Motors fitted with grease nipples should be lubricated with a high- temperature lithium-based grease, see the instructions on the fan cover of GRUNDFOS motors. In the case of seasonal operation (motor is idle for more than 6 months of the year), it is recommended to grease the motor when the pump is taken out of operation. -
Page 28: Operating And Fault Indications
9. Operating and fault indications The two indicator lights (LED) on the front cover of PFU 2000/ PMU 2000 indicate pump operation (green) and/or fault (red). Two external indicator lights (LED) can be connected instead of the two indicator lights (LED) on the front cover. The function of the indicator lights (LED) and the operating and fault signal outputs appears from the table below. -
