Hey Guys,

Wondering whether anyone can help at all, one of our engineers called today with a fault on a mitsubishi heavy industries vrf saying the unit keeps going out on lp. After asking the engineer the usual questions he cant seem to find a leak although he says there are traces of oil around the suc/dis pipes on the condenser. I'm wondering whether anybody has any technical details on the above unit at all as the commissioning data is not present with the unit and i'm unsure of additional charge weights. Unit has a standard charge weight of 17kg R410A.
I've already done a search on here and couldnt find anything and have also tried 3dair's site and heronridge and mhi's site, does anyone have any other suggestions.

Many thanks in advance.

Lee
