CALIFORNIA PROPOSITION
65 WARNING:
This product and
related accessories contain
chemicals known to the
State of California to cause
cancer, birth defects or other
reproductive harm.
Pumps Not Operating or
in Storage:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting non-operational for 3
months or longer and prior to
electrical start-up.
Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 weeks or
longer and prior to electrical
start-up.
Seal Failure:
An electrode probe is installed in
the seal chamber so if any water
enters the chamber through the first
seal, the electrode will be energized
and a signal will be transmitted to
the sensing unit at ground surface
causing a red light to flash. The
electrode probe is installed in
all units, but the sensing unit is
supplied at extra cost and must
be ordered.
In operation the seal failure unit
indicates only that there is some
water in the seal chamber. The
pump will continue to operate
without damage, but the seal
should be checked immediately
after failure is indicated.
CAUTION: Failure to correct
leaking seal could result in water
entering motor chamber causing
shorting out of motor.
The sensing unit is recommended
on all installations as good
insurance against motor failure.
Seal Failure Probes:
All our hazardous location
submersible pumps have two
factory installed moisture detectors
(seal failure probes). They are in
a normally open series circuit, in
the seal chamber. Under normal
operating conditions, the circuit
remains open. If the lower seal
leaks and moisture enters this
chamber, the moisture would settle
to the bottom of the chamber and
will complete the circuit between
the moisture detectors.
This circuit must be connected
to a sensing unit and signaling
device. This is supplied in a
Hydromatic®built control panel.
NOTE: Failure to install such a
device negates all warranties
by Hydromatic.
Pump:
Power cable is supplied with
separate wire for ground. Be sure
green wire is connected to a good
ground such as water pipe or
ground stake.
Heat Sensors:
All motors have heat sensor units
embedded in the motor winding
to detect excessive heat. The
sensors automatically reset when
motor cools to safe temperature.
The sensors are connected in
series with the motor starter coil
so that the starter is tripped if heat
sensor opens. The motor starter is
equipped with overload heaters so
all normal overloads are protected
by the starter.
IMPORTANT: If Hydromatic
electrical starting equipment is
not supplied, the heat sensor
circuit must be connected in
series with the starter coil or
warranty is void.
Once sensor resets, the starter is to
be automatically reset for FM for
continued operation of the pump.
This circuitry is supplied in a
Hydromatic control panel.
Power Cords:
The power cord and heat sensor
seal failure cord are potted into
the connection box cap. The cords
must not be spliced.
NOTE: Each cable has a green
lead. This is the ground wire
and must be grounded properly
per NEC and/or local codes.
Cords should be inspected
for abnormal wear and
replaced accordingly.
Sump Level Control:
Sump level is controlled by
Hydromatic float switch controls.
The float is held in position in
the sump by a weight attached to
the power cord above the float.
The cord supports the float and
is adjusted for height from
the surface.
Typical duplex systems use three
controls: one set at turn-off, one
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate operation on each
successive cycle.
Two pumps operate together only
if sump level rises to the third or
override control. The override
control also brings on the second
pump in case of failure of the first

3
pump. Extra floats with appropri-
ate controls can be supplied for
alarm functions. Triplex systems
use four controls: one set at
turn-off, one set at turn-on for one
pump, one set at turn-on for two
pumps, and one set at turn-on for
three pumps. Pumps alternate each
successive cycle.
Three pumps operate together only
if sump level rises to the fourth
control (second override). This
control also brings on the third
pump in case of failure of either or
both of the first two pumps.
Alarm Controls:
The alarm level is usually set
above the override level so
the alarm will signal only if
the override level is exceeded.
However, some engineers prefer
to have the alarm level set below
the override level as it is possible
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reaching the alarm level. This is
particularly true in cases of low
inflow capacity.
Electrical Control Panel:
It is recommended that the
Hydromatic®control panel be used
with all pumps as proper starter
heaters and connections for heat
sensor wires are furnished.
