Panel
Installation

Electrical Connections:

The contractor must conform
to the latest requirements of the
National Electrical Code. All
conduit and ca bles shall be in
accordance with NEC code NFPA
#70. To maintain UL type 4X
and CSA ENCL 4 rating, use UL
type 4 and CSA weatherproof
con duit hubs when connecting to
this enclosure. Prior to conducting
any in stal la tion, repair or service
with re gard to the control panel,
refer to the schematic ap pro pri ate
for that panel. The sche mat ic will
provide guidance with regard to
the terminal block con nec tions.

CAUTION: Nonmetallic
enclosures do not provide
grounding conduit con nec tions.
Use grounding bush ing and
jumper wires.

Make the Following Electrical
Con nec tions:

a. Connect the pump leads to

the control panel. When
connecting the pump leads
it is very critical that the
prop er sequence be main tained.
On single phase pumps, the
color coded pump leads black,
white, red, must be connected
to the appropriate terminals
as directed by the control
schematic.

b. Connect the pump heat sensor

and seal failure leads (if
available on the pump) to the
appropriate ter mi nal blocks
in the control panel. If the
heat sensor lead from the
pump is wired as indicated,
re move jumpers as defined by
the sche mat ic.

c. Connect all the float control

leads to the appropriate panel
terminal blocks. Con trac­tor must be very careful in
locating the floats at the proper
elevations. The maximum
distance from the control panel
and the floats is the lesser
of l00 feet, or the maximum
distance recommended for
the pump.

d. Before connecting power to

the control panel, make sure
all the control switches (e.g.
H-O-A switch) and protective
devices (e.g. breakers) are in
the Off position. Now connect
power to the circuit breaker as
directed by the schematic.

e. Power must be the correct

voltage for the pump model.
Power must have neutral
to supply 120 volts to the
control circuit.

f. Control panel must be grounded

properly per NEC and/or local
codes. To facilitate this, a
ground lug is provided on the
control panel.

Panel
Operations

WARNING: Before handling
these Hydromatic 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.

Check List:

1. Check junction box for
moisture.

2. Check wiring of pump black,
white, red power wires.

3. Check wiring of heat sensor
and seal failure wires if
supplie

4. Energize control panel. (Turn
on power to panel.)

5. Check overload relay and
verify reset mode (if
overload is supplied).

6. WARNING! Live voltage
can kill! Check voltage to
the panel and to the con trol
circuit using a voltmeter.

7. Check float operation and
response to control panel
to the float operation. For
sequence of operation, refer
to design specification.

8. Check full load current with
amp probe and compare it
with the nameplate rat ing.
(Clamp amp probe around
black pump wire.)

9. With pump running, check
discharge to verify the pump
is running. Check for flow.

10.Check operation of start relay,
per procedure in Item #3 on
page 4.

11. Make sure H-O-A switch is
left in the Auto position after
start-up is com plet ed.

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”.

Panel
Maintenance

WARNING: Before handling
these Hydromatic 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.

1. Pump does not run in
Hand position.

a. Check pump circuit breaker

and control fuse for trip ping
or blown condition.

b. Check incoming power

voltage and control
circuit voltage.

c. Check overload relay to see

if it is tripped. Reset relay
if tripped.

d. With the power off, check

motor heat sensor continuity.

e. Check wiring of pump to

control panel. It should
agree with the schematic.

f. Check contactor coil

resistance. It should be 50
to 200 ohms.

2. Pump does not run in
Auto position.

a. Check items (a.) through

(d.) per Item #1.

b. Floats may be miswired to

control panel. Check float
type (N.O. or N.C.) and
hook up by referring to the
schematic. If the start and
stop floats are hooked in
reverse, pump will short
cycle and will not pump the
level down.

c. Is the water level in the

system high enough to
activate floats?

d1. With the power off, remove

Off float and On float
wires and replace with
two jumpers made from
insulated wire.

d2.Turn power on (with H-O-A

switch in Auto position). If
pump runs, the prob lem is
in one of the floats.

d3.If the problem is in a float,

turn power off, remove
jumper and reconnect the
upper float. Turn power on
and see if pump will run in
Auto. This will help identify
which float is the problem.
Turn power off before
removing any jumper or
reconnecting any float.

3. Pump runs, but run light
does not energize.

a. Remove light bulb and

check with ohmmeter.

b. Check wiring for run light

in panel.

4. Pump runs but does not
pump down the wet well.

a. Impeller may be dragging

in volute due to solids.
High am per age draw would
identify this.

b. Refer to the pump manual

for other possibilities such
as closed discharge gate
valve, etc.

5.

Severe humming/chattering of
contactors and control relays.

a. There may be low voltage.

Check voltage to the panel
and to the control circuit
using a voltmeter. This
low voltage condition may
even cause se vere chattering
and burn-out of relays.
Contactors require a
minimum of 85% of full
