9. Position the tubing and fittings deep into the pump
head body.
10. Using Manual Mode, activate the peristaltic pump for 1
second and insert one roller at a time in the free
position (where the roller is not in contact with the
tubing). Repeat for the 3 rollers.
11. Replace the Plexiglas pump cover. Attach the cover
with the 3 screws TSPEI M3x8 using an Allen Key.
12. Using Manual mode activate the peristaltic pump for
180 seconds (3 minutes) to settle the tubing into
position.
13. Reconnect the outlet tubing to the peristaltic pump fitting.
14. Reconnect the reagent intake tubing to the peristaltic pump fitting.
15. Using Manual mode activate the peristaltic pump for 45 seconds to prime the pump.
16. Repeat the above steps for each additional pump for which it is necessary.
Maintenance frequency for tubing replacement is 70 working hours. To calculate the maintenance
frequency for a pump, simply determine the number of analysis cycles per day and the reagent's dose
time for each analysis cycle.
Example: 4 analysis cycles per hour (i.e. 96 analysis cycles per day), Dose time 1 5 seconds for each
analysis cycle. Working hours per day = (96 cycles/day)(15 sec) / 3600 sec/hour = 0.4 hours / day
Maintenance frequency = 70 hours / 0.4 hours / day = 175 days
