5. Charging Procedure Refrigerant charging procedure The scroll compressor design requires system charging as quickly as possible with liquid refrigerant into the liquid line This will avoid running the compressor under conditions where there is insufficient suction gas Sufficient suction gas is available to cool not only the motor but also the scrolls Temperature builds up very quickly in the scrolls if this is not done Do not charge vapor gas refrigerant into the ZX Scroll unit The suction service valve must not be fully closed at any time while the compressor is running To do so would cause damage to the compressor in the same manner as explained above This valve is provided for ease of connection and for the fitting of service gauges without removing the unit panel It is recommended to charge the ZX unit with refrigerant via its service valves It is recommended to break the vacuum in the system with a partial charge of the refrigerant before starting the system For charge adjustment it is recommended to check the liquid sight glass just before the expansion valve Oil charging procedure Emerson ZX condensing units are supplied only with a compressor oil charge After commissioning the oillevel should be checked and topped up if necessary The oil level should be approximately halfway up the sight glass ZXL ZXD units Oil can be charged through the Schraeder valve on suction valve Scroll compressor rotation direction Scroll compress
