UV Specifications

WARNING
This appliance must be installed directly into a single socket surge protector before being connected to a 240V 10A General Power Outlet (Power Point). It must be a surge protector – Circuit Breakers and Residual Current Devices (RCDs) are not suitable substitutes as they do not protect the unit from power surges.

Danger : Dangerous electrical voltage is present inside the power supply box & chamber. These instructions must be followed closely to prevent serious personal injury. Ensure eye protection is worn when servicing and installing this unit to protect from harmful UV-C Radiation. This radiation can be harmful to eyes and skin, UV lamps should only be used when properly installed in the irradiation chamber. The UV lamp must not be operated outside the chamber.

• This unit must be used only for its intended purpose as described by the manufacturer.
• This unit must be installed in accordance with this manual.
• The unit must be unplugged when not in use, before fitting or removing any parts.
• The unit must be electrically isolated before Maintenance, Cleaning or Lamp Replacement.
• The System will need to be de-pressurised before maintenance.
• The UV lamp is designed for continuous usage to reach full disinfection capacity. Frequently turning the system on/off will reduce the lamp’s effectiveness and may cause the lamp to fail.
• Do not attempt to use this sterilizer if it has been submerged. If this occurs, turn main power off, unplug the electrical connection and then retrieve the unit if safe to do so.
• Do not operate this unit if it has a damaged cord or plug, if it is malfunctioning or if it has been dropped or been damaged in any manner.
• Always disconnect the water supply and completely drain the water purifier if it will be subjected to temperatures below freezing for extended periods of time.

Overheating: For long periods of no flow the power should be turned OFF. If the system is used intermittently, it is recommended to install a Thermal Relief Valve (TRV), which can be purchased separately. Excessive build-up of temperature in the chamber may cause the O-ring to deform and fail, causing leakage which can blow the lamp/power supply causing damage or personal injury. Installing a UV system without a TRV may void warranty – check the Warranty details for further clarification.

Before You Purchase/Open

The system requires specific working conditions to be met before installation, some general guidelines* are listed below. If these conditions are not met, the system may not be suitable for the application and may not function as specified.These systems are designed for use in home applications on Main Water or Tank Water. For applications where raw water supplies are used (E.g. Bore, Dam, Creek) please contact the manufacturer for technical assistance to determine if your application is suitable for these systems.

Before You Begin Installation

The HPF-UV systems come pre-assembled on the bracket with centre joiners installed. These units are batch tested to ensure there are no leaks. Due to transit, fittings and other components may be loosened or damaged – ensure the system is inspected for damages prior to employing a plumber for installation.

• To ensure full germicidal protection, tanks should be treated with HydroSil-ULTRA (Hydrogen Peroxide Water Sanitiser) before the HPF-UV system is installed. After dosing, run water throughout the house (open each tap) and this will sanitise the plumbing within your house. This is required as UV systems are a point of contact sanitiser which do not have any residual effect (i.e., they only kill bacteria when flowing through the UV; UV radiation does not stay in the water as is moves throughout your house). Once this is completed, you can begin installation. The procedure for sanitising the plumbing system is readily accomplished as follows:
  1. Shut off the upstream water supply that feeds water into the reactor chamber and depressurise water system (if applicable).
  2. Remove the pre-filter cartridge and add the recommended dosage of Hydrosil Ultra as per manufacturer’s instructions. (Available at your local re sellers)
  3. Verify that the UV System is connected to the AC power voltage and operating properly.
  4. Open all faucets, fixtures and appliances and allow cold water to run until you are satisfied that the Hydrosil has reached every outlet. Shut the faucets off and leave the solution sit for a period of 30-60 minutes. You must ensure that all taps, including outside faucets, dishwashers, shower heads, washing machines, toilets, hot water heater, etc., and any device or appliance attached to the plumbing system pass the treated water.
  5. Open the upstream water supply and reinstall any filter cartridges (if applicable) into the filter and then you can run the system as per instructions.
  6. It is important to remember that in the event that a UV is briefly shut down for routine cleaning or during power interruptions where water could have passed through the system, the aforementioned pipe disinfection procedure must be conducted again.
• The UV system should be installed after a filter on the return line. This helps ensure that the water is clear of debris and impurities that could inhibit the disinfection process and increase the risk of damage to glass internals. The UV can be installed before a filter, however, it will take longer to work.
• If water pressure is above 12bar, add a PRESSURE REGULATING VALVE on the inlet side of the equipment to protect the Thimble.
• If water demand can possibly exceed the rated flow, install a flow restrictor on the inlet side of the device.

