4.12 Periodic Preventive Maintenance
Because of aging of elastomeric components and the desirability of check-
ing internal zones for possible accumulations of deposits not seen in rou-
tine maintenance, it is recommended that, at one-year intervals, each of the
principal components of the system be completely disassembled. Before
starting the work, ensure that the appropriate preventive maintenance kits
are on hand.
NOTE: If the gas feeder is used seasonally or with a long-term shut-
down, the preventive maintenance should be performed prior to
startup.
Refer to the tabulated listing below and Section 6 of this book for appro-
priate kit numbers.
Disassembly and reassembly instructions necessary to install the mainte-
nance kit parts are included in the kit(s).
Servicing of USF/W&T equipment, including installation of parts from
maintenance kits, should be restricted to trained, authorized personnel
who are completely familiar with the entire contents of the equipment
instruction book. The USF/W&T sales office or the dealer from whom you
purchased the equipment can provide the preventive maintenance kits or
overhaul service.

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 re-
placement, 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).
