Installation

This system comes complete with an installation kit enabling it to be connected to 15 mm (½”) copper pipe (cold supply only – hot water should be filtered prior to heating). Included is a control valve incorporating backflow prevention, anti hammer, flow control and pressure limiting capabilities according to The Australian Standards in full compliance with the relevant laws.
Note: the PLV is standard in selected systems.

Installation Note: A water filter system/tap, like any product, has a limited life and may eventually fail. Also sometimes failure happens 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. A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage, and/or the water supply should be turned off if no one is home/present.

Installation Requirements

1. 15 mm (½”) cold water line.
2. Mix/Max pressure: 300 – 600* kPa.
3. Min/Max temperature: 0° – 38 °C (protect from freezing).
4. Suitable location for faucet.

Alternative fittings may be required if being connected to anything other than 15 mm (½”) copper pipe. No electrical or drainage requirements needed. *If pressure exceeds 500kPa an approved pressure limiting device needs to be fitted.

Installation Procedure

Important Note: Do not cut the BLACK tube when installing this system.

1. Shut off the water supply to the kitchen sink.

2. Find a convenient location for the purifier under the sink, taking into consideration ease of access and best use of cupboard space. Using self-tapping screws provided, attach the purifier to the cupboard wall in the desired location. Choose a location where water spillage will not cause damage and out of direct sunlight.

3. Connect the adaptor to the cold water line and install isolation valve, flow control valve and tube adaptor to allow the 1/4” O.D. plastic GREEN tubing to be connected.

4. Select location on kitchen sink to install faucet. Make sure there is adequate access under the bench top for the hoses. The faucet supplied with the system requires a ½” (12 mm) hole. Use a centre punch to locate the position to drill. Drill a pilot hole and gradually enlarge until you have the correct size hole. Connect BLUE tube to faucet.

5. To install faucet, place in order the small rubber washer, chrome washer and large rubber washer onto the threaded end of faucet. Insert the faucet into the hole in the sink. Slip the large plastic washer and lock washer onto threaded end of faucet and screw on nut. Tighten nut, making sure faucet is correctly positioned on top.
   Note: Reverse osmosis systems are unique in that they flush the impurities away. Therefore every RO systems has both pure PRODUCT water and dirty REJECT water. The ratio of Product to Reject is generally about one to two. The ratio can be adjusted to recover a higher ratio rate but the life of the membrane will be reduced. The Reject water is usually dispensed down the drain although it can be directed to the garden if desired. To be environmentally friendly, the Puretec RU system has a built in shut off valve so that when the storage tank is full it stops producing water.

6. Install the drain clamp by drilling a 4 mm hole in the waste pipe. Position the drain clamp above the trap. Connect 1/4” BLACK drain tube to drain clamp and tighten compression nut. Do not allow drain hose to protrude more than 10 mm into drain, making sure the holes in the drain and the clamp are exactly aligned. This can be done by inserting a thin Phillips screwdriver through them whilst tightening the clamp.

7. When connecting the green, red, blue and yellow tubes leave plenty of extra length so that the purifier can be repositioned during servicing without having to disconnect all the hoses.

8. Connect YELLOW tube to storage tank. Screw ball valve to tank outlet and ensure valve is open.

9. Once unit has been completely plumbed it will need to be actuated. To do this ensure isolation valve is off and faucet is open. Gradually open isolation valve to begin water production. The first sign will be water running to drain. This is normal and then finally product water will begin coming out faucet. This may take several minutes. At this stage close faucet. This forces product water to fill up the storage tank. To check that water is still being produced, check water is running to drain. This should continue for several hours until tank is full. When tank is full, the pressure in the tank will overcome the inlet water pressure and the shut-off valve will activate, shutting off the inlet water. To check this, check if water is running to drain. Once tank is full, no water should run to drain. To flush system, allow tank to fill, open faucet outlet until water stops, close faucet and allow tank to fill. Check all connections for leaks.

10. Reverse osmosis systems produce water slowly, almost drop to drop. If the tank is empty to begin with, it will take the tank 3 to 4 hours to fill. Reverse osmosis systems product water slowly. Initially filling the tank will take 3 – 4 hours. Fill and empty twice before drinking water from the system. This is essential in order to flush away any sterilising solution in the membrane.

11. Check all connections are tightened properly. Check for leaks.

12. To dispense drinking water from the faucet, push and hold the handle down or push up for continuous operation.

13. When the unit is in place and the water lines are installed, the unit should be run for 4 hours before the purified water is used, on initial start up. The unit cannot be stored for more than 2 weeks without use, or damage to the membrane may occur. Please enquire if this is the case. For a period of non-use greater than 2 days, flush for 10 minutes before use. For non-use periods of more than 2 weeks, the cartridges may need replacing.

14. The sediment and chemical removal filters should be replaced every 6 months. The membrane should be replaced when water quality deteriorates or every 18 – 24 months, depending on incoming water quality.
    Use only genuine Puretec replacement cartridges and cartridges that are suitable for this appliance.

2. Fitting grips before it seals. Ensure tube is pushed in to tube stop.

3. Tube is secured in position.

4. DISCONNECTION PROCEDURE
   Push collet against body and slide tube out of fitting.

Use Guidelines

• Minimum operating pressure 300 kPa.

• Maximum pressure 600* kPa.

• Do not allow exposure to temperatures below 0 °C (protect from freezing).

• Maximum operating temperature 38 °C.

• Nominal flow rate 4 Lpm.

• This system must be installed according to local plumbing codes on the cold water line.

• Replacement Cartridges: See Cartridge Installation

• This system requires regular replacement of the filter cartridge to maintain proper operation.
  Varying chlorine, sediment, or organic substance levels may affect replacement frequency.

• Be sure to change the filter cartridges at least every 8,000 litres or 6 months which ever occurs first; or whenever you detect a change in taste, odour, or decrease in flow. 8,000 litres is approximately equal to using 20 litres daily for one year.
