Do not perform compulsory operation in any way, because it is very dangerous if the protection device is not
active.
Perform trial run only after all installations are finished.
Confirm the following issues before trial operation:
Install the remote controller holder as required by the user. The holder must be installed in a location
suitable for transmitting the signals of the remote controller to the indoor unit.
Use the remote controller or wired controller to let the air conditioner run in the cooling mode. Inspect the
following items according to the operation manual. If any fault occurs, remove the fault first.
Check the indoor unit:
Whether any vibration or abnormal sound occurs during the operation.
Whether the air, noise and condensate generated by the unit affect the neighbors.
Whether any refrigerant is leaked.
Check whether the connective copper pipes and drain pipes generate condensate due to loose
wrapping.
Open the air inlet grille of indoor unit to check whether any penetration or leak of water occurs,
especially at the drain stopper.
