Puretec Customer Service

Thank you for purchasing the Puretec drinking water filter system. Your system is a proven performer manufactured from only quality materials and components and will give years of ‘spring fresh’ water free of impurities if maintained properly. The Puretec RO series system cartridges need replacing regularly to maintain optimum performance. This is a simple procedure when following instructions. For cartridge, replacements contact your nearest Puretec stockist. The system is designed for metropolitan supply water but can be used in other situations. For other types of water supply please contact your local Puretec stockist or call our Puretec Customer Service Helpline prior to installing the tap.

Operation

The Puretec RO series system is designed to run economically for many years, dependent on the initial installation and periodical maintenance.
Flush systems for 10 minutes after any period of non-use for more than 2 days. For a period of non-use of 2 weeks or more, it may be necessary to replace the cartridge.   Chrome Plated Surface – should only be cleaned with liquid detergent or soap and water. Under no circumstance should any abrasive or acid-based cleaning agents be used. 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 rain 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 SHOULD BE COMPLETED BY QUALIFIED TRADESPEOPLE. FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED WARRANTY COVERAGE.

Cartridge Replacement

To maintain the high quality of the purified water, the cartridge needs to change every 6 months (dependent on water quality and usage).
When replacing the cartridge, ensure you reset the LED reminder light by removing/replacing the battery from the rubber seat. Please refer to page 8 for a detailed diagram. Order PX051 & CB101 for replacement cartridges and RET1812-75 for replacement membrane to suit your CO-RO270 or CO-RO270P Series system.
System Installation
This system should be connected to 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 Australian Standards in full compliance with the relevant laws. Further plumbing connections will be required to connect the system to the water supply, an isolation valve is recommended (not included). The installation of a flush valve on the pure water outlet line prior to the foodservice equipment is required (not included). Caution: This product must be installed in accordance with local plumbing regulations by a licensed plumber.
Installation Requirements
1 13 mm (½”) cold water line.
2 Supply pressure: 300 – 520 a.
3 Supply temperature 0° – 30 °C (protect from freezing).
4 Suitable location.
To provide supply water to the RO system inlet, a feed supply fitting is required or install pipe fittings as needed. The feed water valve should be located as close to the system as possible. USE COLD POTABLE WATER SUPPLY ONLY. Softened water is preferred as it will extend the life of the RO membrane.
Cartridge Installation
1. Unscrew filter housings using the spanner wrench (supplied). Membrane housing caps can be unscrewed by hand.
2. Install new cartridges and replace housings, screwing them up HAND TIGHT ONLY. PX051 filter is on the inlet side and CB101 on the outlet side. Install RET1812 on membrane housing. See Figure 1 (page 6).
NOTE: When removing the membrane from the packaging, only remove the outer shrinkwrap packaging, DO NOT remove any other packaging from the membrane.

Installation Procedure

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

1. Find a convenient location for the filter system under the sink taking into consideration ease of access and best use of cupboard space. Allow 30 mm clearance under the system for cartridge replacement. Using self-tapping screws provided, attach the filter system to the cupboard wall in the desired location. Choose a location where water spillage will not cause damage and is out of direct sunlight.
2. Isolate water supply. Uninstall the connections on the cold water line and connect to the GREEN tubing.
3. Connect the BLUE tube (pure water outlet) to the flush valve (not included) and connect the flush valve to foodservice equipment.
4. Install the drain clamp by drilling a 4 mm hole in the waste pipe. Position the drain clamp above the trap. Connect ¼” (BLACK) drain tube to drain clamp and tighten the compression nut. Do not allow the drain tube to protrude more than 10 mm into the 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.
5. When connecting the green, red, blue, and yellow tubes leave plenty of extra lengths so that the purifier can be repositioned during servicing without having to disconnect all the tubes.
6. Before installing the pressure tank the system will need to be flushed. Allow the system to fill with water, (CO-RO270P models: switch on the booster pump) and continue to flush for 5 minutes. Note: Place the yellow tube in a bucket/drain to collect the flushed water.
7.  Once the system is flushed, turn off the pump and isolate the water supply. Screw the Ball Valve to the tank outlet and ensure the valve is open. Connect YELLOW tube to Storage Tank.
8. Open up the water supply, (CO-RO270P models: turn on the booster pump) and allow the storage tank 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 the tank is full. When the 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 the tank is full no water should run to drain. To flush the system, allow the tank to fill, open the faucet outlet until water stops, close the faucet, and allow the tank to fill.
9. Reverse osmosis systems produce water slowly. To begin with, the tank will take 3 to 4 hours to fill. Fill and empty the tank twice before drinking water from the system. This is essential before drinking any water to flush away sterilizing solution used in the membrane.
10. Check all connections are tightened properly. Check for leaks.
11. 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. After a period of non-use greater than 2 days, flush for 10 minutes before use. For non-use greater than 2 weeks, the cartridges may need replacing.
12. 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. For best performance use only genuine Puretec replacement cartridges and cartridges that are suitable for this system.

NOTE: When removing the membrane from the packaging, only remove the outer shrinkwrap packaging, DO NOT remove any other packaging from the membrane.
