Never use air or a gas containing oxygen during leak tests to purge lines or to pressurise a machine. Pressurised air Consult Carrier Service for this type of test. Carrier mentions here only the principle of a test without removing the pressure switch: mixtures or gases containing oxygen can be the cause of an explosion. - Page 8 1 - INTRODUCTION During refrigerant removal and storage operations follow ATTENTION: No part of the unit must be used as a walk-way, applicable regulations.

9 - MAJOR SYSTEM COMPONENTS AND OPERATION DATA 9.2.2 - Oil separator In these units, the oil separator is a pressure vessel that is mounted under the outside vertical condenser coils. Dis-charge gas at the compressor outlet is directed towards the bottom of the oil separator ring and most of the oil separates from the gas by strong deceleration and by gravity. The gas then flows through a wire mesh screen where the remaining oil is separated by coalescence and flows to the bottom of the ring. The gas is now free from oil and leaves the ring at the top towards the condenser. 9.2.3 - Economiser function The economiser function includes a liquid line valve, a filter drier, two EXVs, a plate heat exchanger as well as protection devices (fuse ... -
