Morning people,

Quick question!

I have installed on a site a 2001 Mitsubishi City Multi on R407c.

Off that condenser I have an eight way box with 3 wall units and 5 cassette units, the compact type (not the 600x600, but not the standard size either, the size in between) a PLFY-P40VKM-E.

I've noticed on each of the 5 cassettes there seems to be a slight stain/seepage in a corner of the cassette on the decoration panel - its the same corner on each cassette! I can't make my mind up if its water or oil will investigate further.

The system doesn't appear to have a leak as I've leak tested to the correct pressures and over a 48 hour period but seems strange whatever it is! PLEASE SEE PIC 11724

Has anybody else ever come across this problem? maybe an internal solenoid or expansion valve passing oil? Pass.

Cheers

I have seen similar stains to be from condensate a lot. Just make sure your condansate pumps are working properly.
