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

WARNING: Hazardous Voltage w/Capacitors!

Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

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.

NOTICE: Check Purge Run-Time for Unit Hermetic Integrity!

Failure to follow instructions below could result in chiller damage.

If frequent purging is required, monitor purge pumpout rate, and identify and correct source of air or water leak as soon as possible to prevent moisture contamination caused by leakage.

NOTICE: Do Not Use Non-Compatible Parts or Materials!

Use of non-compatible parts or materials could result in equipment damage.

- 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;

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.

Normally, cleaning every three years is sufficient.

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

Operate the tang operators manually and check for any abnormalities

Drain contents of the rupture disk and purge discharge vent-line drip-leg into an evacuated waste container

Do this more often if the purge is operated excessively

Apply oil to any exposed metal parts to prevent rust

- The replacement schedule for the optional zinc or magnesium anodes can vary greatly with the aggressiveness of the water that is in the system

- Some sites could require anode replacement every two to three months while other sites may require anode replacement every two to three years

1. Trane recommends inspection of anodes for wear sometime within the first several months of the anodes being placed into service

2. If the observed loss of anode material is small, then the interval between subsequent inspections can be lengthened

3. Replace the anode and/ or shorten the inspection interval if the anode has lost 50 percent or more of its original mass

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

Failure to follow instructions could result in equipment damage
