Section 3
Installation
• Install the pump as near to the pool as practical.
• Use a direct and short suction line with continuous slope in order to avoid long priming times.
• The pump should be placed on a flat, solid foundation, high enough to prevent flooding of the motor.
• Install the filter and pump in a sheltered location, ensuring ventilation and adequate access for servicing.
• Do not mount electrical controls directly over pump.
• Provide adequate floor drainage to prevent flooding.
• Size all piping adequately and keep the number of elbows to a minimum.
• Independently support the pipe near the suction and discharge of the pump in order to reduce the strain.
• Avoid overtightening pipe connections. Use only pipe sealants formulated for plastics. Do not use petroleum based
products. It is essential that the suction line is free of air leaks. The suction line should always be at least the same
size as the suction inlet of the pump.

Union Adapter Installation
The following describes how to install the locking union adapter onto the pump.
1. Glue PVC union adapter fitting to PVC pipe.
Adapter accepts 75mm PVC pipe internally
or a 3" PVC coupling externally. Be sure that
the groove for the retainer ring is on the end
opposite your glue joint.
2. Slip nut on fitting. Place the flat side of
the retainer ring against the adapter on the
grooved end. Gently flex the locking clip union
nut retainer ring into place on the adapter. Start
snapping it into the groove on one end of the
ring and work your way around.
3. Slide the nut over the ring and attach it
to the pump. HAND TIGHTEN THE NUT to
secure in place.
Section 5
Electrical Installation
The electrical motor must be wired by a professional according to this installation instruction and all applicable local
regulations. The professional installer should foresee that the motor has sufficient motor protection. All electrical data
should be utilized from the motor nameplat.
The supply voltage should be within ± 5% of the design voltage, specified on the nameplate of the motor.
