Before Installation
Professional Installation Required
• Installation requires shutting water o to home, cutting home water supply pipe
and using a welding torch to add piping and ttings. Specialised tools and skills are
required, this must be completed by a qualied tradesperson.
Make Sure Your Water Has Been Thoroughly Tested
• An analysis of your water should be made prior to the selection of your water
treatment equipment. Enter your analysis information on page 4 for your permanent
record.
Note: If sulphate level is higher than the nitrate level, contact Puretec prior to
installation.
Install Water Conditioning Equipment Correctly
Select the location of your system with care. Various conditions which contribute to
proper location are as follows:
• Install as close as possible to a drain.
• Install in correct relationship to other water treatment equipment. Contact Puretec
for assistance.
• Install the system in the supply line BEFORE the water heater. Temperatures above
43.3°C (110°F) will damage the unit and void the warranty.
• DO NOT install the soener in a location where freezing temperatures occur.
Freezing may cause permanent damage and will also void the warranty.
• DO NOT install where water hammer conditions may occur without installing an
arrestor.
• Allow sucient space around the installation for easy servicing. Provide a non-
switched 240V power source for the control valve.
Things to Remember While Planning Your Installation:
Before Installation

6 Installation & Operation Manual Copyright © Puretec Pty Ltd 2020
• The control valve, ttings and/or bypass are designed to accommodate minor plumbing
misalignment but are not designed to support the weight of a system or the plumbing.
• Do not use petroleum jelly, oils, other hydrocarbon lubricants or spray silicone anywhere.
A silicone lubricant may be used on the black O-rings but it is not necessary.
• Do not use pipe dope or other sealants on threads. Thread seal tape is the preferred
sealant but is not necessary on the nut connection or caps because of o-ring seals.
• All plumbing should be done in accordance with local plumbing codes. The pipe size for
the drain line should be a minimum of ⅝”.
• Avoid getting primer and solvent cement on lter system.
• Install grounding strap on metal pipes if required.
• Ensure the system is protected against high pressure and extreme temperatures.
• All installation procedures MUST conform to local plumbing codes.
• If lawn sprinklers, a swimming pool, or geothermal heating/cooling or water for other
devices/activities are to be treated by the system, a larger model MUST be selected
to accommodate the higher ow rate plus the backwashing requirements of the
water treatment system. Contact Puretec for assistance.
Installation Note: A water lter system/tap, like any product, has a limited life and may
eventually fail. Also sometimes failure happens early due to unforeseen circumstances.
To avoid possible property damage, this product should be regularly examined for
leakage and/or deterioration and replaced when necessary. A drain pan, plumbed to an
appropriate drain or outtted with a leak detector, should be used in those applications
where any leakage could cause property damage, and/or the water supply should be
turned o if no one is home/present.
