2. When using a T-tee branch tube (provided by installer) (only with L3 at 2 m or less), the main tubing must be either level

The openings can be set at any angle when the main tubing is vertical, but be sure to curve a portion of the connected
tubing upward. Always close weld the end point of the T-tee tubing. In addition, pay special attention to the insertion

standard T-tees.
3. Do not use commercially available Y-shape joints (
