GENERAL INFORMATION
Review all SAFETY information in Section A.
This section is intended only to summarize recom-
mended installation practices for the control box. If
there are any questions concerning your specific
application, contact your Gorman-Rupp distributor
or the Gorman-Rupp Company.
PREINSTALLATION INSPECTION
The control box was inspected before shipment
from the factory. Before installation, inspect the
control for damage which may have occurred dur-
ing shipment. Check as follows:
a. Inspect the control box for cracks, dents, and
other obvious damage.
b. Check that all control box components are se-
curely attached to their mounting surfaces,
and that the electrical connections are tight
and free of corrosion.
c. Compare the amperes, phase, voltage and
hertz indicated on the pump motor nameplate
to the ratings indicated for the control box.
d. Carefully read all tags, decals, and markings
on the control box.
If anything appears to be abnormal, contact your
Gorman-Rupp distributor or the factory to deter-
mine the repair policy. Do not put the control box
into service until appropriate action has been
taken.
CONTROL BOX INSTALLATION
The control box furnished with the
pump is designed to operate the pump.
The control box provides overload pro-
tection and power
control. Do not con-
nect the pump motor directly to the in-
coming power lines.
Enclosure
The control box is a NEMA Type 10, MSHA certified
enclosure.
The enclosure is not designed to be
watertight, and should not be submerged.
No mounting hardware is furnished with the con-
trol box. Secure the control box vertically on a level
surface, above flood level. The control should be
mounted on a flat surface. If the mounting surface
is not perfectly flat, it may be necessary to use
shims (not supplied) with the enclosure.The box
should be easily accessible to the operator, and lo-
cated close enough to the pump to avoid exces-
sive voltage drop due to cable length.
Failure to mount the control box vertically
on a level surface may affect operation of
the pump controls.
After the box is securely installed, make certain the
front cover latches properly before installing any
electrical lines.
CONTROL BOX DIMENSIONS
For the approximate physical dimensions of your
control box, refer to Figure B-1.
