9. Turn the air supply switch of the EN-46999 to the ON position. With the air supply connected to the manifold assembly and the solenoid/valves in
the closed position, a limited amount of air will exit each of the bleed holes (3) and outlet ports (1, 2) of the manifold.
10. Important: The manifold must be tested in the proper position to ensure the solenoid/valves operate as designed.
Position the manifold assembly onto a bench at a 45 degree angle in order to test solenoid/valves 1 and 4.
11. Depress button number 1 on the tool to activate solenoid/valve 1. With button 1 depressed, the solenoid/valve (1) should open, allowing an
increased amount of air to exit the outlet ports (2) of the manifold.
12. Depress button number 4 on the tool to activate solenoid/valve 4. With button 4 depressed, the solenoid/valve (4) should open, allowing an
increased amount of air to exit the outlet ports (3) of the manifold.
