4. Energize control panel. (Turn
on power to panel.)
5. Check overload relay and
verify reset mode (if overload
is sup plied).
6. WARNING! Live voltage
can kill! Check voltage to the
panel and at secondary of
control trans form er using a
voltmeter. If no transformer is
supplied, check volt age at the
circuit breakers.
7. With H-O-A switch in hand,
check dis charge to ver i fy the
pump is run ning. Check for
flow. On three phase power,
check to see if each pump
has prop er ro ta tion. Wrong
ro ta tion will give low flow.
8. Check full load current with
amp probe and compare it
with the name plate rat ing. On
three phase pumps, check all
three phases. On single phase
pumps, check black pump lead.
9. Check operation of start relay,
if supplied on single phase
panels, per procedure in Item
#7 of Maintenance Instructions.
10. With H-O-A switch in Auto,
check float op er a tion and
response to control panel to
the float operation. For
sequence of op er a tion, refer to
design specification.
11. Make sure H-O-A switch is left
in the Auto position after
start-up is completed.
12. Make sure all conduits from
wet well to panel are sealed
below panel. Septic gases
will damage components in
panel.
Pump Start-Up:
Refer to pump Installation and
Service Manual.
WARNING: Before handling
these pumps and controls,
always dis con nect the pow-
er first. Do not smoke or use
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic sump.
The maintenance schedule
will vary with operating and
environmental con di tions. It will
also vary with the specific type of
control supplied. The list herein is
a guide only.
1. Exercise breaker through
two cy cles. Be careful not to
overexercise as the break-
er is not a switch ing device.
Excessive operations tend
to affect the trip curve of
the breaker.
2. Check contactors and relays
for excessive humming. This
can be accomplished by
turning pumps on and off
in the Hand mode with the
H-O-A switch.
3. Check pump run light(s) by
run ning pump(s) in Hand
mode. Check bulb(s) in any
other light(s).
4. With the power off, check
con ti nu ity of all control fuses.
5. Check voltage at primary
and sec ond ary of control
transformer.
6. Check the pump full load
amps.
7. Check the start relay by
using an amp probe around
the red wire (start wind ing).
Amp probe should display a
very brisk action from zero
to locked rotor and back to
operating load. This action
occurs on pump start, and
the action must show no lazy
movement.
8. Check junction boxes for
moisture. Moisture may
cause chattering of relays
and contactors.
9. Check for moisture inside
control panel enclosure.
Moisture can cause damage to
electrical com ponents. Check
door gasket for prop er seal.
10. Check labels to verify they
have not been damaged.
11. Lubricate enclosure hinges.
12. Pull floats and check for
proper operation and ensure
there is no foreign buildup
on them.
Spare Parts List:
The following is a list of
recommended spare parts.
However, conditions of ser vice
vary significantly and a general
list may not in its entirety be
applicable to a given installation.
The user should ex er cise judgment
in defining specific require ments
based on this guide.
1. Fuses for control transformer
primary and secondary.
2. Contactor.
3. Bulbs for any light requiring
a bulb.
4. Control transformer.
5. Alternator relay or duplex
alternator board, whichever is
required.
