PREINSTALLATION INSPECTION
The pump and control box were inspected and
tested before shipment from the factory. Before in-
stallation, inspect the pump for damage which may
have occurred during shipment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads, and other obvious dam-
age.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after dry-
ing, check for loose hardware at mating sur-
faces.
c. The standard pump is furnished with 50 feet of
power cable. Inspect the cable for cuts or
damage.
d. Inspect the control box for cracks, dents, and
other obvious damage.
e. Check that all control box components are se-
curely attached to their mounting surfaces,
and the electrical connections are tight and
free of corrosion.
f. Compare the amperes, phase, voltage and
hertz indicated on the motor nameplate to the
ratings indicated for the control box.
g. Carefully read all tags, decals, and markings
on the pump assembly and the control box,
and perform all duties as indicated.
h. Check the pump and motor for any oil leaks.
An oil leak may indicate a cut O-ring or other
damage.
i. If the pump and control box have been stored
for more than 12 months, some of the compo-
nents or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump serv-
ice.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
Gorman-Rupp distributor or the factory to deter-
mine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
LUBRICATION
This pump series utilizes one lubrication cavity, lo-
cated just behind the seal plate. It is filled with pre-
mium quality submersible pump oil which lubri-
cates two shaft seals. The motor operates in air
and requires no lubrication.
The lower shaft seal prevents liquid from entering
the lubrication cavity, while the upper shaft seal
prevents oil leakage into the motor. The upper seal
also acts as backup protection in the event of lower
seal failure.
The lubrication cavity was fully lubricated when
shipped from the factory. Check the oil level before
installing the pump (see LUBRICATION in MAIN-
TENANCE AND REPAIR). An additional quart of
oil has been provided with the pump to top off" the
oil cavity. If the oil level is abnormally low, deter-
mine the cause before putting the pump into serv-
ice.
