6.5 Replacing Battery Pack

WARNING: Substitution of batteries or other components may compromise the intrinsic safety of the instrument.

Replacing the battery pack is accomplished by removing the two screws holding the sensor end-cap of the instrument housing. A 2 mm allen key is required. Slide the battery pack out and disconnect it from the PCB connector.

CAUTION: the battery pack cable has a locking connector. The center tab must be pushed down before the connector can be removed.

Connect the new battery pack to the PCB and slide the battery pack into the instrument housing. See figure 9.

CAUTION: Be sure to properly install the gasket when re-assembling the instrument. The best technique is to thread the screws most of the way in. Install the gasket, then tighten the screws.

CAUTION: Be sure that all wires and tubing will not be pinched or stressed when sensor end cap is replaced.

6.6 Replacing Internal Pump

Replacing the internal pump is accomplished by removing the two screws holding the sensor end-cap of the instrument housing. A 2 mm allen key is required. Slide the internal pump out and disconnect it from the PCB connector and the tubing from the pump.

CAUTION: the internal pump cable has a locking connector. The center tab must be pushed down before the connector can be removed.

CAUTION: Be sure that all wires and tubing will not be pinched or stressed when sensor end cap is replaced.

For instruments with s/n 0700 and above: Connect the new pump to the PCB and tubing.

For instruments with s/n 0699 and below:

Connect the new pump to the PCB and tubing. Pump IN port is indicated on the pump. Attach pump to bracket. See figure 9a.

Pump IN port is indicated by arrow. See figure 9.
