1.8 Storage
If the leak detector is not used immediately, it can be stored as received without special
precautions. A dry, relatively dust-free area is preferred. The required environmental
conditions for storage are:
❑
0% to 95% relative humidity, non-condensing
❑
–30 °F to 150 °F (–34 °C to +65 °C) ambient temperature
Refer to Section 3.7, “Shutdown” on page 3-17 if the unit is to be stored after being used.
Refer to Section 3, “Operation”, of this manual for operating instructions.
