Only a qualified plumbing professional should install the WhisperFlo
Warning And Safety Instructions" on pages ii - iii for additional installation and safety information.
Location
Be sure the pump location meets the following
requirements:
Note: Do not install this pump within an outer enclosure
or beneath the skirt of a hot tub or spa unless marked
accordingly.
1. Install the pump as close to the pool or spa as possible.
To reduce friction loss and improve efficiency, use
short, direct suction piping returns.
2. Install a minimum of 5 feet (1.52 meters) from the
inside wall of the pool and spa. Canadian installations
require a minimum of 9.8 feet (3 meters) from pool
water level.
3. Install the pump a minimum of 3 feet (.9 meters) from
the heater outlet.
4. Do not install the pump more than 10 feet (3 meters)
above the water level.
5. Install the pump in a well ventilated location protected
from excessive moisture (i.e., rain gutter downspouts,
sprinklers, etc.)
6. Install the pump with a rear clearance of at least 3
inches (76.2 mm) so that the motor can be removed
easily for maintenance and repair.
Piping
1. For improved pool plumbing, it is recommended to
use a larger pipe size. When installing the inlet and
outlet fittings (male adaptors), use thread sealant.
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. It is recommended 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 pipe
diameter
Example:
A 2 inch (50.8 mm) pipe requires a 10 inch (254
mm) straight run in front of the suction inlet of the
pump. This will help the pump prime faster and last
longer.

Fittings and Valves
1. Do not install 90° elbows directly into pump inlet.
2. Flooded suction systems should have gate valves
installed on suction and discharge pipes for
maintenance, however, the suction gate valve should
be no closer than five times the suction pipe diameter
as described in this section.
3. Use a check valve in the discharge line when using
this pump for any application where there is significant
height to the plumbing after the pump.
4. Be sure to install check valves when plumbing in
parallel with another pump. This helps prevent reverse
rotation of the impeller and motor.