The electrical equipment includes
a main circuit breaker for each
pump, a magnetic starter with
overload protection for each pump,
an H-O-A switch and run light for
each pump, an electric alternator
and a transformer to provide
appropriate control circuit
and alarms.
Overload Heaters:
If the Hydromatic electrical panel
is not used, starters with 3 leg
overload protection must be
supplied. The heaters must be
sized in accordance with the
nameplate amps on the motor
housing. The amp draw on these
submersible motors is slightly
higher than a corresponding
horsepower surface motor, so
heaters must be sized by the
nameplate rating.
IMPORTANT: Be sure the
heat sensor wires are connected
in series with the starter
coil circuit.
Pump
Installation
Installing Pump in Sump:
Before installing pump in sump,
lay it on side and turn impeller
manually. Impeller may be slightly
stuck due to factory test water,
so it must be broken loose with
small bar or screwdriver in edge
of vanes. The impeller should
turn freely.
Clean all trash and sticks
from sump and connect pump
to piping.
A check valve must be installed
on each pump. A gate or plug
valve in each pump discharge
line is also recommended. This
valve should be installed on the
discharge side of the check valve
so if necessary to service the
check valve, the line pressure can
be cut off. Single pump systems
are sometimes installed without a
check valve where it is desirable
to self-drain the discharge line to
prevent freezing. This can be done
only with short discharge lines,
otherwise water will return to the
sump and cause short cycling of
the pump.
Installing Sump Level Control
Float Controls:
In either simplex, duplex or triplex
systems the lower or turn-off
control is to be set to maintain a
minimum level in the sump. This
level shall be no more than 3-1/4"
from the top of the motor housing
down to the surface of the sewage.
The second or turn-on control is
set above the lower turn-off
control. The exact distance
between the two floats must be a
compromise between a frequent
pumping cycle (10 starts per hour
max.) to control septicity, solids
and a slower cycle for energy
economy. This distance should be
determined by the engineer or
consulting engineer depending on
the conditions of the application.
For installation of Hydromatic
supplied level controls, refer to
your systems installation and
service manual.
NEMA 4 Junction Box
(Optional):
If electrical control panel is to be
set remote from the pump sump a
NEMA 4 junction box should be
used to make power and control
connections. The Hydromatic
NEMA 4 junction box is provided
with compression connectors
for sealing all wires. No sealing
compound is needed to make
connections waterproof.
Wiring diagrams are provided with
panel for making connections.

pump starts. Allow pump to
operate until the level drops
to turn-off point.
5. Allow sump level to rise to
start other pump. Notice run
lights on panel; pumps should
alternate on each successive
cycle of operation.
6. Turn both H-O-A switches
to Off position and allow
sump to fill to the override
control level.
7. Turn both switches to Auto
position and both pumps
should start and operate
together until level drops to
turn-off point.
8. Repeat this operation cycle
several times before leaving
the job.
9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire
as sometimes a high leg
will exist. One leg can be
somewhat higher, 5 to 10%,
without causing trouble.
For excessive amp draw on
one leg, the power company
should be consulted.
Phase Converters:
Phase converters are generally not
recommended, but in cases where
only single phase current is
available phase converter can be
used. Be sure to size the phase
converter large enough for the
amp draw specified on the motor
nameplate, not necessarily by
motor horsepower. The warranty
on all three phase submersible
motors is void if operated with
single phase power through a
phase converter and 3 leg ambient
compensated extra-quick trip
overload protectors are not used.
The size wire to use from panel to
sump depends on motor size and
distance in feet.
Be sure each wire is checked
out so that a wrong connection
will not be made. An ohmmeter
or Megger can be used to check
wire continuity.
Installing Float Switch Controls:
The controls are supported by a
mounting bracket that is attached
to sump wall or cover or to the
NEMA 4 junction box.
