INSTALLATION --- SECTION B

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 provides protection for the pump
motor against excessive heat due to motor over-

loads and failure to start, as well as short circuit
protection for incoming power lines.

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 3R rainproof enclo-

sure with a padlockable front cover.

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 perfecting 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 Figures B---1 thru B---4.
