CAUTION
• O-rings should be replaced if meter is disassembled after it has been
in service.
• Serious property damage and great personal injury could occur as
the result of a meter misused or used in an unsuitable application.
CLEANING
Carefully remove the flowmeter from piping system. Remove the 4
screws on each side holding the side plates on. Remove the 4 screws
on each side holding the front and rear shields on. Remove the side
plates and shields. Carefully remove the glass meter tube from the end
fittings. Be sure to not let the internals fall out. Use caution when re-
moving the glass meter tube. Do not allow float to fall out. Float dam-
age may result in inaccuracy. All necessary instrument components are
now fully accessible for cleaning with a bottle brush and appropriate
mild soap solution*. Before the meter is reassembled, inspect all parts
for damage. O-rings should be replaced during meter maintenance
and cleaning.
*Do not use cleaning agents that will damage float, tube or o-rings.
To reassemble, install the glass meter tube back onto the end fittings.
Reinstall the side plates and shields. Tighten the 4 screws on each side
and front and back. Reinstall the instrument into the plumbing system
after removing the old teflon tape (with a wire brush) and replacing
with fresh teflon tape.
Meters should be cleaned with a mild soap solution. This will be an
effective cleaner of rust stains. Caution must be used so that materials
of construction are not damaged by cleaning solutions. Hard water
deposits can be removed with 5% acetic acid solution (vinegar).
REPAIR
7459 meters that require repair should be sent to the factory. Please
call for a Return Merchandise Authorization (RMA) number and return
instructions.
WARNING:
Pressure and temperature ratings are based on a study of the engi-
neering data for particular materials used in construction and on the
design of individual models. This information is supplemented by
destructive test results. Meters with stainless enclosures must never be
operated without shields securely in place. Meters exposed to difficult
environments such as those created by certain chemicals, excessive
vibration or other stress inducing factors could fail at or below the
suggested maximums. Never operate meters above pressure and
temperature maximums. It is strongly recommended that all meter
installations utilize an appropriate pressure relief valve and/or rupture
disc. The pressure settings and locations of these devices should be
such that meters cannot be over pressurized. Meter failure could
result in damage to equipment and serious personal injury. Always
use suitable safety gear, including OSHA approved eye protection
when working around meters in service. We are happy to pass along
chemical compatibility information that has been published by the
manufacturer’s of raw materials used in our products; however, this
information should not be construed as a recommendation made by
King Instrument Company, Inc. for a specific application.
