3.2. Pump Mounting
Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base
with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be 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 valves in suction and discharge piping.
• Be protected from excess moisture and flooding.
• Allow adequate access for servicing pump and piping.

MAXIMUM RECOMMENDED SYSTEM FLOW RATE BY PIPE SIZE
Pipe Size
in. [mm]
Maximum Flow Rate
GPM [LPM]
Minimum Suction Pipe
Length* in. [mm]
1” [32] 20 [75] 5” [127]
1 ¼” [40] 30 [110] 6 ¼” [159]
1 ½” [50] 45 [170] 7 ½” [190]
2” [63] 80 [300] 10” [254]
2 ½” [75] 110 [415] 12 ½” [317]
3” [90] 160 [600] 15” [381]
* Note: It is recommended that a minimum length of straight piping (shown as “L” in above diagram), equivalent to 5
pipe size diameters, be used between the pump suction inlet and any plumbing fittings (elbows, valves, etc.).
3.4. Plumbing
1. 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.
2. 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.
3. Fittings (elbows, tees, valves, etc.) restrict flow. For better efficiency, use the fewest possible fittings. Avoid
fittings that could cause an air trap. Pool and spa fittings MUST conform to the International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
3.5. Electrical
WARNING – All electrical wiring MUST conform to local codes, regulations, and the National Electric
Code (NEC).
WARNING – Ground and bond pump before connecting to electrical power supply. Failure to ground
and bond pump can cause serious or fatal electrical shock hazard. Do NOT ground to a gas supply line. To
avoid dangerous or fatal electrical shock, turn OFF power to pump before working on electrical connections.
Fire Hazard - match supply voltage to pump nameplate voltage. Insure that the electrical supply available
agrees with the pump’s voltage, phase, and cycle, and that the wire size is adequate for the amps rating and
distance from the power source. Use copper conductors only.
