INSTALLATION
Only a qualified plumbing professional should install
the pump. Refer to "Important Safety Instructions"
on pages i - ii for additional installation and safety
information.
Note: The pump should not be connected in series
with other pumps.
Location
Be sure the pump location meets the following
requirements:
1. Install the pump a minimum of 5 feet (1.5 m)
from the inside wall of the pool. Canadian
installations require a minimum of 9.8 feet (3 m)
from the inside wall of the pool.
2. Install the pump a minimum of 3 feet (0.9 m)
from a heater outlet.
3. Do not install the pump more than 10 feet (3.1
m) above the pool water level.
4. Provide at least 3-inch (7.6 cm) of side and rear
clearance for motor disassembly and removal.
5. Provide at least 6-inch (15.2 cm) of top
clearance for drive disassembly and removal.
6. Install the pump in a well ventilated location
protected from excessive moisture, dirt and heat
(i.e., rain gutter downspouts, sprinklers, etc.)
7. Secure the pump to the equipment pad at the
two anchor points located under the pump volute.
Anchor points are sized for up to 3/8-inch concrete
anchors.
8. Do NOT install this pump within an outer enclosure
or beneath the skirt of a hot tub or spa unless
marked accordingly.
Plumbing and Fittings
1. Provided union kit allows for easy plumbing to
a variety of pipe diameters. See UNION KIT
OPTIONS.
2. For improved plumbing a larger pipe size should be
used.
3. To reduce friction loss and improve efficiency, short
and direct suction and return lines are best.
4. Suction line diameter should be the same or larger
than the return line diameter.
5. Do not install 90° elbows directly into the pump inlet
or outlet.
6. Valves, elbows or tees installed in the suction line
should be no less than five times the suction pipe
diameter from the pump inlet.
Example: A 2-inch pipe requires a 10-inch (25.4
cm) straight run from the suction inlet. This will
help the pump prime faster and last longer.

Valves
1. Flooded suction systems should have valves installed
in both the pump suction and return lines. This allows
the pump to be isolated during routine maintenance.
2. Install a check valve in the return line when using this
pump for any application where there is significant
height to the plumbing after the pump.
3. Install check valves when plumbing in parallel with
another pump. This helps prevent reverse rotation of
the impeller and motor.
