Hi Guys!

I've got a Fujustu 4kw R22 wall mount unit, and it keeps dripping condensate from the middle of the unit.
Drain pipe is clear, unit is horribly installed, but level-ish.
No frost on the lines so I guess the charge is ok. The environment it is in isn't excessively humid, but the air is oily and there are mineral oil deposits all over the unit!
I suspect that the condensate gutter may have fractured as the oil can rot the plastic. Due to the amount of oil present, I doubt repair will be effective. Can this part be replaced... or it it bad news for my customer? Unit is around 6 years old!

Any thoughts?
