7) Repeat the operation with water
8) Connect again the peristaltic pump to the system
TROUBLE-SHOOTING COMMON TO RACER SERENITY
Mechanical faults
As the system is quite robust there are no apparent mechanical problems. Occasionally there might be a loss of liquid from the
nipple because the tube nut has loosened, or more simply the peristaltic tube has broken. In this case they have to be replaced.
After repair, the peristaltic pump will need to be cleaned of additive residues which can damage the pump casing.
PERISTALTIC TURNING BUT THE ADDITIVE IS NOT INJECTED
1) Check the integrity of peristaltic tube. Should the tube be swollen, check tube material against our chemical
2) Check clogging of the filter.
3) Check clogging of the injection valve.
Electrical faults
THE PUMP DOES NOT MEASURE CORRECTLY
1) Check the calibration of controller
2) Check the efficacy of the electrode
THE PERISTALTIC PUMP FAIL TO DOSE
1) Make sure the "Setpoint" has been correctly set
2) Make sure the "ACID/ALK" jumper is in the right position, i.e. that it concords with the required dosing.
IN CASE THE ADDITIVE LEVEL IS BELOW THE LEVEL PROBE AND LEVEL ALARM IS STILL OFF
Check the level switch connection, short circuit poles connector (Chapter SERVICE CONNECTOR WIRING DIAGRAMS AND
FUNCTIONS) in case the alarm is on, replace the switch; if the alarm is off, contact Manufacturer, Customer Service, Delear or
Distributor.
Attention: when removing the perstaltic pump from the plant, use great care in detaching the delivery hose from the
connector nipple, because it could contain some residual additive.
