Starting Up The Pump; Troubleshooting - Astralpool OPTIMA PRO NEXT Manual De Instalación

After about 800 hours of operation, tighten the bolts of the pump body by using a tightening torque of 3 Nm.
In making the hydraulic connections it is necessary to comply with the following instructions:
- The BOTTOM FILTER should be installed at a distance of about 5-10 cm from the bottom, in order to avoid clogging;
- The installation with the pump below the liquid level is recommended for pumps with very low flow rates. In particular when
dosing products that have a tendency to develop gases (ex: sodium hypochlorite, hydrazine, hydrogen peroxide...)
- If it is necessary to use tubes longer than those supplied with the installation kit, they must always have the same
dimensions as those supplied with the pump. If the DELIVERY PIPE is exposed to direct sunlight, it is recommended the
use of a black UV-resistant pipe;
- It is advisable for the INJECTION POINT to be placed higher than the pump or the tank.;
The INJECTION VALVE supplied with the pump, should always be installed at the end of the dosing-flow delivery line.

STARTING UP THE PUMP

Once you have checked all the above operations, you are ready to start the pump.
Priming
- Start the pump
- Open the priming coupling by turning the knob anticlockwise and wait for the liquid to flow out of the hose connected to it.
Once you are sure that the pump is completely filled with liquid you can close the coupling and the pump begins to dose.

TROUBLESHOOTING

PROBLEM
The pump is running regularly but the
dosage was interrupted
Insufficient flow rate
Irregular pump flow rate
The diaphragm is breaking
The pump does not turn on
EM00136320
Drilling template for the wall bracket
POSSIBLE CAUSE
The valves are clogged
Eccessive intake height
The liquid is too viscous
Leaky valves
The liquid is too viscous
Partial clogging of the
valves
Transparent PVC tube for
delivery
Excessive back pressure
Operation without liquid
The diaphragm is not fixed
properly
Insufficient power supply

SOLUTION
Clean the valves or replace them if it's not possible
to remove the deposits
Position the pump or the tank so as to reduce the
intake height
Reduce the intake height or use a pump with a
higher flow rate
Check the tightness of the nuts
Reduce the intake height or use a pump with a
higher flow rate
Clean the valves or replace them if it's not possible
to remove the deposits
Use the opaque PE tube for delivery
Check the system pressure. Check if the injection
valve is clogged. Check if there is a clogging
between the discharge valves and the injection
point.
Check the presence of the foot filter (valve)
If the diaphragm has been replaced, check its
proper tightening
Check if the values on the plate of the pump
correspond to those of the electrical network.
