Assembly

1.Determine if ventilation air is required in building. If so, determine the minimum amount to be supplied by each unit and record quantity of ventilation air needed for use in Step 5.

2.Remove ®lter access panel by raising panel and swing- ing panel outward. Panel is now disengaged from track and can be removed. No tools are required to remove ®lter access panel. Remove outdoor-air opening panel. Save panels and screws. See Fig. 19.

3.Assemble outdoor-air hood top and side plates as shown in Fig. 20. Install seal strips on hoop top and sides. Put aside screen retainer and retainer screw for later assembly. Do not attach hood to unit at this time.

4.Insert economizer plug into economizer harness. Re- move tape from barometric relief damper. See Fig. 28.

5.If ventilation is not required, proceed to Step 6. If ven- tilation air is required, perform the following:

a.Make sure the factory-installed jumper is in place across terminals P and P1 on the economizer logic module. T and T1 should be disconnected during adjustment.

b.The 2 potentiometers with slots for adjustment are located on the face of the economizer logic module. Turn the lower potentiometer fully clockwise. The dampers should be fully closed. Turn the potenti- ometer gradually counterclockwise until the de- sired position is reached.

c.Connect T and T1 to the 24V power supply.
