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.
Pump:
The hazardous location
submersible pump family was
designed in ac
cor
dance with
requirements for
haz ard ous
locations. These pumps, con nect ed
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 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. Under
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 Pump.
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
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
120°C (248°F).
NOTE: Failure to install such
circuitry would negate FM
approvals and all warranties by
Hydromatic Pump.
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.
