care ful ly. Reasonable care and
safe meth ods should be practiced.
Check
local codes and
requirements before installation.

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

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.
Pumps in Storage or Not
Operating:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting nonoperational 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 sens ing 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 im me di ate ly
after failure is indicated.
NOTE: Failure to install such
a device negates all warranties
by Hydromatic.
Pump:
The S submersible pump is
sup plied for 1 and 3 phase and for
200, 230, 460 or 575 volts. Pump
is sup plied with 30 feet of power
cord and/or 30 feet of auxiliary
control cord. Longer cable lengths
can be furnished but must be
specified at time of order. Power
cable is 4 wire with the green 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
General
Information
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
sen sors 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 over loads are protected
by the starter.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic.
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
mer cu ry tube switch sealed in a
solid polyurethane float. The float
is held in position in the sump by
weight at tached to the power cord
above the float. The cord supports
the float and is adjusted for height
from the sur face.
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 al ter nate operation on each
successive cycle.
