Hi Kris, Thank you for your question, please be advised this Standard specifies design requirements for natural ventilation systems and mechanical air-handling systems that ventilate enclosures, and sets minimum requirements for the ventilation of enclosures. This standard does not apply to just the air conditioner and the ventilation system needs to be looked at. For any further questions please don't hesitate to contact Fujitsu Technical support Tel: 1300 364 484 and they will do their best to assist you.

Hi , i would like to know why one of the two blower fan motor blow less air than the other blower in the roof internal unit on cooling auto mode.i have also notice the fan blowing less air is more likely running on low speed when the other blower fan motor blowing air on higher speed. Is it suppose to run the same speed on both blower fan motors at the same time? You help to this answer would be highly appreciated .Thanks Salim

Hi Salim, in regards to your question, The indoor unit has two fan motors and two fan blades. If there is a problem with either of these, the fan will produce less air on one side. If you are referring to the actual outlets in your rooms, depending on how the system is designed will dictate how much air comes out of each outlet. For example, if there are 5 outlets on one side of the ducted unit and 7 on the other, the amount of air coming out of the outlets where there are 5 outlets will be more compared to the side that has 7.
If you would like to discuss this further please don't hesitate to contact our technical support team who will be happy to chat through your questions Tel: 1300 364 484.
