IV. What is Standard Filtration
Standard Filtration generally refers to systems designed to remove dirt/sediment & chemicals (such as chlorine) from drinking water. These systems are NOT designed to remove Fluoride or other dissolved salts or minerals from water. These units are generally simple to install and run and have a lower cost to maintain. They help improve the taste of the water whilst removing common impurities.
V. Installation with other Systems
It is common for Pressure Media Vessels to be installed alongside other additional filtration systems for different applications. The most common of these would be a “Big Blue” Sediment/Carbon Filter and Ultraviolet Sanitation System. 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 not standard installations. Installing the GT1-18 as a Calcite Filter: Calcite filters are usually installed on Rain Water Systems to counteract the pH of acidic rain water 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 System. The most common installation set up will go in order of Tank GT1-18 Calcite Filter Big Blue UV House
Installation Introduction
I. Site Preparation
The GT1-18 Vessel must be installed in a vertical position on a solid base such as a concrete slab (500mm x 500mm minimum) in close proximity to the main water line coming into the house (between the pump & house). Ideally you should locate where the cold water enters the building or tees off to the hot water system. Either way, you will need access to modify the pipe work for system installation. Allow enough room to install
a bypass for the filtration system in the event that something goes wrong with the system, or during maintenance so that water can still be supplied to the house.
Example bypass installation, which is strongly recommended with the GT1-18 Vessel. All installations are different so please consult your plumber prior to installation.
The GT1-18 Vessel is UV resistant, however where possible, it is best for the longevity of the system to install the unit under cover, or construct a simple cover for the system to shield it from direct sunlight and weather extremes such as rain, storms and frost. Ensure that you allow adequate clearance above and around the vessel for plumbing fittings and filter maintenance.

II. Installing Connections
The GT1-18’s Runxin Manual Multi Port Valve features standard 1″ BSP Female ports for straightforward installation. It is important that a suitable fitting is used for the installation into the housing port. Dimension and specifications for the are Runxin Manual Multi Port Valve are outlined below. Coupling or union-style fittings are recommended for easy installation and maintenance, to allow the Runxin Valve to be removed and the vessel to be moved if required (i.e. for filling with media/emptying). 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.

III. 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 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 filtration 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.
Plumbing Installation, Start Up & Operation Instructions
I. Plumbing Installation
All installation scenarios may be different so there is more than one way to connect this system. The example provided on page 3 showing a bypass set up would be the most ideal type of installation. The plumber installing this system will determine which installation set up is best suited.
· Ensure that a one-way check valve is mounted before the filtration system. · Control valves should be higher than the drain. · Ensure the backflush is plumbed to drain. Do not directly connect the drain line to sewage to avoid
wastewater contamination. · This system is a refillable media vessel, and as such, will require the head assembly to be
disconnected to allow changing or topping up of filter media. Due to this, it is recommended that you use fittings and installation techniques that are easy to remove for maintenance. · Note the Runxin Manual Flush valve has three settings: Filter, Fast Rinse and Back Wash. Toggle between these settings by moving the position of the valve handle.

