Cleaning Porous Surfaces

WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
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

Drain Pans

WARNING
Hazardous Chemicals!
Coil cleaning agents can be either acidic or highly
alkaline and can burn severely if contact with skin
occurs. Handle chemical carefully and avoid contact
with skin. ALWAYS wear Personal Protective Equipment
(PPE) including 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.
WARNING
No Step Surface!
Do not walk on the sheet metal drain pan. Walking on
the drain pan could cause the supporting metal to
collapse, resulting in the operator/technician to fall.
Failure to follow this recommendation could result in
death or serious injury.
The condensate drain pan and drain line must be checked
to assure the condensate drains as designed. This
inspection should occur a minimum of every six months or
more often as dictated by operating experience.
If evidence of standing water or condensate overflow
exists, identify and remedy the cause immediately. Refer
to "Troubleshooting, " p. 81
solutions.
To clean drain pans:
1. Disconnect all electrical power to the unit.
2. Wearing the appropriate personal protective
equipment, remove any standing water.
3. Scrape solid matter off of the drain pan.
4. Vacuum the drain pan with a vacuum device that uses
high-efficiency particulate arrestance (HEPA) filters
with a minimum efficiency of 99.97 percent at
0.3 micron particle size.
5. Thoroughly clean any contaminated area(s) with a
mild bleach and water solution or an EPA-approved
sanitizer specifically designed for HVAC use.
6. Immediately rinse the affected surfaces thoroughly
with fresh water and a fresh sponge to prevent
potential corrosion of metal surfaces.
7. Allow the unit to dry completely before putting it back
into service.
