Step 2:

Remove the control access panel. Remove the bloweraccess panel. Keep all screws for later use. See Figure 2.

Step 5:

Position the power exhaust assembies close to theopening cut in the return duct. Locate the harness markedwith the S2 connector on the power exhaust assembly withthe control box. Locate the harness marked with the P2connector on the power exhaust assembly without thecontrol box. Connect the S2 harness with the P2 harnesswithin the return duct. Secure the harness. Route thepower and control harnesses marked S1 and S11 thru thehole cut in the return duct to the return area of theeconomizer. See Figure 4.

Step 6:

Use self-tapping screws provided to mount the powerexhaust assembly over the hole cut into the return ductopening. After the power exhaust assembly is mounted tothe return duct, pull any remaining slack in the powerexhaust power and control harnesses thru the return ductinto the return area of the economizer.

WARNINGElectric shock hazard. Can cause injuryor death. Before attempting to performany service or maintenance, turn theelectrical power to unit OFF atdisconnect switch(es).

Step 4:

Cut hole in return duct 19 38" wide x 18" tall where power

exhaust is to installed. See Figure 3.

Locate the power exhaust control harness with wirenumbers 843 (grey) and 844 (brown). Connect thisharness to the location marked EX-FAN / COM on theeconomizer controller. Secure this harness to avoiddamage during normal damper operation. See wiringdiagram for details.

Step 7:

Locate high voltage harness with black, blue and yellowwires (NOTE - yellow wire is not included with single phasepower exhaust assemblies). Route the power harnessthru the unit and along the existing harnesses in the unitback to the unit control panel as illustrated in Figure 5.Secure the power exhaust power harness to the existingharnesses throughout the unit with (field supplied) wireties.

WIRING ROUTING

Figure 5

Step 8:

Connect the power harness to the line side of contactor M1(see unit control panel component map for location ofcontactor M1). Remove and reconnect existing wires asnecessary using the pigtails provided with the powerexhaust power wires. Connect the black wire to terminal 1on contactor M1, the blue wire to terminal 2 on contactorM1 and the yellow wire to terminal 3 on contactor M1(Yellow wire only on 3 phase units). See wiring diagram.

Step 9:

Install control access panel and blower access panel using screws originally used to hold the panels in place. SeeFigure 6.

Step 11:

Reconnect power to the unit - follow all safety instructions,rules and codes.

See unit Installation, Operation and Maintenance manualfor instructions to verify the unit controller recognizes theinstallation of the power exhaust.

Note: Once the unit is operating properly, seal anyopen joints, holes or seams with silicone caulking(field supplied), to make the power exhaustcompletely air and water tight.