Cord snubbers are used to hold
the cord in place. Control lever
can be changed at any time by
loosening the snubber and
readjusting cord length.
In either simplex or duplex
system the lower or turn-off
control is set just above the
top of volute so that the volute will
always be submerged during the
pumping cycle. The second
or turn-on control is set about
24 inches above the lower
turn-off control.
More distance between turn-on
and turn-off controls can be used,
but sewage may become septic
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended for
best operation.
If an alarm system is used, this
control is usually set about 6
inches above the override control.
Making Electrical Connections:
All electrical wiring must be in
accordance with the local code,
and only competent electricians
should make the installations.
Complete wiring diagrams are
on the inside cover of the panel.
All wires should be checked for
ground with an ohmmeter or
Megger after the connections
are made. This is important, as
one grounded wire can cause
considerable trouble.
IMPORTANT: If equipment
is not properly wired and
protected as recommended, the
warranty is void.
Heat Sensors and Seal Failure
Connections:
Be sure that heat sensor wires are
connected in series with the starter
coil. Connections are provided on
the terminal strip.
Pump
Operations
Starting System:
1. Turn H-O-A switch to
Off position, then turn on
main circuit breakers.
2. Open all discharge valves
and allow water to rise in
sump pump.
3. Turn H-O-A switch to Hand
position on one pump and
notice operation. If pump is
noisy and vibrates, rotation
is wrong. To change rotation
interchange any two line leads
to motor on 3ø only.
DO NOT INTERCHANGE
MAIN INCOMING LINES. If
duplex system, check second
pump in the same manner.
4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until one

Pump
Maintenance
NOTE: Any unauthorized field
repair voids the warranty, the
hazardous location rating, and
Factory Mutual approval.
If the heat sensor and seal failure
are hooked up properly, no
attention is necessary as long
as the seal failure indicator
light doesn’t come on. To ensure
continuity of the seal sensor
leads, a test light is provided on
intrinsically safe Hydromatic®
panels as standard equipment.
Pump should be checked every
quarter for corrosion and wear.
Maintenance:
As the motors are oil filled, no
lubrication or other maintenance
is required.
If the pump is used on a rail
system, it should be lifted once
every six months and checked for
corrosion and wear.
Generally these pumps give
very reliable service and can be
expected to operate for years
on normal sewage pumping
without failure.
Lightning:
In some areas where considerable
lightning occurs, it is recommended
that a lightning arrestor be installed
at the control panel to aid against
damage to the motor.
Field Service on Hydromatic
Hazardous Location Pumps:
If a Hydromatic hazardous location
pump is used in a hazardous
location, or if the pump is still
in warranty, the pump must be
returned to the factory for service
or repaired at an authorized
Factory Mutual Hydromatic
service center. Charges will not
be allowed if in warranty pump is
not taken to an authorized Factory
Mutual Hydromatic service center.
This will ensure the integrity of
the hazardous location rating of
the pump and comply with our
warranty requirements.
Field Service on Motor:
All submersible motors out of
warranty can be serviced in the
field by any reliable motor
service shop. Any pump, in
warranty, must be returned to the
factory for service or repaired
at an authorized Hydromatic
service center. Charges will not be
allowed if in warranty pump is not
taken to an authorized Hydromatic
service center.
When field service is performed on
a pump, these instructions should
be carefully followed.
Replacing Stator:
1. If stator only is damaged, it
may not be necessary to
completely dismantle pump
as stator and housing can be
lifted from pump without
disturbing seals or bearings.
2. Drain all oil from upper
housing, remove drain plug in
bottom of stator housing and
remove plug in top of housing
to allow air to enter.
3. After chamber is drained,
remove hold-down bolts and
lift off. Use care in lifting as
the seal failure connecting wire
must be disconnected before
housing is completely removed.
4. Set assembly on bench and
remove connection box. When
box is lifted off, connection
wires to motor will be
exposed. These wires will
probably be burned, but each
wire is tagged with a metal
marker giving wire number.
