Lid Assembly, Opening/Closing the Lid | Honeywell F111 Series 1

F111 (SERIES 1,2) IN CEILING MEDIA AIR CLEANER

•Never rest the air cleaner on the T-bar.

5.Level the air cleaner.

6.Turn the air cleaner power on and check for proper operation for 2 to 3 minutes. There should be a smooth, powerful blower sound and air discharging from both ends of the air cleaner.

7.Turn off the power.

8.Install the particle filter. Note airflow direction arrows if present. If arrows are not present, install the filter with the fasteners facing downward.

11.For Series 1 only. Be sure the fastener tabs are facing downward and fasten them.

12.For Series 2 only. Be sure both catches are turned down and filter rests firmly on catches.

13.Install the prefilter in the air cleaner lid. Position the metal screen mesh so it is facing upward when the lid is closed.

Lid Assembly

The F111 lid is held in place by two separable hinges and two spring loaded plungers. To install the spring loaded plungers on the lid follow these steps:

1.Pull the plunger back and twist a quarter turn to reveal the wrench flat on the body of the spring loaded plunger (see Fig 6.)

2.Turn the threaded barrel out of the spring plunger.

3.Insert the threaded barrel through the hole in the lid and turn the spring loaded plunger onto it.

4.Tighten the assembly with wrenches.

5.Repeat steps 1 through 4 for the second plunger.

9.Fasten the filter tabs. Be sure there is a snapping sound when fastened. The tabs are commercial Velcro and require more force than lightly pushing them together.

IMPORTANT

Do not touch the pleated filter media. Handle only the filter frame to prevent damage to the filter media.

10.Remove CPZ™ sorbent modules (select models) from their packaging and install one module into each cavity. Be sure the fastener tabs are facing downward and fas- ten them.

Opening/Closing the Lid

To open the lid, pull the spring loaded plungers back to disengage the plunger. Carefully swing the lid open on the hinges while supporting the filter and/or adsorbent modules as required. To close, swing the lid into the closed position and engage the plungers.

Removing /Replacing the Lid

IMPORTANT

The lid is heavy. Make sure that it is supported before removing.
