INSTALLATION
Only a qualified plumbing professional should install
the Variable Speed Pump. Refer to 'Pump Warning
and Safety Instructions' at the beginning of these
instructions for additional installation and safety
information.
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 and return
piping.
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 the inside wall of the pool.
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 (ie 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, always install a valve on
both the pump suction and return lines so that the
pump can be isolated during routing maintenance.
However, it is also 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 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 90º elbows

Choose a 1-1/2 in. or 2 in. adapter to match your pipe
size. (See Figure 3).
Fittings and Valves
1. Do not install 90º 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.
