Page 15: Radiated Noise
INSTALLATION HE-Series Indoor 4.3.3 Radiated Noise The HE4XINV 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. -

INSTALLATION HE-Series Indoor 5.6 QUICK-START FOR TESTING CORRECT 3PH WIRING All units that run on 3 phase power should be test-run immediately after high voltage wiring connections are made. This will verify that the three phases are properly connected, that the dampers will open and close properly and the fans are working properly. -
Page 23: 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 26: 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. -

Page 29: Enthalpic Core Removal
MAINTENANCE HE-Series Indoor To access enthalpic cores for cleaning, remove the air filters. To clean enthalpic cores, all exposed surfaces must be vacuumed with an attachment having long, soft bristles. The greatest buildup of dirt and dust will normally be on the leading 1–2 inches of the inlet side (closest to the air filters). -
