Is the installation complete, with no obvious defects?	YesNo
Do all internal doors have enough undercut to allow air transfer between rooms as detailed in paragraph 1.25 (i.e. 10mm above the floor finish or 20mm above the floor surface)?	YesNo
Has all protection/packaging been removed (including from background ventilators), so that the system is fully functional?	YesNo
Are systems clean internally and externally?	YesNo
Has the entire system been installed to allow access for routine maintenance and to repair/replace components?	YesNo
2b.2 Visual inspections – general (continuous mechanical extract ventilation and mechanical ventilation with heat recovery systems only)
Have appropriate air terminal devices been installed to allow system balance?	YesNo
Have the heat recovery unit and all ductwork been effectively insulated and sealed for all heated and unheated spaces?	YesNo
Is the condensate connection complete and does the condensate drain to an appropriate location (mechanical ventilation with heat recovery only)?	YesNo
Are filters installed?	YesNo
For ducted systems, has the ductwork been installed so that air resistance and leakage is kept to a minimum?	YesNo
2b.3 Other inspections – general (all systems)
At initial start-up, was there any abnormal sound or vibration, or unusual smell?	YesNo
During continuous operation, was there any excessive noise?	YesNo

NOTE: 1. All references to tables and paragraphs are to Approved Document F, Volume 1: Dwellings.
