Only a qualified plumbing professional should install the WhisperFloXF
Variable Speed Pumps. Refer to "Important Safety Instructions" on pages i - ii for additional installation and safety
information.

Location

Note: Do not install this pump within an outer enclosure
or beneath the skirt of a hot tub or spa unless marked
accordingly.
Note: Ensure the pump is secured to the equipment
pad.
ENSURE THE INSTALL LOCATION MEETS THE
FOLLOWING REQUIREMENTS:
1. Install the pump as close to the pool or spa as
possible. To reduce friction loss and improve
efficiency, use short, direct suction and return piping.
2. Install a minimum of 1.5 meters from the inside wall
of the pool and spa.
3. Install the pump a minimum of 1 meter from a
heater outlet.
4. Do not install the pump more than 3 meters
above the water level.
5. Install the pump in a well ventilated location
protected from excess moisture (i.e. rain gutter
downspouts, sprinklers, etc.).
6. Install the pump with a rear clearance of at least
7.5 cm so that the motor can be removed easily
for maintenance and repair. See Figure 1.

Piping

1. For improved pool plumbing, it is recommended to
use a larger pipe size.
2. Piping on the suction side of the pump should be the
same or larger than the return line diameter.
3. Plumbing on the suction side of the pump should be
as short as possible.
4. For most installations Pentair recommends installing
a valve on both the pump suction and return lines
so that the pump can be isolated during routine
maintenance. However, we also recommend that
a valve, elbow or tee installed in the suction line
should be no closer to the front of the pump than five
(5) times the suction line diameter. See Figure 2.
Example: A 2.5 inch pipe requires a 12.5 inch
(31.8 cm) straight run in front of the suction port.
This will help the pump prime faster and last
longer.
Note: DO NOT install 90° elbows directly into the
suction or discharge ports.
