8-3 Storage
This product is best placed in the original packaging before installation. If
the machine is not used for the time being, in order to make the product meet
the warranty of the company and future maintenance, please pay attention to
the following matters during storage.
：
•
Avoid storage in environments containing corrosive gases and liquids.
•
Long-term storage will lead to deterioration of electrolytic capacitors. It
is best to ensure that the power is turned on within 2 years, and the
power-on time is not less than 5 hours.
•
It is best to store it properly on a shelf or counter top.
8-4 Inverter warranty
The company will provide repair services in the following cases:
：
If it fails or is damaged under normal use conditions
：
1) During the warranty period (from within 18 months after delivery or within 1
year of delivery to the end user), the company provides free repairs.
Even within the warranty period, a certain maintenance cost should be
charged for the failure caused by the following reasons
：
1) Failures caused by failure to use the operating manual or beyond the
standard.
2) If it is more than 18 months, reasonable maintenance fees will be charged.
2) Failure caused by self-repair and modification without permission.
3) Failures caused by improper storage and improper handling.
4) The fault caused when the inverter is used for abnormal functions.
5) Machine damage due to fire, salt erosion, gas corrosion, earthquake,
storm, flood, lightning, voltage abnormality or other force majeure.
Even if the warranty period is exceeded, the company also provides
lifetime paid repair service.
