Waterbox Removal and Installation
IImmppoorrttaanntt:: Only qualified technicians should perform
the installation and servicing of this
equipment.
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.

Review mechanical room limitations and determine the
safest method or methods of rigging and lifting the
waterboxes.
1. Determine the type and size of chiller being
serviced. Refer to Trane® nameplate located on
chiller control panel.
IImmppoorrttaanntt:: This section contains rigging and lifting
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 Table
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.

8. Store waterbox in a safe and secure location and
position.
NNoottee:: Do NOT leave waterbox suspended from
lifting device.