What is Standard Filtration
Standard Filtration generally refers to systems designed to remove dirt/sediment & chemicals (such as chlorine) from drinking water. Standard Filtration and UV systems are NOT designed to remove Fluoride or other dissolved salts or minerals from water. Such units are generally simple to install/run, have a low cost to maintain and help improve the taste of the water whilst removing common impurities.

Product Application: What is UV light and How Does It Work?
UV water disinfection systems are a popular, highly effective, and easy to use way to protect your family from water-borne living organisms. It is trusted by thousands of people worldwide and is widely used in homes, offices, commercial and industrial applications.

Advantages of UV include:

• Effectiveness: Application of UV light triggers a reaction almost instantly; more effective than chlorination and other water disinfection systems on a wide range of pathogens.
• Safe and chemical-free: UV light does not result in the creation of harmful disinfection by-products; UV does not alter water chemistry and its constituents, such as pH, taste, odour, colour etc.
• Low Cost: Capital cost is low and operating cost is low compared to alternative disinfection methods.
• Simple to install and operate: no moving parts to wear out; installation flexibility.

CAUTION: UV light is not visible to the human eye, but is harmful to eyes and skin.
UV light is comprised of electromagnetic radiation of wavelengths ranging from 100 to 400 nanometers (nm). The UV spectrum is divided into four regions, which are designated vacuum UV, UV-A, UV-B, and UV-C. UV-C. Short-wave ultraviolet occurs between 200-280nm and the optimum UV germicidal action is at 265nm. It has strong disinfection ability to kill microorganisms by altering or disrupting their DNA or RNA without the need for chemicals.

Installation with other Systems

It is common for UV Systems to be installed alongside other additional filtration systems for different applications. Below are some example scenarios. NOTE: These are just guidelines and may be different depending on the requirements of the job. Check with the client or supplier as to which type of installation order is required for non-standard installations.

Sediment & Carbon Filters: Sediment filters can reduce sediment as fine as 1 Micron, whilst Carbon Block filters can reduce sediment as fine as 0.5 Micron. Carbon Blocks are also particularly effective as adsorbing taste and odour molecules, and can provide a slight improvement in water clarity.

Calcite Filter: Calcite filters are usually installed on Rainwater Systems to counteract the pH of acidic rainwater which usually causes green/blue staining in the water or on fixtures. The calcite filter is usually installed as stage 1 as it is a back washable media vessel, followed by the Big Blue components of the HPF-UV System.

Water Softener: Water softeners are common on both mains water and also bore water installations. For bore water installations it is best to check with the supplier as to the installation position and any other requirements such as flow controllers and float switches. The most common bore water installation will go in order of Bore  Softener  Tank  Calcite Filter  HPF-UV  House

Installation Introduction

Site Preparation
The HPFUV System will need to be installed on the water line between the water supply and your house. Ideally if you can find where the cold water enters the building or tees off to the HWS. Either way, you will need access to modify the pipe work to install the system in place.

Allow enough room to install a bypass for the filtration system. If something goes wrong with the system, or during maintenance you can still get a water supply to the house. Below is an example of a bypass installation.

The HPF-UV System is weather resistant, however, where possible it is best for the longevity of the system to install the unit undercover, if possible, to shield it from direct sunlight and weather extremes such as rain, storms, and frost.

