After installation is complete and prior to opening the upstream/inlet
water valve ensure that the valve on the downstream/outlet side of the
meter is shut.
Ÿ
In case the main/service shut-off valve is closed, open it slowly to
pressurize the service line to the meter setting. Air in the lines may damage
a meter and other equipment. Water hammer from a quick turn-on can
damage plumbing and appliances or cause a water line rupture.
Ÿ
Slowly open the inlet side valve which will fill the meter with water. Once
the water is flowing fully open the meter inlet valve . Partially open valves
can render the meter inaccurate and lead to low water pressure.
Ÿ
Check for leaks around the meter and connections. Open a
downstream/consumer faucet to allow entrapped air to escape once the
outlet valve is opened. Open the meter outlet side valve slowly to
pressurize the downstream/ consumer side of the system. Turn off the
consumer faucet when normal water flow occurs.
Ÿ
Ensuring that all consumer faucets are shut, observe the low flow detector
in the meter to identify downstream leaks in the consumer's system.
WP Installation
Ÿ
The meter must be installed with the direction of the flow as indicated by
the arrow cast in the meter body.
Ÿ
In order to keep the water meter in good working condition, the pipeline
should be cleared before installation.
Ÿ
A horizontal position with the register face upwards is recommended.
Ÿ
The meter must have 10 diameters straight pipe ahead of the meter and 5
diameters straight pipe after to ensure proper flow through the meter.
Ÿ
The valves must be installed in the front and the back of the water meter.
Ÿ
Attention should be paid that a cold water meter must not be used for hot
water..
Ÿ
It is recommended to install a filter before water meter.
WARNING
The meter can be damaged if subjected to full ow
conditions prior to expelling all the air from the
pipeline
.
