1.
Flush the line thoroughly after plumbing changes to eliminate the
■
Straight unobstructed pipe section upstream of meter as follows:
possibility of foreign materials damaging the meter.
Inlet Path - One Bend = 10 X Diameter of Pipe
Valves (check, gate, etc.) = 12 X Diameter of Pipe
2.
Operating pressure is 30 to 150 psi.
Two bends or one tee and one bend or bends at random =
25 X Diameter of Pipe
3.
Install meter horizontally with the register facing up and the inlet
port facing the supply water line.
■
Straight unobstructed pipe section downstream of meter =
5 X Diameter of Pipe
4.
It is recommended that if there is any possibility the water supply
contains foreign materials, a
Carlon
strainer be installed between
the supply and the meter.
5.
It is not recommended that the meter be run for long periods of
time at the maximum rating as excess wear will result and the
life of the meter will be reduced.
6.
To reduce potential harmful effects to equipment from water
hammer caused by quick closing valves, it is suggested that you
purchase and install a
Carlon
slow-closing solenoid valve.
7.
Protect the meter from freezing and from heat in excess of 105° F.
8.
Protect meter from any backflow of water opposite indicated
direction of flow.
9.
For outdoor installation, protect the meter from direct exposure
to the elements.
10.
Connect the terminals on the register contact head to the meter
input leads on the controlling device. The N/O reed switch is rated
for a maximum of 10 amps at 250V AC. Note GPC (Gallons Per
Contact) setting to determine frequency of operation.
