4.Remove screws along bottom of damper assembly. Lo- cate and mount blockoff baffle using these screws.

5.Assemble 2 ®lter tracks side-by-side with the as- sembled ends together.

6.a. Attach mounting angle (without tabs) to the as- sembled end of the ®lter track. See Fig. 23.

b.Attach 6 green clips (provided) to mounting angles. Engagement section of clip faces inside of rack.

c.Attach remaining mounting angle (with tabs) to other end of the ®lter track with no. 10 screws provided. See Fig. 24.

7.a. Place ®lter track assembly in bottom of hood by plac- ing tabbed end into slotted side (with tab on bottom) and attaching opposite end to hood with speed clips and gasketed screws provided. Tabs can be hand bent after inserted into the side.

NOTE: The ®lter track assembly end with screws should face away from the other hood when mounted on the unit.

NOTE: Tabs from both ®lter tracks will be in the same space. After one ®lter track has been inserted into board, bend the tabs so they will not interfere with installation of the second hood.

b.Attach black seal strip to ®lter cover. Seal strip should be applied to ¯ange (covering holes) and center of large ¯ange. See Fig. 25.

8.Slide two 20 x 25-in. ®lters into cross members of hood assembly. Attach ®lter cover over ®lters with screws and speed clips provided.

Minimum Damper Position Setting

Setting of the outdoor air damper position is performed in conjunction with a shortened version of the ®eld run test. This is performed by ®rst opening DIP switch no. 4 then no. 6.

The outdoor-air damper closes. The control allows 90 seconds for the damper to close in case it is in the full open position. Next, the indoor-fan contactor will energize. The outdoor air damper will remain at 0% for 30 seconds. It will then move to the 10% position for another 30 seconds. This will be repeated at every 10% increment for 30 seconds until the damper reaches 100% open. Close DIP switch no. 4 during the 30 seconds immediately after the desired outdoor air mini- mum damper position. The 30-second time period is to allow time where DIP switch no. 4 can be closed. The default value of the minimum outdoor air damper position is 20%. If the desired minimum position is 30%, allow the damper posi- tion to go to 10% for 30 seconds, then 20% for 30 seconds, and when it reaches 30% close DIP switch no. 4 during the 30-second period following the 30% position.

The minimum outdoor air damper position is now set. Close DIP switch no. 6.

B. Economizer Settings

Accessory Enthalpy Control (Fig. 26)

The control (HH57AC077) is mounted in the economizer hood. See Fig. 17. The enthalpy setting adjustment is on the en- thalpy control. For maximum bene®t of outdoor air, set en- thalpy sensor control to A. See Fig. 27 and 28.

Enthalpy Control Installation

The outdoor air enthalpy control is installed on the inside panel of the outdoor air hood. The enthalpy control should be mounted when the outdoor air hoods are assembled. To install the con- trol, perform the following procedure:

1.Turn off all power. Ensure disconnect is locked out.

2.Remove the economizer inlet ®lters from the bottom of the right hand economizer hood. See Fig. 29.
