Safety First

The location and orientation of the ﬂuid cooler can affect the safety of those

responsible for installing, operating or maintaining the ﬂuid cooler. However,

since SPX Cooling Technologies does not determine the location or orientation

of the ﬂuid cooler, we cannot be responsible for addressing those safety issues

that are affected by the ﬂuid cooler’s location or orientation.
