WARNING: Do not use the isolation/gate valve to throttle the pump as this may cause
loss of prime, excessive temperatures and damage to pump, voiding warranty.
2. Keep suction pipe free from air pockets.
3. Piping should be level or slope gradually downward from the source of supply.
4. No portion of the piping should extend below pump suction.
5. The size of the entrance from the supply should be one or two sizes larger than the
suction pipe.
6. The suction pipe must be adequately submerged below the liquid surface to prevent
vortices and air entrainment at the supply. See above illustrations.
Discharge Piping
1. Isolation and check valves should be installed in the discharge line. Locate the
check valve between the isolation valve and the pump. This will permit inspection of
the check valve. The isolation valve is required for priming, regulation of flow and
for inspection and maintenance of the pump. The check valve prevents pump or seal
damage due to reverse flow through the pump when the driver is off.
2. Increasers, if used, should be placed between the pump and check valves.
3. Cushioning devices should be used to protect the pump from surges and water
hammer if quick closing valves are installed in the system.
Final Piping Check
After connecting the piping to the pump, rotate the motor shaft to make sure that there
is no binding.
Wiring
Warning: Install, ground and wire according to local and National Electrical Code
requirements.
Install an all leg electrical power disconnect switch near the pump.
Disconnect and lockout electrical power before installing or servicing the pump.
Electrical supply MUST match motor’s nameplate specifications. Incorrect voltage can
cause fire, damage the motor and void the warranty.
Motors without built-in protection MUST be provided with contactors and thermal
overloads for single phase motors, or starters with heaters for three phase motors. See
motor nameplate.
Use only copper wire to motor and ground. The ground wire MUST be at least as large
as the wire to the motor. Wires should be color coded for ease of maintenance.
Follow motor manufacturer’s wiring diagram on the motor nameplate or terminal cover
carefully.
Warning: Failure to permanently ground the pump, motor and controls before
connecting to electrical power can cause shock, burns or death.
Rotation
Notice: Incorrect rotation may cause damage to the pump and voids the warranty.
