Pump Mounting
Install pump on a firm, level base or pad to meet all local and national codes. Fasten pump to base or pad with
screws or bolts to reduce vibration and stress on pipe or hose joints. The base MUST be solid, level, rigid, and
vibration free.
Pump mount must:
 Allow pump inlet height to be as close to water level as possible.
 Allow use of short, direct suction pipe (to reduce friction losses).
 Allow for ball valves in suction and discharge piping.
 Be protected from excess moisture and flooding.
 Allow adequate access for servicing pump and piping.
 Incorporate a straight portion of pipe prior to pump inlet no less than (5) pipe diameters in length.

Pipe Size Flow rate Water Velocity Pipe Size Flow rate Water Velocity
inches [mm] GPM [Liter/Min] ft/sec [meters/sec] inches [mm] GPM [Liter/Min] ft/sec [meters/sec]
1 ½” 50.76 8 2 ½” 119 8

2” 84 8 3” 184 8
[63] [317] [2.44] [90] [698] [2.44]
NOTE – System design should allow a maximum of 8-ft/sec [2.44 meters/sec] water velocity in residential pool or spa
piping. It is recommended that a minimum length of piping, equivalent to 10 pipe diameters, be used between the
pump suction inlet and any plumbing fittings.
Plumbing
Use Teflon tape to seal threaded connections on molded plastic components. All plastic fittings must be new or
thoroughly cleaned before use. NOTE - Do NOT use Plumber’s Pipe Dope as it may cause cracking of the plastic
components.
When applying Teflon tape to plastic threads, wrap the entire threaded portion of the male fitting with one to two
layers of tape. Wind the tape clockwise as you face the open end of the fitting, beginning at the end of the fitting.
The pump suction and outlet ports have molded-in thread stops. Do NOT attempt to force hose connector fitting
past this stop. It is only necessary to tighten fittings enough to prevent leakage. Tighten fitting by hand and then
use a tool to engage fitting an additional 1 ½ turns. Use care when using Teflon tape as friction is reduced
considerably; do NOT over-tighten fitting or you may cause damage. If leaks occur, remove connector, clean off
old Teflon tape, re-wrap with one to two additional layers of Teflon tape, and re-install connector.
Fittings
Fittings restrict flow. For better efficiency, use the fewest possible fittings. Avoid fittings that could cause an air
trap. Use two or more suction outlets per pump installed in accordance with latest ASME, APSP Standards and CPSC
guidelines, follow all National, State, and Local codes applicable.
Electrical
NOTICE – All wiring must be done by a licensed electrician and must conform to all local and national codes
and regulations.
WARNING – Risk of Electric Shock. Before working on any electrical equipment, turn off power supply to the
equipment.
WARNING – Fire Hazard. Match supply voltage to motor nameplate voltage.
Insure that the electrical supply available agrees with the motor’s voltage, phase, and cycle, and that the wire size is
adequate for the HP (kW) rating and distance from the power source. NOTE - All electrical wiring MUST be
performed by a licensed electrician, and MUST conform to local codes and NEC regulations
