I got called out to a wall unit in a office the other day that keeps leaking.
One of the other engineers had already been out to it and thought he had fixed it but he hadn't.
I cant remember the model of the wall unit but its 5 or 6 years old on r407c and about a 5kw.
The coil is an upside down "V" shape and after stripping the unit down to get at the coil i could see water was dripping from the top of the coil (the point of the"V") and onto the spinning fan, which was causing water droplets to fall down and drip out of the unit where the air off comes out.
I checked the unit was level, cleaned the coil throughly (even though it was clean), re-fixed the unit to the wall as it was hanging off by 1/2 inch, tried turning the fan speed down and checked the fan wasn't blocked but nothing seemed to work.
The water from the coil should run into the tray either side of the coil but the top of the coil just drips vertically down onto the fan.:rolleyes:
Has anyone come across this before?
