11. Inspection and maintenance
Air conditioning units including AE-200/AE-50 controllers may be damaged after long use, resulting in a performance
drop or the units becoming a safety hazard. To use them safely and maximize their lives, it is recommended that a
maintenance contract with a dealer or qualified personnel be signed. If the contract is signed, service technicians
will periodically inspect the units to identify any damage at an early stage, and take appropriate measures.
