Ventilation System
The rear, front, and side panels of the terminal have ventilation grids for heat removal. The rear panel
has four ventilation units installed (Fig. 6.2 and 6.3).
Air flows in through the perforated front and side panels, circulates through all internal components,
cools them down, and then is removed with the help of ventilators located on the perforated rear panel.
The device incorporates 2 ventilators. The ventilation units are detachable. Procedure for
dismantlement and installation is described in Chapter 33.
