PRECAUTIONS AND RECOMMENDATIONS
Read the entire manual before installing and operating the RheoVac system.
WARNING — Be sure to power up your RheoVac instrument system and probe(s)
for at least 30 minutes before inserting probes into the vent line hot taps. DO NOT
leave probe in vent line without power or when flooding the condenser.
Carefully select the best locations for installation of the probes. Access, orientation,
installation clearances, freedom from standing water, absence of water traps, minimum
required straight-run should all be considered when selecting a probe location.
Use reasonable care in handling the probe — the sensing components are delicate. Do
not bend the probes, damage the tips, or obstruct the sensing ports. If shipping the unit,
make sure the probe is adequately protected from foreign objects and damage; save and
reuse factory provided custom probe protector and shipping boxes.
Use proper input power — it must be between 100 and 250 Vac (nominal 120/240 Vac)
at 50/60 Hz (60 Hz nominal).
Confirm the line and environmental temperature is always within the probe and
electronics ratings — never operate a probe at or subject it to temperatures or pressures
beyond its specified limits. (See SECTION 1.4)
WARNING — Never allow live high temperature steam to flow either direction in
the exhauster line where a probe is located. This can happen if steam jet ejectors
are operated incorrectly.
WARNING — Do not allow the instrument sensors (or separate RS probe) 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 provides analysis and design services to improve condenser
venting and reduce or eliminate entrained liquid water and excess condenser back
Keep moisture out of the enclosures — once all service connections are made, make sure
all gaskets are in place and the enclosure lids are tightly closed. Seal all conduit lines.
Intek recommends using the RJ-45 network connection for all data traffic (as opposed to
serial and 4-20 mA communication).
Intek recommends a service contract to ensure probes are within calibration
specifications and electronics are maintained with appropriate software/hardware
updates. Instrument probes should be returned to the factory for inspection and
calibration service every two years.
Intek recommends the use of condenser diagnostic tools and tutorials provided on
