CONVENIENCE OUTLET — An optional convenience out- let provides power for rooftop use. For maintenance personnel safety, the convenience outlet power is off when the unit dis- connect is off. Adjacent unit outlets may be used for service tools. An optional “Hot Outlet” is available from the factory as a special order item.

NOVAR CONTROLS — Optional Novar controls (ETM 3051) are available for replacement or new construction jobs.

MANUAL OUTDOOR-AIR DAMPER — The outdoor-air hood and screen are attached to the basepan at the bottom of the unit (for shipping).

Assembly:

1.Determine the amount of ventilation required for build- ing. Record the amount for use in Step 8.

2.Remove the filter access panel by raising the panel and swinging it outward. The panel is now disengaged from the track and can be removed. No tools are required to re- move the filter access panel. Remove the outdoor-air opening panel. Save the panels and screws. See Fig. 11.

3.Separate the hood and screen from the basepan by remov- ing the screws and brackets securing them. Save all screws and discard the brackets.

4.Replace the outdoor air opening panel.

5.Place the hood on the front of the outdoor air opening panel. See Fig. 12 for hood details. Secure the top of the hood with the 6 screws removed in Step 3. See Fig. 13.

6.Remove and save the 8 screws (4 on each side) from the sides of the manual outdoor-air damper.

7.Align the screw holes on the hood with the screw holes on the side of the manual outdoor-air damper. See Fig. 12 and 13. Secure the hood with the 8 screws from Step 6.

8.Adjust the minimum position setting of the damper blade by adjusting the manual outdoor-air adjustment screws on the front of the damper blade. See Fig. 11. Slide the blade vertically until it is in the appropriate position determined by Fig. 14. Tighten the screws.

9.Remove and save the screws currently on the sides of hood. Insert the screen. Secure the screen to the hood using the screws. See Fig. 13.

10.Replace the filter access panel. Ensure that the filter access panel slides along the tracks and is securely engaged.
