Distributor Test
The distributor test is provided for factory personnel to verify the
distributor’s position as it rotates through the 24 positions.
(screens 12 through 14). The distributor arm flexes slightly when
it contacts the stop, and the sampler measures this flexure. The
sampler uses this measurement to position the arm accurately
over each bottle.
Reinitialize Controller
The sampler allows you to reset all program 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
Inspect the pump tube for wear. Replace it if necessary.
Clean the pump tubing 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
Controller, Top Cover, Center Section, Retaining Ring, and Tub
Clean the top cover, center section, retaining ring, and tub with
warm soapy water or by spraying them with a hose. 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.
When cleaning the controller and top cover, cap the connectors at
the back of the controller tightly. Keep a power source connected
to the power-source connector, or replace the protective cap
(shipped with the sampler) over the power source connector, to
protect the pins from moisture damage. 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.
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.
Suction Line, Pump Tube, and Discharge Tube
Clean the suction line, pump tube, and discharge tube by placing
the end of the suction line in a cleaning solution and pumping it
through the delivery system. Rinse with clean water. If these
items are severely contaminated, discard them. For critical
sampling applications, refer to Cleaning Protocols for Priority
Pollutants.
Strainer
Clean the strainer with a brush and soapy water.
