5.9.2 Product Regulator Cleaning or Rebuilding
Clean or rebuild the product regulator if the regulator cannot be adjusted for
lockout.
1.
Set the unit’s ON/OFF switch to the ON position and disconnect the power
cord.
2.
Remove the right-side panels and back panels.
3.
Use large pliers to unscrew the bonnet of the product regulator, which
contains a large spring.
Adjust the product regulator fully counter-clockwise to unload the
spring. This makes disassembly and reassembly easier.

Remove the diaphragm. (Clean or replace it.)
5.
Using a Phillips-head screwdriver, unscrew the diaphragm stem guide
located in the center of the regulator body to gain access to the seat.
6.
Remove the seat. Be careful not to lose the spring located behind the seat.
7.
Clean or replace the seat.
8.
With the spring behind the seat, screw the diaphragm stem guide back into
the body of the regulator. (Do not over tighten.)
9.
Install a clean or replacement diaphragm.
10.
Put the large spring and slip ring into the bonnet and screw the bonnet onto
the regulator body.
11.
Reset the product regulator as described in Section 5.9.1
