This will verify that the three phases are properly connected, that the age wiring should dampers will open and close properly and the fans are working properly.
- Page 25 OPERATION HE-Series Outdoor 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 OPERATION HE-Series Outdoor 6.4.1 All Fixed-Speed Units For all fixed-speed units, manometer readings are taken and then the adjustable sheaves on the motors are adjusted to reset fan speeds. Equipment Required A magnehelic gauge or other device capable of measuring 0–1.0 in. water of differential pressure.

- Page 28 OPERATION HE-Series Outdoor 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 MAINTENANCE HE-Series Outdoor 7.0 UNIT MAINTENANCE WARNING RenewAire ERVs are built to operate with minimal maintenance. After unit commissioning, the Danger of injury if unit primary areas of attention are the air filters, periodic lubrication of the fan motors and annual starts unexpectedly.
- Page 30 MAINTENANCE HE-Series Outdoor 7.5.1 Belt Tension Premature or frequent belt failures can be caused by improper belt tension (either too loose or too tight) or misaligned sheaves. Abnormally high belt tension or drive misalignment will cause excessive bearing loads and may result in failure of the fan and/or motor bearings. Conversely, loose belts will cause squealing on start-up, excessive belt flutter, slippage and overheated sheaves.
