ECONOMISERS

Note : Gravity exhaust dampers are required with
economisers.

The economiser is used with LINEA units in downflow and
horizontal air discharge applications. The econmiser uses
outdoor air for free cooling when temperature and/or humidity
is suitable.

INSTALL ECONOMISER

1. Disconnect all power to unit.

2. Release latches and open filter access panel.

3. Align bottom of economiser with economiser support

bracket and slide economiser into unit. See figure 51.

4. Fit economiser end plate over end of economiser and

secure end plate with sheet metal screws.

5. For wiring detail, refer to unit wiring diagram and infor-

mation supplied with economiser.
