1.4 PRECAUTIONS AND RECOMMENDATIONS
Read the entire manual before installing and operating the RheoVac DR system.
Carefully select the best location for installation of the probe(s). Access, clearances, freedom
from standing water, and straight-run should all be considered when selecting probe
locations.
Use reasonable care in handling the probes the sensing components are delica te. Do not
bend the probes, damage the tips, or obstruct the sensing ports. If shipping the unit, make
sure the probes are 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 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 line where a probe is located.
Keep moisture out of the enclosures once all service connec tions are made, make sure the
enclosure lids are tightly closed and all gaskets are in place. Seal all conduit lines.
The RJ45 is the recommended 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 updates. Instrument probes should be
returned to the factory for inspection and calibration service every two years.
