4.12.2 Removal of Injector Plug (2" Bellofram Type Injector, Dwg. 25.052.001.046)
CAUTION: If the injector plug is to be removed for cleaning or replacement,
it is essential that the plug rod (6) be held with a wrench so it cannot rotate
when the plug is unscrewed. Rotation of the plug rod will cause damage to
the bellofram (16).
4.12.3 Replacement of Bellofram (See Dwg. 25.052.001.046)
Damage to the bellofram (16) is indicated by a continuous flow of water from
the injector shut-off valve drain when the valve is in the OFF position or by
failure of the injector to operate when the valve is in the ON position.
To replace the bellofram, proceed as follows:
a. Remove the adjusting screw nut (19) with the adjusting screw (21), lock
nut (20), and spring (50).
b. Remove the connecting tube (26).
c. Remove the two 1/2-inch cap bolts (49) and lower the entire lower portion
of the injector, including the plug rod (6) and plug (4).
d. Remove the old bellofram and assemble the new one on the plug rod (16).
e. Locate the bellofram on the backing cup (15).
f. Reassemble the injector.
