circuit.

FlowXtreme 48SM-I & 48SM-II are In Ground Pumps and MUST be permanently connected to an appropriate electrical

circuit. If other lights or appliances are also on the same circuit, be sure to add their amp loads before calculating wire and

circuit breaker sizes. Use the load circuit breaker as the Master On-Off switch.

Always Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short circuit to ground and disconnect

power before it becomes dangerous to pool users. For size of GFCI required and test procedures for GFCI, see

manufacturer’s instructions. In case of a power outage, check GFCI for tripping, which will prevent normal pump operation.

Reset if necessary.

NOTE - If you do not use conduit when wiring motor, be sure to seal wire opening on the back end of the motor to

prevent dirt, bugs, etc., from entering.

NOTE – See additional wiring information and wiring diagrams in the Section #7, Technical Data for 48SM-I &

48SM-II Pumps

Section #4, Start-Up & Operation

Prior to Start-Up

Notice: If it is necessary to perform a pressure test, prior to initial use to ensure pump is functioning properly, then the

following criteria should be maintained for this test:

1. Have a professional perform this test.

2. Ensure all pump and system components are sealed properly to prevent leaks.

3. Remove any trapped air in the system by fully opening filter manual air relief valve until a steady stream of water is

discharged.

4. Allow no more than 40 psi (276 kPa) at a water temperature no higher than 100° F (38° C).

5. Run pressure test for no longer than 24 hours. Immediately inspect all parts to verify they are intact and functioning

properly.

Fill strainer housing with water to suction pipe level.

NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and lubricant for the mechanical shaft

seal.

WARNING – If pump is being pressure tested (40 PSI MAXIMUM), be sure pressure has been released, using the

filter manual air relief valve, before removing strainer cover.

CAUTION – NEVER run pump dry. Running pump dry may damage seals, causing leakage, flooding, and voids

warranty. Fill strainer housing with water before starting motor.

ATTENTION – Do NOT add chemicals to pool/spa system through the skimmer (if pool is so equipped) or directly

in front of pump suction. Adding undiluted chemicals may damage pump and voids warranty.

ATTENTION – Before removing strainer cover:

1. STOP PUMP before proceeding.

2. CLOSE VALVES in suction and outlet pipes.

3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner’s

manual for more detail.
