Frequently Asked Questions:
What size piping does The Max Flo II have?
– The Max Flo II pump has 2 inch intake and discharge.
What is the voltage on The Max Flo II pump?
– The Max-Flo II pump is a 115/230 dual voltage. It comes factory wired for 230 volts, But can be rewired to 115.
How long should I run my pump for?
– You should run your pump for at least 8 hours a day. Although the Max-Flo II pump is designed to be run 24 hours a day 7 days a week.
Is the Max-Flo II pump self-priming?
– Yes, the pump is a self-priming pump (suction lift 8 ft above water level).
Is this a dual speed pump?
– No, this is a single speed pump.

Troubleshooting:
- Motor won't start:
- Check for improper or loose connections, open switches or relays, blown circuit breakers or fuses.
- Manually check rotation of motor shaft for free movement and lack of obstruction
- Motor cuts out – check for:
- Wiring, loose connections, etc.
- Low voltage at motor (frequently caused by undersized wiring).
- Binding and overload. (Amperage reading)
- Motor hums, but does not start – check for:
- Governor stuck in open position.
- Open capacitor.
- Motor cuts out – check for:
- Wiring, loose connections, etc.
- Low voltage at motor (frequently caused by undersized wiring).
- Binding and overload. (Amperage reading)
- Pump won’t prime:
- Make sure pump/strainer housing is filled with water and that cover gasket is clean and properly seated. Tighten hand nuts.
- Make sure all suction and discharge valves are open and unobstructed, and that pool water level is above all suction openings.
- Block off suction as close to pump as possible and determine if pump will develop a vacuum.
- If pump does not develop a vacuum and pump has sufficient "priming water".
- Tighten all bolts and fittings on suction side
- Check voltage to make sure pump is up to speed.
- Open pump and check for clogging or obstruction.
- Remove and replace shaft seal.
- If pump develops a vacuum, check for blocked suction line or strainer, or air leak in suction piping.
- Low Flow – Generally, check for:
- Clogged or restricted strainer or suction line; undersized pool piping.
- Plugged or restricted discharge line of filter (high discharge gauge reading).
- Air leak in suction (bubbles issuing from return fittings).
- Pump operation underspeed (low voltage).
- Plugged or restricted impeller.
- Noisy Pump – check for:
- Air leak in suction causing rumbling in pump.
- Cavitation due to restricted or undersized suction line and unrestricted discharge lines. Correct suction condition or throttle discharge lines, if practical.
- Vibration due to improper mounting, etc.
- Foreign matter in pump housing.
- Motor bearings made unserviceable by wear, rust, or continual overheatings.
