AQUALAB VSA

• KIMWIPES

tissues

• Activated charcoal

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.

5.2.2 CLEANING PROCEDURE

The procedure to clean AQUALAB VSA involves washing, rinsing, and drying each area. Do

not get cleaning solution on the capacitance sensor filter. Repeated exposure of cleaning

materials or contaminants to the filter may cause inaccurate readings and the filter will need

to be replaced (Section5.3).

NOTE: Isopropyl alcohol can be substituted for the Cleaning Solution.

1. Turn the AQUALAB VSA 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

orange 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.

b. Wrap a new tissue around the end of the spatula and moisten it with cleaning solution.

NOTE: Do not dip used tissue into the cleaning solution as the cleaning solution will become contaminated.

c. Clean upper chamber, O-ring, and all surfaces of the sample block within the orange

O-ring. Replace the tissue if it becomes too dirty during this process.

d. Clean lower block with a fresh KIMWIPES tissue. Clean the entire block surface.

e. Repeat steps b through d using a new KIMWIPES tissue moistened with

deionized water.

f. Repeat steps b through d using a new, dry KIMWIPES tissue to remove any moisture

remaining from the cleaning.

NOTE: Do not reuse tissues.

4. Clean the mirror.

a. Wrap a new KIMWIPES tissue around the end of the spatula and moisten it with

cleaning solution.

b. Gently swipe the moistened tissue across the mirror once. A single swipe is usually

sufficient to remove contaminants.

c. Repeat steps a and b using a new KIMWIPES tissue moistened with deionized water.

d. Repeat steps a and b using a new, dry KIMWIPES tissue to remove any moisture

remaining from the cleaning.

e. Visually inspect the mirror for cleanliness. Clean again if necessary.