Stainless Steel Enclosure
The Stainless-Steel Enclosure & Frame of the HPF-UV system features a robust stainless-steel frame & thick heavy duty mounting plate for the filtration. The front cover is a sleek & stylish brushed chrome finish with premium laser etching rather than plastic stickers/labelling to blend in with a more modern and upmarket style home. The top cover has a toughened glass viewing window for easy monitoring of the UV system and the pressure gauges. Durable automotive grade 3M™ compressed foam tape lining fixed to the joins to reduce metal on metal contact and reduces the chance of water and dust from entering the top section. Toolless fixing screws are used to mount the front cover and top cover in place which can easily be removed by hand OR a flat head screwdriver.

System Installation & Mounting
NOTE: All units are quality tested from the factory. When you receive your system, open package to check all components are inside (Reactor Chamber, UV Lamp, Thimble (Quartz Tube), O-ring, Electronic Ballast and Support). Check the rated working pressure for operation recommendations. Install sterilizer equipment in a readily accessible and well-lit location to facilitate inspection and maintenance. On all units allow sufficient head-space to change the UV Lamp and Thimble (typically leave a maintenance space equal to the overall UV system length) and other parts.

The system is constructed from Stainless Steel and has two keyhole mounts at the rear of the top plate for mounting the unit. Allow enough space on either side for the plumbing connections and ensure there is enough space in front of the unit to allow easy removal of the front/top covers and for maintenance. Also allow at least 500mm height clearance for the UV lamp installation & maintenance. The mounting location will require a 10A GPO within ~1.5m from the left side of the system for the UV power supply. If mounting on an uneven surface (such as rough brick), it is recommended to install a spacer behind the mounting holes, so the unit is sitting slightly off the wall to allow easier installation & removal of the top cover.

Installing Connections
The HPF-UV system has a standard 1” Female BSP port for the inlet connection into the stage 1 Big Blue filter housing. The outlet point from the UV system has an internal and external thread to choose from depending on the installation requirements (i.e. 1” BSP male or ¾” BSP female).

DO NOT use any type of liquid thread sealant as this will cause the cap to split shortly after it cures – warranty will not cover this.
Thread tape is the only form of sealing material permitted for use on these housings. Alternatively, you can also use a suitable 1” BSP fitting with an O-ring for sealing.

Filter Protection
If there is no Pressure Limiting Device (PLV) installed on the main line incoming to the house to limit the water pressure to 500 kPa, you will need to install one prior to the UV and any pre-installed filtration system to reduce the pressure in compliance with Australian Plumbing Codes & HPF Warranty. Failure to do so may cause excessive pressure & potentially damage the system.

It is recommended that an anti-water hammer device is installed on the house to dampen water hammer commonly caused by washing machines. It is best to install these devices at the point of hammer such as on the cold-water line at the washing machine or dishwasher.

Pressure Gauge Installation
The HPF-UV system is supplied pre-fit with gauges, if the gauges are to be removed or replaced, follow the below.

Kit Contains : Opening Spanner, Pressure Gauges (If applicable), Gauge Port Bungs, O-Rings
Install with Gauge Plugs: The housings are supplied with a thin o-ring is a zip-lock bag. Install this o-ring into the gauge port then screw in the gauge plugs firmly without thread tape.
Install with Pressure Gauges: When installing pressure gauges, use the thin o-ring supplied in the zip-lock bag, the O-ring is to go in the port at the bottom – NOT around the thread of the gauge. Firmly hand tighten the gauge without the use of thread tape – Do not overtighten the gauge.
NOTE: If there is no reading on the pressure gauge, it is likely that the gauge is too tight – causing the o-ring to obstruct the hole on the gauge.
If the o-rings do not provide an adequate seal, you are permitted to remove them and use 6 to 8 wraps of white plumber’s tape. Excess thread tape or thread glue/sealant will cause the port to split.

Cartridge Installation
Cartridges should be installed in order of: Pleated Before Polyspun, Polyspun Before Carbon, Highest Micron Before Lowest Micron. As an example, a common filter set would be a 5uM Polyspun Sediment Filter, followed by a 5uM Silver Carbon. You would install them in that order as per the above guideline.

