Coils
• Coils should be inspected semi-annually and cleaned as required.
• Check for bent or damaged coil fins and repair as necessary. Use a coil fin comb if the coil
fin is bent or deformed and is repairable.
• Check all refrigerant lines for vibration isolation and support as necessary.
• Check all piping for signs of leaks.
• Check for condensation, water spot, piping insulation damage, frost or other visual sign of
wear or damage.
• Periodic inspection of the coil for signs of corrosion and for leaks is recommended.
• Repair and replacement of the coil and the connecting piping, valves, etc., should be
performed by a qualified individual(s).
Coil Cleaning
• Comply with EPA and OSHA regulations when cleaning.
• Clean the coil in the direction of the airflow so that foreign material will be washed out of the
coil rather than pushed further in.
• Be sure to carefully read and follow the cleaning fluid manufacturer’s recommendations
before using any cleaning fluid.
• Using a brush (non-metallic), clean the coil fins of all debris that will inhibit airflow. This can
also be done with compressed air or with a commercial coil cleaner.
CAUTION: Caution should be exercised in selecting the cleaning solution
as well as the cleaning equipment. Improper selection can result in damage
to the coil and/or health hazards.
Piping
• Clean off any dust or dirt depending on space conditions.
• Check for any piping buckling or deforming from original position. Repair as needed.
• Check for any abnormal vibrations. Secure as needed.
Water/Glycol Cooled System
• Check the glycol level.
• Check glycol concentration to job site requirement.
• Check water quality to your design requirements and to your local and national codes.
• Check flow rate.
• Check water regulating valve and other water components for leaks or damage. Repair as
needed.
• Check the water Y-strainer. Clean as needed.
