Dears,
I have faced a problem on a Hitachi VRF Set Free FS5. In fact, the problem is just one cassette RCI model (RCI015A3F - RCI0409).
That cassette is not working well when the outside temperature is high (around 32° / 34°C). Even if the operating temperature has been set to 19°C, the temperature inside the room does not reach even 24° / 25°C. The situation becomes worse if the we switch on the following cassettes from the same refrigerant line. It seems that the cassette`s performance has been disturbed by some unknown reason.
When the outside temperature is not so high, no matter how many cassettes form that refrigerant line are working at the same time, the temperature inside the room reachs the desired value.
The refrigerant`s pressures were check and both are OK.
What may causes disturbs on cassette`s performance?
What may causes problems similar that?
What should I check or test?
I thank in advance for any help.
Cheers,
Rafael
