Pump Operation
Ÿ
To assist in priming, the pump should always be located below the water level of the spa.
Ÿ
Follow tips in “Steps prior to starting pump” before switching pump on.
Ÿ
Connect the pump to spa controller or power supply and turn on.
Ÿ
Allow the pump to run to expel any air that may be trapped in the pump wet end.
Ÿ
If full prime is not achieved within 30-40 seconds (full prime will be demonstrated by a
strong flow of water returning to the spa), switch off the pump and wait for 30 seconds
before trying to operate the pump again
Ÿ
If the pump does not fully prime after 3 attempts, the pump should be switched off and
pump should be bled of air manually by slightly loosening barrel unions to expel the air,
and after the air is bled the pump can be operated again.
Water Chemistry Maintenance
Avoiding over sanitising and maintaining balanced water chemistry is very important to the
life span of your SmartFLO pump. It is your responsibility to regularly check and maintain the
chemical water balance of the spa pool (at least once a week), to ensure it remains within
reasonable pH and Alkaline limits. The pump is designed to be used with balanced spa water
with a pH level of between 7.2 - 7.8 pH, and is to be regularly treated with a sanitising agent
with a level not exceeding 3PPM. Please visit your local pool and spa shop for regular water
tests and for further guidance regarding water chemistry.
NOTE:
Do not add raw undiluted chemicals directly to the spa filter area or near the
pump suction drains. Adding undiluted chemicals may damage the pump and
mechanical seal and void warranty.
Maintenance & Cleaning
Ÿ
Ensure that suction covers are securely attached and not damaged or broken. Do not
operate pump if suction covers are broken to avoid entrapment.
Ÿ
Remove any debris or obstructions that may build up on suction covers.
Ÿ
Ensure filters are regularly cleaned and soaked in filter cartridge cleaner every 4-6 weeks.
Ÿ
Check water balance and sanitiser levels on a regular basis
Ÿ
Every 12-18 months inspect pump for leaking mechanical seal. If seal is leaking ensure
pump is serviced and mechanical seal is replaced. If the seal is leaking and it is not
replaced, the leak will eventually cause the bearings to rust and seize the motor.
Ÿ
If the pump is to be idle for a long period of time, it is recommended to disconnect both
suction and discharge barrel unions, drain the water from the pump wet end and leave
unions disconnected so the pump is dry and well ventilated.
