and in thousand hours from 1.0 hours onwards (example: when the display shows 35, this means 35 hours
and when the display shows 3.5, this means 3,500 hours).
11.17.4 Indication of a service warning/service alarm
A service warning/alarm is an exceptional event and requires the attention of the operator/service technician. The
chiller will not be stopped.
When a service warning/alarm is active, the

button and keep it pressed for at
least 20 seconds).
NOTE: the operator/service technician must check the chiller and eliminate the problem that led to the
activation of the service warning.
