NOTE: Any unauthorized field
repair voids the warranty, the
hazardous location rating, and
Factory Mutual approval.
As the motors are oil filled, no
lubrication or other main te nance
is re quired.
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
in trin si cal ly safe Hydromatic
panels as standard equipment.
Pump should be checked every
quar ter for cor ro sion and wear.
Servicing instructions:
iMPOrTANT: read all

parts.
WArNiNg: Before handling
these pumps and controls, always
dis con nect the pow er first.

Field Service on Hydromatic
Hazardous Location Pumps:

hazardous location, or if the pump
is still in war ran ty, the pump must
be returned to the factory for
service or repaired in an
authorized
Factory Mutual
Hydromatic service center.
Pump
Maintenance
Charges will not be allowed if (in
war ran ty) the pump is taken to a
motor repair shop that is not an
authorized
Factory Mutual
Hydromatic service center. This
will ensure the integrity of the
hazardous location rating of the
pump and com ply with our
warranty re quire ments. Pumps out
of warranty and not used in a
hazardous location can be field
serviced
by any reputable
serviceman. When any field
servicing is per formed on a pump,
the fol low ing in struc tions should
be followed care ful ly.
Disconnecting Pump Cords:
If a Hydromatic hazardous
location pump is to be removed
from its loca tion, 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
con trol panels) and cord as sem bly
taken with pump.
CAUTiON: if cord openings
from sump to con trol panel are
open, gas es from sump could
enter panel and an explosive
condition could ex ist.
Pump cords may be disconnected
at pump by removing the cord and
cap assembly, unplugging sensor
wires, and re mov ing wire nuts.
After removal from pump, reinstall
wire nuts in cord and cap assembly.
CAUTiON: Do not reconnect
pow er 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
con nec tion 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
avail able from factory.
1. Remove cord and cap assembly
from con nec tion box.
2. Disconnect wires taking note
of color/num ber coding.
3. Connect wires of new cord and
cap as sem bly in same manner
as the old one was removed.
4. Check for moisture and dryout.
5. Reinstall cord and cap assembly
on con nec tion box taking care
not to pinch wires.
6. Check pump for proper
rotation before re turn ing to
normal service.
replacing Stator:
If motor winding is burned or
shorted, it can be rewound or
replaced with new factory wound
sta tor. 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
com plete ly dismantle pump as
stator and housing can be lifted
from pump without dis turb ing
seals or bearings.
2. Drain all oil from upper
housing. Remove drain plug
in bottom of bearing housing,
and re move con nec tion box to
allow air to enter.
3. When connection box is lifted
off, con nec tion wires to motor
will be exposed. These wires
are tagged with a metal
marker giving wire num ber.
Disconnect wires and remove
connection box.
