Why does oil spurt out when ZR3 is compressing
(San Juan Puerto Rico)
Oil spurts out oil filler pipe when ZR3 unit is compressing .
Unit was in service, it shut down, noticed oil all over the compressor side of the unit, refilled.
Started unit and noticed oil spurted out of the oil filler pipe, removed lp and hp piston diaphragms, they wee not cracked.
Replaced them anyway, still have the same problem.
