7.2 Installation of the Outdoor Unit 

Firstly select the installation site and fix the outdoor 
unit. If it needs to be fixed onto the wall, make sure 
that the wall and the supporting rack is strong enough 
to hold the weight of the appliance.

Release the set screws of the electric cover, 
remove the electric cover (if the valve cover  is 
there either, please release it).          
Connect the indoor unit  wiring  to the outdoor unit 
panel according to the electric wiring diagrams. 
Be sure to make  each wire allowing 10cm longer 
than the required length for wiring.
Ground the unit following local electrical 
regulations.
Check the wiring with the wiring diagrams and 
make sure it's well connected. Fix the  wiring with 
clips and reinstall the electric cover.
