The sampler has a safety interlock that prevents the pump
from operating when the pump housing band is open. DO
NOT tamper with the pump housing and band. The pump is
extremely powerful. The pump can injure you severely if the
sampler activates the pump while you are working on it.
Place the sampler controller in the Standby state before
opening the pump housing.
2. Refer to Figure 5-1. Release the latch (G) securing the
metal pump housing band (J).
3. Swing the pump housing band away from the pump
housing.
4. Inspect the following:
a. Pump tube – Look for excessive wear caused by the
pump rollers and for cracks along the sides of the tube.
Cracks might not be apparent unless you flex or
squeeze the tubing. If cracks or excessive wear are
evident, replace the pump tube (Section 5.1.2).
