Trane CenTraVac™ Water-Cooled Chiller CVHF - 1470 - 1340 - 210L / 210L

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

- Lubricate the gantries annually

1. Use ConocoPhillips Gantries MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi-Purpose (blue in color), or equivalent

- Lubricate the hinges annually

1. Use ConocoPhillips MegaPlex® XD3 (gray in color), LPS® MultiPlex Multi- Purpose (blue in color), or equivalent;

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

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

3. Review overall operation of purge and service as necessary;

- Shut down the chiller once each year to check the items of Starter or Adaptive FrequencyTM Drive

2. Check all connections per manufacturer specifications

3. Follow all manufacturer recommendations for starter or Adaptive FrequencyTM Drive (AFD) maintenance

4. Inspect/clean/service the AFD cooling system (water- or air-cooled AFD)

5. Record all applicable starter or starter component settings;

Inspect for fouling and scaling in tubes

Check operation of evaporator water flow sensing device

Factory recommendation to eddy current test tubes every three years
