d. Before connecting power to the control panel,
make sure all con trol switches (e.g. H-O-A switch)
and protective devices (e.g. breakers) are in the
Off po si tion. Now connect power to the terminal
block or the circuit break er as directed by the
sche mat ic.
e. Control panel must be grounded properly per
NEC and/or local codes. To facilitate this, a
ground lug is provided on the control panel.

START-UP OPERATION:

1. Check junction box for moisture. Moisture may
cause chattering of relays/contactors.
2. If pump is single phase with start capacitor,
start relay and run capacitor in panel. Check
that pump main and start winding pow er wires
are con nected to pan el correct ly. Refer to
your pump owner's manual for lead colors.
3. WARNING: Live voltage can kill! Check
incoming power volt age to make sure that it is
correct for panel and pump model.
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 transformer 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 operation
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.
Pump Start-Up: Refer to pump Installation and
Service Manual.

PUMP MAINTENANCE:

WARNING: Before handling these pumps
and controls, always disconnect the power 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 one cy cle. 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. For 1 phase panels with start circuit, about 5
seconds after the pump starts check the voltage
from terminal 1 to terminal 2 on the start relay to
be sure that the relay has operated. The voltage
from terminal 1 to terminal 2 on the start relay
must exceed 10 VAC. For some pumps the
voltage may exceed 400 VAC. If after 5 seconds
the voltage from terminal 1 to terminal 2 on the
start relay does not exceed 10 VAC stop the
pump as damage to the start capacitor may
occur in about 15 seconds.
If the start relay is not operating check the pump
and the system voltage to be sure that they
match. Check the power wiring to ensure that
the pump is connected properly. Start the pump
once more and check that the voltage from the
terminal for the black wire to the white wire is
within system tolerance. Call for help if you
cannot resolve the problem.
8. Check junction boxes for moisture. Moisture may
cause chattering of relays and contactors.
