Inspection And Replacement Of Wear Parts; Storage And Warranty; Disposal - Grundfos RSI Series Installation And Operating Instructions Manual

7.2 Inspection and replacement of wear
parts
7.2.1 Cooling fan
Inverters are equipped with cooling fans. The
cooling fan's service life is about 15000 hours. If the
fan generates abnormal noise or produces
vibrations, replace it immediately. The cooling fan
will start automatically when the internal temperature
of inverter is higher than 55 °C and stop when the
internal temperature of inverter is lower than 45 °C.

7.3 Storage and warranty

7.3.1 Storage
If the product is stored for a long time after
purchasing, comply with the following requirements:
1. Avoid placing the inverter in high-temperature or
humid areas or areas with vibration and metal
dust. Ensure ventilation.
2. The performance of the capacitor inside the
inverter can be reduced if the equipment is not
used for a long period of time. It is thus
necessary to start up the equipment every two
years to restore the performance of the capacitor
and inspect the inverter function at the same
time. The voltage must be increased gradually
through a DC power supply with power-on time
being not less than 5 hours.
7.3.2 Warranty
The following situations are not covered by the
warranty:
• Faults caused by failure to comply with this
manual or standard specifications.
• Faults caused by self-repairing and modification
without permission.
• Faults caused by poor storage and maintenance.
• Faults caused by abnormal use of the inverter.
• Damage caused by fire, salt corrosion, gas
corrosion, earthquake, storm, flooding, lightning,
abnormal voltage or other force majeure
situations.
