OPERATION
WARNING: Unexpected Startup Hazard
Disconnect and lockout power before
servicing. Failure to follow these instructions could
result in serious personal injury or death, or
property damage.
WARNING: Electrical Shock Hazard
Electrical connections to be made by a
qualified electrician in accordance with all
applicable codes, ordinances, and good practices.
Failure to follow these instructions could result in
serious personal injury or death, or property
damage.
PRE-START CHECKS
Before initial start of the pump, make the
following inspections:
a. Check alignment between pump and
motor.
b. Check all connections to motor and
starting device with wiring diagram. Check
voltage, phase, and frequency on motor
nameplate with line circuit.
c. Check suction and discharge piping and
pressure gauges for proper operation.
d. Check impeller adjustment, see specific
section for proper adjustment.
e. Turn rotating element by hand to assure
that it rotates freely.
f. Check driver lubrication.
g. Assure that pump bearings are properly
lubricated.
h. Assure that coupling is properly lubricated,
if required.
i. Assure that pump is full of liquid (See
Priming) and all valves are properly set
and operational, with the discharge valve
closed, and the suction valve open.
j. Check rotation. Be sure that the drive
operates in the direction indicated by the
arrow on the pump casing as serious
damage can result if the pump is operated
with incorrect rotation. Check rotation
each time the motor leads have been
disconnected.
WARNING: Rotating Components
Hazard
Do not operate pump without all guards in place.
Failure to follow these instructions could result in
serious personal injury or death and property
damage.
CAUTION: Seal Damage Hazard
Do not run pump dry, seal damage may
occur. Failure to follow these instructions could
result in property damage and/or moderate
personal injury.
PRIMING
If the pump is installed with a positive head
on the suction, it can be primed by opening
the suction and vent valve and allowing the
liquid to enter the casing.
If the pump is installed with a suction lift,
priming must be done by other methods such
as foot valves, ejectors, or by manually filling
the casing and suction line.
WARNING: Rotating Components
Hazard
Do not operate pump without all guards in place.
Failure to follow these instructions could result in
serious personal injury or death and property
damage.
STARTING
a. Close drain valves and valve in discharge
line.
b. Open fully all valves in the suction line.
c. Prime the pump.
NOTE: If the pump does not prime properly,
or loses prime during start-up, it should be
shutdown and the condition corrected before
the procedure is repeated.
d. When the pump is operating at full speed,
open the discharge valve slowly. This
should be done promptly after start-up to
prevent damage to pump by operating at
zero flow.
OPERATING CHECKS
a. Check the pump and piping to assure that
there are no leaks.
