Circuit Assembly Replacement
The circuit assembly (Part No. 100005109) contains all of the electronic components. To retain the current
volume information for reentering into a new replacement unit, record the totalized volume and rate informa-
tion before uninstalling the circuit assembly.
CAUTION: Before opening the enclosure, make sure the enclosure is in a well-ventilated area
and avoid breathing fumes that could be trapped inside. Under normal operating conditions,
the lithium battery that powers the MC-II is a sealed unit and poses no hazard when the enclo-
sure is opened. However, a leak in a lithium battery could expel toxic fumes into the enclosure.
If the battery appears to be damaged, adhere to the safety precautions and follow the disposal
instructions provided in Appendix C.
To remove the circuit card, perform the following steps:
1.
Loosen the eight captive screws around the outer edge on the back of the enclosure. The front plate of the
MC-II will fold down, hinging on the plastic retaining straps at the bottom of the enclosure. The circuit
board should now be exposed for servicing.
2.
Remove the four screws located in the corners of the card.
3.
Disconnect the battery, signal cable, and the switchplate.
4.
Reconnect the battery, signal cable, and switchplate to the new circuit assembly..
5.
Secure the new circuit assembly to the faceplate using four mounting screws.
6.
Close the door of the enclosure and secure with eight captive screws around the outer edge of the back of
the enclosure.
