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
e󰀩ciency, use short, direct suction and return piping.
2. Install a minimum of 5 feet (1.5 meters) from the
inside wall of the pool and spa. Canadian
installations require a minimum of 9.8 feet
(3 meters) from the inside wall of the pool.
3. Install the pump a minimum of 3 feet
(0.9 meters) from a heater outlet.
4. Do not install the pump more than 10 feet
(3.1 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 3 inches (7.6 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 ve
(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.
Fittings and Valves
1. Do not install 90° elbows directly into suction port.
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 ve (5) 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
signicant 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.
Electrical Requirements
• Install all equipment in accordance with the National
Electrical code and all applicable local codes and
ordinances.
• A means for disconnection must be incorporated in
the xed wiring in accordance with the wiring rules.
