One. How to connect the water pipe to the water filter.
1、 Prepare all the tools needed for installing the water pipe for the water filter. Distinguish between the quick-connect fittings, one with a blue card and one without a blue card. The operation is basically the same. When removing the pipe, for the fittings with the blue card, first remove the blue card. Hold the fitting with one hand and press the retaining clip at the top of the fitting with your other hand, while using your other hand to grip the PE pipe and pull outwards with some force, which can remove it. For the fittings without the blue card, you can ignore this step.

2. Hold the connector in one hand and the pipe in the other. Do not need to press the retaining clip again; simply insert the pipe with a slight force. once you feel some resistance, the pipe is properly installed.
3. For those with blue cards, please affix them. Those without blue cards do not need to take any action.
