Evening men!!
Asked to look at a cassette on a vrv 2 pipe, which has been leaking water intermittently, when the indoor has been both off and on. The system feeds one big office which has 6 units, and this office which has 3. Both offices have their own controls. This particular unit is near the end of the pipe run.
The on site maintenance have witnessed the coil iced up, yet when I get to look at it, its ok,no water no ice.
Seem to remember that the eev never fully closes on vrv, could this cause an issue with the unit if other units are running? Also shouldn't the valve close fully ona freeze protection???
Help much appreciated ...
Thanks
