Make air quantity medsurements in ducts by pitot tube traverse of ~ntire cross sectional area of <br />du~t. <br />C. Measure air quantities at air i~ilets and outlets. Log shall show each successive test. <br />U- Adjust distribution system to obtain uniforrn space temperatures free from objectionable drafts <br />,3nd noisc, <br />E. Use volume control devic,es to ~gulate air quantities only to the extent that adjustments do <br />nat cr~eate objectionable air motion or sound levels. Effect volum~ co~trol by duct inbemal <br />devices such as dampers and splitters. <br />F. Vary total system air quantifies by adjustment of fan speeds. Provide drive chariges as required <br />a# no additional cost te Owner. Vary branch air quantities by damper regulation. <br />G. /~djust f,~ns to deliver within S perce~t of specified flow. Adjust air outlets and inlets to within <br />I 0 perccnt of spec~ed flow. ' <br />H. Adjust fan and ir~let vanes for variable air volume systems with sufficient number of teRni~al <br />units at fiall cooling to achieve fan flow specified. Close other units. <br />/Ldjust outside air to alf Fans as scheduled. Measure at outside air for variable air v~ume fans at <br />ful) flow and with all t,erminal u~its at minimum position.
