Before each use:
• Inspect the pump. Service as necessary.
• Inspect the pump housing and rollers.
• Clean or replace the wetted parts (bottles, suction line,
strainer, pump tube, and discharge tube).
• Clean the sampler as necessary.
Inspect the pump before each use. Inspections are especially
important when pumping large sample volumes over long
distances or when the sample liquid contains a high percentage
of suspended or abrasive solids. Pumps in need of service might
experience performance problems such as:
• Faulty liquid detection
• Inaccurate sample volumes
• The sampler will not pump any liquid
• Pump jams.
To inspect the pump:
1. Press the On/Off button to place the sampler controller in
the Standby state. This ensures that the sampler will not
attempt to operate the pump.