Cut the wires.
5
If the leads to the connection
box are burned, a complete
new connection box with new
wire must be used. The wires
are potted in with sealing
compound and a new unit must
be obtained from
the factory.
5. The stator is held in the
housing with a bolted-in end
ring and an outside locking
screw to prevent stator
from turning.
6. After ring is removed, turn
housing upright and bump on
hardwood blocks. This should
jar the stator loose and allow it
to drop out.
7. Thoroughly clean housing
before replacing new stator.
Replace stator and make all
wire connections to connection
box before replacing housing
on pump. This is important as
leads must be tucked behind
the windings by using hands
up through rotor core.
IMPORTANT: Use only
compression type insulated
connectors on the wires.
DO NOT TAPE LEADS AS
OIL WILL DETERIORATE
THE TAPE AND CAUSE
DAMAGE TO STATOR AND
BEARINGS.
8. Drain oil from seal chamber.
Check top bearing. If clean
and does not turn rough,
bearings can be reused and it
is not necessary to completely
dismantle pump to change
bearings. If bearings are
damaged with dirt or heat, they
must be replaced. Remember
to reinstall the upper bearing
load spring.
9. Before replacing stator housing
be sure outside lock screw is
in place and that O-ring is used
under head of bolt. A leak here
can cause a motor failure.

10. Replace stator housing onto
seal chamber and bolt in
place. Be sure seal failure
wire is connected before
housing is assembled.
Be sure back-off screws have
been loosened so that parts
can come metal to metal. Be
sure O-ring seal has been
replaced. If O-ring is nicked
or cut, replace with new rings.
This applies to all O-rings used
in assembly.
11. After all leads are reconnected
in the connection box, make
a high voltage ground test
on each wire. The only wire
that should show ground is
the green power lead and the
ground lead in the auxiliary
control cable.
12. For safety, complete pump
should be air checked under
water for leaks. Lay pump on
side for this oil filling with
oil fill hole upright. Do not
completely fill; leave oil about
1 inch below plug hole. Use
only Hydromatic®submersible
oil in this chamber. Replace
plug; use Permatex on threads.
Install air valve in top plug
opening of motor housing and
charge housing with about 10
psi of air. Be sure air is dry. Do
not use air line where water
may be trapped in the line.
Submerge complete unit under
water and check for leaks.
13. Refill motor chamber with
Hydromatic submersible oil.
Fill chamber until oil covers
top of the windings. Leave air
space in the top for expansion.
Use Permatex on plug threads.
Replacing Seals and Bearings:
1. Drain all oil from motor
chamber and seal chamber
as described.
2. Remove the motor housing
as described.
3. Remove bolts that hold seal
chamber to pump housing.
Use back-off screws to break
loose. With hardwood block,
tap end of impeller to loosen
from shaft. When free, remove
impeller from shaft.
4. Lift rotating assembly (rotor,
shaft and impeller) from pump
case and place horizontally
on bench.
5. Remove screw and washer
from end of shaft and then
screw socket head bolt back
into shaft. Using a screwdriver
on opposite sides behind
impeller apply force, then
tap on end of socket bolt to
break impeller loose from
taper shaft.
6. Remove key and then slide
seal off the shaft.
7. To remove seal plate, take out
socket head flat screws and
using screws in back off holes,
pry plate loose. This will
also force seal off if not
already removed.
8. Remove snap ring that
holds upper seal. Pull seal
if it is free. If not free, it
can be forced off when shaft
is removed.
9. Set assembly in upright
position and bump end of shaft
on hardwood block. This will
push the bearing from the
housing and will force upper
seal from shaft.
10. Use bearing puller to remove
bearings. Replace with new
bearings. Press only on
inner face of bearing when
replacing. Pressing on outer
face can damage the bearing.
IMPORTANT: Do not use
any of the old seal parts.
