Model 3120 RAS Getting Started Guide

Maintenance

– Immerse in warm, soapy water—Where stubborn air-borne dirt is present, the filter can be dipped in a 

solution of warm water and mild detergent. After cleaning, rinse the filter in clear water, then let it dry 
completely before returning it to service.

If the air filter is too dirty to clean or if it is damaged, you can order a 
replacement filter from the Universal Air Filter Company. The filter 
part number is 05110026M.

Figure 38. Installing the air filter

Before installing the replacement filter, verify that it is oriented with 
the support crosspieces on the underside, as shown in figure 38.

4. While pressing down on the tab, insert the air filter into the chassis. 

5. After the filter has been inserted, release the tab and gently press the filter forward until it is fully seated in 

the chassis housing.

The RAS requires no calibration.
