Replacing the Electronic Control

Follow this procedure to replace the electronic control:

1. Relieve the pressure.

WARNING

To reduce the risk of serious injury, whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure on page 10.

2. Remove the four screws (3) holding the electronic

control (1) and the metering unit (4) together as

shown in Fig. 6.

3. Remove the battery (see Replacing the Battery

procedure on page 8).

4. Remove all gasket material from the metering unit

(4).

5. Assemble adhesive side of new gasket (2) to

metering unit (4).

6. Replace battery as shown in Fig. 5. (new battery

recommended, see Replacing the Battery proce-

dure on page 8).

NOTE: See Technical Data on page 11 for

recommended battery types.

To avoid pinching the battery wires, install the

battery as shown in Fig. 5, so that the battery wire

is extended to the far side of the battery

compartment.

CAUTION

7. 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 hou-

sing.

8. Install the four screws (3) holding the electronic

control (1) and the metering unit (4) together.

Torque the screws to 15 to 20 in-lb (1.7 to 2.3

N-m) or until no gap exists between 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.
