months, then every six
months to one year
thereafter.
SPD check
(1) Annual inspection of cable connection to ensure that they are in
good mechanical working order.

Every 6 months to 1 year
Fuse check
(1) Annual inspection of cable connection to ensure that they are in
good mechanical working order.
(2) Check the operating parameters (especially voltage and insulation).
Every 6 months to 1 year
Battery
maintenance
(1) Perform normal charging and discharging operations on the battery
system to check whether there are any abnormalities in the operating
status of the battery, and to check whether the battery system indicator
status is normal.

Aerosol fire
extinguisher
inspection
When the fire extinguishing equipment is in normal working condition, it
is necessary to check the starting device (JR10 starter box, etc.) to make
sure that the line is normal.
The fire extinguishing equipment is maintenance-free for its own validity
period.
Officially run for six
months, then every six
months to one year
thereafter.
Air conditioner
maintenance
(1) Check whether the temperature of the air outlet is close to the cooling
setting value, ±2℃.
(2) Check the degree of dust at the air inlet and outlet. And use a
compressed air machine to clean and treat the dust at the air conditioner
inlet and outlet.
Ranges from quarterly,
semi-annually or once a
year (depending on the
dust content of the
environment in which it
is used).
Display
maintenance
(1) Check the display for water ingress and see if the display shows
normally without color change.
(2) Test the display to see if it responds normally to switching and
selecting content.