II. Filling the Vessel with Filter Media & Start-Up Commissioning
Page | 5
We strongly recommend to position the vessel in the installation location before filling with media once the vessel is filled it will be very heavy and hard to move! Coupling or union-style fittings are recommended for easy installation and maintenance, to allow the Runxin Valve to be removed and the vessel to be moved if required (i.e. for filling with media/emptying).
Calcite/Magnesium Media
Calcite and Magnesium media are commonly used for pH adjustment in Rain or Bore Water.
1. Lower the drop tube (riser pipe) into the vessel, dome end first, and centre it into the depression at the bottom of the vessel. Using the funnel (sold separately), fill the bottom of the vessel slowly with the supplied amount of filter gravel. NOTE: Be careful not to spill any gravel/media in the centre of the drop tube.
2. Add 75kg of Calcite Media (Approx. 3 bags). Ensure the drop tube stays centred during the filling process. If using Magnesium pH Booster (Corosex): a. If the source water’s pH is around 5, add 1/3 of a bag of Magnesium. b. If the source water’s pH is around 4.5, add 1/2 of a bag of Magnesium.
3. Fit the top screen to the Runxin Valve and lock into place. 4. Install the base seal ring then fit the valve to the vessel, ensure that the o-ring stays in place while
tightening the valve. 5. Connect the plumbing to the valve head ready for start-up. 6. Set the valve to the “Back Wash” setting (refer to diagram on page 5). 7. Turn on water and back wash the system for 10-15 minutes, or until the water runs sufficiently clear. 8. After back washing has completed, open the nearest tap downstream of the filter to purge air from
the system. 9. Move the valve to the “Filter” setting. Once the lines have been sufficiently purged of air, close the
downstream tap. Your system should now be fully operational. 10. Optional: Conduct a pH Test after the filter to ensure pH has reached the desired level.
Granular Activated Carbon (“GAC”) Media
GAC media produces a fine black powder which tends to discolour water, and may clog up appliances when first installed. Thus, it will need to be thoroughly backwashed to ensure that all carbon fines are removed. Acid Washed Coconut Carbon is the preferred type of media for use in a media vessel application, as it produces less carbon dust which makes the flushing process quicker and more efficient.
1. Lower the drop tube (riser pipe) into the vessel, dome end first, and centre it into the depression at the bottom of the vessel. Using the funnel (sold separately), fill the bottom of the vessel slowly with the supplied amount of filter gravel. NOTE: Be careful not to spill any gravel/media in the centre of the drop tube.
2. Add Carbon Media to the vessel (Approx. 25kg unless specified otherwise). Ensure the drop tube stays centred during the filling process.
3. Fit the top screen to the Runxin Valve and lock into place. 4. Install the base seal ring then fit the valve to the vessel, ensure that the o-ring stays in place while
tightening the valve. 5. Connect the plumbing to the valve head ready for start-up. 6. Set the valve to the “Back Wash” setting (refer to diagram on page 5). 7. Turn on water and back wash the system for 10-15 minutes, until the water runs sufficiently clear and
the presence of carbon dust has significantly reduced. 8. Then, set to “Fast Rinse” until the water runs completely clear. 9. After back washing and fast rinsing has completed and the water is running clear, open the nearest tap
downstream of the filter to prepare for purging air from the system. 10. Move the valve to the “Filter” setting. Once the lines have been sufficiently purged of air, close the
downstream tap. Your system should now be fully operational.
III.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
Page | 6
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 water supply off to avoid static pressure build up in the filter system. 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. For this we recommend using “Fast Rinse” for 5-15 minutes to circulate the water.
Maintenance
I. Spare Parts
There are generally no parts (excluding consumables) on the system that will require periodic replacement at regular intervals. Below is a list of items that may be applicable:
H1252FRP-2.5 GT36-33K GT36-30 GT5-6 GT5-4 GT5-0F GT5-2F GT5-25 GT5-15
HPF 12″ x 52″ FRP Tank (Grey) with 2.5″ Opening

Corosex pH Booster Filter Media 22.68kg
Replacement Filter Media The lifespan of filter media varies according to feedwater conditions, usage and your unique filtration requirements. Filter media can be replaced under the following guidelines under normal working conditions:
Calcite & Magnesium Calcite & Magnesium naturally dissolve into the water over time, so check the pH every 3-6 months and top up as required. Alternatively, if you have specific ph requirements (i.e. you have highly acidic water and also use magnesium), test your pH ongoing and add more filter media when the pH drops below the minimum desired level (ie. 6.8 pH). 75kg (3 bags) of Calcite Media will provide a full refill for the 12″ x 52″ vessel you should not have to empty the vessel to conduct a re-fill, as the gravel is re-usable. In cases where Magnesium and Calcite are used together, add the calcite to the vessel first, then add the Magnesium on top. Ensure that you do not overfill the vessel to the brim.
· If the pH is around 5, fill the vessel with a ratio of 75kg (3x 25kg boxes) of Calcite to 7.5kg (approx. 1/3 bag) of Magnesium.
· If the pH is around 4.5, fill the vessel with a ratio of 71.25kg Calcite to 10-12kg (approx. 1/2 bag) of Magnesium.
Carbon Carbon which has expired requires replacement, so check your parameters/requirements (i.e. testing for free and total chlorine levels) every 3, 6 or 12 months and replace as required. Simple Free Chlorine testing can be done after the filters to determine if the filters are still removing chlorine adequately from your drinking water. These types of tests are generally inexpensive however for best results, lab tests are recommended. To empty the vessel, you can use a syphon or up-end the vessel please check with local regulations for expired carbon disposal instructions. 20kg (1 Bag) of Gravel and 25kg (1 Bag) of Carbon Media will provide a full refill for the 12″ x 52″ vessel

Reaction
Solution
1. Remove existing tape and apply slightly more tape
do not apply excessive amounts to avoid damage to port.
2. Check the port for a hairline crack or split if there
is one, the cap will need to be replaced, it is not reparable. 3. The caps are 1″ BSP and will require preferably a 1″ BSPT male fitting.
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.
1. If you have a GAC 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. Magnesium is designed to increase the pH. A high
pH reading with magnesium is normal.
3. pH testing equipment can range from cheap test
strips 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. not test strips). 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.
1. The filters are dry packed, the carbons, alkaline
filters will have `fines’ on them.
2. Carbon, Calcite and Magnesium 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 and also allowing the water to stand before drinking can also help allowing the water to `vent’ off 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
1. Air is common whenever the system is opened.
This will dissipate over time as the air flushes from the
system/plumbing.
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 keep flushing until the slipperiness subsides.