Cartridges will need to have the outer plastic shrink wrapping removed before being installed. Maintain minimal contact with the surface of the carbon filter, handle by the end caps only to avoid contamination as carbon will absorb smells and oils from the skin. NOTE: Cartridges may be supplied already inside the housings for transport, however they will still be wrapped in their original wrapping as per regulatory guidelines. MAKE SURE TO REMOVE THE

WRAPPERS BEFORE SCREWING UP THE SUMPS!

Gently lower the cartridge into the blue sump and locate the filter so the stem in the bottom of the sump inserts into the centre hole of the cartridge. Do not drop the filter in as this centre stem may break the plastic caps of the filters. Once the filter is located, screw the sump into the cap (in a vertical position). It can help to wobble the sump to help the filter locate into the guide lugs in the top of the cap.

The caps should screw up rather smoothly with little resistance so it is usually suitable to firmly hand tighten the housings. If you encounter resistance before the housing is more than ¾ tightened you may not have the cartridge aligned with the guide lugs; remove the sump and line it up correctly before tightening. An opening spanner is provided with these systems and is only required for installation if hand tightening is not easily achieved or if slight leaking occurs. It is important not to overtighten the housings as this can lead to excessive stress on the cap thread which may cause damage to the housing long term. The spanner can be used to help unscrew the housing when filter changes are required as the housings are usually more difficult to unscrew over time being installed.

Ultraviolet System Installation

Thimble (Quartz Tube) Installation

Due to the fragile nature of the thimble, care must be taken when handling and installing the thimble and lamp. The below steps are for horizontal installations.

1. Remove the knurled nuts from either end of the UV chamber (shown below).
2. Wearing clean gloves or handling with a micro-fibre cloth, remove the thimble from the packaging and check for any marks or blemishes. Insert the glass thimble into the chamber from the top (see picture right). DO NOT DROP THE THIMBLE INSIDE THE CHAMBER AS IT WILL SHATTER.
3. Allow equal parts of the thimble to be exposed from each end of the chamber and slide the O-Rings over each end of the glass (shown below). Be careful not to drop the glass at this point. Once the O-rings are seated, this will assist in holding the glass in place. It is recommended to put something soft underneath the system just in case the glass does slip through, as this it may help prevent the glass from breaking if dropped.

When the O-rings are seated, firstly loosely install the bottom nut and then the top nut until you feel resistance. Simultaneously tighten (by hand) the top and the bottom nut equally to keep the thimble centred in the chamber. Caution: Do not apply any thread tape, grease, or sealant as this will void the warranty. Overtightening the nuts may cause the thimble to crack.

You can look through the open end of the nut to see if the o-ring is seated correctly or feel this with your fingers (shown below). There should be a slight gap between the end edge of the thimble and the recessed stop-end of the knurled nut.

If you see that the thimble is hitting the stop end of the top nut (i.e. glass on metal), stop tightening the nuts because it is likely that the bottom nut has caused the thimble to shift off centre. You will need to loosen off the bottom nut and push the glass back down before continuing with tightening. If you experience issues with this, please contact the distributor or manufacturer for assistance.

When following the next commissioning steps, take the time to check the chamber for leaks once it is pressurised. If a leak occurs, the knurled nuts may need to be tightened slightly. A gripping tool can be used if required if the stop-end is not in contact with the glass. The thimble should be bone dry before the UV lamp is installed. It is extremely important that there are no slow leaks, as over time, these will fill up the thimble with water and cause a short in the lamp, which can result in injury or damage to the lamp & ballast. NOTE: Damage caused by leaking or defective installation is not covered under warranty.

UV Lamp Installation

Once the chamber has been pressure tested and there are no water leaks, the lamp can be installed. It is usually recommended to complete step 1 to 4 of I. Plumber Commissioning (below) before installing the lamp.

1. Drop the spring into the thimble chamber. The spring should sit at the bottom of the thimble. This prevents the UV lamp from falling/hitting the bottom of the glass, and keeps the lamp in the correct position for the power connection.

2. Remove the lamp from its protective wrapping & inspect for damages. Before the lamp is installed, the chamber, thimble and surrounding plumbing must be dry and free from water or leaks. Plug the ballast (power supply) into a certified single socket surge protector, then into a 240V 10A GPO. Ensure the ballast (power supply) is turned OFF at the wall. Note: No warranty will be covered for a blown lamp if the
   ballast is not plugged directly into a surge protector.

