Installation
PIPING - GENERAL
Support both suction and discharge
piping independently at a point near
the pump to avoid putting a strain on
the pump housing. Start all piping
AT
THE PUMP.
Increase pipe diameter at both the
suction and discharge by one (1)
standard pipe size (minimum) to obtain
desired performance and flow rate.
Refer to Table I when sizing pipe for
your pumping system.
NOTE:
Do not use pipe with
smaller
diameter on the suction side of pump.
Do not allow pump or any system
component to freeze. To do so will void
warranty.
SUCTION PIPE
Increase pipe size from pump tapping
as shown in Table I.
Figure 1 depicts a recommended run of
pipe and fittings for the suction side of
a centrifugal pump. Please refer to this
illustration when choosing pipe and
fittings for your suction connection.
IMPORTANT:
All connections must be
air tight!
DISCHARGE PIPING
Increase pipe size from pump tapping
as shown in Table I. Figure 1 depicts a
recommended run of pipe and fittings
for the discharge. Install tee with
priming plug as close to pump as
possible.
SWIMMING POOL
SEE FIGURE 2
Install at least two hydraulically
balanced main drains for each pump
suction line. Main drain must be at least
three feet center to center.
The pump suction system
must
provide
protection against the hazard of suction
entrapment or hair entrapment and/or
entanglement. All suction outlet covers
must be maintained. They must be
replaced if cracked, broken, or missing.
If 100% of the pump’s flow comes from
the main drain system, the maximum
water velocity in the pump suction
hydraulic system must be six feet per
second or less even if one main drain
(suction fitting) is completely blocked.
The system must not be able to operate
with the pump drawing water from
only
one
main drain (that is, there must
be at least two main drains connected
to the pump whenever it is running).
However, if two main drains run into a
single suction line, the single suction
line may be equipped with a valve
which will shut off
both
main drains
from the pump.
ELECTRICAL
Hazardous voltage.
Can shock, burn, or
cause death. Disconnect power to motor
before working on pump or motor.
Ground motor before connecting to
power supply.
WIRING
Ground motor
before connecting
to electrical power supply. Failure to
ground motor can cause severe or fatal
electrical shock hazard.
Do not ground to a gas supply line.
