Damper Vent Position Setting

1.Set fan switch at ON position (continuous fan opera- tion) and close night switch if used.

2.Set system selector switch at OFF position.

3.Turn damper adjustment knob located on control module clockwise slowly until dampers assume desired vent position. Do not manually operate econo- mizer motor, since damage to motor will result.

X.STEP 10 — INSTALL OUTDOOR-AIR HOOD

The outdoor-air hood is common to 25% air ventilation and economizer. If economizer is used, all electrical connections have been made and adjusted at the factory. Assemble and install hood in the field.

NOTE: The hood top panel, upper and lower filter retainers, hood drain pan, baffle (sizes 180 and 240), and filter support bracket are secured opposite the condenser end of the unit. The screens, hood side panels, remaining section of filter support bracket, seal strip, and other hardware are in a package located inside the return-air filter access panel (Fig. 20).

1.Attach seal strip to upper filter retainer. See Fig. 21.

2.Assemble hood top panel, side panels, upper filter retainer, and drain pan (see Fig. 22).
