Q. Why should a customer be discouraged from buying a V6without a tee and installing it in his own tees?
A. Two reasons: One, thecustomer will frequently tighten the body in the tee one turn toomany, resulting in the vane hitting the tee. This bends the vaneand it can jam up even after the switch is backed out one turn toits proper position. Two, there is also a wide variation in teedimensions between manufacturers which aggravates the problem.
