TROUBLESHOOTING
Given the sturdiness of the product, actual mechanical failures do not occur. However liquid may at times leak from a
loose fitting or ring nut, or simply if the delivery pipe bursts. Rarely, any leaks may be caused by the breakage of the diaphragm
or by the wear of the diaphragm sealing gasket. In this case, these components must be replaced by disassembling the four
screws of the pump body. When reassembling these screws they must be tightened evenly with the correct tightening torque.
Once the leak has been repaired, clean the metering pump of any additive residues which by stagnating may chemically attack
the pump chassis.
Any work or repairs inside the equipment must be carried out by qualified and authorised personnel.
In the event of maintenance and/or technical intervention, always make sure the pump is disconnected from the electrical
mains and that protective clothing and equipment (gloves and safety goggles) are worn.
FAULT
The pump does not dispense
The electronic part does not transmit pulses
to the magnet
No LED on
LED on, no strokes in the pump.
Irregular strokes in the pump
Infiltration detected
The pump runs but does not draw liquid
ROUTINE MAINTENANCE TABLE
2 weeks
1 month 2 months 3 months 4 months 6 months 12 months
Check valve mounted incorrectly or worn: mount it correctly or replace it by following the
routine maintenance recommendations;
Diaphragm worn: replace it;
Burnt fuse on magnet: replace it (check the resistance of the magnet);
Electromagnet burnt: replace it.
Circuit board burnt due to overvoltage, lack of earthing, etc.: replace the board.
Check that the pump is correctly powered (socket and plug): if the pump remains inactive, contact
our Service Centres.
Press the START/STOP button; should the problem persist, check that the external stop is not
activated or that the pump is in stand-by due to operation of the level probe.
Check that the power supply voltage value is within the indicated limits.
a)
Using the head gasket
Unscrew the four screws of the head and make sure the O-Ring of the pump body is in good
condition and the diaphragm is correctly screwed, otherwise replace them. Also make sure
the infiltration has not damaged the board or the magnet.
b) Using the control panel
Observe the board and check the condition of the electrical components and the printed
circuit tracks. Check the electrical resistance of the electromagnet.
Should one of the two components be damaged, proceed with its replacement. Make sure all
components that tighten the delivery pipe are mounted correctly or are not damaged. Also
replace the screen printing that allowed the infiltration.
Disassemble the suction and delivery valves, clean them and reassemble them in the same
position.
Check the status of filter clogging and of the injection valve.
