1.1Completion of pre-commissioning tests and compliance with procedures laid down in system documents are ascertained.
1.2System documentation is analysed to extract objective flow rates and other relevant information for preparing of recording sheets in accordance with company procedures.
1.3Commissioning instruments are procured and calibrated in accordance with system documents.
Outcome 2
Commission the HVAC systems.
Evidence requirements
2.1The system is test-run in accordance with system documents and commissioning method and programme.
2.2Readings are taken and recorded from the system test-run.
2.3System is adjusted and readings are re-checked for conformity to performance levels and ranges specified in system documents.
Outcome 3
Complete HVAC system commissioning documentation.
Evidence requirements
