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.
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.
50 Cycle or WYE Delta:
For information and parts list for
50 cycle or wye delta start pumps
refer to Addendum S4HRC-701.
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.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic.
Pump:
The S4HRC submersible pumps
are supplied for 1 and 3 phase and
for 200, 230, 460 or 575 volts.
Pump is supplied 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
General
Information
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 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 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
