(Lubricate the silicone hoses with WD40.) Install the short side of the 90° silicone hose to the 2” side of the tubing junction, then connect the aluminum tubing and the 2” straight silicone hose using the four 46-64 clamps. Lightly tighten the clamps. (Photo shows hose configuration and placement, ignore that the bypass valve is already on but note placement.)
