Operation and maintenance 8.1 Lubrication and maintenance Pumps installed in accordance with these instructions require very little maintenance. The motor ball bearings are grease-packed and sealed for life. No further lubrication is necessary. 8.2 Filters Chip trays, filters, etc. should be cleaned at regular intervals to ensure a correct flow of liquid. This will also increase the pump life. 8.3 Periodic checks Make the following checks at regular intervals, depending on the conditions and time of operation. ? Check the quantity of liquid and operating pressure. ? Check that there are no leaks. ? Check that the motor is not overheating. ? Check the tripping of the motor-protective circuit breaker. ? Check that all control devices are operating satisfactorily. If the above checks do not reveal any abnormal operating details, no further checks are necessary. Should any faults be found, see section 10. Fault finding. 9. Service A contaminated pump must not be sent to Grundfos for service until Grundfos has received all necessary details about the pumped liquid, etc. Otherwise Grundfos can refuse to accept the pump for service.
