General Information

LOCATION:
Locate the pump as near the water source as practical. Make
the pipe run as short and straight as possible, especially if a
suction lift is required.
Careful attention should be taken to assure that net positive
suction head available (NPSHA) exceeds net positive suction
head required (NPSHR) by the pump or reduced performance
and severe pump damage may result. If in doubt, check
with your nearest Berkeley professional dealer. Install pump
in a clean, dry and drained location readily accessible for
inspection and maintenance. Provide ample ventilation.
FOUNDATION:
Refer to illustrations at right.
Heavy weights. Use care and proper
equipment when handling pump for installation. Pump should
be set on a concrete foundation which is sufficiently substantial
to absorb vibration and which provides a permanent and rigid
support.
PIPING:
System piping should be at least one commercial pipe size
larger than pump connections and flow velocity should not
exceed eight (8) feet per second. In pool installation, flow
velocity should not exceed six (6) feet per second.
NOTICE: Take care to align piping with pump case.
Misalignment or excessive pipe strain can cause distortion of
pump components resulting in rubbing, breakage and reduced
pump life.
Support pipe in such a way that no force is exerted on pump
connections. Check alignment as follows: with the pump shut
down and isolation valves closed, remove pipe flange bolts.
If the mating flanges come apart or shift, misalignment is
present and causing pressure on the connections. Adjust pipe
supports until flanges mate without any force. This procedure
can be done throughout piping system.
SUCTION PIPING:
Refer to Pages 10 and 11 for installation instructions for
swimming pool circulating pump applications. Refer to Pages
6 through 9 for recommended and not recommended practices
in suction connections in centrifugal installations.
DISCHARGE PIPING:
Refer to illustrations on Page 12 and 13 for recommended and
not recommended practices in discharge connections.
ELECTRICAL CONNECTION:
Hazardous voltage. Can shock, burn, or
cause death. All wiring should be done by a qualified
electrician. Disconnect power to pump before servicing.
Check voltage and phase stamped on pump motor nameplate
before wiring. Be sure they agree with your electric current
supply. They MUST be the same. If in doubt, check with your
local power company.
Refer to illustration on Page 14 for minimum recommended
pumping panel components that help safeguard your pump
during operation.

• There are several types of permanent pump/ foundation
installations in use. Those pictured above are typical.
• If grout is used, top of concrete should be left rough to
provide a good bonding surface.
• Foundation should slope away from pump to prevent
liquid from pooling.
