Dimensions and Weights

Assembly

1. The water meter should be installed in a position where there is clean and dry and no direct sunshine or pollution or drowning.

2. The water meter should be installed horizontally, and the LCD should be upward.

3. Water flow must go with the same direction as indicated on the body of the water meter.

4. When assemble, the valve in front of water meter should be closed.

5. When assemble, the water meter should be covered to prevent from damage.

6. The water meter should be connected to the couplings first, and not directly to the water pipe.

Extra parts include couplings and nuts.
