Ventilation cannot maintain design conditions at ambient extremes
- Design ambient temperatures must be actual site 1% dry-bulb / wet-bulb, not European defaults
- Guaranteed CFM at static pressure specified for each fan model
- Emergency-cooling and alarm redundancy on independent power circuit
"Bidder shall guarantee ventilation performance at the site 1% design ambient conditions listed in Annex C. Failure to achieve guaranteed conditions on Site Acceptance Test shall trigger rectification at Bidder's cost."
