the retailer.)
 After completing the installation, always carry out a functional test and provide the
instructions on how to operate the air conditioner to the user.
 Do not use the air conditioner in environments with hazardous substances or close to
equipment that release free flames to avoid the occurrence of fires, explosions or injuries.
