  foreach($formatUnits->NewDataSet->Table as $unit)
   {
    echo $unit->iDefLeaseNum;
    echo $unit->sTypeName;
   }

Store the value and check if it exists before outputting it.

$arr = array();
foreach($formatUnits->NewDataSet->Table as $unit){
    if(! isset($arr[$unit->sTypeName]) ){
        $arr[$unit->sTypeName] = $unit->iDefLeaseNum;
        echo $unit->iDefLeaseNum;
        echo $unit->sTypeName;
    }
}
