| Maximum safe liquid temperature | 35 °C (95 °F) |
|---|---|
| Maximum storage temperature | 49 °C (120 °F) |
| Maximum operating pressure | Do not exceed limits provided in guide |
Do not exceed the maximum operating pressure or temperature limits, keep gas/vacuum ports open, use proper pressure relief valves, ground electrical connections, avoid hot surfaces, and secure the contactor firmly.
Store the contactors in sealed bags or shrink‑wrap, keep them in the original opaque box, and maintain a temperature below 49 °C (120 °F) with humidity under 60 %.
