4.7 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 routine
maintenance, it is recommended that at one-year intervals, each of the prin-
cipal components of the system be completely disassembled. Before starting
the work, ensure that the recommended spare parts are on hand. Refer to
Section 6 - Preventive Maintenance Kits and Spare Parts List for appropriate
maintenance kit numbers.
NOTE: If the gas feeder is used seasonally or after a long-term shutdown, the
preventive maintenance should be performed prior to startup.
Disassembly and reassembly instructions necessary to install the maintenance
kit parts are included in the kit(s).
Servicing of Evoqua Water Technologies 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 equip-
ment instruction book. The Evoqua Water Technologies sales office or the
dealer from whom you purchased the equipment can provide the preventive
maintenance kits or overhaul service.
