STEPS FOR STARTING HVAC SYSTEM IN CITY OWNED BUILDINGS IN LOWER MANHATTAN:
Central Air Conditioning Systems
1) Clean thoroughly air intake louvers and MER. 2) Remove existing air filters on the return air/mixed air systems and outside air systems, if applicable 3) Clean out side air intake system using I-IEPA filtered vacuums capable of trapping and retaining 99.7% of all particles larger than 0.3 microns to insure capture of solid particles formed by condensation of vapors of molten metal (fumes) and majority of solid particles formed by incomplete combustion of oil (smokes). 4) Install new filters. 5) Run supply fans only for a short period of time to create positive pressure to purge out contamination through available cracks etc. 6) Run supply and return fans to trap solid particles in the recirculation air. 7) Replace filters. 8) Operate air-conditioned space initially above 45% RH (not to exceed 60% RH) in order to keep odor perception and irritation at a minimum. The irritation is greatest at low relative humidity.
