3 Required Tools
For installation, you need the following tools and materials：
• Metal wrench 13mm / 14mm / 17mm
• Scissors
• Power Drill
• Drill Bits 6mm / 12mm
•PTFE Tape
Caution
This system is equipped with quick fitting connectors. With the quick fitting connectors, you can easily and safely
connect the PE tubes. Plug the tubes into the counterparts until you feel a click. When click occurs, then the tube is
correctly fastened in the anchoring device.
If you want to remove the tube again, you must, at first, remove the
retaining clip.
And then, at the junction, you will see a small white plastic ring. Press the plastic
ring evenly then pull out the tube.
If the mains water pressure is higher than 6 bars, one pressure- reducing device must be installed before the inlet port of
the Pura.
4 RO Installation
1
Open the lid of the Pura housing.
Remove the combo cartridge filter from the Pura.
The combo cartridge filter has been loaded into the Pura
for transportation.
2
There are two small black rubber seals
on one side of the membrane.
3
In the center of the Pura, you can see a circular slot
for the membrane.
4
Insert the side which has the two small black rubber
seals into the circular slot.
Open the lid

5 Combo Cartridge Filter Usage
1
Remove the film wrapping from the filter before use.
And then put the combo cartridge filter back into the Pura
housing.
2
Make sure that the O-ring on the edge of the lip is
properly seated and then evenly close the lid by hand. And
then use the wrench to tighten the lid gently.
Caution
There are 6 semi-circular bumps on the top of
the lid of the Pura, and there are 6 rectangular
bumps on the wrench.
Match with each other properly before
opening or closing the lid.
6 Pressurised Tank
Choose the right location for the tank. The tank must be placed upright. Keep it away from direct heat sources
(eg boilers).
Please follow the steps as below:
•Swivelling the ball valve onto the tank threaded fitting.
•Please tighten the ball valve properly to avoid water
leakage

7 Tap Installation
Choose the appropriate installation location before starting.
The tap should be located where it is easy to use.
To install the tap on the kitchen counter, you need to drill a 12mm hole in the kitchen counter or
the corner of the stainless steel sink. Seek professional advice before drilling granite.
Follow these steps:
1
Drill a 12mm hole in the worktop or stainless steel sink.
Insert the threaded rod of the tap through
the metal plate first.
2
Insert the threaded rod through the hole on the worktop/sink.
3
Screw the nut tightly on the threaded rod of the tap.
4
Connect the ⅜” union connector to the threaded rod of the tap
tightly.

8 Connecting The Water Inlet
The integrated adaptor comes with mains water supply and
adaptor connections.
Turn off the mains water by closing the angle valve under the
sink.
Unscrew the cold water pipe and then connect the integrated
adaptor to the angle valve.
Connect back the cold water pipe onto the other side
of the integrated valve.
Now unscrew the nut from the plug valve of the adaptor and
then insert the ¼” blue tube into the protruding ring.
Then screw the nut back to the plug valve.

•Drill a 6mm hole on the sink drain pipe.
•Seal foam rubber around the hole.
•Fix together the two clamp rings (tighten with two screws).
•Insert the nut on the blue tube.
•Insert the blue tube into the port of the clamp.
•Screw the nut tightly on the clamp ring.
Choose the best installation location before installation and, usually, the best installation location is in the
upper area of the sink drain pipe. Do not install in the corner area of the pipe!
Please follow the steps below:

10 Connecting The Ports
On the black base of the Pura, you will see three ports. Connecting steps are as follows:
1
Inlet Port (left side)
This is the inlet port of the Pura.
Connect it to the integrated adapter with ¼” blue tube.
Drain Port (right side)
This is the drainage port of the Pura.
Plug the ¼” yellow tube into this port.
3
Pure Port (middle）
This is to be connected to the pressurised tank.
Connect it to the tank’s ball valve with
¼” blue tube.
4
Pure Port (front)
This port is for connecting to post-carbon (w/stem adapter) or
to tap directly (change the stem adapter to female connector)
