Step 7:

Slide the return air damper into the unit as shown using some ofthe screws removed in Step 5.

Step 8:

Secure the return air damper to the unit with the screws removed in Step 6 through the slotted holes in the damper section.

Do Not tighten screws at this time.

Step 9:

Connect the linkage from the return air damper to the fresh airdamper. The linkage rod is shipped connected to the return air damper. To connect the linkage to the fresh air damper, openthe fresh air damper and insert the rod through the opening inthe damper bracket. With the rod through the fresh air damperbracket, close the fresh air damper tightly, and tighten the setscrew on the fresh air damper bracket as shown.

Note: A. Damper bracket is shipped in lower position. If

installing in small cabinet reposition bracket toholes 8" above current location

B. Linkage rod should be flush with the back of thefresh air damper bracket.

Step 10:

Route the blue and violet wire from the Logic Module “+” and“S” terminals through the lower bushing provided in the freshair damper as shown. These wires will be connected to theEnthalpy Control mounted on the fresh air hood as shown inStep 13.

Step 12:

Install the assembled Barometric Relief Hood as shown.Using the “keyhole” slots on the barometric relief hood, placethe barometric relief hood over the screws and slide down intothe slots and tighten screws in place. Attach (4) tinnermanclips to the top flange of Barometric Relief Hood as shown infigure.

This is the time to tighten all screws that were previouslynot tightened.

Step 13:

Install the assembled Fresh Air Hood as shown using #10 - 16x ½ self tapping screws. Place fresh air hood approximately 3” down from top of the unit and flush with flange on hood side.Route wire to Enthalpy Control in the lower right hand cornerof the Fresh Air Hood as shown. Connect the violet wire to the“+” terminal and the blue wire to the “S” terminal.

Step 11:

Plug the economizer cable into the unit as shown. The“jumper” plug that ships with the unit should be removed andsaved in the control compartment for future needs.
