TROUBLESHOOTING
Problem: The LCD display does not light up
Solution: Check PSU is plugged in correctly and turned on.
Problem: No liquid is coming through
Solution: Check direction of non-return valve and that the correct hose is in the liquid
(intake = right hand hosing)
Solution: Check priming of pump by pressing button D (Manual Feed/+)
Solution: Check pump head is correctly clipped onto the dosing pump
Solution: Check pump head for any signs of degradation
Solution: Check silicone tubing for any signs of degradation
Problem: Dosing pumps are not dosing on the hour
Solution: Each pump will run in order with approximately a 3 minute gap between doses. This
ensures your liquids will mix correctly and will help to stop precipitation of balling salts or
anionic or cationic trace elements joining together.
Solution: Check pump is selected to dose at that time.
Problem: There has been a power cut.
Solution: Settings are automatically saved in the event of a power cut. Once power is restored
the doser will dose at the next scheduled dosing time (it will not make up for any missed,
scheduled dosing times). For example, if the power goes off at 08:55 and comes back on at
09:55 and you have dosing times scheduled for 09:00 and 10:00 it will only dose once at 10:00
and will miss the 09:00 dose.
