Installation Note: A water filter system/tap, like any product, has a limited lifespan and if not replaced, will eventually fail. Failure can happen 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. We strongly recommend that a drain pan, plumbed to an appropriate drain or outfitted with a leak detector, be used in those applications where any leakage could cause property damage.  We also strongly recommend that the water supply be turned off, upstream to the water filter system/tap, if no one is home for an extended period of time.
INSTALLATION SHOULD BE COMPLETED BY QUALIFIED TRADESPEOPLE.
FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.

How the NTS & NTX Neutraliser Works

Water with a pH level below 6.5 could be acidic, and corrosive. Acidic water leaches metal ions such as iron, manganese, copper, lead and zinc from pipework. This in turn  will elevate levels of toxic metals, cause damage to plumbing and cause aesthetic problems such as a metallic taste or a blue-green stain on surfaces.
The best way to treat the problem of low pH water is with the use of a NTS or NTX Neutraliser.
The media slowly dissolves as the water passes through the bed, raising the pH level to 7 or above.
As the neutralising media is absorbed, periodic topping up is necessary. The lower the pH, the faster the media will be depleted and the longer the contact time required. The  system should be sized according to the pH level and the flow rate required, contact Puretec for a recommendation.
Due to the nature of the upflow system, no electricity or backwashing is required.
NTX systems have the added benefit of a blending/mixing valve to further adjust the pH of the water.
IMPORTANT NOTE : Since the neutraliser media dissolves as it elevates pH level, it will increase the hardness of your water. Installation of a water softener may be  necessary if the hardness becomes a problem.

Before Installation

Professional Installation Required
Installation requires shutting water off to home, cutting home water supply pipe and using a welding torch to add piping and fittings. Specialised tools and skills are required,  this must be completed by a qualified 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. Your dealer will generally perform this service for you, and may send a  sample to a laboratory for analysis and recommendations. Enter your analysis on Page 3 for your permanent record.
pH neutralisers are designed to balance the pH of the water, however it will also increase the level of calcium in the water. This may cause scaling issues and we recommend to contact Puretec for advice.

Locate Water Treatment Equipment Correctly
Select the location of your neutraliser with care. Various conditions which contribute to proper location are as follows:

• Locate in correct relationship to other water conditioning equipment. Contact Puretec for assistance.
• Locate the neutraliser in the supply line BEFORE the water heater.
• DO NOT install the neutraliser in a location with temperatures below 0°C or above 40°C. Temperatures outside these limits may cause permanent damage and will also void the warranty.
• Protect from pressure vacuum with a suitable vacuum breaker.
• For point of entry installations an approved backflow prevention device must be installed.
• Where line pressure exceeds 500 kPa, an approved pressure limiting device must be installed to comply with Australian & New Zealand Plumbing Standards. (Ref.  AS/NZS 3500.1:2021, Clause 3.3.4).
• DO NOT install where water hammer conditions may occur without installing an arrestor.
• Allow sufficient space for installation and easy servicing.

Facts to Remember While Planning Your Installation:

• 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 neutraliser, a larger model MUST be  selected to accommodate the higher flow/volume. Contact Puretec for assistance.

WARNINGS

The control valve, fittings 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 silicon 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. Avoid getting primer and solvent cement on filter system.
• Install grounding strap on metal pipes if required.
• Ensure the system is protected against high pressure and extreme temperatures.

Installation Procedure

Unpack the Equipment
Ensure all parts are present and have not been damaged in transport.
You should have:

• Tank Kit
• Valve Kit
• Media Kit
• Instruction Kit
• Blending Valve Kit (NTX systems only)
  See individual model information page for detailed kit inclusions.

Ensure Water Has Been Tested
Input values into Installation Record on page 3 and the analysis has been inspected by Puretec.

Position the Water Treatment System on a Level Surface
WARNING – THESE STEPS ARE CRITICAL FOR THE CORRECT INSTALLATION OF YOUR WATER TREATMENT SYSTEM.

1. Select the location of your water treatment system with care. Various conditions which contribute to proper location are as follows:

2. Install as close as possible to a drain.

3. The unit must be installed on a surface that is firm, level, horizontal in both directions and fully supports the entire base of the softener. The softener can weigh a  considerable amount when full and the base must be suitable to support this weight.

4. Install in correct relationship to other water treatment equipment. Contact Puretec for assistance.

5. Install the water treatment system in the supply line BEFORE the water heater.
   Temperatures above 110°F (43.3°C) will damage the system and void the warranty.

6. DO NOT install the treatment system in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the warranty.

7. DO NOT install where water hammer conditions may occur without installing an arrestor.

8. Allow sufficient space around the installation for easy servicing. Provide a nonswitched 240V power source for the control valve.

Installing the Mixing Valve (NTX systems)
Install the mixing valve as per the WTV5050 User Guide included with the mixing valve before proceeding to step 6.

Installing the Bypass (purchased separately)
Optional: Install MP100B + PL05MP1 on the outlet to prevent an excess media from coming through the line.

Uninstall the plastic fittings by turning the knob counterclockwise.

