Page 17: Radiated Noise
INSTALLATION HE-Series Indoor 4.3.3 Radiated Noise The HE2XIN is insulated with high-density fiberglass. This provides significant attenuation of radiated sound. The outlet ducts can be significant sources of radiated sound as well. The FA and EA ducts (outlet ducts) should be insulated for sound control. This insulation should start at the unit. At a minimum the first ten feet of duct should be insulated. -

Page 25: Unit Startup
OPERATION HE-Series Indoor 6.3 UNIT STARTUP 6.3.1 Fixed-Speed Units Most fixed-speed units do not have any external controlling signals and only require turning on the disconnect switch, located on the E-Box. When the disconnect switch is turned ON, any dampers will first move into their correct operating positions and then power is suppled to the motor contactors, causing the fans to run. -

Page 28: Sheave Adjustment
OPERATION HE-Series Indoor 6.4.3 Sheave Adjustment All fan motors that are not controlled by a VFD are equipped with an adjustable sheave. These adjustable sheaves must be re-set in the field to attain optimum performance of the ERV. This adjustment is to be done after all ductwork is connected. Adjustable sheaves are held in position on the drive motor shaft by a set screw that is normally hidden until the belt(s) is removed. -
