Waterbox Removal and Installation
Important: Only qualified technicians should perform the
installation and servicing of this equipment.
Discussion
This section will discuss recommended 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.
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
with an acceptable working load limit. Refer to the
waterbox weights table.
Note: Refer
to"Torque Requirements and Waterbox
Weights," p. 112
for waterbox weights.
WARNING
Straight Vertical Lift Required!
Failure to properly lift waterbox in straight vertical lift
could cause the eyebolts to break which could result
in death or serious injury from object dropping.
The proper use and ratings for eyebolts can be found
in ANSI/ASME standard B18.15. Maximum load rating
for eyebolts 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.
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.
CDHH-SVX003C-EN
Important: This section contains rigging and lifting
information only for Trane
chillers built in La Crosse. For Trane
CenTraVac™ chillers built outside the
United States, refer to literature provided
by the applicable manufacturing location.
2. The rated lifting capacity of the lifting shackle 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
size for the waterbox lifting hole.
4. Properly connect the shackle to the waterbox. Refer to
the following figure
5. Disconnect water pipes, if connected.
6. Remove hex head bolts.
7. Lift the waterbox away from the shell.
WARNING
Overhead Hazard!
Failure to follow instructions could result in death
or serious injuries.
Never stand below or in close proximity to heavy
objects while they are suspended from, or being
lifted by, a lifting device in case the object drops.
8. Store waterbox in a safe and secure location and
position.
Note: Do NOT leave waterbox suspended from lifting
device.
