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 could 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. Depending upon model type, a unit-mounted starter can weigh up to 750 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 starter unit.
2. 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 connecting the panel to the Z-bracket on the
motor flange.
3. While steadying the starter panel to prevent it from tipping forward, carefully begin removing
the retaining bolts that connect it to the Z-bracket.
a. 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!
Important: 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!
