skilled refrigerator technicians.
The refrigerating fluid and the lubricating oil, con-
tained in the circuit, must be collected according to the
laws of your Country.
The Maintenance Programme described below should
be carried out by a skilled technician, preferably work-
ing under a maintenance contract.

sure that the bearings are not running hot.