3. You will need to connect the ballast connection to the lamp prior to lowering the lamp into the thimble. Firmly hold the white cap of the UV lamp and the connection of the Ballast (see picture below), then push (wiggle) the power supply connection onto the UV lamp pins. NOTE: There is a long and short side of the pins so they will only go into the power supply one way. Ensure the connection is firm and plugged in all the way.

4. Lower the lamp carefully down into the thimble until the lamp makes contact with the spring (as shown to the right). Then, gently slide/wiggle the white cap over the knurled nut.

5. Connect the Green/Yellow earth wire to the small nut (per the below) and finger tighten the nut over it to hold it in place.

6. At this point the lamp should be tested briefly to ensure it is working and the connection is sound. Use appropriate Safety Eyewear for this step.
   a. You can check that the lamp has illuminated by unscrewing the RED plug on the
   White UV Connection Cap, or by carefully lifting the White Cap/UV Tube up (as shown to the right).
   b. Keep your hands clear of the system and turn on the power for 5 seconds to allow the lamp to illuminate. Do not look directly at the lamp without eye protection.
   c. Confirm that the lamp lights up correctly, and the ballast is showing a green light to signify that the lamp is running correctly.
   d. Replace the red plug or slide the white cap back over the knurled nut.

7. When you are ready to start 24/7 UV Sanitation, turn on the power supply and leave it on.
   a. If there is a green light (per Ballast Operation – Working Conditions), everything is running correctly. If not, turn the power off, check for leaks and refer to Ballast Operation/Troubleshooting to diagnose the issue, or contact the supplier.

Ballast Operation

This appliance must be installed directly into a single socket surge protector before being connected to a 240V 10A General Power Outlet (Power Point). It must be a surge protector – Circuit Breakers and Residual Current Devices (RCDs) are not suitable substitutes as they do not protect the unit from power surges.

To guarantee user safety, this ballast features complete control and protection functions which are caused by.

1. UV Lamp exceeding life cycle (365 Days).
2. UV Lamp Failure.
3. Working beyond rated voltage and load.

This ballast is designed to work with germicidal UV lamps. Do not mistake the input/output wire to avoid ballast failure.

• Ensure the voltage is within the specification of the ballast.
• Match the UV lamp with the power output of the ballast.
• Ensure the connections (plugs) are fitted correctly. Connect (screw) the earth wire to the lug on the bottom of ballast (power source) as shown (picture to the right). The earth wire must be affixed securely.

WORKING CONDITIONS:
The Lamp and Ballast are working correctly when the Green LED Indicator Light shows:

• Display Screen – Press the “SELECT” button (for 2 seconds) to toggle between the Lamp Life Remaining (Days) Default Display Screen and the Total Running (Days) Ballast Operation Time:
• Lamp Life Remaining (Days) Default Display Screen – By default, the display screen will show the lamp life, which counts down from 0365 to 0 days. Once the lamp life timer reaches 0, the ballast will alarm to remind you to change the lamp.
• Total Running (Days) Ballast Operation Time – Press the switch button (for up to 2 seconds) to display the ballast operation time, which counts up from 0 to 9999 days. After 10 seconds the screen will return to the default display.

LAMP REPLACEMENT DUE:
End of Lamp Life/UV Lamp Replacement Alarm: Once the Lamp Life Remaining timer reaches day 0, the digital display will show “A3”, the Red LED Error light will flash and an audible alarm will sound (beeping). This indicates that it is time to replace your UV lamp.

Temporary (7 Day) Alarm Pause/Cancellation : If the UV lamp cannot be immediately replaced, you can temporarily pause the alarm by pressing the “SELECT” button for 5 seconds until the buzzer sound stops. This will reset the Lamp Life Remaining display to 7 days, however, the display will continue to show “A3” and the Red Error LED Light will still show. Once those 7 days are up (i.e. lamp life reaches 0), the alarm will re-start. The ballast will provide 4x 7-Day alarm cancellations (for a total of 28 days), after which point the alarm will alarm will not stop until the lamp is replaced.

