Monitoring of operation
To ensure satisfactory operation, it is required that you enter certain routines in a logbook on a
regular basis. You can use the items listed in the
Start-up log
, which is page 2 of the
Checklist
il-
lustrated in Fig. 24. The service engineer will need this information in connection with, for exam-
ple, error reports.
In addition to the items listed in the start-up log, all other activities of service, maintenance or re-
pair work must be entered into your logbook as required by EN 378 and national laws.
Checklist
Along with this Operating manual we have provided a
Checklist
, as shown in Fig. 24, which will
serve as a help to the service engineer and
must be filled in during commissioning and
start-up
.
Keep the filled-in checklist, and send a copy to SABROE Factory as documentation that the unit
has been installed and commissioned correctly. The checklist will be required in case of a warranty
issue.
