WARNING! READ BEFORE INSTALLATION
1. GENERAL:
A failure resulting in injury or damage may be
caused by excessive overpressure, excessive
vibration or pressure pulsation, excessive instrument temperature, corrosion of the pressure containing parts, or other misuse.
Consult Omega Engineering before installing
if there are any questions or concerns.
2. OVERPRESSURE:
Pressure spikes in excess of the rated overpressure capability of the gauge may cause
irreversible electrical and/or mechanical
damage to the pressure measuring and containing elements. Fluid hammer and surges
can destroy any pressure transducer and
must always be avoided. A pressure snubber
should be installed to eliminate the damaging
hammer effects. Fluid hammer occurs when
a liquid flow is suddenly stopped, as with
quick closing solenoid valves. Surges occur
when flow is suddenly begun, as when a
pump is turned on at full power or a valve is
quickly opened.
PRESSURE SURGES:
Surges are particularly damaging to pressure
gauges if the pipe is originally empty. To avoid
pressure surges, fluid lines should remain full
(if possible), pumps should be brought up to
power slowly, and valves opened slowly. To
avoid damage from both fluid hammer and
surges, a surge chamber should be installed.
Symptoms of fluid hammer and surge’s damaging effects:
• Digital Gauge exhibits large zero offset.
• Digital Gauge pressure display remains
constant regardless of pressure
• Error code is displayed on screen.
FREEZING:
Prohibit freezing of media in pressure port.
Unit should be drained. (Mount in vertical position to prevent possible overpressure
damage from frozen media.)
3. INSTALLATION:
This procedure requires the use of a 1
1
⁄16˝
(27mm) hex wrench for tightening the instrument to the process connection. Apply
Teflon tape or a suitable sealing compound
to NPT threads of the gauge. Take using the
wrench, tighten 1 turn beyond hand-tight
or until a leak-proof seal has been
achieved.
Caution: Tightening the product by
grasping or putting a tool on the plastic
housing can cause permanent damage to
the product.

The first screen to appear will show all digits
lit up as “5” and the rightmost decimal point
will blink (5 5 5 5.5) unless the custom units

and the decimal point fixed in the previously
chosen position. However, if the custom
units feature has been used previously, then
the digits shall correspond to the last value.