Lamp Change/Ballast Reset:

• Disconnect the power supply (See Part III: Installing New Lamp for detailed instructions on changing the Lamp).
• Remove the expired/failed lamp, and install the new lamp.
• Press and hold the “SELECT” button for 15 seconds – at the 10 second mark the display will show “RSET”, and after continuing to hold the button for a further 5 seconds, the display will then flash “0365” and give off an audible beep. Release the button and the timer is successfully reset.

ERROR/FAULT CONDITIONS:
Whilst it is usually the lamp that requires replacement, please refer to the below guidance along with the Troubleshooting section of this guide to diagnose which element requires replacement.

LAMP FAILURE : The Lamp has failed when the Red LED Indicator Light shows and/or the system is alarming. Note: The Lamp Life will display “0”, but the Total Running (Days) count will continue.

BALLAST FAILURE: The display will be totally blank if the ballast has failed.
Ultraviolet Disinfection Water System are designed for continuous operation and frequent switching will reduce Ultraviolet radiation and service life. Do not electrically cycle (i.e. do not turn on/off) the UV unit more than THREE

on/off cycles in a 24 hour period. If the water to the house in not going to be used for over 48 hours, the UV system should be turned off to prevent overheating in the chamber. For periods of time over 1 week, the above also applies, however we would suggest briefly flushing the system before use (allow the first few minutes to run down the drain) specifically for drinking water. Allow 15 minutes for UV lamp to achieve full operating capacity before using the water.

System Start Up & Operation

Plumber Commissioning
When you are confident that the system is correctly installed, do the following steps to start up the system and commence the flushing procedure.

1. Open a tap downstream from the system to allow air to bleed from the plumbing – if this is not easily achievable disregard, just note that sputtering may occur more prevalently in the house until the air has vented from the lines.
2. Close off the bypass and open the system valves to allow water to flow through the system, depress the red button on top of the 1st housing until water comes out (to bleed the air), repeat for each housing inline.
3. The water coming out of the system will likely run cloudy or discoloured temporarily which is normal as this is the fines coming off the carbon filter.
4. Shut off the downstream tap and allow the system to hold under static pressure and check for any leaks in the filter plumbing connections.
5. While the filter is new, there may be some slight taste issues with the water (such as a metallic or ‘chemical like’ taste. This is normal and is the reaction that activated carbon has with water when the filters are new. Flushing the filters will help reduce the time until the water is back to normal taste. The metallic taste is usually due to the high pH that is created due to this reaction, it is only temporary and is usually gone within 1 week from installation if not sooner.

Turning the System On/Off
This will depend on the style of bypass that is installed on the system. Refer to the above diagrams of a bypass in service and bypass position.
If the water to the house in not going to be used for over 48 hours, it is recommended to turn the system into bypass mode to avoid static pressure build up in the system. The UV system should also be turned off to prevent overheating in the chamber. For periods of time over 1 week, the above also applies, however we would suggest briefly flushing the system before use (allow the first few minutes to run down the drain) specifically for drinking water.

Maintenance

Stainless Steel Enclosure + Filter Housing Replacement Parts
There are generally no parts (excluding consumables) on the system that will require periodic replacement at regular intervals. Below is a list of parts that may be applicable:

• GT8-13G                             20” x 4.5” Housing (Includes Cap)
• GT8-11G-CAP                    BB Cap 1” Ports Suit GT8-11G + GT8-13G
• GT19-35SC                         1” Poly Nipple Joiner with O-Rings

• GT19-127                           ¼” Gauge Port Stopper
• GT23-1LS                            BB O-Ring
• GT17-2LS                            BB Opening Spanner

Replacement Cartridges
Cartridges have a varying life span but generally can be replaced under the following guidelines under normal working conditions. For clean water supplies (commonly found in Metro locations on the E & SE coast of Australia), filters should generally last up to 12 months. For harsher water conditions (high hardness, scale and TDS) commonly found in rural areas or the North, West and South parts of Australia, filters may need to be changed every 6 months. Filters that are exposed to raw water sources (rain, tank and bore water) may be more susceptible to clogging due to sediment, and may be prone to bio- fouling (given that bacteria breeds on carbon ash).

