Procedure

WARNING
Heavy Objects!
Failure to properly lift waterbox could result in death or
serious injury. Each of the individual cables (chains or
slings) used to lift the waterbox must be capable of
supporting the entire weight of the waterbox. The
cables (chains or slings) must be rated for overhead
lifting applications w ith an acceptable working load
limit. Refer to Table 24, p. 99
Review m echanical room lim itations and determ ine the
safest m ethod or m ethods of rigging and lifting the
waterboxes.
1. Determ ine the type and size of chiller being serviced.
Refer to Trane nam eplate located on chiller control
panel.
Im port ant : This literature contains rigging and lifting
inform ation only for Trane CTV chillers built
in La Crosse. For Trane CTV chillers built
outside the United States, refer to literature
provided by the applicable m anufacturing
location.
2. The rated lifting capacity of the lifting shackle m ust
m eet or exceed the published w eight of the waterbox.
Verify the waterbox w eight from the latest published
literature.
3. Ensure that the lift connection device has the correct
size for the waterbox lifting hole.
4. Properly connect the shackle to the
waterbox.Figure 54, p. 98
