Trane CenTraVac™ Water-Cooled Chiller CVHF - 300-500 - 379 - 050S / 080S

Are the readings within the values provided in the general maintenance?

Is the oil level visible in the lower sight glass when the unit is operating?

Sign off on the daily chiller maintenance

Use a non-destructive tube test to inspect the condenser and evaporator tubes

Tube test performed on condenser?

Tube test performed on evaporator?

It may be desirable to perform tube tests on these components at more frequent intervals depending upon chiller application

This is especially true of critical process equipment

Ask your Sales account manager for a copy of engineering bulletin (CTV-PRB024*-EN) for clarification of the role of eddy current testing in chiller maintenance by providing information about eddy current technology and heat exchanger tubing

WARNING: Explosion Hazard! Never use an open flame to detect gas leaks. Use a leak test solution for leak testing.

WARNING: Hazardous Pressures! If a heat source is required to raise the tank pressure during removal of refrigerant from cylinders, use only warm water or heat blankets to raise the tank temperature. Do not exceed a temperature of 150°F. Do not under any circumstances apply direct flame to any portion of the cylinder.

Important: If leak testing is required, contact a Trane Service Agency;

Check purge times and unit performance logs

Submit refrigerant sample for analysis if required

Inspect unit for any signs of refrigerant or oil leakage

Check unit for any loose screws on flange, volutes, or casing

Is the evaporator part of a closed circuit?

If the evaporator is part of a closed circuit, it may not accumulate appreciable amounts of scale or sludge.

Has it been three years since the last cleaning?

Normally, cleaning every three years is sufficient.

Is the evaporator part of an open system, such as air washers?

However, periodic inspection and cleaning is recommended on open evaporator systems, such as air washers.

Evaporator refrigerant temperature sensor (4R10) reading

Is the sensor reading within the normal operating range (0°F to 90°F [-17.8°C to 32.2°C])?

Are the ifm efector® flow detection sensors clean?

Upload a photo of the compressor oil sample sent to the Trane-qualified laboratory
