CARLON METER, INC. • PRODUCT WARRANTY
Carlon Meter, Inc.(hereinafter Carlon or “the company”) warrants products of its manufacture to be free of
defects in material or workmanship. Liability under this warranty extends for twelve (12) months from the
date of purchase. Liability is limited to repair or replacement of any failed product or assembly proven to be
defective in material or workmanship upon manufacturer’s examination. Removal and installation costs are
not included under this warranty. Manufacturer’s liability shall never exceed selling price of the meter or
assembly in question. Carlon disclaims all liability for damage its products caused as the result of improper
installation, maintenance, use or attempts to operate products beyond their intended functionality,
intentionally or otherwise. Carlon is not responsible for damages, injuries or expenses incurred through the
use of its products. The above warranty is in lieu of all other warranties, either expressed or implied. No
agent of the company is authorized to alter or otherwise revise this warranty.
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

time at the maximum flow rating as excess wear will result and
the life of the meter will be reduced. LPC LPC LPC LPC
