WARNING — Never operate any instruments at or subject them to temperatures or

pressures beyond the specified limits. (See Section 1.3)

Use reasonable care in handling the RheoVac and PT probes. Do not bend the probes, damage

the tips, or obstruct the sensing ports. If moving or shipping the unit, make sure the probe is
adequately protected from foreign objects and damage during handling and shipping; save and
reuse factory provided custom probe protector and shipping boxes.

Keep the USB memory stick disconnected during normal operations to extend memory lifetime.

All instruments should be serviced on a 1 or 2 year cycle to ensure all instruments are within

specifications and electronics are maintained with appropriate software/hardware updates.

Use the USB stick to retrieve data after the system has been online and flow has been established

for at least 48 hrs. E-mail data to Intek for evaluation.

Intek recommends using the RJ-45 network connection for all data traffic (as opposed to serial

and 4-20 mA communication).

RheoVac probes and PT probes:

WARNING — Be sure to power up your RheoVac probe(s) for at least 30 minutes before

inserting probes into the vent line. DO NOT leave probe in vent line without power or
when flooding the condenser.

WARNING — Never allow live high temperature steam to flow either direction in the

exhauster line where a RheoVac probe is located. This can happen if steam jet ejectors are
operated incorrectly.

WARNING — Do not allow RheoVac or PT probes to come into contact with liquid water,

including water from condenser flooding (hydro testing) and entrained liquid water.
Entrained liquid water is an indicator of poor condenser venting and may be present in
your condenser vent line due to design configuration. See EPRI’s “Air In-Leakage and
Intrusion Prevention Guideline,” TR 1014125. Intek offers analysis and design services to
improve condenser venting and reduce or eliminate entrained liquid water and excess
condenser back pressure.

Recalibration every 2 years: RheoVac probes and PT probes should be returned to the factory

for inspection and calibration service every two years.

Rheotherm CWFF and thermocouple sensor arrays:

WARNING — Ensure cleaning crews do not apply lateral pressure, “cock,” to the cleaning

guns; this can damage epoxy cladded tubesheets and the installed meters.

WARNING Do not attempt to disassemble the meters/sensors – there are no user

serviceable components.

When cleaning condenser tubes, it is recommended to insert projectiles into the CWFF meter.

Inspect the installation on a scheduled basis or as opportunities arise to ensure the epoxy coating

is securely sealing the installed meters/sensors in place. Follow epoxy coating manufacturer’s
(Plastocor, Duromar, etc.) recommendations to touch up coat as required. Intek recommends
annual inspections, as a minimum.