Connect the bypass assembly followed by the plastic fittings. Hand tighten the knobs, do not overtighten.

Connecting The System

1. Refer to diagram (below) for correct plumbing of head. Cut the inlet line as required to accommodate the inlet/outlet of the neutraliser. ONLY use thread tape, as liquid  sealants will cause deterioration of the plastic. DO NOT OVERTIGHTEN.

2. After the valve has been connected, remove the fill-port cap using the spanner provided. Add the neutralising media using a funnel (see individual model specifications  for filling order), ensuring that it is no more than 2/3 full. Replace the fill-port cap.
   Note: Overfilling the tank can result in excess undissolved media entering the line. You may have been supplied with more media than required, retain this for future replenishing.

3. Adjust the bypass to allow water flow (refer to Page 13) and turn the water supply back on.

4. The water will initially be ‘milky white’ in appearance. Flush the water through the system until all the air in the lines is expelled, or when the water runs clear.

5. Installation is now complete, and your system is ready for use.

Note: The pH level can be adjusted using the mixing valve on NTX models to achieve the desired level. If the pH is initially over corrected this can be adjusted with a bypass  valve by mixing untreated water with treated water to achieve the desired level (if installed). Testing can be done with a hand- held meter, Puretec PTE20 or similar (not included).

Valve Identification

Maintenance

1. Isolate water supply by closing the inlet valve.
2. Relieve pressure by opening a tap down stream. Remove fill-port cap with the spanner provided. Some water will weep out of the head, however this is normal.
   3. Top-up the media as required, ensuring that you do not exceed the maximum level
   on the tank (more than 2/3 full).
   4. Replace fill-port cap onto the head and tighten with the spanner provided. Open
   the inlet valve, the system is now ready for use.

Media Replacement
The NTS neutraliser sytems use a pure calcium carbonate media. The NTX neutraliser sytems use a pure calcium carbonate & magnesium oxide media. During water usage a specific amount of media is consumed, thus requiring periodic top-ups for a continuous supply of treated water. The frequency is dependent on the pH level and water usage. Always replenish the media before the supply is exhausted. No extra water is required when topping up the media level.
An easy way to determine if the neutraliser requires media replenishment is to place a mark on the outside of the unit at the maximum level of the media when first installed.  Every 2-3 months check the level by shining a light through the tank and compare the current level to the maximum. If you are unable to see through the tank and a dip-test  is necessary to gauge media level, first remove the fill-port cap. Then, using a clean, food-grade rod (with a diameter no more than 5 mm) insert the rod into the crescent- shaped opening in the fill port and measure down to the top of the media. Add more media if the media is more than 2 inches below the mark. See individual Model  Information pages for details.
The media storage capacity is as per the following, and should be no more than 2/3 full.

• The lower the pH (acidity) of the water being treated, the greater the attrition rate of the media and the slower the water should pass through the bed. The unit should be  sized according to the level of pH and existing flow rate.

Personal Protective Equipment
Eye / Face Wear dust-proof goggles.
Hands Wear PVC or rubber gloves.
Body When using large quantities or where heavy contamination is likely, wear coveralls.
Respiratory Where an inhalation risk exists, wear a Class P1 (Particulate) respirator.

Tank Clean-Out (Yearly) – If Required
To help prevent service problems the tank should be emptied and flushed out with a garden hose when dirt and other insolubles accumulate on a regular basis. Shut off water inlet supply and depressurise the system before service.
Steps to follow:

1. Disconnect inlet/outlet connections and remove the fill-port head
2. Turn tank upside down and discard old media.
3. Rinse out with a garden hose.
4.  Reconnect the fill-port head and inlet/outlet connections.

IMPORTANT SERVICING NOTE:
Under normal circumstances removal of the fill-port head assembly should not be required.
However, if it must be removed, disconnect the plumbing attached to the bypass valve first.
Then, rotate the fill-port head assembly to the left or counter clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water to the system  and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease.
Reattach fill-port head assembly by rotating to the right or clockwise until fill-port head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.

Blending Valve Operation (NTX systems)
For blending vale operation information see the Puretec WTV5050 User Guide included with the NTX models. The Puretec WTV5050 Blending Valve can also be purchased seprately.

Bypass Valve Operation – Optional Accessory

Shut Off Mode

Troubleshooting Guide

inlet bypass can be partially closed to allow untreated and treated water. Periodically test treated water pH and open bypass valve when pH begins to drop.
B. Neutraliser fails to increase pH upon installation.| 1.Make sure bypass valve is closed.
2.Test water or have it tested via third party. If high hardness or total dissolved solids (TDS), seek alternate means of treatment such as feeding a solution of soda ash or caustic soda.
C. Neutraliser fails to increase pH after being in service.| 1. Check filter bed for cementing or channelling. Break channelling or cementing with stiff rod or tubing.
D. Excessive pressure drop.| 1.Check untreated water for sediment, silt or sand. Install sand trap or multiple cartridge filter prior to neutraliser.
2.Check the inlet is connected to the port labelled “upflow”.
