11. Inspect the orice (key 4) of the regulator by
unscrewing the inlet adaptor (key 3) and
removing it from the coupling. Unscrew the
orice. Check O-ring (key 23) also.
Reassembly
Coat external threads with a good grade of pipe
compound when reassembling the regulator.
1. Place the O-ring on the inlet adaptor and screw
in the orice.
2. Reassemble the pusher post, bafe and lever
unit. Put the unit into the body and connect the
lever to the stem. Place an O-ring on the lever
pin and screw it into the body and through
the lever.
3. Set the diaphragms on the pusher post. The
composition diaphragm goes on rst, with the
metal diaphragm placed over it. (In Type 1305D
regulators, both diaphragms are metal).
4. Set the diaphragm head over the diaphragms
and screw the hex nut onto the pusher post.
5. Put the spring and upper spring seat onto the
diaphragm head. Set the spring case on the
body. Insert the machine screws, tightening
them nger-tight only.
6. Screw the disk holder into the stem.
7. Slide the regulator into the inlet adaptor and
tighten the union nut.
8. To ensure proper slack in the diaphragm,
apply spring compression by turning the
adjusting screw clockwise. Finish tightening the
machine screws.
9. Connect the inlet and outlet piping to the
body connections.
