Before installing your Scalemaster Water Softener please make a note here of the water
hardness. This can be done with the Water Hardness Test Strips supplied with your
softener. If you are unsure you can contact your local Water Authority or contact the
Scalemaster Sales office with your postcode.
IMPORTANT - PLEASE NOTE:
• Before you start installing your Softline Water Softener ensure that you have
all the correct parts and tools required to install your water softener.
• Ensure you have the correct installation kit to complete your installation.
• Failure to install your water softener in accordance with these installation
instructions may invalidate your warranty cover.
• Warranty is only valid if the water softener is registered once installed.
• Warranty exclusions include chemical damage to resin, chemical or debris
damage from external sources, site damage or incorrect installation.
• In the interests of continuing product development, Scalemaster reserves
the right to make modifications to the specification, design and
appearance of the unit without notice.

Thank you for choosing a Scalemaster Water Softener
Please take the time to read this installation guide. It will tell you in simple terms how to
install and commission your new Scalemaster Water Softener to begin enjoying the benefits
of softened water.
Before You Start
• Before starting installation, inspect the Water Softener for shipping damage or
shortages. Make sure you have all the necessary tools on hand before starting the
installation.
• Follow all applicable Plumbing and Electrical regulations when installing the Water
Softener. If in doubt, refer to the relevant WRAS Information and Guidance note at:
www.wras.co.uk/PDF_Files/ign9-07-01.pdf
• This Water Softener is not intended for the treatment of water that is microbiologically
unsafe or of unknown quality without adequate disinfection before or after the Water
Softener and is to be used only for potable water.
• Use caution when installing soldered metal piping near the Water Softener. Heat can
adversely affect the plastic control valve or bypass valve system. Be sure all soldered
pipes are fully cooled before attaching plastic plumbing fittings.
• Take care not to strip the threads when tightening plastic pipe fittings. PTFE tape may
be used on connections that do not use an ‘O’ ring seal. Do not allow pipe jointing
compound or sealant to come into contact with any plastic parts.
• There should be a minimum runoff at least 3 meters of pipe between a softener and a
water heater to prevent the possibility of hot water entering the softener unit.
• Use only the power transformer supplied with the Water Softener unit. The mains power
adapter supplied is double-insulated and does not require earthing. Earth bonding
should be applied across metal inlet and outlet pipework of the Water Softener to
maintain earth continuity.
• Observe drain line requirements. The drain line must be a minimum of 12.5mm
diameter. The unit should be above, and not more than 6 metres from a drain.
• Do not support the weight of the Water Softener on the control valve connections or
plumbing.
• Protect the softener, softener drain and all other components from the effects of frost.
Evidence of damage due to freezing will invalidate your Water Softener warranty.
• Keep the media vessel in the upright position. Do not turn upside down or drop. Turning
the vessel upside down or laying the vessel on it’s side can cause treatment media to
enter the valve.
If in doubt contact the Technical Helpline on 07990 064096

IF YOU ARE CONSIDERING INSTALLING YOUR WATER SOFTENER IN A LOFT.
THE FOLLOWING INSTRUCTIONS SHOULD BE STRICTLY ADHERED TO:
Loft Installation
• The water softener may be installed in a loft or roof cavity but must be located within
a safety bund tank of not less than 100 litre capacity. A suitable tank would be a
plastic roof storage tank with an overflow pipe of not less than 22mm diameter.
This tank should also be mounted on a board strong enough to spread the weight
over a load-bearing wall/joists.
Water Line & Bypass Connections
• An external bypass loop should be installed on all Scalemaster electrically operated
water softeners. The external bypass valve loop isolates the Water Softener from the
water system and provides unsoftened water to the water system during routine
maintenance and servicing procedures.
Installation
It is recommended that your water softener is installed by a professional
plumber. This installation guide is written with the professional plumber in mind
and assumes that this person has a working knowledge of hydraulic water
softeners and domestic plumbing systems. Any electrical work required should
be carried out by a fully qualified electrician.
Positioning the Water Softener.
• Measure your Water Softener and the space where it will be installed. Remember to
allow extra space for connecting pipework and access for future servicing and
topping up of salt.
• Keep the distance of the incoming main and drainage to a minimum. 2 metres is
usually more than adequate but this can be longer in circumstances where the water
pressure allows.
• The weight of a Water Softener is greatly increased when fully operational and filled
with salt so this must be taken into account when choosing where to site the softener.
• Your Scalemaster Water Softener is designed to operate effectively with an incoming
water pressure of between 1.0 bar and 6 bar. If your water supply is likely to fall
outside these parameters we recommend that a booster pump or pressure reducing
valve should be fitted accordingly.
Do not install your water softener next to a boiler or other heat source or in an
airing cupboard where the ambient temperature will exceed 40°C.

