11.7 and 11.8 for more detailed adjustment information. 10.0 MAINTENANCE RenewAire ERVs are built to operate with minimal maintenance. After unit commissioning, the prima- ry areas of attention are the air filters and periodic lubrication of the fan motors and fan bearings.
Each motor manufacturer specifies the frequency of maintenance and the amount and type of grease to use on the bearings. Do not mix different types of grease. Check the manufacturer’s web site for each specific motor. RENEWAIRE.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.627.4499...

This will allow for thermal expansion of the grease. • After greasing, run the motor for a while (at least five minutes) to allow the motor to discharge any excess grease. RENEWAIRE.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.627.4499...
Leave a small amount of grease on the zerk as a protective coating. • In all cases, Industry Best Practices should be observed. Maintain a record of every lubrication and the type of lubricant used. 1.800.627.4499 INSTALLATION, OPERATION AND MAINTENANCE MANUAL RENEWAIRE.COM...

11.5 FILTER REPLACEMENT PRACTICES RenewAire has provided a filter replacement tool called a filter extractor hook. See picture below. In ad- dition, the filter spacers have a tab on the ends where a pull cord can be inserted. With a cord installed in the tab holes, it is possible to simply pull the cords and withdraw six filters at once.
Be sure to reinsert the test port cap when air flow measuring is finished. Motors that are controlled by factory-installed VFDs are equipped with fixed sheaves. The entire speed range that can be obtained with variable sheaves can be obtained by adjusting the VFD. RENEWAIRE.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL 1.800.627.4499...
