Mechanical Removal Of The Existing Remote-Mounted Starter; Mechanical Removal Of The Existing Unit; Drive - Trane CVHE Installation Instructions Manual

Installation
Note: The existing Z-bracket and transition cover will
be reused and do not need to be removed
unless greater access is required to the motor
terminals during drive installation.
4. Remove the bolts securing the bottom of the starter to
the brackets on the evaporator.
5. Carefully remove the starter panel from the chiller and
set it down in a safe location.
Important:
• Do not cut off the starter panel brackets that are welded
to the evaporator shell as they will be reused!
• Do not discard any of the nuts, bolts, washers, or the
angle-iron clips that were used to attach the starter
panel tabs to the evaporator bracket as they will all be
reused!
Mechanical Removal of the
Existing Remote-Mounted Starter
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping
and possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. An AFDH cabinet assembly is
top heavy. Test lift unit approximately 24 inches to
verify proper center of gravity lift point. To avoid
dropping of unit, reposition lifting point if unit is not
level.
Notes:
• Due to the number of starter model types that can exist,
the possible remote-mounting configurations (i.e. wall
mounted, stand mounted, floor mounted, etc.) and the
number of possible variations of each mounting
configuration, it is not possible to provide specific
detailed instructions for the correct mechanical
removal of any one particular type of remote-starter.
For each facility that has a remote-mounted starter to
remove, it is the responsibility of the technicians
assigned to perform this task to determine the tools
24
and equipment needed, and to identify the correct
procedures to follow to safely remove the starter.
• On some existing starters, lifting tabs are spot-welded
to the enclosure. These welds can break if not lifted
straight up. To ensure a safe lift, Trane recommends
drilling a hole and bolting the tabs to the enclosure to
ensure a safe lift.

1.0/1.5 Adaptive Frequency Drive
WARNING
Heavy Objects!
Only attach cables (chains or slings) to the designated
lifting points. Each of the cables (chains or slings) used
to lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift. Other lifting arrangements may cause
equipment or property-only damage. Failure to properly
lift unit could result in death or serious injury.
WARNING
Improper Unit Lift!
Most unit-mounted starter designs tend to be top
heavy. Test lift unit to an approximate height of no
greater than 24 inches to verify proper center of gravity
lift point. To avoid dropping the unit, reposition lifting
point if unit is not level. Failure to properly lift unit
could result in death or serious injury or possible
equipment or property only damage.
1. Isolate the LiquiFlo drive water-side with isolation
valves.
2. Cut and cap the LiquiFlo drive water-side connections.
3. Depending upon model type, a LiquiFlo drive can
weigh up to 970 pounds.
a. Verify that the intended lifting device and rigging
has the capacity to safely handle the load before
hooking up to the designated lifting points on the
LiquiFlo drive.
Note: On some existing LiquiFlo drives, lifting tabs
are spot-welded to the enclosure. These welds
can break if not lifted straight up. To ensure a
safe lift, Trane recommends drilling a hole and
bolting the tabs to the enclosure to ensure a
safe lift.
4. Using safe lifting practices, slowly begin taking up the
slack in the rigging.
a. Tension the rigging only to the point that is
necessary to take up enough of the weight of the
starter panel to enable loosening the bolts
