10* Gasket, neoprene, for all series 1C3286 03012
11* Sealing Washer (not shown) Use w/2 psi (0.14 bar)
pressure-tested case & cover (2 req’d) 1J1869 99012
Note
Key 13 is used as both a supply gauge and an
output gauge on units without a process pres-
sure gauge. A quantity of 2 is required for these
units. On units with a process pressure gauge
(key 106), key 13 is used for the output gauge. A
quantity of 1 is required for these units.
Use key 14 for supply pressure indication when
a process pressure gauge is installed. Key 14
installs on the supply pressure regulator.
