Start-up Procedures

Installation of New Units

1.Follow all instruction for installation of classroom unit ventilators as detailed in UV- IOM-1 (Installation Operation Maintenance manual).

2.Disconnect power or disable the circuit breaker to unit.

3.Run communication link wire when required. (See wiring diagram in the unit).

4.Install zone sensor when required. (See wiring diagram in the unit and zone sensor submittals).

5.Reapply power.

6.Check for GREEN Status LED operation to ensure power has been made to the TracerTM ZN.520 unit controller.

7.Check for YELLOW Comm LED operation to help ensure com- munication has been made to the Tracer ZN.520 unit control- ler when required.

Peel IDENTIFICATION TAG from unit and place in the Appendix of this document, or on building plans for future location use. The actual room location on the tag may be hand written.
