Maintenance procedures

Inspecting and Cleaning the Drain Pan

Check the condensate drain pan and drain line to ensure that the condensate drains properly at least every six months or as dictated by operating experience.

If evidence of standing water or conden- sate overflow exists, take steps to identify and remedy the cause immediately. Refer to the trouble shooting section of this manual for possible causes and solutions.

￿WARNING

Hazardous Voltage w/Capaci- tors!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout proce- dures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided byTrane or others, refer to the appropriate manufacturer’s literature for allowable waiting periods for discharge of capacitors.Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

Note: For additional information regard- ing the safe discharge of capacitors, see PROD-SVB06A-EN or PROD-SVB06A-FR.

Clean drain pans using the following procedure:

1.Disconnect all electrical power to the unit.

2.Don the appropriate personal protective equipment (PPE).

3.Remove all standing water.

4.Use a scraper or other tools to remove and solid matter. Remove solid matter with a vacuum device that utilizes high efficiency particulate arrestance (HEPA) filters with a minimum efficiency of 99.97% at 0.3 micron particle size.

5.Thoroughly clean the contaminated area(s) with a mild bleach and water solution or an EPA-approved sanitizer specifically designed for HVAC use.

Carefully follow the sanitizer manufacturer’s instructions regarding product use.

6.Immediately rinse the drain pan thoroughly with fresh water to prevent potential corrosion from the cleaning solution.

7.Allow the unit to dry thoroughly before putting the system back into service.

8.Properly dispose of all contaminated materials and cleaning solution.

Inspecting and Cleaning the Fan

Inspect the fan section every six months or more frequently if operating experience dictates. Clean accumulated dirt and organic matter on the fan interior surfaces following the procedure below:

1.Disconnect all electrical power to the unit.

2.Wear the appropriate personal protective equipment (PPE).

3.Use a portable vacuum with HEPA filtration to remove the loose dirt and organic matter.The filter should be 99.97% efficient at 0.3 micron particle size.

4.Thoroughly clean the fan and associated components with an industrial cleaning solution. Carefully follow the cleaning solution manufacturer’s instructions regarding personal protection and ventilation when using their product.

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

6.Allow the unit to dry completely before putting it back into service.

7.Properly dispose of all contaminated materials and cleaning solution.
