Thank you for purchasing your
Hydromatic®pump. To help
ensure years of trouble-free
operation, please read the
following manual carefully.
Before Operation:
Read the following instructions
carefully. Reasonable care and
safe methods should be practiced.
Check local codes and
requirements before installation.
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.
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. The S4LRC submersible pumps
are supplied for 3 phase and
for 460 and 575 volts. Pump is
supplied with 30 feet of power
cord and/or 30 feet of auxiliary
General
Information
control cord. Longer cable lengths
can be furnished but must be
specified at time of order. Power
cable is 3 & 4 wire with separate
wire for ground. Be sure green
wire is connected to a good
ground such as water pipe or
ground stake. The auxiliary cable
for seal failure and heat sensors is
also 4 wire color coded.
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 3 leg 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 on motor is void.
Connection diagram is included
in this manual.
Sump Level Control:
Sump level is controlled by
Hydromatic 3900 mercury switch
controls. The 3900 control is a
mercury tube switch sealed
in a solid polyurethane float.
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
Pump
Information
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.

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.
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 Control:
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.
IMPORTANT: If Hydromatic
electrical controls are not used
and the motor fails because of
improper components or if the
heat sensors are not properly
connected, the motor guarantee
is void.
Hydromatic electrical equipment
is installed in a weatherproof
NEMA 3R enclosure.
WARNING: Do not open swing
cover until you have first
disconnected the power.

Pump
Information
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 115 volts for control
circuit and alarms.
Overload Heaters:
If the Hydromatic electrical panel
is not used, starters with 3 leg
overload protection must be
supplied. On 3 phase pumps 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: If other than
Hydromatic starters are used be
sure the heat sensor wires are
connected in series with the
starter coil circuit. Typical
wiring diagrams are included.
HYDR-O-RAIL:
If the pump or pumps are to be
used with the HYDR-O-RAIL
system, the pumps will be
equipped with guide brackets and
hydraulic sealing flange.
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.
NEMA 4 Junction Box
(Optional):
If electrical control panel is to be
set remote from the sump pump,
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.
An extra set of diagrams is included
so that one set can be used in the
sump when making connections.
The size wire to use from panel to
sump depends on motor size and
distance in feet.
The table on page 3 can be used as
a guide for wire size.
Be sure each wire is checked out
so that wrong connections will not
be made.

Installing 3900 Mercury
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.
Some engineers as described
previously prefer to have the
alarm control set below the
override control.
Making Electrical Connections:
ALL ELECTRICAL WIRING
MUST BE IN ACCORDANCE
WITH LOCAL CODE,
AND ONLY COMPETENT
ELECTRICIANS SHOULD
MAKE THE INSTALLATIONS.
Complete wiring diagrams are
glued to the inside cover of the
panel, and an additional set of
prints is included for use in
making the installation. All wires
should be checked for grounds
with an ohmmeter or Megger after
the connections are made. This is
important, as one grounded wire
Pump
Operations
can cause considerable trouble.
(See Fig. 1.)
IMPORTANT: If equipment is
not properly wired and protected
as recommended, the motor
guarantee is void.
NOTE: For wiring diagram for
wye delta see Addendum
S4LRC-701.
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; see
wiring diagram.
If seal failure unit is used, connect
as shown with seal failure system.
If seal failure unit is not used, the
two seal failure wires are left
open. DO NOT CONNECT
POWER TO THESE LINES AT
ANY TIME. (See Figs. 2 and 3.)
Starting System:
1. Turn the 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

