Trane Odyssey™ Split Systems TTA120 (Condensing Units)

Perform all of the monthly maintenance inspections.

Removal of dust and/or dirt from the unit casing

Removal of corrosion from any surface and repainting

Check the gasket around the control panel door to ensure it fits correctly and is in good condition to prevent water leakage

Inspection of the control panel wiring to ensure that all connections are tight and that the insulation is intact

Note: Condenser fan motors are permanently lubricated.

Check refrigerant piping and fittings for leaks

Inspection of the condenser coils for dirt and debris. If the coils appear dirty, clean them.

Regular coil maintenance, including annual cleaning-enhances the unit's operating efficiency by minimizing: – compressor head pressure and amperage draw; – water carryover; – fan brake horsepower and – static pressure losses.

At least once each year-or more often if the unit is located in a “dirty” environment-clean the evaporator and condenser coils using the instructions outlined below. Be sure to follow these instructions as closely as possible to avoid damaging the coils. To clean refrigerant coils, use a soft brush and a sprayer. Contact your local Parts Center for appropriate detergents.

WARNING: No Step Surface! Do not walk on the sheet metal base. Walking on the base could cause the supporting metal to collapse. Failure of the base could result in death or serious injury.

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

Straighten any bent coil fins with a fin comb.

Remove loose dirt and debris from both sides of the coil with a soft brush.

Mix the detergent with water according to the manufacturer's instructions. If desired, heat the solution to 150° F maximum to improve its cleansing capability.

Pour the cleaning solution into the sprayer.

Spray the leaving-airflow side of the coil first; then spray the opposite side of the coil. Allow the cleaning solution to stand on the coil for five minutes.

Check unit wiring to ensure all connections are tight and that the wiring insulation is intact.

Inspect the condenser coils for dirt and debris. If the coils appear dirty, clean them.

With the unit operating in the cooling mode, check the suction and discharge pressures and compare them with Pressure Curve values in unit Service Facts.

Record these readings on the “Maintenance Log.”
