hi we have a rthb380 unit that works well ,but under extreme conditions ,condesning water supply is 34 deg c ,pressure drop on both evap and condenser are as desigend, unit operates all summer at 100% capacity ,their is no odd noise from compressor ,the unit is charged with r-22 ,
recently oil chekup came back with 95 ppm of copper, all other parameters are ok, no metal or oxidation ,
the unit uses oil025e, we suspect the bearings in the comp or errosion in pipes.
anybody encounter this problem ???
we are going to change all the oil and filter,
any ideas???:)
