INSTALLATION INSTRUCTIONS
Remember that you are installing an instrument. Adapters and fittings
should be tightened only enough to prevent leaking. Over tightening
may damage the o-ring seals and threaded fittings.
Never hold the meterbody with pliers or similar tools that may scratch.
Never allow the flowmeter to support the weight of related pipe or
tubing.
Be certain the meterbody is properly aligned with existing plumbing.
Misalignment will put excessive stress on the meterbody and may
result in damage and a decrease in the maximum pressure. If in doubt
regarding proper plumbing procedures, consult a licensed plumber.
The flowmeter must be installed in an exact vertical plane to ensure
accuracy.
Polysulfone is adversely affected by ultraviolet light. Protect the
flowmeter from direct sunlight.
Always use teflon® tape thread sealant. DO NOT use pipe dope
compounds as these products may cause crazing and cracking on the
meterbody.
Do not use solvent based glued (such as PVC cement) while the
flowmeter is fully installed. When using these glues, remove the
meterbody until the glue has cured. Then purge the system before
installing the unit.
Never attempt to solder brass fittings while the flowmeter is fully
installed. The heat required for soldering can damage the flowmeter.
Caution should be exercised when using ball type valves. In some
cases when the valve is opened the float can slam to the top of the
meter causing damage. This “Water Cannon” effect is actually
exceeding the maximum pressure and is not covered under warranty.
Your flowmeter had been designed to be virtually maintenance free.
Should your unit need occasional cleaning, use a mild soap and soft
bottle brush.
Be sure to note the floats “UP” position before disassembling the meter.