5
Drain Line Connection
• The unit should be higher than, and not more than 6 metres from the drain. Use an
appropriate adapter fitting to connect 1/2” (12.4mm) plastic tubing to the drain
(discharge) hose connection of the control valve.
• The drain (discharge) hose may be elevated up to 1 meter providing the run does not
exceed 4.6 meters and water pressure at the softener is not less than 2.7 bar.
• Where the drain (discharge) hose is elevated but empties into a drain below the level
of the control valve, form an 18cm loop at the far end of the line so that the bottom of
the loop is level with the drain hose connection. This will provide an adequate siphon
tap.
• Where the drain (discharge) empties into an overhead sewer line, a sink-type U-bend
trap must be used.
• Secure the end of the drain (discharge) hose to prevent it from moving.
Drinking Water
• When fitting your Water Softener, allowance should be made for at least one drinking
water tap that is not fed by the water softener. Where practical this should be at the
kitchen sink but a Utility Room or other suitable alternative will suffice.
• It is recommended that people on a low sodium diet should not drink artificially
softened water. Water used for mixing infant powder for babies must only be taken
from unsoftened water as softened water contains an increased level of sodium which
will not be accounted for in the infant formula.
Brine Line Connections
Check the connections taking care not to over-tighten. Be sure that the regeneration
line is secure and free from air leaks.
Electrical Connection
• For added safety Scalemaster Electric Water Softeners operate on low voltage via a
plug in transformer. Use only the transformer supplied with the softener.
ANY ELECTRICAL WORK REQUIRED TO INSTALL A MAINS POWER SUPPLY FOR
THE WATER SOFTENER SHOULD ONLY BE CARRIED OUT BY A FULLY
QUALIFIED ELECTRICIAN.

Controls: Layout & Operation.
• Large LED Display: A 2 digit LED readout is highly visible for easy reading.
• Easy 3 - Step Programming: Only 3 buttons are required to fully control the softener.
• Camshaft Indicator: A column of windows located on the left of the LED readout
display provides a visual indicator of the camshaft operation.
• Manual Regeneration Button: Initiates either a delayed regeneration or immediate
regeneration depending upon long or short pressing.
• Power Loss Memory Retention: The controller features battery-free Time of Day
retention during loss of power. The time will remain in memory for 6 to 24 hours
depending on the installation. If the memory’s power source becomes exhausted, the
Time of Day will reset to ‘0’ immediately after power is resumed. The Time of Day must
be reset to ensure time of regeneration occurs at 02.00am.
NOTE: All other programmed parameters are stored in the flash memory and are re-
tained during power outages. Flash memory retention is 100 years.

Commissioning
The Water Softener will now need to be placed into operation. Do not put salt into the
brine tank yet.
1. With the supply water for the system still turned off, position the bypass valve to the
‘not in bypass’ (normal operation) position.
2. Press and hold the button on the controller for 3 seconds. This will initiate a manual
regeneration, and cycle to the backwash position.
3. Filling the resin vessel with water.
A. With the water Softener in backwash, open the water supply valve very slowly to
approximately the 1/4 open position. Water will begin to enter the resin vessel.
Air will begin to be purged to drain as the resin vessel fills with water.
B. When all of the air has been purged from the resin vessel (water begins to flow
steadily from the drain line), open the main supply valve all the way. This will
purge the final air from the tank.
C. Allow water to run to drain until the water runs clear from the drain line. This
purges any debris from the media bed. Within the vessel.
D. Turn off the water supply and let the system stand for about five minutes to allow
any trapped air to escape from the resin vessel.
4. Adding water to the salt tank.
Pour 6 litres of water into the Brine (Salt) Tank

5. Checking Brine Draw
A. From the service position press the button to initiate a manual regeneration and
allow the control to move to the backwash position (C1). (to display the C number,
quickly press the button after the cascading lines have started).
B. As the lines start to cascade slowly turn on the water to the softener and allow the
air to purge from the softener.(C1 will last approximately 1 minute).
C. When the control moves to C2 check that the water is being drawn from the brine
(salt) tank.
D. If the water level does not recede, check all brine line connections.
6. If the water level is receding from the brine (salt) tank press the and the clock buttons
together for 3 seconds, the softener will go to C3, repeat this until you return to the
service position (after C7).
7. Turn on a tap plumbed after the Water Softener. Run the tap until the water runs clear.
8. Fill the brine (salt) tank with either granular or tablet salt (approximately 2/3 full is suffi-
cient), Salt should be specifically formulated for Water Softeners.
Congratulations your Water Softener is now fully operational.
