REPLACING THE INTERNAL PUMP
To replace the internal pump:
1. Turn OFF the analyzer (this is important to avoid potential for contamination
of the measurement cell).
2. Remove the top cover of the analyzer.
3. Locate the vacuum pump and using snips, remove the zip ties that secure
the four hoses that connect to the pump (two on each side)
(It may be a good idea to mark the tubes with color codes to be sure they are
reconnected properly).

5. Remove the four screws that hold the pump/bracket assembly to the bottom
of the chassis.
6. Disconnect the power connector labeled “pump” located about 4 inches
down the black/red cable coming from the top of the pump.
