C O N L I N E V E R S I O N Appendix C: Completion checklist and commissioning sheet C1 This installation and commissioning checklist is divided into three parts, as follows. a. Part 1 contains the particulars of the system, installation address and installer’s details. b. Part 2a functions as an installation checklist. c. Part 2b is a visual inspection, or pre-commissioning, checklist. d. Part 3 is for recording air flow measurements from fans. Checking design air flow rates against measured air flow rates C2 Measured air flow rates for all fans should be recorded on Part 3: Commissioning details, as part of the commissioning procedures given in Section 4 of this approved document. The measured values should be compared with their respective design values to determine the following. a. If the measured rate for each fan is equal to or greater than the design value, then the system meets the design standard. b. If any measured value is lower than the design value, an adjustment should be made to correct the system. All air flows should then be remeasured. If necessary, further adjustments should be made until all air flows match their design values. Demonstrating compliance C3 All three parts of the installation and commissioning checklist should be completed. The relevant sections of Parts 2 and 3 should be signed by a person who is both competent to install the system and responsible for installing and commissioning the system. C4 The three-part form should be completed for each installation address. A copy should be submitted to the building control body as evidence that the system has been correctly installed, inspected and commissioned. 42 Approved Document F Volume 1, 2021 edition Building Regulations 2010 O N L I N E V E R S I O N
