Operate the Indoor Unit in “Fan” mode for at least 2 hours, in order to remove residual humidity
inside it.
Disconnect the system by switching over main switch to “OFF”.
Remove batteries from infrared Remote Controller, in order to avoid that eventual acid leakage
might damage the contacts inside the battery case.
Clean the Indoor Unit, the frontal panel and air filters as it has been previously indicated.
Take care to prevent dust and/or foreign metters from entering the Indoor Unit, by protecting it
properly by a nylon covering.
Please check also visually the general state of wiring and refrigerant connections.
Remove the eventual protective covering on Indoor Unit.
Check if all air filters are installed on Indoor Unit: air filters must be well clean and not
damaged.
Check if frontal panel is properly installed in closing position.
Replace batteries in infrared Remote Controller, and check if contacts are not damaged
(eventual oxidation, etc.) inside the battery case.
Check if no objects and/or foreign matters might obstruct air inlet and/or air outlet of Indoor
Unit.
Connect the system to power supply by switching over main switch to “ON”, at least 6 hours
before starting the system itself.
