Maintenance

Refrigerant Charge

WARNING

Contains Refrigerant!

System contains oil and refrigerant and may be under positive pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use non-approved refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage.

The refrigerant charging procedure for Trane centrifugal chillers is:

1.If water is present in the tubes, break machine vacuum with refrigerant vapor, or circulate water, to avoid tube damage.

2.Always use refrigerant compatible hoses or copper-tubing with self- sealing connections or shut-off valves.

3.Transfer the refrigerant using one of the following (listed in order of preference):

a.An approved Trane low- pressure refrigerant recovery and recycle unit.

b.The available pressure differential.

c.Gravity. (Use a return vent line to refrigerant drums to equalize pressure.)

5.Do not use dry nitrogen to push refrigerant into the chiller as was common practice in the past. This will contaminate the charge and require excessive purging, which will result in unnecessary release of refrigerant.

6.Weigh in the proper charge.

7.Use recovery and recyle unit or vacuum pump to evacuate hoses; discharge outdoors.

8.If refrigerant is supplied in new returnable cylinders, be sure and refer to General Service Bulletin CVHE-SB-48B for information on returning cylinders. This service bulletin is available at the nearest Trane office.

Depending on the chiller duty, contact a qualified service organization to determine when to conduct a complete examination of the unit to discern the condition of the compressor and internal components.

Note: If your chiller is covered by a Trane extended warranty, the terms of that warranty may require that the procedures listed in the Periodic Maintenance section of this manual be followed for your extended warranty to remain in force. The terms may also require that the chiller be inspected by a Trane authorized warranty agent every

4-years or 40,000 operating hours, whichever occurs first. This inspection will include, at a minimum, a review of the annual inspection checklists and the daily operating logs, as well as performance of a leak test and a general inspection of the chiller. The owner is then required to follow the recommendations made as a result of this inspection at the owners expense.
