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.
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 below the probe and electronics
ratings
never operate a probe at or subject it to temperatures or pressures beyond its
specified limits. (See Section 1.3)
. .
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’s RS sensor (or separate RS probe) to come
into contact with liquid water, water mist, or fog – these conditions may be present in
your condenser vent line due to design configuration. The RS sensor measures relative
saturation up to 100% but may fail under the above wet condition. Intek provides design
services to improve condenser venting and reduce or eliminate entrained liquid water and
excess condenser back pressure.
Keep moisture out of the enclosures once all service connections are made, make sure the
enclosure lids are tightly closed and all gaskets are in place. Seal all conduit lines.
. .
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 unpowered or when flooding the condenser.
