mended
.
4. Extreme care must be taken when installing
the meter. Pipe strain or over tightening meter
connections can cause meter damage.

body on the same side as the groove on the body
(refer to diagram).
2. Lightly rotate the rotors (Item 4) by hand (they must
rotate freely).
3. Install o-ring (Item 5).
4. Replace the meter cap (Item 2).
