Trane CenTraVac™ Water-Cooled Chiller CVHF - 300-500 - 360 - 080L / 080L

Proper Water Treatment Required! The use of untreated or improperly treated water could result in scaling, erosion, corrosion, algae or slime

Use the services of a qualified water treatment specialist to determine what water treatment, if any, is required. Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water

Condenser tube fouling is indicated when the approach temperature (the difference between the condensing refrigerant temperature and the leaving condenser water temperature) is higher than predicted

If the annual condenser tube inspection indicates that the tubes are fouled, two cleaning methods— mechanical and chemical—can be used to rid the tubes of contaminants. Use the mechanical cleaning method to remove sludge and loose material from smooth-bore tubes

To clean other types of tubes including internally- enhanced types, consult a qualified service organization for recommendations

1. Follow all instructions in “Waterbox Removal and Installation,” to remove waterbox covers

2. Work a round nylon or brass bristled brush (attached to a rod) in and out of each of the condenser water tubes to loosen the sludge

Shut down the chiller once each year to check the items of Optional Accessories

If applicable, lubricate factory-installed gantries

After the first month of operation, inspect Heresite® or Belzona® coated waterboxes; thereafter, inspect as needed

Inspect and lubricate hinged waterboxes

With water flow sensing option, bleed tubing from waterboxes to transformers

Sign off on the yearly optional accessories maintenance

Review the purge Installation, Operation, and Maintenance manual and follow maintenance and/or inspection items identified

Review overall operation of purge and service as necessary

Sign off on the purge unit inspection

Enter the reading of the evaporator refrigerant temperature sensor (4R10)

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

Are the condenser tubes fouled?

If fouled, clean the condenser tubes

Are the ifm efector® flow detection sensors clean?

If not, clean the sensors using Scotch-Brite® or other non-abrasive material. Do NOT use steel wool.

Upload the comprehensive analysis report of the compressor oil from a Trane-qualified laboratory

- 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;
