Maintenance
Precautions
DANGER:
Electrical hazard sufficient to kill. Always disconnect and lock out the power before you
service the unit.
WARNING:
• This manual clearly identifies accepted methods for disassembling units. These
methods must be adhered to. Trapped liquid can rapidly expand and result in a
violent explosion and injury. Never apply heat to impellers, propellers, or their
retaining devices to aid in their removal.
• Make sure that each pump and the package are isolated from the system and that
pressure is relieved before you disassemble the pump, remove plugs, open vent or
drain valves, or disconnect the package piping.
• Always disconnect and lock out power to the package and the driver before you
perform any installation or maintenance tasks. Failure to disconnect and lock out
driver power will result in serious physical injury.
• Crush hazard. The unit and the components can be heavy. Use proper lifting methods
and wear steel-toed shoes at all times.
• Rotating shaft. Make sure that the packing adjustment is performed by qualified
personnel only.
CAUTION:
Equipment damage hazard. Silt buildup is a sign of problems with the wet well and/or
intake screen. Failure to follow these instructions indicates a potentially hazardous
situation, which, if not avoided, may result in property damage.
Monthly maintenance
Control panel checks
• Verify that all of the operator interface keys and LEDS operate properly (see controller
manual).
• Review the station operation, fault history, and data log for station operation.
• Verify that all surge devices are visually sound, where applicable.
• Check the surge device for the station which is mounted on the back of the
control panel.
• Black soot on or around the device indicates that it has taken a surge and needs
to be replaced.
