14. Troubleshooting

This chapter shows two tables. The first one shows the warning messages that the equipment can emit, their causes
and the corrective actions on them. As a general prevention measure, it is recommended to follow the corresponding
actions once a warning is activated. The second table collects most of the unforeseen situations that may require
intervention, their causes and the corrective actions on them.

14.1 Warnings

Warning
The equipment emits warnings through a symbol and an acoustic signal. Pressing any key deactivates the acoustic
signal.
Warning- Replace
pretreatment.
Warning- Replace
deionization resin.
Warning-
Water cut
Warning- Conductivity probe

14.2 Problems

Problem
The screen light or the menu
does not work.
The equipment produces no
water or produces very little
water.
The conductivity of the final water
is high.
Cause
the The working hours of the
equipment reached the working
hours set point.
the The conductivity of the Type II
water exceeded the conductivity
set point.
The feed water is interrupted
Conductivity probe
measuring correctly.
Cause
The equipment does not receive
electrical power.
Defective electrical component.
Water is not being supplied to the
equipment.
Feed water pressure < 3 bar
Erroneous hydraulic connections.
The resin cartridges may be
exhausted.
Corrective actions
Change the pretreatment cartridges [1] and [2].
Follow the instructions in Section 11.1.
Change the resin cartridges [3] and [4]. Follow the
instructions in Section 11.2.
Check that water is being supplied to the equipment.
Change the pretreatment if it is blocked.
is not Contact the Technical Assistance Service (see
contact information in Section 0.3).
Corrective actions
Disconnect the equipment. First disconnect the plug-
in and then disconnect the transformer from the
electrical network.
Check the electrical connections: Connection to the
electrical network, to the transformer and to the
electronic board.
Check that water is being supplied to the equipment.
See recommended actions described in Warning-
Water cut.
Check the inlet pressure: The lower the pressure,
the lower the performance of the equipment.
Check the hydraulic connections.
Check that the tube that connects the tank to the
equipment is not blocked
Check that the rejection tube is not blocked
If no deviations are observed after checking all the
above, the lower production may be due to the
exhaustion of the reverse osmosis membrane, See
recommended actions in problem The resin lasts a
short time.
Check the switch level connection.
Check that water is coming out of the rejection tube.
Change the resin cartridges [3] and [4]. Follow the
instructions in Section 11.2.
