1.Before using the water purifier fittings, please check them carefully. If there are distorted or broken ones, then they are likely to lead the leaking of the water purifier machines, or some other potential problems of future use process.

2. The quick connectors are connected with the purified water directly, the raw materials must be food rank and nontoxic, to avoid secondary pollution.

3. During installing the RO quick connect fittings, please do not disassemble or modify the individual part, which may cause leak or connection failure.

4. Do not over-stress the quick connectors by rotation, twist, bending, shock, fatigue, or other excess force, which may damage the connectors and cause leak or connection failure.

5. Do not use the quick connect fittings near the fire, or where ambient temperature or fluid temperature may exceed 80 ℃, as the materials of the quick connectors are plastic, which will deform in high temperature for a long time.

6. Do not install the quick connectors outdoor, the sunshine will age and damage the plastic and then lead leaking.

7. Do not use pipe glue or other liquid thread sealer, use only Teflon tapes to seal threaded connections.

8. Do not press the collects toward the main body unless attempting to separate tube from the water filter connection fittings in a unpressurized line. The use of blue clip is advised to restrict inadvertent disassembly of connections.

9. Before making tube connection, verify that the end of pipe has been cut square and there are no scratches on the tube OD within 30 mm of the end.
