To install the switch, follow these steps:
1. Apply pipe sealant with Teflon ® (Loctite ® No.
59241 or equivalent) to the threads of the switch.
2. Install the switch into the tapped hole in the
breather cover. See Figure 6-8.
3. Torque the switch to 4.5 N·m (40 in. lb.).
Testing
Compressed air, a pressure regulator, pressure gauge
and a continuity tester are required to test the switch.
1. Connect the continuity tester across the blade
terminal and the metal case of the switch. With
0 psi pressure applied to the switch, the tester
should indicate continuity (switch closed).
2. Gradually increase the pressure to the switch. As
the pressure increases through the range of
3.0/5.0 psi the tester should indicate a change to
no continuity (switch open). The switch should
remain open as the pressure is increased to 90 psi
maximum.
3. Gradually decrease the pressure through the
range of 3.0/5.0 psi The tester should indicate a
change to continuity (switch closed) down to
0 psi.
4. Replace the switch if it does not operate as
specified.
