Trane CenTraVac™ Water-Cooled Chiller CVHF - 350-570 - 588 - 050L / 080L

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

2. Clean and touch-up painted surfaces as needed

3. Repair deteriorated, torn, or missing insulation;

- 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

- Check chiller for normal operation

1. Condenser pressure is dependent on condenser water temperature, and should equal the saturation pressure of the refrigerant at a temperature above that of leaving condenser water at full load

2. Normal pressure readings for ASME condenser exceed 12 psig (82.7 kPaG)

3. Oil tank pressure: -9 to -6 psig (-62.1 to -41.4 kPaG). Discharge oil pressure: 7 to 15 psig (48.3 to 103.4 KPaG)

4. Approximate Evaporator Pressure: 6 to 9 psia (41.4 to 62.1 kPaA) / -9 to -6 psig (-62.1 to -41.4 kPaG)

5. Approximate Condenser: Pressure(a) , (b) 17 to 27 psia (117.2 to 182.2 kPaA) / 2 to 12 psig (13.8 to 82.7 kPaG) (standard condenser)

6. Oil Sump Temperature Unit not running: 140°F to 176°F (60.0°C to 80.0°C)

7. Oil Sump Temperature Unit running: 95°F to 162ºF (35.0°C to 72.2°C)

8. Oil Sump Differential: Oil Pressure(c) 18 to 22 psid (124.1 to 151.7 PaD)

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

1. Inspect for fouling and scaling in tubes

2. Check operation of condenser water flow sensing device

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

- Lubricate the vane control linkage bearings, ball joints, and pivot points

- Lubricate vane operator tang O- rings

- Lubricate the oil filter shutoff valve O-rings;
