Trane CenTraVac™ Water-Cooled Chiller CVHF - 300-500 - 360 - 050S / 050S

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 the evaporator been cleaned in the last three years?

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

If yes, periodic inspection and cleaning is recommended.

Sign off on the evaporator maintenance

- Shut down the chiller once each year to check the items of Evaporator

1. Inspect for fouling and scaling in tubes

2. Check operation of evaporator water flow sensing device

3. Factory recommendation to eddy current test tubes every three years;

Warning: Equipment Damage! Failure to follow instructions could result in equipment damage

Do NOT use Teflon-based tape or paste on anode; a small amount of liquid sealant (Loctite® 242 or equivalent) may be applied to prevent leakage when installing an anode, but do not apply so much sealant that it prevents the necessary electrical connection between the anode and the waterbox

As needed after draining the waterbox, use a 2-1/2 in. (63.5 mm) wrench to remove/install Trane-supplied waterbox anodes

Inspection of anodes for wear within the first several months of the anodes being placed into service

Enter the observed loss of anode material

Anode has lost 50 percent or more of its original mass

If anode depletion occurs very quickly, consult a water treatment specialist to determine if the anode material selected is correct for the application

Perform Annual oil analysis (follow recommendations)

Clean and lubricate oil system as required

Run oil pump and check differential oil pressure

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 for analysis

Compressor motor winding resistance to ground reading

Did the chiller pass the leak-test?
