4.4 Maximum compressor cycle
Maximum permitted starts per hour: 10.
The factory setting of the XCM25D system controller already
takes into account the maximum permitted starts and stops of the compressor and also controls
running time and minimal downtime. It is recommended to change these settings only in exceptional
cases.
4.5 Checks before starting & during operation
IMPORTANT
Liquid valves not fully opened! Liquid trap!
Both valves should be fully
opened on the liquid line, in order to prevent liquid trapping.
▪
Check that all valves are fully opened.
▪
Set the essential parameters of the electronic controller in the programing level 1 (refrigerant
type, compressor cut-out/in settings (ZXDE only), fan setpoint
….) according to the required
application.
▪
We recommend to check the oil level in compressor after starting and operation conditions have
stabilised, and to add oil if needed to ensure a sufficient oil level (halfway up the sight glass).
