any contaminants (e.g., fingerprints) on the mirror, the dew forms unevenly and can affect
the accuracy of the reading.
The instrument should be cleaned if visual inspection indicates the chamber is dirty or as
part of the verification process (Section4.1).
4.2.1 CLEANING KIT
The AQUALAB comes with an AQUALAB Cleaning Kit that contains enough cleaning supplies
to clean the instrument for about 1 year. The following supplies are included:
• Spatula (a thin plastic rod)
• Deionized water for cleaning
• Cleaning Solution
• KIMWIPES
®
tissues
• Activated charcoal for removing volatile compounds from the chamber between readings
NOTE: Wash hands with soap and water, and wear clean gloves before starting the cleaning procedure. This prevents
oils from contaminating the cleaning materials, the sample chamber, and the sensors.
4.2.2 AQUALAB 4TEV SPECIAL CONSIDERATIONS
When cleaning an AQUALAB 4TEV, do not to get cleaning solution on the capacitance sensor
filter (Figure73). Repeated exposure of cleaning materials or contaminants to the filter
may cause inaccurate readings. If the filter appears to be contaminated, it may need to
bereplaced.
To replace the capacitance sensor filter, use the following steps:
1. Use a tweezer or small knife blade to pry up the edge of the filter, being careful not to
disturb the sensor beneath.
2. Discard the soiled lter.
3. With clean and gloved hands, gently press a new lter into place.
4.2.3 CLEANING PROCEDURE
The procedure to clean AQUALAB involves washing, rinsing, and drying each area.
NOTE: Isopropyl alcohol can be substituted for the Cleaning Solution.
1. Turn the AQUALAB power OFF.
2. Open the chamber cover to expose the sample chamber and sensors.
3. Clean the sample chamber. The sample chamber consists of all surfaces inside the red
O-ring when the lid is closed.
NOTE: Be extremely careful not to damage the fan blades when cleaning the chamber.
a. Remove any debris that may have collected within or around the sample chamber.
