Installation Requirements
• Make sure that all necessary safety precautions have
been taken. Provide for proper ventilation,
temperature control, fire prevention, evacuation, and
fire management.
• Provide easy access to the appropriate fire
extinguishers for the product. Consult with the local
fire department and state and local codes to make
sure that you are adequately prepared.
• Read this manual as well as the literature provided
in the “Owner’s Information Packet”. If there are any
questions, consult with the full-service distributor or
call the Service Department at Liquid Controls.
• Install the meter and accessories in conformance with
all applicable federal, state, local, construction,
electrical, and safety codes.
• Class 10 meters for LPG must be installed in
accordance with the requirements of ANSI-NFPA 58
in addition to all other state and local codes.
• Before shipment, protective thread caps were placed
in all meter and accessory openings. They should
remain in place until ready to attach piping.
• Prior to meter installation, the entire piping system
should be thoroughly flushed of all debris, with a liquid
that is compatible with the construction of the meter.
• Keep all external surfaces of the meter clean.
NOTE: Always request up-to-date, engineering approved, dimensional drawings before starting any construc-
tion. Do not rely on catalog pictures or drawings which are for reference only. After receiving prints,
check to see that all equipment ordered is shown and that any extra pressure taps, plugs, etc. are
noted and their size specified.
! ! ! ! ! WARNING
All internal pressures must be relieved before disassembly of the meter, strainer, vapor eliminator,
any valves in the system, the pulse output device, or the front and rear covers. LINE PRESSURE
MUST BE 0.0 PSI. See “Meter Maintenance” on Page 15 for the procedures to relieve internal
pressure.
• The meter must always be securely bolted to a
platform or supporting member, regardless of the
mounting position of the meter. Never “hang” a
meter on the connecting pipe.
• Prevent pipe strain or stress from occurring when
making meter or accessory repairs. Pipe strain and
stress occur when the pipes are not supported or
are not aligned correctly to the meter. The weight of
the pipes must always be supported independent
of the meter. This means that the meter and
accessories can easily be removed without affecting
the pipes or the pipe alignment. Never leave any of
the pipes hanging.
• Apply pipe compound to male threads only.
• Install the meter down stream of the pump.
• Position the meter with service in mind. Provide
ample work space. Removing covers can be difficult
when work space is not available. Always supply a
platform or support for the meter mounting.
• A meter is metallurgically designed to be physically
compatible with a given type of liquid, as originally
specified by the customer, and as indicated on the
Serial Number Plate. A meter should not be used
with a liquid different from the liquid originally
specified, unless the physical characteristics and pH
rating are similar and the application has been
checked with Liquid Controls Sales or Engineering.
