In 2014 the fully installed ASHIPH (Aerogel, SHifter, PHotomultiplier) system began its operation in the KEDR experiment at the VEPP-4M e+e- collider. The system contains 1000 liters of aerogel with refractive index 1.05 in160 counters that are arranged in two layers. Light collection is preformed by means of wavelength shifters. 160 Micro-Channel Plate PMTs with multialkali photocathode are used as photodetectors. Detection efficiency for relativistic particles was measured with е+е- -> e+e- events and cosmic muons. Detection efficiency for under-threshold particles was measured with cosmic muons. From these data pi/K-separation of 4 sigma at the momentum 1.2 GeV/c was obtained.