Replace with all new seals.
11. Thoroughly clean all castings
before replacing seals. One
grain of dirt between the seal
faces can cause failure.
12. Examine all O-rings for nicks
before using.
13. Use Locktite®on socket head
locking screw in end of shaft.
14. Before refilling chamber
with oil, air test as described
above and refill both chambers
with oil.
15. Always check all leads with
high voltage or with Megger
for grounds before operating
the pump.
Replacing Cords:
The power cord and heat sensor -
seal failure cord is potted into the
connection box cap, forming the
cord and cap assembly.
If cords require replacement due to
damage or cords being too short,
cord and cap assembly must be
replaced as a complete assembly
available from factory.
Check pump for proper rotation
before returning to normal service.
Disconnecting Pump Cords:
If a Hydromatic hazardous location
pump is to be removed from its
location, the pump cords may be
disconnected at control panel (on
sump mounted control panels) and
cord assembly taken with pump.
CAUTION: If cord openings
from sump to control panel are
open, gases from sump could
enter panel and an explosive
condition could exist.
Replacing Lower Seal, Impeller
or Volute:
The wet end components may
be repaired or replaced by an
authorized Hydromatic service
facility without compromising
the hazardous location rating to
the pump.
NOTE: Any time the seal is
disturbed, it must be replaced.

Pump
Troubleshooting
The following is a list of common
problems and their probable causes.
Pump will not start.
1. No power to the motor. Check
for blown fuse or open
circuit breaker.
2. Selector switch may be in the
Off position.
3. Control circuit transformer
fuse may be blown.
4. Overload heater on starter may
be tripped. Push to reset.
Pump will not start and
overload heaters trip.
1. Turn off power and check
motor leads with Megger or
ohmmeter for possible ground.
2. Check resistance of motor
windings. All 3 phases should
show the same reading.
3. If no grounds exist and the
motor windings check OK,
remove pump from sump
and check for clogged or
blocked impeller.
Pump operates with selector
switch in Hand position but will
not operate in Auto position.
1. This indicates trouble in the
float level control or the
alternator relay.
2. Check control panel
for trouble.
Pump runs but will not shut off.
1. Pump may be air locked. Turn
pump off and let set for
several minutes, then restart.
2. Lower float control may be
hung-up in the closed position.
Check in sump to be sure
control is free.
3. Selector switch may be in the
Hand position.
Pump does not deliver
proper capacity.
1. Discharge gate valve may
be partially closed or
partially clogged.
2. Check valve may be partially
clogged. Raise level up and
down to clear.
3. Pump may be running in
wrong direction. Low speed
pumps can operate in reverse
direction without much noise
or vibration.
4. Discharge head may be too
high. Check total head with
gauge when pump is operating.
Total head is discharge gauge
pressure converted to feet plus
vertical height from water
level in sump to center line of
pressure gauge in discharge
line. Gauge should be installed
on pump side of all valves.
Multiply gauge pressure in
pounds by 2.31 to get head
in feet.
5. If pump has been in service for
some time and capacity falls
off, remove pump and check
for wear or clogged impeller.
Motor stops and then restarts
after short period but overload
heaters in starter do not trip.
1. This indicates heat sensors in
the motor are tripping due to
excessive heat. Impeller may
be partially clogged giving
a sustained overload but not
high enough to trip overload
heater switch.
2. Motor may be operating out
of liquid due to a failed
level control.
3. Pump may be operating on a
short cycle due to sump being
too small or from water
returning to sump due to a
leaking check valve.

General Information
Attention:
This manual contains important
information for the safe use of this
product. Read this manual completely
before using this product and refer to it
often for continued safe product use. DO
NOT THROW AWAY OR LOSE THIS
MANUAL. Keep it in a safe place so that
you may refer to it often. Reasonable care
and safe methods should be practiced.
Check local codes and requirements
before installation.
