ZONEFIRST Warranty Policy

When Installing Any ZoneFirst Product ...

Read instructions carefully. Failure to follow the instructions could damage the product or cause a hazardous condition. Ensure that the installer is a trained, experienced service technician. After completing installation, use these instructions to check product operation.

 

Location

The Zone Dampers are installed typically near the furnace/air handler plenum and in the air duct takeoff to the zone. Always make sure the dampers are accessible for wiring, checkout, duct cleaning and replacement of damper or motor is ever needed.

 

Humidification

Do not install dampers in heating systems where spray or atomizing type humidifiers are installed in the furnace plenum or air supply duct. Excessive lime or mineral deposits accumulate on damper blades and cause improper operation. For humidification, use evaporation type humidifiers or return air type humidifiers.

 

Installation Considerations

Install Zone Dampers (ZDS) or (ZDB) into a squared air duct. Frame misalignment may jam the damper blades. Do not weld dampers to air ducts.
