NOTE
The meter installation should include a valve
downstream from the meter to prevent water loss
during meter servicing or removal from the line.
NOTE
The system should be installed so that the meter can be
read at a convenient outdoor location. For meters that
are located indoors, a remote reading system is
recommended. This eliminates access problems and
avoids customer complaints concerning strangers
entering the home.
WARNING
Before starting any disassembly operation, the water
line must be depressurized. Removing a meter that is
under line pressure can result in serious personal injury
Ÿ
The meter is a precise measuring device and although robust in design
and construction, should be handled, transported, and installed with
care. The meter should remain within its protective packaging to the point
of installation.
Ÿ
Storage temperatures shall remain within the range of -20°C to +60°C ,
avoiding direct sunlight.
Ÿ
Special fittings and accessories are available to provide easier meter
installation and proper alignment.
Ÿ
All meters should be installed according to local standards or water utility
regulations.
Ÿ
Close the meter's inlet-side valve.
Ÿ
Open a faucet and wait until water flow stops to depressurize the system.
Do not remove the meter until the flow stops.
Ÿ
Check valves and make necessary repairs to shut-off valve or inlet side
valve if necessary.
Ÿ
For proper sealing, use new meter gaskets when changing the meter.
Ÿ
Do not use thread sealant, pipe dope or meter coupling threads, meters
are sealed by the gasket only.
Ÿ
Close the meter's outlet-side valve. Protect the floor below the meter
against potential spills or leaks that could occur. Protect the coupling area
from debris so that the new meter will not be contaminated or damaged.