NOTE: Usage will also be a factor for filter changes – if your pressure begins to drop and the water slows down through the filters it can be an indication that the filters are blocking and may be due for a replacement. These guidelines are based on appropriately sized/quoted systems for the intended application. Systems purchased without recommendation by the supplier may not perform to the above expectations.

Testing Filters
Differential pressure is a good test to determine if the filters are beginning to block and need replacement. When new filters are installed, record the pressure on each gauge while the water is static (no flow) then again measure the pressure with an outlet running (such as a shower). This will give you a baseline for static and flowing differential pressure. There is no set rule as to when filters need replacing due to high differential loss, it more comes down to personal preference. Filters should be replaced at least every 12 months.

UV System Replacement Parts & Maintenance
The 48W lamp in this system is rated for an effective lifespan of 9000 hours (12 months). They are designed for continuous running, not for intermittent operation. Lamp replacement is recommended every 9000 hours of operation (approx. 365 days of constant runtime). After 9000 hours, the lamp may still light, but the UV intensity has diminished. Cleaning of the Thimble is recommended once every 3-6 months with alcohol or a mild detergent.

1” BSPT male fitting.

Pressure Gauges Not Showing a Reading| 1. Obstruction| 1. If there is no reading on the pressure gauge, it is likely that the flat washer was not removed, or the gauge is too tight – causing the washer to obstruct the hole on the gauge. Loosen the gauge to correct

this.

Leaking from Gauge Port| 1.  Not tight enough

2.  Missing O-Ring

3.  Cracked port

| 1.  There can be a fine line for these gauges to seal, if required, remove the seals and use thread tape as directed previously.

2.  Install the O-ring into the port and try again

3.  If there are any signs of damage to the port it may need replacing with a new cap.

No Water Flow| 1.  Valve Position

2.  Insufficient pressure

3.  Damaged or Blocked Filter

4.  Filter Wrapping

| 1.  Check that the bypass and service valves are in the correct position. Ensure the mains is also turned on.

2.  Check the incoming water pressure and ensure it meets the requirements of the selected filters. NOTE: some filters require higher pressure to operate (carbon filters).

3.  Isolate each filter by process of elimination to determine which filter is not allowing water to pass. Check for damages. The filter may also need replacing due to being blocked by some form of contamination.

4.  Ensure the filters are unwrapped before

installation.

High pH Reading| 1.  Carbon Filter

2.  Insufficient Testing Equipment

| 1.  If you have a GAC or Block filter (Carbon), this will naturally increase the pH of the water. pH is the measure of Hydrogen in the water and this hydrogen will vent off the water if you leave it to stand and the pH will then drop back down to the normal level.

2.  pH testing equipment can range from a cheap test pen right up to lab grade equipment. Before coming to a conclusion on pH issues, it is best to ensure the equipment used to measure the pH of the filtered

water is of high standards and suitable for reading

 |  | pH levels in lower EC water (i.e. The guy at the pool shop is not going to cut it). We have access to high quality testing equipment and frequently test our units and conduct research. If you feel that there is an issue with your pH, please contact us.
---|---|---
Strange taste to the water (New System)| 1.  Residue

2.  pH Alteration

3.  Contamination

| 1.  The filters are dry packed, the carbons, alkaline filters will have ‘fines’ on them.

2.  As previously stated, Activated Coconut carbon will react with the water when new and will increase the pH. People who are not accustomed to higher pH water may notice a strange taste/sensation due to the large variance of pH. Flushing the system will help stabilise the pH from the system and also

allowing the water to stand before drinking can also help allowing the water to ‘vent’ the pH

3.  Bacterial contamination is highly unlikely, but not impossible. If there is a strong ‘foul smell’ or organic taste to the water, it is possible that there is some form of contamination. Contact us straight away so we can rectify (or diagnose) the problem if there is

one present.