Unpacking Pump:
Remove pump from carton. When
unpacking unit, check for concealed
damage. Claims for damage must be
made at the receiving end through the
delivery carrier. Damage cannot be
processed from the factory.
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.
CALIFORNIA PROPOSITION 65
WARNING:
This product and
related accessories contain chemicals
known to the State of California to
cause cancer, birth defects or other
reproductive harm.
Pumps Not Operating or in Storage:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 months or longer
and prior to electrical start-up.
Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 weeks or longer
and prior to electrical start-up.
Seal Failure:
An electrode probe is installed in the seal
chamber so if any water enters the chamber
through the first seal, the electrode will be
energized and a signal will be transmitted
to the sensing unit at ground surface
causing a red light to flash. The electrode
probe is installed in all units, but the
sensing unit is supplied at extra cost and
must be ordered.
In operation the seal failure unit indicates
only that there is some water in the seal
chamber. The pump will continue to
Three pumps operate together only if
sump level rises to the fourth control
(second override). This control also
brings on the third pump in case of failure
of either or both of the first two pumps.
Alarm Controls:
The alarm level is usually set above the
override level so the alarm will signal
only if the override level is exceeded.
However, some engineers prefer to have
the alarm level set below the override
level as it is possible for one pump to
fail and the other pump to operate on
the override level with the sump level
never reaching the alarm level. This
is particularly true in cases of low
inflow capacity.
Electrical Control Panel:
It is recommended that the Hydromatic
control panel be used with all pumps as
proper starter heaters and connections for
heat sensor wires are furnished.
The electrical equipment includes a
main circuit breaker for each pump, a
magnetic starter with overload protection
for each pump, an H-O-A switch and run
light for each pump, an electric alternator
and a transformer to provide appropriate
control circuit and alarms.
Overload Heaters:
Starters with 3 leg overload protection
must be supplied. The heaters must
be sized in accordance with the
nameplate amps on the motor housing.
The amp draw on these submersible
motors is slightly higher than
a corresponding horsepower surface
motor so heaters must be sized by the
nameplate rating.
IMPORTANT: Be sure the heat
sensor wires are connected in series
with the starter coil circuit.
Pump Installation
Installing Pump in Sump:
Before installing pump in sump lay it on
side and turn impeller manually. Impeller
may be slightly stuck due to factory test
water so it must be broken loose with
small bar or screwdriver in edge of
vanes. The impeller should turn freely.
Clean all trash and sticks from sump and
connect pump to piping.
operate without damage, but the seal
should be checked immediately after
failure is indicated.
The sensing unit is recommended on all
installations as good insurance against
motor failure.
Pump:
The submersible pumps are supplied
for 3 phase and for 200, 230, 460 or
575 volts. Power cable is supplied with
separate wire for ground. Be sure green
wire is connected to a good ground such
as water pipe or ground stake.
Heat Sensors:
All motors have heat sensor units
embedded in the motor winding to detect
excessive heat. The heat sensors are
set to trip at 105°C, so will not operate
if dangerous heat occurs. The sensors
automatically reset when motor cools to
safe temperature.
The sensors are connected in series with
the motor starter coil so that the starter is
tripped if heat sensor opens. The motor
starter is equipped with overload heaters
so all normal overloads are protected by
the starter.
IMPORTANT: If Hydromatic®
electrical starting equipment
is not supplied, the heat sensor
circuit must be connected in series
with the starter coil or warranty is
void.
Sump Level Control:
Sump level is controlled by Hydromatic
float switch controls. The float is held in
position in the sump by a weight attached
to the power cord above the float. The
cord supports the float and is adjusted for
height from the surface.
Typical duplex systems use three
controls: one set at turn-off, one set at
turn-on for one pump, and one set for
turn-on for two pumps. Pumps alternate
operation on each successive cycle.
