do not remove the metal cover of the metering unit
(see Fig. 5). There are no user-serviceable parts
inside.
Follow this procedure to replace the battery:
1. Relieve the pressure.
WARNING

are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
2. Remove the four screws (3) holding the electronic

5. Install the electronic control (1) to the metering unit
(4), aligning the longer screw boss on the meter
housing with the counterbore in the plastic hous-
ing.
6. Install the four screws (3) holding the electronic

control and the metering unit.
Closing the gap between the electronic control and
the metering unit is very important; it ensures that
no moisture can enter the electronics.