Cloudy Water| 1. Air in water| 1. Air is common whenever the system is opened. This will dissipate over time as the air flushes from the system/plumbing.
Slimy Feeling Water| 1. Activated Carbon Reaction| 1. This is a common symptom with activated coconut carbon. It gives the feeling of ultra-softened water

and can feel slimy and also cause soaps to have an increased lather making it harder to rinse off. This is only temporary and does not happen with every

installation.

Ultraviolet Sanitation System
Leaking from Chamber| 1.  O-Rings Not Seated

2.  Knurled Nut too loose

3.  Damaged Thimble

| 1.  If there is any issue with the o-ring in the way they are seated this will need to be fixed. Remove the thimble and repeat steps 3 – 5

2.  If the nut is not tight enough, the o-rings will not have a good enough compression and will cause a leak. Slightly tighten up the nut until a watertight seal is achieved. It is better to tighten slightly at a time to prevent overtightening.

3.  If there is a crack or hole in the thimble, it will fill from the inside out. Turn off the water, carefully remove the thimble and replace with a new one. If the thimble releases and shards of glass, this chamber and downstream plumbing will need to be thoroughly checked and any glass removed before

re-connection.

High Water Temperature| 1. Low Flow Rate| 1. If there are periods of low water usage or the water is allowed to stand for long periods of time, the water may be prone to heating up and may become lukewarm or hot in extreme cases.

Generally, this only occurs on systems that have a

 |

2. Oversized System

| short distance between the outlet and the point of use. Whole house systems have a larger length of cold plumbing pipes downstream.

2. If the system is too large for the application it is likely that even with frequent water usage the water does not get a chance to cool down effectively. If there are significant fluctuations in usage or flow rates, it is good practise to instal a thermal relief valve sold separately on the outlet of the UV chamber which can bleed water from the chamber

and keep temperatures below 56°C.

---|---|---
Hot SS Chamber| 1. Low Usage| 1. As Above, if the water is allowed to stand for periods of time the chamber will heat up naturally. This is normal, however if the heating is excessive to the point where it is causing damage to the chamber or surrounding fixtures, a thermal relief valve should

be fitted.

Ballast is alarming| 1.  Lamp Failure

2.  Interrupted power supply

| 1.  Usually if the ballast is alarming and showing a red flashing status indicating light, the lamp has failed, and it will require replacement. Before replacing a lamp, it is best to check firstly for an external cause for lamp failure, turn off the power then check for water ingress from either rain, or leaks or any signs of moisture or condensation in or around the electricals. Due to the elevator temperature of the lamp, high humidity may cause condensate to form. If there are no signs of leaking, check for signs of shorts or charring on the lamp connection with the ballast. lastly inspect the tube to see if there are any dark patches or if the filaments are burnt out.

2.  Sometimes the ballasts may trigger failure alarm if the connection to the lamp is interrupted or perhaps the connection is not solid enough. If the above steps reveal no faults and the lamp is still working, turn the power off for five minutes, check connections and then turn it back on to see if the

fault clears.

No Lights on Ballast| 1.  Ballast failure

2.  interrupted power supply

| 1.  in the event of a large surge it is possible that the ballast failed. This can also occur from shorts and water ingress. cheque for signs of a short around the lamp connexion end. The ballast will need to be replaced. The UV lamp may also have blown at the same time or could be the cause for the ballast failure. for safety it is best to replace both the lamp and ballast together. If it is within warranty. Please contact the manufacturer for further instructions.

2.  Check the wall socket with a different electrical appliance to cheque if the GPO is functioning. Also check your circuit breaker to see if any switches are

off.

Lamp is working but the

ballast is alarming

| 1. Faulty lamp| 1. The lamp may be lighting up but not working at its

full capacity which may be caused by it not drawing

 |

2. Faulty ballast

| enough power from the ballast. The lamp will require replacement. Turn the system off, check connections and turn back on to see if it fixes the alarm.

2. The ballast could have a problem with the lamp failure protection and may require replacement. Turn the system off, check connections and turn back

on to see if it fixes the alarm.
