Hi guys,
I`m commissioniing a Toshiba VRF system with five cassetess and seven high wall units. The system has been set up ok with the help of the Toshiba technical help line but two of the cassette`s fans are very noisy even at minimum speeds. A phone conversation cannot be easily made sitting near them and the draught from them is uncomfortable. I`ve checked the ceiling setting and all`s ok there. I spoke to Toshiba and they confirmed that the settings were right for the ceiling in question. But here`s the strange thing two of the othere cassettes are a more powerful model and they are very quiet. The models giving the problem are MMU-AP0362H.
Toshiba have siad it`s not possible to reduce the speed any more as to do so would could freezing of the evaporator, but as say the larger ones are virtually silent with no freezing problems .
I`m just wondering do any of you guys know of a way to slow the fans down.
Cheers guys,
Glenn
