4.12 Periodic Preventive Maintenance
Because of aging of elastomeric components and the desirability of checking
internal zones for possible accumulations of deposits not seen in routine main-
tenance, 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 Section 6 of this book for appropriate kit numbers.
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 per-
sonnel who are completely familiar with the entire contents of the equipment
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.
