1.17 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 “Shutdown” on page 3-34 if the unit is to be stored after being used. Refer to
“Operation” on page 3-19, of this manual for operating instructions.
