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 struc tions
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.
iMPOrTANT: read all
directions before replacing any
parts.
Pump:
The hazardous location
submersible pump family was
designed in ac cor dance with
requirements
for haz ard ous
locations. These pumps, if
connected prop er ly, will provide
years of trouble-free service. If
ser vic ing is required, the repair
should be done by a Hydromatic
approved ser vice center.
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 Probes:
All our hazardous location
submersible pumps have two
factory
installed mois ture
detectors (seal failure probes).
They are in a normally open series
cir cuit, in the seal chamber. Un der
normal operating conditions, the
circuit remains open. If the lower
seal leaks and moisture enters this
cham ber, the moisture would
settle to the bottom of the
chamber and will com plete the
circuit between the mois ture
detectors.
This circuit must be connected
to a sensing unit and signaling
device. This is supplied in a
Hydromatic built control panel.
NOTE: Failure to install such a
device negates all war ran ties by
Hydromatic pumps.
General
Information
Heat Sensors:
All motors in this family have
heat sensors on or embedded
in the motor winding to detect
ex ces sive heat. This prevents
damage to the motor. If sen sor
trips due to excessive winding
tem per a ture, starter in panel
breaks power to the pump. Once
sensor re sets, the starter is to be
automatically reset for FM for
continued operation of the pump.
This circuitry is supplied in a
Hydromatic control panel.
The sensors are set to trip at
130°C (266°F).
NOTE: Failure to install such
circuitry would negate FM
ap prov als and all warranties by
Hydromatic pumps.
Power Cords:
The power cord and heat sensor
seal failure cord are potted into
the con nec tion box cap. The cords
must not be spliced.
NOTE: Each cable has a green
lead. This is the ground wire
and must be grounded properly
per NEC and/or local codes.
Cords should be in spect ed for
abnormal wear and replaced
ac cord ing ly.
Overload Heaters:
If the Hydromatic electrical panel
is not used, start ers with
3 leg overload relay must be
supplied on 3 phase pumps. Each
leg is to have an iden ti cal heater
sized in accordance with the
nameplate amps on the motor
hous ing. The amp draw on these
sub mers ible motors is slightly
higher than a cor re spond ing
horsepower sur face motor, so
heat ers must be sized by the
nameplate rating. To adequately
