Safety & Care Advice
Please note that the use of this product is subject to the Water2Buy General Terms and Conditions available on
water2buy.com and you should read these before going any further. You are treated as accepting these General Terms
and Conditions by using the product in any way.
This water softener’s control valve conforms to the highest industry standards for materials and structural integrity.
Water2buy™ products are for use with microbiologically safe water. Read and follow all safety rules and operating
instructions before first use of this product. If you have questions when installing, operating or maintaining your water
softener, log on to www.water2buy.com/app and watch the user installation video for your product. The approximate
time required to install this unit is 3 hours.
Your water softener is heavy take precaution to prevent injury.
Do not exceed 6.89bar (100psi) water pressure. Do not exceed 40C (104F) water temperature. Do not subject unit to
freezing conditions
Subjecting your unit to these conditions will void the warranty. Read all steps, guides and rules carefully before
installing and using your water softener. Reading this manual will help you get all the benefits from your water
softener. We recommend that a trained professional install this water softener.
Please follow all local codes for plumbing this unit. Follow local electrical codes. Install a correctly sized electrical
bonding jumper between the inlet and outlet pipes when these devices are installed in plumbing systems. Inspect this
unit carefully for carrier shortage or shipping damage before beginning installation of unit.
This system should not be used for treating water that is microbiologically unsafe or of unknown quality. The unit is
designed with the sole purpose of removing hardness. Use only lead-free solder and flux, as required local codes, when
installing soldered copper plumbing. Use caution when ‘sweat joining’ metal pipes near this water conditioning system.
Heat can adversely affect the plastic used in this system and bypass valve. Use only silicone grease for lubrication of
this unit. Do not allow this water softener to freeze. Damage from freezing will void this water softener’s warranty. Do
not store flammable or volatile chemicals near this water softener. For the purpose of plumbing system sizing, only the
rated service (i.e."Normal") flow and corresponding pressure loss may be used. The rated service flow rates are the
flow rates.
Use at least 3 metres of tubing between the outlet of the water softener and the inlet to the water heater. Water
heaters can overheat to the extent that they can send heat back down the cold pipe into the unit control valve. Hot
water can severely damage the softener. A 3-metre total pipe run, including bends, elbows, and fittings, is a reasonable
distance to help prevent hot water damage. A positive way to prevent hot water from flowing from heat source to the
water softener, in the event of a negative pressure situation, is to install a check valve in the soft water tubing from the
softener. If a check valve is installed, make sure the water-heating unit is equipped with a rated temperature and
pressure safety relief valve.
Be sure that local codes are not violated. Do not locate unit where it or its connections (including the drain and
overflow lines) will ever be subjected temperatures less than 1oC (34oF) or greater than 40oC (104oF). Do not install
unit near acid or acid fumes. The use of resin cleaners in an un-vented enclosure is not recommended. Drain line –
Important: If the unit is located more than 6 metres from drain, use 22mm tubing for distances 6-12metres. Purchase
appropriate fitting to connect the 22mm tubing to the 15mm drain connection (v) on the control valve. If the unit is
located where the drain line must be elevated. You may elevate the line up to 1.8 metres providing the tubing length
does not exceed 4.5 metres and water pressure at softener is not less than 2.bar (29 psi).
You may elevate an additional 60cm for each additional .7bar of water pressure. Where the drain line is elevated but
empties into a drain below the level of the control valve, form a 20cm loop at the end of the tubing so that the bottom
of the loop is level with the drain line connection. This will provide an adequate siphon trap. Where the drain empties
into an overhead sewer line, a sink trap must be used. The waste pipe should not be connected directly to the drain; a
15mm air gap should be left between the waste pipe and the drain. The overflow and the waste pipe should not be
joined together.
