Routine Maintenance

 WARNING

Hazardous Chemicals!

Coil cleaning agents can be either acidic or highly alkaline. Handle chemical carefully. Proper

handling should include goggles or face shield, chemical resistant gloves, boots, apron or suit as

required. For personal safety refer to the cleaning agent manufacturer’s Materials Safety Data

Sheet and follow all recommended safe handling practices. Failure to follow all safety

instructions could result in death or serious injury.

Cleaning Non-Porous Insulating Surface

If microbial growth on a non-porous insulating surface (closed cell insulation or sheet metal

surface) is observed:

1. Disconnect all electrical power to the unit.

2. Wearing the appropriate personal protective equipment, use a brush for sheet metal surfaces

or a soft sponge on a foil face or closed cell foam surface to mechanically remove the microbial

growth.

Note: Be careful not to damage the non-porous surface of the insulation.

3. Install a block-off to prevent spray from going into a dry section of the unit and/or system

ductwork.

4. Thoroughly clean the contaminated area(s) with an EPA-approved sanitizer specifically

designed for HVAC use.

5. Rinse the affected surfaces thoroughly with fresh water and a fresh sponge to prevent potential

corrosion of the drain pan and drain line

6. Repeat steps 4 and 5 as necessary.

7. Confirm the drain line is open following the cleaning process.

8. Allow the unit to dry thoroughly before putting it back into service.

9. Replace all panels and parts and restore electrical power to the unit.

10. Be careful any contaminated material does not contact other areas of the unit or building.

Properly dispose of all contaminated materials and cleaning solution.

Cleaning Porous Insulating Surface

To clean a porous insulating surface (fiberglass insulation):

1. Disconnect all electrical power to the unit.

2. Wearing the appropriate personal protective equipment, use a vacuum device with a HEPA filter

(99.97 percent efficient at 0.3 micron particles) to remove the accumulated dirt and organic

matter.

Note: Be careful not to tear the insulation surface or edges.

3. Confirm the drain line is open following the cleaning process.

4. Allow the unit to dry thoroughly before putting it back into service.

5. Replace all panels and parts and restore electrical power to the unit.

6. Be careful any contaminated material does not contact other areas of the unit or building.

Properly dispose of all contaminated materials and cleaning solution.
