6700SR Refrigerated Sampler

Reinitialize Controller - The sampler allows you to reset all pro-
gram settings to the settings shipped with the sampler (screen 15).
Reinitializing also clears the memory that stores the sampler’s
event log and module data. Use this option cautiously.
Maintenance Checklist
• Clean the refrigerator interior and exterior periodically.
• Clean the refrigerator’s air filter every 3 months.
• Clean the condenser coil annually.
• Inspect the pump tube for wear. Replace it if necessary.
• Clean the pump tube housing.
• Change the suction line if necessary.
• Clean the bottles, suction line, strainer, and pump tube.
• Check the humidity indicator.
• When the battery warning appears on the display, replace the
controller’s internal battery.
Cleaning Guidelines
Refrigerator
The refrigerator’s exterior may be periodically cleaned with soapy
water using a sponge or nonmetallic brush to keep it free of corro-
sive solutions, grease, oil, etc. After cleaning, it should be wiped
dry. Automotive wax may be applied to the interior and exterior
surfaces to make them easier to clean and more resistant to corro-
sion. Do not direct a hose spray toward the underside or into the
front grill of the refrigerator. The vacuum formed plastic refrigera-
tor interior may also be cleaned with soap and water as necessary.
Because the refrigerator uses a forced-air system, dust and debris
will collect on the condenser coil and surrounding areas. If the re-
frigerator is not cleaned periodically, damage due to overheated
components may result.
Controller
When necessary, clean the controller with warm soapy water. To
prevent moisture damage, always cap the connectors at the back of
the controller tightly. Keep the controller power cable connected, or
replace the protective cap (shipped with the sampler) over the pow-
er source connector.
Make sure the pump drain hole (located on the bottom right-hand
side of the pump, beneath the pump band) is open and free of debris
or buildup.
Avoid using a high-pressure hose to clean the controller, especially
around the control panel. Extreme pressures may force water past
the control-panel seal.
Sample Bottles
The sample bottles have a wide mouth to facilitate cleaning. Wash
them with a brush and soapy water or use a dishwasher. You can
autoclave the glass bottles.
