PERFORMING ROUTINE MAINTENANCE
1.The motors are factory lubricated. Lubricating the bearings is not recommended.
2.The heat recovery coremust be handled with care. To ensure maximum efficiency of the plastic partitions wash core once a year following the season of most intense use.
Allowthe heat recovery core to soak for 3 hours in a solution ofwarmwater and mild soap. Rinse under a stream ofwarm water. Hot water and strong detergent should NOT be used,as it will damage the heat recovery core.
3.A dirty air filter will cause excessive strain on the blower motor. The filters in your HRV are washable and should be cleaned every 3months.Use a vacuumcleaner to remove the heaviest portion of accumulated dust, then wash in warm water.
The Air Exchange Indicator light on the auto control will indicate when filters should be cleaned. The light will flash on and off until the door is opened to service the unit.
4.Regularly check the screen on the exterior intake hood and clean as necessary.
