General
Information
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. Reasonable
care and safe methods should be
practiced. Check local codes and
requirements before installation.
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.
California Proposition 65 Warning:
This product and
related accessories contain chemicals
known to the State of California to
cause cancer, birth defects or other
reproductive harm.
Application:
These pumps are designed for
on-site residential sewage discharge
applications with a pH ranging from
6 to 9, specific gravities from 0.9 to
1.1, viscosities ranging from 28 to 35
S.S.U., and temperatures up to 140
degrees Fahrenheit.
Pumps Not Operating or
in Storage:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after sitting
nonoperational for 3 months or
longer and prior to electrical start-up.
Seal Failure Probes:
All hazardous location submersible
pumps have two factory-installed
moisture detectors (seal failure
probes). They are in a normally open
series circuit, in the seal chamber.
Under normal operating conditions,
the circuit remains open. If the
lower seal leaks and moisture enters
this chamber, the moisture would
settle to the bottom of the chamber
and will complete the circuit
between the moisture detectors.
This circuit must be connected to a
sensing unit and signaling device.
This is supplied in a Hydromatic
®
control panel.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic pumps.
Heat Sensors:
All motors in this family have heat
sensors on or embedded in the
motor winding to detect excessive
heat. This prevents damage to the
motor. If the sensor trips due to
excessive winding temperature, the
starter in the panel breaks power to
the pump. Once the sensor resets,
the starter is to be reset (automatic
for F.M.) for continued operation
of the pump. This circuitry is
supplied in a Hydromatic control
panel. The sensors are set to trip at
120° Celsius.
NOTE: Failure to install such
circuitry would negate F.M.
approval and all warranties by
Hydromatic pumps.
Power Cords:
The power cord and heat sensor
seal failure cord are potted into the
connection 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.
During normal maintenance
procedures, power cords should be
inspected for abnormal wear and
replaced accordingly.
Overload Heaters:
If the Hydromatic electrical panel
is not used, starters with 3-leg
overload relay must be supplied
on three-phase pumps. Each leg is
to have an identical heater sized
in accordance with the nameplate
amps on the motor housing. The
amp draw on these submersible
motors is slightly higher than a
corresponding horsepower surface
motor, so heaters must be sized by
the nameplate rating.
Single-phase pumps with capacitor
start have a run and a start winding,
each drawing a different current. To
adequately protect these windings
with the appropriate heaters, consult
the factory.
NOTE: Red lead is always
start winding of pump using
single-phase.
Pump Installation
Installing Pump in Sump:
Before installing pump in sump,
lay it on its side and rotate impeller.
Impeller may be slightly stuck due
to factory test water so it must be
broken loose with a small bar or
screwdriver in edge of vanes. The
impeller should turn freely. Do
not connect the power until after
this test.
Clean all trash and sticks from
sump and connect pump to piping.
A check valve must be installed on
each pump.
Location:
If pumps are installed in an
existing basin or concrete sump,
the piping can either be connected
permanently or rails and brackets
can be furnished for mounting to
walls of basin. In either case, be
sure the Hyromatic solids handling
ball check valve is used and that the
pumps are submerged in a vertical
position. The complete factory-built
packaged system is recommended
for the most satisfactory installation
and generally for the lowest cost
where expensive installation labor
is involved.
Making Electrical Connections:
All electrical wiring must be in
accordance with local code, and
