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

Fig. 24. The service engineer will need this information in connection with, for example, error reports.
In addition to the items listed in the start-up log, all other activities of service, maintenance or repair 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.
