Upstream Filtration
• The pump must be protected from debris in
the feed water such as sand, gravel, or other
particulate matter.
• A 20 micron filter must be installed upstream
of the pump inlet to protect against foreign
matter entering the system.
• Temporary strainers should be installed
before start up or after repairs to protect the
pump from possible debris.
Preparation For Pump Start Up
Start Up Precautions
WARNING
NEVER operate the pump equipment:
• Below the minimum flow rate.
• When dry.
• Without priming.
• Without proper guards and safety devices
installed.
• With the discharge valve closed.
• With the suction valve closed.
ELECTRICAL HAZARD
Refer to the motor name plate, electrical junc-
tion box cover, or wiring tag for proper wiring.
All electrical connections should be made by a
licensed electrician according to all local codes
and regulations. Be sure to follow all manufac-
turer’s instructions on motor lubrication. Ensure
motor rotational direction is correct according to
the arrow located on the motor adapter (Refer
to the
Horizontal/ or Vertical Motor Installation
section).
CAUTION
Electric motors may develop continual noise
over long periods. Proper ear protection should
be worn during pump operation. Most noise will
emanate from the electric motor. The noise level
of the pump is nominal and depends on its size
and operating conditions. The typical level can
range from 75dB to 85dB, measured at a dis -
tance of 1 meter (39 inches) around the pump.
Sound may vary due to hydraulic resonance,
valves and building walls. For applications were
a minimum noise level is required, the system
should be operated with the flow adjusted as
close to optimum efficiency as possible. Vibra -
tion may also occur and varies based on pump
size and operating conditions. As a reference,
typical vibration levels can reach .177” (4.5mm)
per second RMS. See vibration test records or
specifications sheet for more information.
Start Up Checklist
An additional
Start Up Check List
is available
in the rear of this manual. Use that section to
record initial operating conditions at pump start
up.
□
Flexible coupling set screws tightened.
□
Motor adapter guards installed.
□
All anchor bolts tightened to specifications.
□
All pipe couplings tightened to
manufacturers specifications.
□
Motor rotational direction correct.
□
Motor lubricated to manufacturers
specifications.
□
Alignment busing (if present) removed.
□
Final Pump Alignment
performed.
□
Inlet pressure indicator installed.
□
Inlet pressure switch (if applicable)
installed.
□
Outlet pressure indicator installed.
□
System pipes are clean and upstream
filtration in place.
□
System leak checked and all air vented
from system.
□
ALL safety devices in place.
Pump Start Up
1. Start pump and vent air from the system.
2. Verify that there are no leaks.
3. Activate the pump.
4. Inspect the system for leaks.
NOTES: Some mechanical seal leakage may
occur for about 60 seconds after pump start-
up. If the leakage continues longer than 60
seconds then proceed with the
Mechanical
Seal Replacement
procedure in the
Overhaul
Manual
.
5. Observe any unusual system noise or vibra -
tion.
6. If a vibration meter is available, record a
baseline vibration reading at this time in the
Start Up Record
section of this manual.
7. Adjust system valves and controls as need-
ed to obtain the desired operation.
