waterboxes.
1. Determine the type and size of chiller being serviced. Refer to Trane® nameplate located on chiller control panel.
Discussion
This section will discuss recommended hoist ring/ clevises and lifting. Proper lifting technique will vary based on mechanical room layout.
• It is the responsibility of the person(s) performing the work to be properly trained in the safe practice of rigging, lifting, securing, and fastening of the waterbox.
• It is the responsibility of the person(s) providing and using the rigging and lifting devices to inspect these devices to ensure they are free from defect and are rated to meet or exceed the published weight of the waterbox.
• Always use rigging and lifting devices in accordance with the applicable instructions for such device.

information only for Trane CenTraVac
™ chillers built in La Crosse. For Trane
CenTraVac ™ chillers built outside the
United States, refer to literature provided by the applicable manufacturing location.
2. Select the proper lift connection device from
26, p. 91 . The rated lifting capacity of the selected
lift connection device must meet or exceed the published weight of the waterbox. Verify the waterbox weight from the latest published literature.
3. Ensure that the lift connection device has the correct connection for the waterbox (e.g., thread type [course/fine, English/metric] and bolt diameter
[English/metric]).
4. Properly connect the lift connection device to the waterbox. Refer to the following figure and ensure that the lift connection device is securely fastened.
Install hoist ring on to the lifting connection on the waterbox. Torque to 100 ft·lb (135.6 N·m) for 3/4-in.
(19.05-mm) threaded connections and 28 ft·lb
(38.0 N·m) for 1/2-in. (12.7-mm) threaded connections.
5. Disconnect water pipes, if connected.
6. Remove waterbox bolts.
7. Lift the waterbox away from the shell.

Reassembly
Once service is complete, the waterbox should be reinstalled on the shell following all previous procedures in reverse. Use new O-rings or gaskets on all joints after thoroughly cleaning each joint.
