FORM 100.50-EG1 9 YORK INTERNA TIONAL Application Data LOCA TION Of the many factors that can affect the acoustical char- acteristics of a rooftop installation, one of the most im- portant is the unit location.
YORK INTERNA TIONAL 10 For V A V applications, the YORK eco 2 unit uses a VFD to modulate fan speed and maintain a constant duct static pressure. VFDs offer superior control over the operation of the unit at part load, and offer the addi- tional benefits of quieter and more efficient operation when compared to IGV .
FORM 100.50-EG1 11 YORK INTERNA TIONAL The curb should be located according to the location recommendations above, and properly sealed to pre- vent moisture and air leakage into and out of the duct system. Flexible collars should be used when connect- ing the duct work to prevent unit noise transmission and vibration into the building.
