There are two fittings on the Control Valve. One fitting is on the inlet side of the Valve and the other is in the center of the Valve. Each fitting comes from the factory with a black protective dirt plug. To remove the plug, press downward on the collet ring at the top of the fitting while pulling the plug upwards and out of the fitting.
Connect the blue color-coded tubing to the Control Valve’s center blue color-coded fitting. Simply press the tube into the fitting until it stops. Pull outwards to confirm tube is locked into the fitting. To remove the tube from the fitting, press downward on the collet ring at the top of the fitting while pulling the tube upwards and out of the fitting. Next, connect the red color-coded tube to the red color-coded fitting on the Valve.
