Trane Split System Cooling Condenser TTA073D

Preparation and Safety Precautions

Ensure all electrical connections are complete before starting the procedure.

Is the compressor access panel installed and manifold hoses routed through refrigerant gauge access holes?

Verify that a qualified licensed electrician is present for handling live electrical components.

Turn on power to the unit and allow the system to run for 5 to 10 minutes to stabilize operating conditions.

Airflow and Refrigerant Charging

Measure airflow across the indoor coil.

Is the airflow measurement within the fan performance data specifications?

Disconnect all electric power, including remote disconnects

Discharge all motor start/run capacitors

Follow proper lockout/tagout procedures

Verify with a voltmeter that all capacitors have discharged

Ensure all connections are tight

Ensure wiring insulation is intact

Disconnect all electric power, including remote disconnects, and discharge all motor start/run capacitors.

Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized.

Verify with an appropriate voltmeter that all capacitors have discharged.

Remove enough panels from the unit to gain safe access to coils.

Ensure not to walk on the sheet metal base to avoid collapse.

Straighten any bent coil fins with a fin comb.

Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing.

Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized.

Verify with an appropriate voltmeter that all capacitors have discharged.

Ensure compressor is not operated or powered while under a vacuum.

Perform all of the monthly maintenance inspections.

Check unit superheat and record the reading in the 'Maintenance Log'.

Ensure only dry nitrogen with a pressure regulator is used for pressurizing the unit.

Confirm no use of acetylene, oxygen, or compressed air for pressure testing.

Verify no use of open flame for gas leak detection.

Pressurize the system through the service valve with dry nitrogen to 200 psi.

Check all field joints for leaks using soap bubbles or other methods

Release pressure and repair leaks if any were found.
