Tubing size (in. (mm))

When bending the tubes, use a bending

radius that is at least 4 times the outer

diameter of the tubes.

In addition, take sufficient care to avoid

crushing or damaging the tubes when

bending them.

*1: For the solenoid valve kits, use type 160 with parallel specifications. Branch the tubing before and after the solenoid valve kits.
