Mechanical Installation
1.
Carefully remove the pump assembly (or pump and
strainer pot assembly) from its shipping packaging.
2.
Determine the installation location of the pump and
strainer pot assembly. Ensure that adequate space
and lighting is provided for routine maintenance.
3.
It is good practice to install a valve on the suction
line before this unit and on the return line after the
pump so that both items can be isolated for routine
maintenance.
4.
Check that a section of straight pipe, with a length
that is five times its diameter, is installed between
the suction side of the pump and the first elbow. See
Figure 8.
5.
Suction lines should be as large as the suction port
of the pump. All piping must be air tight. Keep
all suction lines below pool water level until just
before the pump. Suction lines should slope toward
the pump.
6.
Connect the pump to the suction pipe using a 6"
ANSI-150 flange kit. Tighten the flange bolts to no
more than 20-foot pounds. Excessive torque may
damage the pump.
7.
Connect the pump to the discharge pipe using a 4"
ANSI-150 flange kit. Tighten the flange bolts to no
more than 20-foot pounds. Excessive torque may
damage the pump.
8.
The weight of the piping should be supported
independently and not carried by the pump.

9.
Plan carefully the layout of adjacent plumbing
including cutting pipe to the exact length and
ensuring that the flange will be aligned and square
with the strainer pot or pump assembly. Note that
the strainer pot must be installed so that water flow
travels into the upper flange and out the bottom
flange.
NOTE:
If the strainer pot assembly is installed as a
stand alone unit, another straight piece of pipe at least 76
cm (30") long should be installed to connect the strainer
assembly to the pump housing. Glue plumbing in place
once you are certain that fit ups are correct.
Use large diameter flat washers (at least 1-5/16 in.
outer diameter) between the hex nut and the strainer
pot assembly flanges to properly distribute the
clamping forces on the flanges. Tighten the flange
bolts to 27.1 newton meter (20 ft-lb) unless otherwise
specified by the flange manufacturer. If it is not
possible to use a torque wrench then care should be
taken not to over tighten the flange bolts. Failure to
follow the above instructions can result in damaging
the strainer pot flanges.
Suction and discharge piping must be supported
by an appropriate system of supports or hangers.
Inadequately supported pipe can cause excessive
loads to be transmitted to the strainer pot assembly
resulting in a structural failure that could result in
flooding and property damage.
3.4
Electrical Installation
WARNING
Single phase pump models include built-in manual
reset thermal overload protection to shut off the
motor in the event the temperature becomes
excessive (as a result of mechanical or electrical
problems; such as low voltage, poor ventilation,
overloaded lines, etc.). The motor thermal protection
must be manually reset to commence operation after
overload conditions have been corrected.
3-Phase pump motors are NOT thermally protected.
Motor protection must be provided by the installer in
accordance with local code.
3.4.1
Voltage Checks
Note: Do not try to connect three-phase motors to
single phase power supply or single phase motors
to three-phase power supply.
The correct voltage, as specified on the pump data plate,
is necessary for proper performance and long motor
life. Incorrect voltage will decrease the pump's ability to
perform and could cause overheating, reduce the motor life,
and result in higher electric bills.
