METER MAINTENANCE
The only suggested maintenance is to annually remove the meter from the
water line and gently back flush the meter to remove particles that may
have been trapped by the strainer. Back flushing is running the water into
the meter from the outlet side instead of the normal flow direction. If some
unusual evidence of meter performance is observed during maintenance,
please contact the factory.
A broken tamperproof wire & seal indicates the meter has been
disassembled.

1. Flush the line thoroughly after plumbing changes to eliminate the
possibility of foreign contaminants reaching the meter. GPC GPC GPC GPC

3. Using the insulated 18/20 gauge two wire cable provided, connect 200MRS N/A X X X
the reed switch on the register to the meter input leads on the
controlling device. N/O Reed Switch rated at 100 mA, 24V AC/DC.

6. It is not recommended that the meter be run for long periods of
time at the maximum flow rating as excess wear will result and
the life of the meter will be reduced. LPC LPC LPC LPC

8. Protect the meter from freezing and from heat in excess of 120° F.
9. Protect meter from any backflow of water opposite indicated direction
of flow.

■The straight, unobstructed pipe section in front of the meter
should be as follows:
Inlet Path - One Bend = 10 x Diameter of pipe
Valves (check, gate, etc.) = 12 X Diameter of pipe
Two Bends or One Tee and one bend(s) at random =
25 X Diameter of pipe
