Pump
Operations
9. Repeat this operation cycle
several times before leaving job.
10.Check voltage when pumps are
operating, and check the
amp draw of each pump.
Check amps on each wire
as sometimes a high leg
will exist. One leg can be
somewhat higher by 5 to 10
percent without causing trouble.
For excessive amp draw on
one leg, the electric utility
company should be consulted.
Pump
Maintenance
As the motors are oil filled, no
lubrication or other maintenance
is required.
If the heat sensor and seal failure
are hooked up properly, no
attention is necessary as long
as the seal failure indicator
light doesn't come on. To ensure
continuity of the seal sensor
leads, a test light is provided on
intrinsically safe Hydromatic
panels as standard equipment.
Pump should be checked every
quarter for corrosion and wear.
Servicing instructions:
iMPOrTANT:
read
directions
before
any parts.
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.
Field Service on Hydromatic
Hazardous Location Pumps:
If
a
Hydromatic
location pump is used in a
hazardous location the pump must
be returned to the factory for
service.
integrity of the hazardous location
rating of the pump and comply
with our warranty requirements.
Pumps out of warranty and not
used in a hazardous location can
be field serviced by any reputable
serviceman. When any field
servicing is performed on a pump,
the following instructions should
be followed carefully.
Disconnecting Pump Cords:
If a Hydromatic
location pump is to be removed
from its location, one of two ways
may be used to disconnect the
pump cords from the rest of the
system.
Pump cords may be disconnected
at control panel (on sump mounted
control panels) and cord assembly
taken with pump.
CAUTiON: if cord openings
from sump to control panel are
open, gases from sump could
enter panel and an explosive
condition could exist.

replacing
Pump cords may be disconnected
at pump by removing the cord and
cap assembly, unplugging sensor
wires, and removing wire nuts.
After
removal
reinstall wire nuts in cord and cap

CAUTiON: Do not reconnect
power to a cord and cap assembly
while removing from pump.
replacing Cords:
The power cord and heat sensor - seal
failure cord is potted into the
connection box cap, forming the
cord and cap assembly.
If cords require replacement due
to damage or cords being too
short, cord and cap assembly must
be replaced as a complete assembly
available from factory.
1. Remove cord and cap assembly
from connection box.
2. Disconnect wires taking note
of color/number coding.
3. Connect wires of new cord and
cap assembly in same manner
as the old one was removed.
4. Check for moisture and dryout.
5. Reinstall cord and cap assembly
on connection box taking care
not to pinch wires.
6. Check
pump
for
rotation before returning to
normal service.
replacing Stator:
If motor winding is burned or
shorted, it can be rewound or
replaced with new factory wound
stator. Refer to sectional drawing
of pump and motor, and use the
following steps to remove and
replace stator.
1. If only the stator is damaged, it
may not be necessary to
completely dismantle pump as
stator and housing can be lifted
from pump without disturbing
seals or bearings.
