Acceptance test and acceptance test report
After completion of the installation work (before installation of the thermal insulation) each heating circuit must be accepted, if possible in the
presence of the client.
All further tests must also be documented in an acceptance test report (refer to section Acceptance report / Record of inspection on page 38).
NOTICE
Claims under warranty will not be considered if the acceptance report is not filled in completely.
After completion of work on the thermal insulation final inspection and acceptance of the individual heating circuits is recommended. Usually,
this is the task of the client or the final customer (= final inspection).
Commissioning
Each heat tracing system can only be put into operation if the following conditions are fulfilled:
The acceptance test reports for each heating circuit are complete and the trace heating system has been accepted.
All components of the heating circuit are completely installed and are in working order.
It has been ensured that the heating circuit is operated in conformance with the technical data specified by BARTEC.
It has been ensured that the trace heating system parameters (as indicated in design documenation) will be verified during commissioning.
NOTICE
Upon a cold start. additional heating power is required for heating up tanks and pipes. When starting the system you should allow sufficient time
for heat up. For further information on heat up calculations contact your local BARTEC representative.
Operation
During operation of the electric trace heating system you must ensure that all components of the system are operated within the operating data
specified by BARTEC.
This applies particularly to observation of the maximum temperature. Operation within these operating data is a precondition for possible later
warranty claims.
System documentation
Complete documentation must be carried out for each system, from the project planning stage, through installation and commissioning up to
periodic maintenance of the trace heating system.
This documentation should include the following:
Project planning documents
Results of design calculation e.g. summarized in Print out of Heloc Pro calculation or Manual calculation documented e.g. in BARTEC template
