Danger of Electrical Shock when installing dampers on an installed unit. LWYS DISONNET POWER SOURE EFORE INSTLLING! More than one disconnect switch may be required. Installation Dampers are not factory installed but are factory wired. Dampers for this model are designed for installation indoors. Dampers for this model are designed to be installed at the Exhaust ir and Fresh ir locations (See air stream location stickers on side of unit). Remove damper assembly from carton. The motorized actuator is pre-installed and needs no adjusting. Slide damper assembly onto the factory installed round duct collars on the unit at the location(s) described above. NOTE: Position actuator for easy access. Secure damper assembly in appropriate manner. ontinue ducting the unit as described in the Installation and Operation Manual that came with the unit. NOTE: When insulating the duct around damper provide access to the damper actuators, which are located on the outside of the duct, so they can be serviced or inspected in the future. The damper actuators come wired with the appropriate low voltage wire plug. Remove black plastic plug from the side of the unit and the mating low voltage wire plug is located behind this plug. Simply plug the wire connector from the end of the actuator into the wire plug in the unit. NOTE: There is a proper orientation of these plugs in order for them to be correctly mated. lose inspection of the wiring connectors will reveal a notch in the actuator plug and a tab in the unit plug that need to line up for proper connection. Use conduit, strain relief etc. as required by code to secure damper wiring. Sequence of Operation t start-up: Once plugged in, when the ERV unit receives an external call for ventilation, the blowers should not turn on immediately. The isolation dampers are opening inside the duct. It will take less then 0 second for the dampers to open, at which point a low-voltage end switch in the actuator closes. The end switch calls on motor starter to turn on the blower motor. t shut-down: When the ERV no longer calls for ventilation, the isolation dampers will begin closing. Once the dampers are approx. % from closure (-0seconds), the end switches open, and the motors will stop. UTION: lowers may still be spinning. NOTE: Isolation dampers are shut down and in the closed position when the unit is not operating. NOTE: Isolation dampers return to the closed position if power to the unit is interrupted. ommissioning heck all dampers and insure they open and close properly and without binding. pply power to motorized dampers to ensure the actuator opens and closes the damper as designed. NOTE: heck for unobstructed operation. NOTE: For indoor units, the dampers are located inside the ductwork attached to the unit. Therefore, check damper operation after installing the first lengths of ductwork that cover the damper, but before completing the ductwork and making it inaccessible. Testing and replacement of dampers and actuators If dampers fail to open at the signal for ventilation, disconnect power to the unit. To determine if the actuator is defective, disconnect the v power source. onnect the actuator directly to a known v power source with an appropriate cable. If the damper operates correctly, the problem is in the internal wiring connections. Model HEX: if only one motor starter is provided, the damper end switches are connected in series and both actuators need to be checked. Troubleshooting ctuator: Refer to supplied Installation Instructions from manufacturer. Damper: Low air flow: Unit damper(s) not fully open, check for unobstructed operation. lear any obstruction; re-tighten the actuator U-clamp; or replace damper actuator. Dampers open, but blowers don t run: check end switch closure. Maintenance Damper bearing are a nylon material and do not need lubrication.