Two pumps operate together only if
sump level rises to the third or override
control. The override control also brings
on the second pump in case of failure
of the first pump. Extra floats with
appropriate controls can be supplied for
alarm functions. Triplex systems use
four controls: one set at turn-off, one set
at turn-on for one pump, one set at turn-
on for two pumps, and one set at turn-on
for three pumps. Pumps alternate each
successive cycle.

3
A check valve must be installed on each
pump. A gate or plug valve in each pump
discharge line is also recommended.
This valve should be installed on the
discharge side of the check valve so if
necessary to service the check valve, the
line pressure can be cut off. Single pump
systems are sometimes installed without
a check valve where it is desirable to
self-drain the discharge line to prevent
freezing. This can be done only with
short discharge lines; otherwise water
will return to the sump and cause short
cycling of the pump.
NEMA 4 Junction Box (Optional):
A NEMA 4 junction box should be used
to make power and control connections.
The Hydromatic®NEMA 4 junction
box is provided with compression
connectors for sealing all wires. No
sealing compound is needed to make
connections waterproof.
Wiring diagrams are provided with panel
for making connections. The size wire
to use from panel to sump depends on
motor size and distance in feet.
Be sure each wire is checked out so that
wrong connections will not be made.
Installing Float Switch Controls:
The controls are supported by a mounting
bracket that is attached to sump wall or
cover or to the NEMA 4 junction box.
Cord snubbers are used to hold the cord
in place. Control lever can be changed at
any time by loosening the snubber and
readjusting cord length.
In either simplex or duplex system the
lower or turn-off control is set just above
the top of volute so that the volute
will always be submerged during the
pumping cycle. The second or turn-on
control is set about 24 inches above the
lower turn-off control.
More distance between turn-on and turn-
off controls can be used, but sewage
may become septic and excessive solids
may collect for the pump to handle. A
frequent pumping cycle is recommended
for best operation.
If an alarm system is used, this control
is usually set about 6 inches above the
override control.
Making Electrical Connections:
All electrical wiring must be in
accordance with the local codes,
and only competent electricians should
make the installations.Complete wiring
diagrams are glued to the inside cover of
the panel. All wires should be checked
for grounds with an ohmmeter or Megger
after the connections are made. This is
important, as one grounded wire can
cause considerable trouble.
IMPORTANT: If equipment is not
properly wired and protected as
recommended, the warranty is void.
Heat Sensors and Seal Failure
Connections:
Be sure that heat sensor wires are
connected in series with the starter
coil. Connections are provided on the
terminal strip.
Pump Operations
Starting System:
1. Turn H-O-A switch to Off position,
then turn on main circuit breakers.
2. Open all discharge valves and allow
water to rise in sump pump.
3. Turn H-O-A switch to Hand
position on one pump and notice
operation. If pump is noisy and
vibrates, rotation is wrong. To
change rotation interchange any two
line leads to motor on 3ø only. Do
not interchange main incoming
lines. If duplex system, check
second pump in the same manner.
4. Now set both H-O-A switches to
Auto position and allow water to
rise in sump until one pump starts.
Allow pump to operate until level
drops to turn-off point.
5. Allow sump level to rise to start
other pump. Notice run lights on
panel; pumps should alternate on
each successive cycle of operation.

8. Check top bearing. If clean
and does not turn rough, bearings
can be reused and it is not necessary
to completely dismantle pump to
change bearings. If bearings are
damaged with dirt or heat, they
must be replaced. Remember to
reinstall the upper bearing load
spring.
9. Before replacing stator housing, be
sure outside lock screw is in place
and that O-ring is used under head
of bolt. A leak here can cause a
motor failure.
10. Replace stator housing onto the seal
chamber and bolt in place. Be sure
the seal failure wire is connected
before the housing is assembled.
Be sure back-off screws have been
loosened so that parts can come
metal to metal. Be sure O-ring
seal has been replaced. If O-ring
is nicked or cut, replace with new
rings. This applies to all O-rings
used in assembly.
