Installation and Wiring
The mounting position on the ver- tical classroom unit ventilator configuration allows complete ac- cess to the Tracer ZN.520 by re-
moving the front panel. (See Figure 9: “Vertical classroom unit ventilator end pocket”) The
mounting plate swings out of the way with the removal of a single screw to allow access to the com- ponents behind the control board.
The mounting plate on the hori- zontal classroom unit ventila- tor configuration is designed to slide out with the removal of a sin- gle screw for complete access to the Tracer ZN.520. (See Figure 10: “Horizontal classroom unit venti- lator end pocket”) The location of the control board on this unit con- figuration allows complete access to the other components in the end pocket when the front panel is removed.
For additional convenience, quick connects and modular wire har- nesses are used on the control board and mounting plate. (See
Figure 11: “Quick connects to con- trol board in the classroom unit ventilator”) These quick connects
help facilitate ease of wiring devic- es (e.g., zone sensor) to the control board, and helps add accessibility to major components.
