Meter Door Opening
Material Loss / Air Leak Risks:
Do not open the clean-out door (the door under the upper
DRIVING gear) until preparations have been made to capture
any material to be re-used. Any material present will flow
immediately, possibly in large volume, as soon as the door is
open.
Refer to Figure 57 (which depicts an earlier version of the
meter without the gate handle extension and guards - do not
operate without guards installed)
1.
Pull out on the clamp handle extension (not shown)
until the handles
are just loose.
2. The door normally will swing down on its own. If not,
pull it open by hand.
Meter Door Closing
Make sure the clamp handles are out or down (not up),
or it will not be possible to close the door.
1. Use a clean rag to wipe any residual material from
the face of the elastomer seals on the door, and from
the bottom face of the meter box.
2. Swing the door up into closed position.
3. While holding the door closed, swing the handle
extensions up until the handles are just past vertical.
4. Inspect the door closure for possible air leaks.
Replace any deformed elastomer seal or damaged
latch clamp.
