Do not clean the controller compartment heater with liquids of any kind.
If water is not sufficient to clean the controller and the pump, disconnect the controller and move the
controller away from the sampler. Allow sufficient time for the controller and pump to dry before the
parts are re-installed and put back into service.
Clean the sampler as follows:
• Refrigerator—clean the condenser fins and coils as needed with a brush or vacuum.
• Sampler cabinet and tray—clean the internal and external surfaces of the sampler cabinet with a
damp cloth and mild detergent. Do not use abrasive cleaners or solvents.
Replace the desiccant
A desiccant cartridge in the controller absorbs moisture and prevents corrosion. Monitor the
desiccant color through the window. Refer to Figure 13. Fresh desiccant is orange. When the color is
green, replace the desiccant.
1. Unscrew and remove the desiccant cartridge. Refer to Figure 13.
2. Remove the plug and discard the spent desiccant.
3. Fill the desiccant tube with fresh desiccant.
4. Install the plug.
