Coil Cleaning
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.
Clean the condenser coils at least once each year, or more frequently if the
unit is located in a “dirty” environment. This will maintain proper unit
operating efficiencies. Follow the detergent manufacturer's instructions as
closely as possible to avoid damage to the coils.
To clean the coils, use a soft brush and a sprayer, either a garden, pump-up
type or a high-pressure type. A high-quality detergent, such as “Trane Coil
Cleaner, CHM-0002” is recommended for standard and Copper coils.
Refer to RTAC-SVG01B-EN for maintenance and cleaning procedures coated

NOTE: If the detergent mixture is strongly alkaline (pH value greater than
