Disassembly
1. Disconnect pilot supply filter regulator and remove
it from the line.
2. Remove bolts, washers and nuts from body and
separate upper and lower covers from the body.
When separating the covers from the body, be
aware of loose components.
3. Remove and inspect O-ring for damage or
wear,and replace if necessary. Lightly lubricate the
O-ring before placing it back in the filter cover.
4. Clean screens. Replace filter pad.
5. Inspect diaphragm for damage or wear and
replace if necessary. Check the seating surface
of the screw unit for erosion, scratches, spurs or
other damage and replace if necessary.
6. Unscrew and remove the regulator seat. Inspect
O-ring for damage or wear and replace if
necessary. Lightly lubricate the O-ring and place it
on the regulator seat.
7. Pull pad holder unit out of the body. Inspect the
seat for damage, replace if necessary.
8. Set the filter net on the spring and insert the
regulator seat. Tighten the regulator seat until
it stops.
9. Lightly lubricate the outer and inner rims of the
diaphragm. Place the diaphragm assembly on top
of the regulator seat. The screw unit will slide into
regulator seat. Use care to avoid damage to parts
when reassembling.
10. Set the spring on top of the nut.
11. Align the regulator cover over the body with the
sense port opposite the pilot supply port.
12. Place the filter pad and screens, one on each side
of the filter pad, on the filter cover.
13. Pick up the body and place it on the filter cover
with the inlet port aligned vertically with the
sense port.
14. Insert bolts. Place washers and nuts on the end of
the bolts. Tighten the nuts.

Spare Part Selection
Level Switch - Gauge - Proportional
Valve Code Selection
To select the proper code for level switch, gauge and
proportional valve please check the Type Dosaodor-D
identification label the values of:
• Maximum operate pressure
• Odorant flow range
These two values allow you to identify the correct raw
codes in the codes table.
For example with Odorant flow range = 0.26 gal/h and
Maximum operate pressure = 200 psi the correct Level
switch code is highlighted in gray.
Please use the following complete codes table.
