VSF Variable Speed and Flow Pump Installation and User’s Guide
INSTALLATION
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 that the pump is mechanically secured to the
equipment pad.
Be sure the pump 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 piping returns.
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 pool water level.
3. Install the pump a minimum of 3 feet (0.9 meters)
from the 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 excessive 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. 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. 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.
We also recommend 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.
See Figure 2.
Example: A 2.5-inch pipe requires a 12.5-inch (31.8
cm) straight run in front of the suction inlet of the pump.
This will help the pump prime faster and last longer.
Note: DO NOT install 90° elbows directly into the pump
inlet and outlet.
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
fixed wiring in accordance with the wiring rules.
Optional Keypad Relocation Kit
In special cases when the user lacks easy or
convenient access to the IntelliFloXF or IntelliProXF
VSF pump, a Keypad Relocation Kit (P/N 356904Z
[Almond] or 356905Z [Black]) may be purchased from
your local pool equipment supplier. This kit allows the
user to remove the keypad from the top of the drive and
mount the keypad in a fixed location with better access.
For installation instructions refer to the Keypad
Relocation Kit Installation Instructions provided with
the kit.
Fittings and Valves
1. Do not install 90° elbows directly into pump inlet.
2. Flooded suction systems should have valves
installed on suction and discharge pipes for
maintenance, however, the suction 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.
Only a qualified plumbing professional should install the IntelliFloXF
®
VSF Variable Speed and Flow Pump. Refer to
Important Pump Warning And Safety Instructions on pages i - ii for additional installation and safety information.
Note: IntelliFloXF VSF and IntelliProXF VSF pumps cannot be connected in series with other pumps.
