General Information
This manual has been constructed to offer the adequate information on the installation,
operation and maintenance of our spa pool pumps. We suggest you read it thoroughly for
correct installation and optimum performance of the pump.
These are single-stage centrifugal pumps designed to operate with hydro-massage
equipment on spa pools. They should not be used for any other purpose without first
consulting your SpaNET dealer or Spa Net Customer Service. The pumps are designed to
o
operate with clean water at a maximum water temperature of 50 C.
Installation Location
ŸThe pump should be located as close to the water as practical keeping the suction pipe
of the pump as short as possible.
ŸThe pump should be installed on a level firm base in a well drained position, high
enough to prevent any flooding and be fixed to the base by screws or nuts.
ŸIt is the installer’s responsibility to position the pump so that the ratings label can be
easily read for service, and in a location where water will not drip onto the motor.
ŸThe pump will get hot during operation, to ensure sufficient cooling the minimum
distance between the motor of the pump and any surrounding structure should not be
less than 30mm.
Pipe Connection
ŸThe suction pipes should have a diameter equal to or larger than that of the discharge
pipes, to avoid loss of head and improve pump efficiency.
ŸTwo suction inlets must be provided into each pump to avoid suction entrapment.
ŸSuction & discharge pipes should have a gentle slope of at least 2% to assist purging air.

Pipe Connection (continued)
ŸThe maximum inlet water pressure ≤ 0.15MPa
ŸA set of mac unions are provided for connecting the pump to the pipe work. The circ
pump series are designed to accept 40mm PVC pressure pipe, the boost pump series
accept 50mm PVC pressure pipe.
ŸThe use of PVC pressure pipe smaller than 40mm (circ series) or 50mm (boost series) is
not recommended.
ŸThe pipe work should be adequately supported and secured to the mac union by glueing
the pipe to the inside of the union tail.
ŸMac union lock nuts are to be hand tightened. Do not use sealant, silicones or glues on
lock nuts.
Power Connection
ŸSpaNET SmartFLO pumps are suitable for connection to a nominal 240V AC / 50Hz power
supply and are supplied with a flexible lead and AMP plug to facilitate easy connectivity
to a SpaNET spa controller.
ŸThis pump should be supplied through a residual current device (RCD) having a rated
residual operating current not exceeding 30mA.
ŸAll SmartFLO pump motors have built-in thermal protection.
ŸWires serving as equipotentional bonding conductors shall have a cross sectional area
2 2
between 2.5mm and 6mm and be equipped with suitable terminal receptacles.
ŸExtension power cords are unsafe around spas and pools and should not be used.
Steps prior to starting pump
Before attempting to use the pump you must confirm that:
ŸThe pump has been installed in a safe and dry environment.
ŸThe enclosure that houses the pump has sufficient drainage in the event of leakage
ŸVerify that the pump shaft turns freely.
ŸCheck the mains voltage and frequency of power supply match ratings label of pump.
ŸThe pipe work is correctly supported and barrel unions are tight and sealed.
ŸThe spa pool water level is at the correct height and the pump has been primed.
ŸAll isolating valves are open and there is nothing preventing flow of water into and out of
the pump.
WARNING: The pump should never be operated dry!
Running the pump without water may damage the mechanical seal causing the pump
to leak. Damage to seals from dry running of the pump is NOT covered by warranty.
!

Pump Operation
ŸTo assist in priming, the pump should always be located below the water level of the spa.
ŸFollow tips in “Steps prior to starting pump” before switching pump on.
ŸConnect the pump to spa controller or power supply and turn on.
ŸAllow the pump to run to expel any air that may be trapped in the pump wet end.
ŸIf 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
ŸIf 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
ŸEnsure that suction covers are securely attached and not damaged or broken. Do not
operate pump if suction covers are broken to avoid entrapment.
ŸRemove any debris or obstructions that may build up on suction covers.
ŸEnsure filters are regularly cleaned and soaked in filter cartridge cleaner every 4-6 weeks.
ŸCheck water balance and sanitiser levels on a regular basis
ŸEvery 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.
ŸIf 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.
!

Troubleshooting
Pump not pumping properly / water flow reduced
ŸPump is not primed and wet end full of air - attempt to reprime pump and/or bleed air
from pump by loosening barrel unions.
ŸPump is starving for water - check the valves to the pump are open fully, check water
level - top up if necessary, check spa filter cartridges and clean if required.
ŸThere are air leaks in the suction line - check all pipe work and tighten mac unions to
eliminate leaks.
ŸA leaking mechanical seal may also cause problems with the pump bearings and make it
difficult for the pump shaft to rotate - water or chemical calcification will be evident
underneath the pump if the seal has been leaking. Service pump in this case.
ŸImpeller is worn out - service pump and replace impeller
Pump does not start
ŸThe power cord is not connected - check power cable. Where the pump is connected to a
spa controller check the pump is connected to the correct pump socket, check dip
switches are set correctly, and check controller touch pad to confirm pump is active.
ŸLow voltage - check there is proper voltage applied to the pump and avoid using
extension cables.
ŸBlockage in pipe work or pump wet end in preventing the pump from rotating - inspect
for foreign debris and remove where required.
ŸMotor has overheated and thermal cut-out has activated - the pump motor has built in
thermal protection which activates when the motor becomes too hot and automatically
resets after the motor has cooled. Determine the cause of overheating and rectify - check
motor has adequate ventilation, fan is not blocked and can spin freely.
ŸMotor has seized bearings due to a leaking mechanical seal over an extended period of
time - get bearing and seal service if possible, if not replace pump.
If you are unable to resolve any installation or operating issues with your SmartFLO pump
you should contact the reseller you purchased the pump from or your closest authorised
SpaNET repair technician or spa dealer. If you require any further assistance contact the
