Chapter 9 — Control Cavity
Removing the Control Housing
1.
Remove the top housing and level sensors as described in
Chapter 7 – Top Housing
and
Chapter 8 – Level Sensor
, respectively.
2.
Loosen and remove the air release plug using a 3/16-inch hex key.
3.
Install the control cavity air test fitting and use a regulated low pressure line or hand
pump to pressurize the control cavity to 5 psi.
4.
Use soapy water to test for leaks around the O-ring joint and compression nut.
Submerging the assembly may aid with finding leaks. Clearing trapped air may take
several minutes.
5.
Use a 1/2-inch deep-well socket and a 1/2-inch wrench to remove the three retaining
bolts from the control housing.
6.
Break the seal and lift the control housing using two pry bars. Pry upward until the
control housing is free, taking caution not to pull the wires apart from the control
bracket assembly.
