CVGF Waterbox Removal and Installation
Introduction
The purpose of this bulletin is to communicate waterbox weights, recommended con-
nection devices, and connection and lifting arrangements for CVGF gear- driven cen-
trifugal chillers.
Important
Only qualified technicians should perform the installation and servicing of equipment
referred to this bulletin.
Discussion
This bulletin 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 the of water box.
• It is the responsibility of the person(s) providing and using the rigging and lifting
devices to inspect these devices to insure 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.
Procedure
WARNING
Heavy Objects!
Each of the individual cables (chains or slings) used to lift the waterbox must be capa-
ble of supporting the entire weight of the waterbox. The cables (chains or slings) must
be rated for overhead lifting applications with an acceptable working load limit. Failure
to properly lift waterbox could result in death or serious injury.
WARNING
Eyebolts!
The proper use and ratings for eyebolts can be found in ANSI/ASME standard B18.15
or in European standard EN1677-1 and EN ISO 3266. Maximum load rating for eye-
bolts are based on a straight vertical lift in a gradually increasing manner. Angular lifts
will significantly lower maximum loads and should be avoided whenever possible.
Loads should always be applied to eyebolts in the plane of the eye, not at some angle
to this plane. Failure to properly lift waterbox could result in death or serious injury.
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 lo-
cated on chiller control panel.
Important: This bulletin contains rigging and lifting information for Trane CVGF
gear-driven centrifugal chillers built in Taicang China only. For Trane chillers built out-
side China, refer to literature provided by the applicable manufacturing location.
2. Select the proper lift connection device from Table 15. The rated lifting capacity of
the selected lift connection device must meet or exceed the published weight of the
waterbox.
3. Insure the lift connection device has the correct connection for the waterbox. Exam-
ple: thread type (coarse/fine, English/metric). Bolt diameter (English/metric).
4. Properly connect the lift connection device to the waterbox. Refer to Figure 21. In-
sure lift connection device is securely fastened.
