MAINTENANCE
With proper application and installation of
monitoring devices, periodic inspection of motor
seals is not required. Should a malfunction occur
the motor has been equipped with a moisture
detection system and thermal protection which
will provide advance warning of impending
failure allowing the user to plan a maintenance
program before failure occurs.
GENERAL NOTES: ALL PARTS
1. Reliancer Submersible Motors utilize an
explosionĆproof Class I, Groups C and D,
tandem seal design, with an oil chamber
separate from the winding area.
2. Wound Stators - Reliance Submersible MoĆ
tors utilize a wound stator which has been
pressed into the frame. The stator insulation
system has been designed for the temperaĆ
ture and electricalrating involved. If the motor
failure is analyzed to encompass a winding
failure, return the motor to an authorized ReĆ
liance Electric Service Shop.
3. Encapsulated Lead Connector Assembly -
The lead connector assembly has been
especially encapsulated to insure integrity of
the motor. The connector can be removed
from the motor in order to reconnect leads.
Should the lead connector assembly be
damaged or the integrity of the encapsulation
be in question, it is required that a replaceĆ
ment lead connector assembly be ordered
from Reliance Electric Company.

MOTOR INSPECTION
After assembly, run motor in shaft down position
for 30 seconds minimum to one minute
maximum to allow seals to seat; then check for
oil leakage. In some cases, a slight oil mist will
appear around the seal. Wipe clean after test.
PAINTING AND SHIPPING
Before painting motor, cover exposed seal.
Remove any paper, tape, etc., from seal area
before crating motor. These motors can be
shipped in shaft up or shaft down position. Care
must be taken that exposed seal is not damaged
during shipment. Carton must protect exposed
seal from dirt, dust and damage.
