Robinair 22791 Infrared Refrigerant Leak Detector - Manual (Page 8)

Filter Replacement
A filter, located in the tip of the wand, blocks moisture and other
contaminants from the sensor. When this filter becomes wet, it
restricts the flow of air and must be replaced.
To replace the filter:
1. Unscrew and remove the tip of the sensor to expose the white
filter.
2. Remove and discard the filter.
3. Position a new filter in the tip so the round end of the filter is
closest to the tip of the wand.
NOTE: Use only Robinair supplied replacement filters.
Storage
The battery should have a 40%-50% charge during prolonged
storage of a month or longer. The correct storage environment is
critical to battery life.
Storage environment: <80% RH for detector and battery.
For 80% battery recovery:
-4ºF (-20°C) to 140ºF (60°C) less than 1 month
-4ºF (-20°C) to 113ºF (45°C) less than 3 months
-4ºF (-20°C) to 68ºF (20°C) less than 1 year
NOTE: Battery life will be reduced significantly if the battery is
stored with a full charge and/or at high temperatures.
