F118 IN-CEILING MEDIA AIR CLEANER

OPERATION

Local, Federal and professional ventilation engineering standards and codes prescribe minimum ventilation rates to dilute air contamination in specific applications. The ventilation rates usually assume the injection of outdoor air measured as air exchange rate.

Using the F118 Air Cleaner to comply with ventilation requirements is an acceptable alternative to ventilation with outdoor air. However, at least 20 percent of a specified ventilation code rate must be derived from outdoor air. The F118 Air Cleaner filtered and re-circulated air can supply the remaining 80 percent.

Airborne contaminants are always present in the air where contaminant generation occurs. Air cleaning systems and ventilators do not eliminate airborne contaminants; they reduce excessive contaminant accumulation. To eliminate the contamination, the source of contamination must be removed.

The F118 in Ceiling Media Air Cleaner was engineered to improve indoor air quality for commercial and industrial applications. The filters are effective for capturing atmospheric dust, mold spores, smoke, fumes, mists and aerosols. See Fig. 9.

SERVICE

WARNING

Fire or Electric Shock Hazard.

Can cause personal injury or equipment damage. Turn off power source before servicing air cleaner.

IMPORTANT

A very dirty filter reduces air cleaner airflow.

Opening/Closing Grille

IMPORTANT

Use this procedure when opening the grille to pre- vent damage to the cover and prevent ceiling buck- ling.

To open the grille and remove and replace the filters:

1.	Pull apart the spring-loaded plungers to disengage from
	the grille.
2.	Turn the plungers to keep them from closing and reen-
	gaging the grille.
3.	Slide the grille forward toward you. It can travel about
	one inch.

Fig. 9. F118 Air Cleaner operation.

The air cleaner may be operated on high, medium, or low speed, depending on the number of people and activities in the space.

The unit may be used only while people are using the room, or when contaminants from other sources must be removed from the room. And the air cleaner may be operated continuously to prevent buildup of airborne contaminants, even when the room is unoccupied.

The CPZ™ sorbent module collects and holds gas-phase compounds and vapors typically found in commercial and light industrial facilities. These gases and vapors frequently appear as odors that can be annoying and irritating. CPZ™ material extends the maintenance service life.

The minimum recommended air exchange rate is 2.5 times per hour. In a heavily contaminated area, up to 15 air exchanges per hour can be necessary. The factors that determine the rate of air exchange are:

•Generation rates of the various pollutants;

•Concentration level of the pollutants;

•Desired contamination reduction level.

The particle filter collects particles that are not trapped by the pre-filter. The particle filter life is from 6 to 24 months (typically 12 to 24 months). Change modules and filters more frequently in facilities that operate 24 hours a day. When the filter is loaded with contaminants, there is a pulsing sound, and decreasing air quality. Replace the filter when the pulsing sound becomes audible.

IMPORTANT

The filter must be removed and replaced. Washing, vacuuming or reverse air blasting does not clean it.

CAUTION

Equipment Damage Hazard.

Handling can damage the filter media.

Handle only the filter frame.

Do not touch the pleated filter media.

1.Push aside the two spring-loaded support rods that hold the filter frame in place.

2.Rotate the rods; the filter is released and can be removed.

3.With both hands, slide the filter toward you.

4.Place the removed filter in a plastic trash bag and dis- pose of properly.

5.Unwrap and install a new filter.
