SECTION 4.0: Plant Troubleshooting
Guide
4.1:
The Hydro-Action
®
AP Series plant has
proven to be very effective and reliable in the
treatment of domestic wastewater. The
problems outlined here occur only in a very
small percent of total installations. They can all
be corrected and most can be prevented.
4.2: When the owner/user calls, ask him or her
to describe the problem in detail and determine
the plant age and service history from your
records. This information is then used in
preparation for the service call.
4.3: First perform a routine service call as
described in section 1.0, Plant Routine
Inspection and Service Instructions.
4.4: If routine servicing does not solve the
problem, go through the steps listed below.
4.5: Verify model number of plant and
OPS ®
with those in records. If this is a new
installation, you should verify that the plant and
all its components were installed correctly and
in accordance with manufacturers and
regulatory agency requirements. See
Hydro-
Action
®
AP Series Installation Manual,
available from Hydro-Action
®
.
4.5.1:
Inspect plant to verify that the Hydro-
Action
®
plant is installed properly and is not
damaged. Plant should be level and internal
components should be in proper place and
correct working order.
4.5.2: Check to see that effluent disposal
method is allowing for proper level to be
maintained in plant. High level in plant can
adversely affect performance.
4.6: After confirming that Hydro-Action
®
plant
is installed properly and is not damaged, check
the operational and maintenance conditions of
the plant to determine if it is performing
correctly. To do this run a sludge volume test as
described in section 1.0. Compare your findings
with the conditions given in the
Hydro-Action
®
Plant Condition Chart, section 4.12. Follow the
recommended actions required to return the
plant to its proper operating conditions.
4.7: The alarms supplied with this wastewater
treatment plant provide the owner with a
secure, reliable and economical means of
notification for most malfunctions of the plant
that would lead to producing an unsatisfactory
effluent. These alarms include notification for
problems of air pump failure, aeration piping
malfunctions, and high water level. These
alarms need to be inspected and tested during
each plant operation and maintenance site visit.
If an optional remote alarm has been installed,
it should also be inspected and tested during
each site visit.
4.8: To gain access to the electrical controls
and air pump, remove the security screws
holding the
OPS
® enclosure to the base.
4.9:
The switch indicated “normal/silence” on all
OPS
® models is used to test the alarms, silence
an alarm condition, or is left in the normal on
position. The normal position of the mode is for
normal operation of the plant and silence is a
mode that will disrupt the audible alarm. Move
the switch to the left and hold to test the alarm.
You should see and hear the visible and
audible alarms when this mode is selected. The
OPS
® switch will reset itself automatically.
4.10: If the audible and visual alarms on the
outside face of the Hydro-Action
®
OPS
®
enclosure are indicated the problem might be
failure in power supply or air pump, or an
electrical short in the line between electrical
controls and air pump. See Appendix 2 & 5 for
electrical schematics and pump manuals.
4.11: The AP-Series plant is equipped with a
high-level float switch and alarm. If the system
also includes a pump/holding tank to remove
effluent, the
Hydro-Action
®
electrical controls
may include a second high-level alarm. If the
owner reports high-level alarm light on, service
technician should be sent to correct the
problem. A malfunctioning water pump or level
float or a plugged discharge could cause the
high level conditions. A malfunctioning high-
level sensor float could give a false high-level
alarm. This problem left uncorrected will lead to
system failure and improper wastewater
treatment and therefore requires immediate
attention.
