Undersink RO System – 5 Stage
MODEL ID: GT1-26-5
Please read through the entire instruction manual fully before commencing installation.
IMPORTANT INFORMATION BEFORE INSTALLATION
Notice:
Water filter systems/taps, like any other product, have a limited lifespan and will eventually
need replacement. Unexpected circumstances may cause them to fail prematurely. To prevent
property damage, it's important to regularly inspect the system for leaks or signs of wear and
replace it as necessary. We strongly advise using a drain pan that is either connected to an
appropriate drain or equipped with a leak detector in situations where leaks could cause damage.
Additionally, if no one will be home for an extended period, we recommend turning off the water
supply upstream of the water filter system/tap.
CAUTION: Do not use with water that is microbiologically unsafe or with water of unknown quality
without adequate disinfection before or after the system.
While the system is designed to support water quality under typical use, supplementary treatment
may be advisable in certain scenarios to assist in maintaining bacteriostasis and managing
potential variations in microbial content.
A 500 kPa PLV must be installed on the property, or between the Cold Water Stop Valve and the
Filter System to limit the incoming pressure to a maximum of 500 kPa (70 PSI). Failure to install a
PLV may void warranty. If a Cold-Water Line Stop Tap (Isolation Valve) is not already fitted at the
point of installation, the plumber should install one.
This system is designed to be installed under the sink by way of connection between the Cold-
Water Inlet and a dedicated drinking water tap. Ensure the installation location is suitable for both
installation and maintenance.
Minimum inlet water pressure 400 kPa is required for this system.
DO NOT USE THREAD SEALANT – ONLY THREAD TAPE WHERE REQUIRED. TAKE NOTE OF
INSTRUCTION MANUAL WHICH STATES WHICH CONNECTIONS REQUIRE THREAD TAPE AND
WHICH DO NOT.

    Technical Overview I. Important Notes For correct operation of this appliance, it is essential to observe the manufacturer’s instructions. Installation must be carried out by a qualified plumber or authorised technician to comply with Australian Plumbing Codes. This system is certified to WaterMark Standards AS 3497:2021 under Certificate Number 23247.

  • Page 4: Quick Connect Fittings

    VI. Quick Connect Fittings Pushfit or quick release fittings are commonly used on water filter systems as they provide a rapid & secure connection without the need for tools. They operate by simply pushing the tube into the fitting, where internal components grip and seal the tube securely.

  • Page 5: Installation

    Due to guidelines, we are unable to wet test these filtration systems before shipping. As a result, the systems are not pressure tested during assembly, which may lead to minor leaks in connections. These leaks can be easily fixed by re-seating the tubing or tightening a fitting. Additionally, since the filters are dry packed, the systems will require flushing before their first use.

    A Pressure Limiting Valve (PLV) is required on the inlet of the filter system. To limit the incoming pressure to a maximum of 500 kPa (70 PSI). Failure to use a PLV may void warranty. II. Drain Clamp Connection The best installation point for the drain clamp is above the S bend (Trap). Alternatively, if you have a double sink and there is a P Trap, you can install it on the topside of the...

    Connecting the RO System I. Tubing Connections This Reverse Osmosis System is supplied with multiple lengths of ¼” filtration tubing with varying colours. While all tubing is the same, the colours can help differentiate which is which and can be helpful when it is time for maintenance or troubleshooting.

    Once the faucet comes to a steady trickle of water (all air has been purged), close the faucet tap. In • doing this, the Automatic Shut-off Valve (ASV) should activate which will cut the incoming water to the membrane, this can take up to 60 seconds. This will cause the drain line to stop flowing and the unit will enter a ‘standby’.

  • Page 13: Service Inspection

    II. Service Inspection All water filter systems have a limited lifespan and should be regularly checked to ensure safe and reliable operation. During routine maintenance, carefully inspect the filter housings for any signs of wear, including surface crazing, cracks, or weakening of the plastic components. An overall system check is also recommended to identify any early warning signs of potential failure.
  • Page 14 Using the Opening Tool (GT17-0), Unscrew the housings one at a time. NOTE: The housings will • be full of water so after you break the seal with the Opening tool, unscrew the rest of the way by hand, keeping the system upright to prevent spillage. Discard the old filters as general waste. Carefully remove any shrink wrapping from the new cartridges and install them into the housings, ensuring the cartridges are centred.

  • Page 15: Replacing Membrane

    Replacing Membrane If the membrane is being changed, disconnect the inlet tubing to the membrane shown below, then • unscrew the cap from the housing to expose the membrane cartridge. Using a pair of gripping tools, pull the membrane cartridge out from the housing – using a back/forth twisting motion can help release the seal.
