Gorman-Rupp Pumps SE2C3 115V 1P 1483930 and up - Manual (Page 16)

SE SERIES OM−06492
PAGE C − 3 OPERATION
As viewed from the top, the pump should kick in a
counterclockwise direction; this will indicate that
impeller rotation is correct.
If the pump kicks in a clockwise direction, impeller
rotation is incorrect and the pump must be re-
turned to the factory or a Gorman-Rupp authorized
Submersible Repair Center. Since the pump is
powered by a single-phase motor, the direction of
rotation can not be altered by interchanging motor
leads at the control box.

OPERATIONAL CHECKS
Starting And Stopping
If an optional control box is used, follow the instruc-
tions accompanying the control box, start the
pump, and run any recommended checks.
After the pump has been installed in a wet well so
that it is fully submerged, start the pump as follows.
If wired into an optional manual switch, trip the
switch within the rainproof enclosure to start or
stop the pump.
If the pump is wired into an optional automatic liq-
uid level control box, set the control box selector
switch to HAND; the pump will continue to run until
the switch returned to OFF, or reset to AUTO.
If desired to operate the pump in the automatic
mode, set the selector switch to AUTO; pump op-
eration will be controlled by the optional float
switch. To terminate automatic mode, move the se-
lector switch to OFF or HAND.
Moving the control box selector switch to
OFF does not terminate incoming power
through the field wiring connected to the
control box.
It is recommended that a check valve or throttling
valve be installed in the discharge line if there is any
possibility of siphoning or back flow when the
pump is shut off.
Operational Checks
Check the pump for proper operation when first
started and periodically thereafter to identify minor
problems.
Check the pump for unusual noises or excessive
vibration while it is operating. If noise or vibration
is excessive, stop the pump and refer to the trou-
bleshooting chart for possible causes.
Check the pump strainer screen for clogging
caused by stones, sticks, or other debris. Clean
the strainer screen when required. In some cases,
stopping the pump momentarily may back flush
the strainer screen, purging most of the debris
from it. If this fails to clean the screen, remove the
pump from the sump and remove the debris manu-
ally. See PUMP DISASSEMBLY in the Mainte-
nance And Repair manual.
Never introduce air or steam pressure
