3.6 Peristaltic pump
3.6.1 Test / priming the peristaltic pump
After installation, we recommend testing the peristaltic pump for the module and priming it (system normally self-priming).
• Before testing the peristaltic pump, ensure that all pH minus suction and injection pipes are correctly connected.
•
Always use appropriate safety equipment when handling chemical products.
•
Switch on the power pack (
button).
•
Press
or
, then use the
or
keys to display “CALIB. PH" or "CALIB. PH\ACL", then press
or
.
•
Use the
or
keys to display “TEST DOSAGE”.
• A warning will be displayed briefly, then press
or
to confirm starting the pump. The peristaltic pump will
operate for about 30 seconds and will stop automatically.
•
If the pump must be stopped immediately, press
or
.
• Confirm that the pump is primed (pH minus solution will be visible in the translucent pipes).
To prime the peristaltic pump more quickly, it may be necessary to repeat these steps several times, depending on
the length of the pH minus feed line.
3.6.2 Activating / deactivating the peristaltic pump
For safety reasons the peristaltic pump is not activated when delivered.
When the pH Link or Dual Link module is connected to the power pack, the peristaltic pump is programmed to start
approximately about 8 hours after being turned on. During this period, the default display on the LCD screen will show
“pH ---”.
To activate the peristaltic pump immediately:
•
Press
or
, then use the
or
keys to display “CALIB. PH” or “CALIB. PH\ACL" then
press
or
.
•
Use the
or
keys to reach the “DOSAGE OFF” (or “DOSAGE ON” line if the pump had previously been
activated).
•
Press
or
to activate the peristaltic pump (“DOSAGE ON”) or deactivate the peristaltic pump (“DOSAGE
OFF”).
4. Maintenance
4.1 Cleaning the sensor(s)
•
If the end of the sensor is coated with a greasy film (deposits of cosmetics, suntan lotion, etc.), soak it for a few minutes
in warm soapy water. Warning: do not use a detergent, dishwashing liquid is better.
•
If the end of the sensor is coated with limescale or if the above procedure is not enough, soak the sensor in a 10%
diluted solution of hydrochloric acid for a few minutes (wear the necessary safety equipment).
•
Rinse thoroughly with clean water.
•
Calibrate the sensor again (see § 3.3).
