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.
