assembly and insert them in to the new bypass
connection, then reattach the grey clips grey side panels back into their slots.
8. The bypass is now fitted, please place the grey cover and salt lid back on top of the softener and
continue with installation. 5

/ H. 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 1.5bar.
• 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 salt

FIG 2
DRAIN ELBOW
/ K. 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.
• Softened water will have no adverse effect on a septic tank.
• Under no circumstances should the softener drain and overflow share the same pipe. This could
lead to foul smells entering the salt cabinet from the main drain via the overflow. Also if the
common drain ever gets blocked, the regen water can re-enter the softener via the overflow pipe.
/ L. OVERFLOW CONNECTION - Important
• 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.
/ M. 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 ‘soft’ mains tap i.e. utility room cold tap or wash hand basin in
a bathroom. Check all connections for leaks.
/ J. INLET & OUTLET CONNECTIONS - See Fig 2
• Remove the main cover to access 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.
• We recommend you fit the elbow end of the hose to the
inlet/outlet connection points on the softener.
Under no circumstances use washing machines hoses or
plumb the softener in solid copper pipe.

/ N. 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.
/ O. 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 Roverleaf.
/ P. SETTING THE ELECTRONIC CONTROLLER
• Turn on power and the softener 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 softener, 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.

/ T. BLENDING CONTROL – Blue/Green Stains
• All our water softeners are factory set to produce water that is 100% soft. If you require slightly
blended water – recommended on Combi/Condensing Boilers and in areas of hard water that have
a green/blue build up in the scale – open blender bypass on left hand side of softener 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.
/ NOTE
This blended water setting can only be done when the softener is in Service.

/ Further Information
• Do not worry if your softener regenerates during the day.
This is the Self Protect Programme initiating an additional
mini regeneration, as the softener does not have enough soft
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 softener 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 Q.
To ensure the softeners continuous operation, please do not
let the salt drop below half way down in the cabinet.
