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

Approvals:

Underwriters Laboratories Inc.: Listed.

Canadian Standards Association: Listed.

Accessory: 32000234 Variable Speed Switch.

Replacement Parts See Parts List, Table 4.

The number of F111 (series 1,2) air cleaners that are needed is determined by taking into account the number of occupants and the volume of the space. Type of contamination, outdoor air quality and use of the area are also factors. Refer to Table 3 for general guidelines when determining how many air cleaners are needed.

EXAMPLE: One air cleaner can provide 2.5 air changes per hour in a 24,000 cubic feet (720 cubic meters) no smoking area. Table 3 suggests two air cleaners for a 24,000 cubic feet area because most areas have contaminants that require more units to provide quality air.

If any questions should arise concerning determining the number of air cleaners needed for an area, consult your distributor or local Honeywell Commercial Air Cleaner Distributor.

WARNING

TO REDUCE THE RISK OF FIRE,ELECTRICAL SHOCK, OR INJURY TO PERSONS,OBSERVE THE FOLLOWING:

1.Installation Work And Electrical Wiring Must Be Done By Qualified Person(s) In Accordance With All Applica- ble Codes And Standard, Including Fire Rated Con- structions.

2.When Cutting Or Drilling Into The Wall Or Ceiling, Do Not Damage Electrical Wiring And Other Hidden Utili- ties.

3.Never Place A Switch Where It Can Be Reached From A Tub Or Shower.

4.Use This Unit Only In The Manner Intended By The Manufacturer. If You have Questions, Contact The Man- ufacturer.

5.Before Servicing Or Cleaning Unit, Switch Power Off At Service Panel And Lock Service Panel To Prevent Power From Being Switched on Accidentally.

6.If This Unit Is To Be Installed Over A Tub Or Shower, It Must Be Marked As appropriate For The Application.

Choose Location

Choosing the correct location for the air cleaner affects the overall performance of the unit. The bidirectional airflow pattern must flow into the longest reaches of the zone being cleaned. See Fig. 2.

Construction.

The air cleaner is designed to be suspended centrally in a space and mounted into or on a ceiling. The cleaning footprint of the air cleaner is rectangular with air patterns that move clean air to the corners of the area while drawing contaminated air up from the center of the area. See Fig. 2.

When multiple air cleaners are installed, the allotted areas to be cleaned should be equal. The air throw in one direction is approximately 55 ft (17m). Air velocity at 90 ft per minute (27m per minute) is considered end of throw.

IMPORTANT

Never hang the air cleaner higher than 16 ft (5m) above the floor.