Operations
lights on panel; pumps should
alternate on each successive
cycle of operation.
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 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.
As the motors are oil filled no
lubrication or other maintenance
is required.
If a seal failure unit is used, no
attention is necessary as long as
the seal shows satisfactory operation.
If seal failure is not used, the
pump should be lifted once every
two years and the oil be drained
from the seal chamber to check for
water.
If the pump is used on a
HYDR-O-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.
Complete data on lightning
arrestors and cost are available
from the factory. Lightning
arrestors are good insurance
against damage to an expensive
motor.
Servicing Instructions:
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.
A septic pump condition may
exist and if entry into sump is
necessary, provide proper safety
precautions per latest OSHA
requirements; do not enter sump
until these precautions are
strictly adhered to.
Failure to heed above cautions
could result in injury or death.
Field Service on Motor:
All S4LRC submersible motors
can be serviced (out of warranty)
in the field by any reliable motor
service shop. Any pump (in
warranty) must be returned to the
factory for service or repaired in
an authorized Hydromatic service
center. Charges will not be
allowed if (in warranty) pump is
taken to a motor repair shop that is
not an authorized Hydromatic
service center.
When field service is performed
on a pump, these instructions
should be carefully followed.
Replacing Stator:
If motor winding is burned or
shorted it can be rewound or
replaced with new factory wound
stator. Refer to sectional drawing
of pump and motor and use the
following steps to remove and
replace 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.
See sectional drawing.

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 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 chamber. If
oil is clean and no water is
present, seals can be considered
satisfactory to reuse.
9. 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. See additional
instructions on replacing seals
and bearings. Remember to
reinstall the upper bearing
load spring.
10.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. If a
new stator has been used, it
will be necessary to drill into
the stator lamination for a
holding socket for bolt (29⁄64 dia.
drill, 1⁄2" deep, and 1⁄2-20 UNF,
3⁄8deep into the stator). This
holding spot is drilled through
the bolt hole when the stator
is bolted in place with the
end ring.
11.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 ring.
This applies to all O-rings used
in assembly.
12.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.
13.For safety, complete pump
should be air checked under
water for leaks. If seals were
OK, refill seal chamber with
oil. Lay pump on side for this
oil filling with oil fill hole

8
upright. Do not completely fill;
leave oil about 1 inch below
plug hole. Use only high grade
transformer oil or regular
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.
14.Refill motor chamber with oil.
Use high grade transformer
oil or Hydromatic special
submersible oil. Fill chamber
until oil covers top of windings.
Leave air space in 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 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 pry on each
side of shoulder of shaft sleeve
to remove. Seal should come
off with sleeve. If sleeve is not
free, leave in place and push
off when seal plate is removed.
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. Remove 4 bolts that hold bearing
housing in place (on units built
prior to 2/14/78). 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. Bearings
are standard size that can be
obtained from any bearing supply
house or can be obtained from
Hydromatic factory.
11.Important: Do not use any of
the old seal parts. Replace with
all new seals.
12.Thoroughly clean all castings
before replacing seals. One
grain of dirt between the seal
faces can cause failure.
13.Examine all O-rings for nicks
before using.
14.Be sure key is in place in notch
of shaft sleeve to prevent
sleeve from turning.
15.Use Locktite on socket head
locking screw in end of shaft.
16.Before refilling chamber with
oil, air test as described above.
17.Refill both chambers with oil
as described above.
18.Always check all leads with
high voltage or with Megger
for grounds before operating
the pump.

Below is a list of common problems
and the probable causes:
WARNING: Before handling
pumps and controls, always
disconnect power first. Do
not smoke or use sparkable
electrical devices or flame in a
septic (gaseous) or possible
septic sump.
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. To check for defective 3900
control, put selector switch in
Auto position and turn off
main power. Put a jump wire
between 2 and 3 on terminal
strip. Turn on power and
if pump starts, trouble is in
the lower 3900 control.
Replace control.
If pump does not start, turn
off power, remove jumper
from 2 and 3 and put jumper
wire between 1 and 2
terminals.
Turn on power and if pump
starts, trouble is in upper control.
Replace control.
If pump does not start, turn off
power and put jumper between
2 and 3 and 1 and 2 and turn on
power. If pump starts, both
lower and upper controls are
defective. If pump still does not
start, trouble is in the alternating
relay. Replace with new relay.
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
presure 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. All Hydromatic
S4LRC submersible motors
can operate for extended periods
out of water without burning
up the winding, but the heat
sensors give motor prolonged
life by controlling winding
temperature.
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.
