CAUTION
cause improper operation.
Wipe dirt and water off the Drive Shaft from the bottom up (Fig. 55).
Insert the replacement Irrigation Pump straight into the Drive Shaft in a
slow and gentle manner to prevent damaging the pump rollers.
After replacing the Irrigation Pump, run this product for about 10
seconds with Irrigation Mode set to Bottle and Irrigation Volume set to
maximum so the Irrigation Tube adapts to the new Pump.
Ensure there are no kinks or twists in the Irrigation tube. If tube is set
incorrectly, Irrigation Water may not be supplied.
Make sure that the Tube is not caught under the Irrigation Pump Cover
when closing the Irrigation Pump Cover.
Only use the dedicated Irrigation Pump for Varios Combi Pro. Other
pumps cannot be used.
NOTICE Clean the Drive Shaft periodically with a cloth soaked in alcohol. Debris on Drive Shaft may cause incorrect pump operation.
The pump is a wear item. If the irrigation volume decreases markedly, replace the pump.