11. After all leads are reconnected
in the connection box, make
a high voltage ground test on each
wire. The only wire that should
show ground is the green power
lead and the ground lead in the
auxiliary control cable.
12. For safety, complete pump should
be air checked under water for
leaks. Lay pump on side for
this oil filling with oil fill hole
upright. Do not completely fill;
leave oil about 1 inch below
plug hole. Use only Hydromatic
submersible oil in this chamber.
Replace plug; use Permatex on
threads. Install air valve in top
plug opening of motor housing
and charge housing with about
10 psi of air. Be sure air is dry. Do
not use air line where water may
be trapped in the line. Submerge
complete unit under water and
check for leaks.
13. Refill motor chamber with oil. Use
Hydromatic special submersible oil.
Fill chamber until oil covers top
of windings. Leave air space in
top for expansion. Use Permatex on
plug threads.
6. Turn both H-O-A switches
to Auto position and allow sump to
fill to the override control level.
7. Turn both switches to Auto position
and both pumps should start and
operate together until level drops to
turn-off point.
8. Repeat this operation cycle several
times before leaving the job.
9. Check voltage when pumps are
operating and check the amp draw
of each pump. Check amps on each
wire as sometimes a high leg will
exist. One leg can be somewhat
higher, 5 to 10%, without causing
trouble. For excessive amp draw on
one leg, the power company should
be consulted.
Phase Converters:
Phase converters are generally not
recommended, but in cases where only
single phase current is available phase
converter can be used. Be sure to size the
phase converter large enough for the amp
draw specified on the motor nameplate,
not necessarily by motor horsepower.
The warranty on all three phase
submersible motors is void if operated
with single phase power through a phase
converter and 3 leg ambient compensated
extra-quick trip overload protectors are
not used.
Pump Maintenance
As the motors are oil filled no lubrication
or other maintenance is required.
Generally these pumps give very reliable
service and can be expected to operate
for years on normal sewage pumping
without failure.
Lightning:
In some areas where considerable
lightning occurs, it is recommended that
a lightning arrestor be installed at the
control panel.
Lightning arrestors are good insurance
against damage to an expensive motor.
Field Service on Motor:
All submersible motors out of warranty
can be serviced in the field by any
reliable motor service shop. Any pump in
warranty must be returned to the factory
for service or repaired at an authorized
Hydromatic®service center. Charges
will not be allowed if in warranty pump
is not taken to an authorized Hydromatic
service center.
When field service is performed on
a pump, these instructions should be
carefully followed.
Replacing Stator:
1. If stator only is damaged,
it may not be necessary to
completely dismantle pump as
stator and housing can be lifted
from pump without disturbing seals
or bearings.
2. Drain all oil from upper housing,
remove drain plug in bottom of
stator housing and remove plug in
top of housing to allow air to enter.
3. After chamber is drained, remove
hold-down bolts and lift off.
Use care in lifting as the seal
failure connecting wire must be
disconnected before housing is
completely removed.
4. Set assembly on bench and
remove connection box. When box
is lifted off, connection wires to
motor will be exposed. These wires
will probably be burned, but each
wire is tagged with a metal marker
giving wire number. Cut the wires.
If the leads to the connection box are
burned, a complete new connection
box with new wire must be used.
The wires are potted in with sealing
compound and a new unit must be
obtained from the factory.
5. The stator is held in the housing with
a bolted-in end ring and an outside
locking screw.
6. After the ring is removed, turn
housing upright and bump on
hardwood blocks. This should jar the
stator loose and allow it to drop out.
7. Thoroughly clean housing before
replacing new stator. Replace stator
and make all wire connections to
connection box before replacing
housing on pump. This is important
as leads must be tucked behind the
windings by using hands up through
rotor core.
IMPORTANT: Use only compression
type insulated connectors on the wires.
Do not tape leads as oil will deteriorate
the tape and cause damage to stator
and bearings.
