General
Information

Thank you for purchasing your
Hydromatic pump. To help ensure
years of trouble-free op er a tion,
please read the fol low ing manual
carefully.

Before Operation:

Read the following in structions
care ful ly. Reasonable care
and safe meth ods 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 con tin ued safe product use.
DO NOT THROW AWAY OR
LOSE THIS MAN U AL. Keep
it in a safe place so that you may
refer to it often.

Unpacking Pump:

Remove pump from carton.
When un pack ing unit, check for
con cealed damage. Claims for
damage must be made at the
receiving end through the delivery
carrier. Dam age 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.

Pump

Shipping:

When unpacking unit check
for concealed damage. Claim
for damage must be made at
the receiving end through the
delivering carrier. Damage cannot
be processed from the factory.

Pumps in Storage or Not
Operating:

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 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 an alarm
function to energize.

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.

N OTE: Failure to install such a
device negates all warranties by
Hydromatic.

Pump:

The S4F submersible pump is
supplied for 1 and 3 phase and
for 200, 230, 460 or 575 volts.
Power cable is supplied with the
green 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.

NOTE: Failure to install such a
device negates all warranties by
Hydromatic pumps.

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. Connection
diagram is included in this
manual.

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 turn­on for one pump, one set at turn­on 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.

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 warranty is void.

Hydromatic electrical equipment
is installed in a weather-proof
NEMA 3R enclosure. The
electrical equipment includes

Installation
Instructions

otherwise water will return to the
sump and cause short cycling of
the pump.

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 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.

Single phase pumps with
capacitor start have a run and
a start winding, each drawing a
different current. To adequately
protect these windings with
the appropriate heaters, consult
the factory.

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,

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 the 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.

Be sure each wire is checked out so
that wrong connection will not be
made. An ohmmeter or Megger can
be used to check wire continuity.

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 Hydr-O-Rail system,
the pumps will be equipped with
guide brackets and hydraulic
sealing flange.
