TAURUS™ VS Variable Speed Pump Installation and User’s Guide
INSTALLATION
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.
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.
Only a qualified plumbing professional should install the Taurus™ VS Variable Speed Pump. Refer to “Pump Warning
And Safety Instructions” on pages ii-iii for additional installation and safety information.

Location
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 body of water
as possible. To reduce friction loss and improve
efficiency, use short, direct suction and return piping.
2. Install a minimum of 5 feet (1.52 meters) from the
perimeter of the body of water. Canadian installations
require a minimum of 9.8 feet (3 meters) from the
inside wall of the body of water.
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 (3.1 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 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 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 or outlet.
