Connect piping/fittings using the recommended torque while holding the product tightly.
Looseness or faulty sealing will occur if tightening torque is insufficient, while thread damage will result
if the torque is excessive. Furthermore, if the side with the female threads is not held while tightening,
excessive force will be applied directly to piping brackets, etc. causing damage or other problems.

Do not apply any additional twisting, or bending moments except for the weight of the filter

Provide separate support for external piping, as damage may otherwise occur.

Non-flexible piping materials such as steel piping will be subject to excessive moment load
and vibration from the piping side, so use a flexible tube for intermediate connections.

Preparation before piping
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove
chips, cutting oil and other debris from inside the pipe.

Wrapping of sealant tape
When screwing piping or fittings into ports, ensure that metal chips from the pipe threads or sealing
material do not enter the piping.
Furthermore, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.
