Puretec Customer Service
Thank you for purchasing 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 Help line 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 more than 2 days. For a period of
non-use of 2 weeks or more, it may be necessary to replace 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 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 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 changing every 6 months
(dependent on water quality and usage).
When replacing 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 a 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 food service 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 kPa.
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.

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 compression nut. Do not allow
drain tube 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.
