System Start Up & Operation
I. 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 1
st
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.
II. 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
I. Stainless Steel Enc 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
GT16-3S
60mm Bottom Mount Pressure Gauge
GT19-127
¼” Gauge Port Stopper
GT23-1LS
BB O-Ring
GT17-2LS
BB Opening Spanner
II. 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).
