Storage and warranty
9.2.1
Storage
If the product is stored for a long time after purchasing,
comply with the following requirements:
1. Avoid placing the pump controller in high-temperature or
humid areas or areas with vibration and metal dust. Ensure
ventilation.
2. The performance of the capacitor inside the pump
controller 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 pump controller 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.
9.2.2
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
pump controller.
• Damage caused by fire, salt corrosion, gas
corrosion,
earthquake, storm, flooding, lightning, abnormal voltage or
another force majeure situation.
