ACG Commissioning Guideline
Appendix C
Sample Format for System Verification andStart-Up Checklists
NOTES TO APPENDIX C
This appendix contains sample systems verification and start-up checklists for a selection of equipment used frequently in typical HVAC systems.
There is no intention in the appendix to provide sample checklists for all possible equipment included in any design. These checklists are intended to illustrate a level of detail that is appropriate in good commissioning practice, and to suggest a practical format. As such, they contain typical items that are often required to be included in the inspections and checks carried out, and documented, prior to and during equipment start-up.
The sample checklists are generic; thus they do not apply to any specific project, and so the list of check items is generic, not specific. Commissioning authorities must develop systems verification and start-up checklists for every piece of equipment within the scope of any commissioning project, and those checklists must include all items included in the specific design that require checking.
There is a Table of Contents on the next page listing the sample checklists included in this appendix.
ACG assumes no responsibility for how the material in this Appendix may be utilized by users of the Guideline; the users assume full responsibility for any and all liability that may arise from any reference to, or use of, this material.
