Intek RheoVac 950A - Manual (Page 8)

x Check installation clearance. Each transducer probe is approximately 3 feet (0.9m) long
and the hot tap assembly is approximately 13 inches (0.33m) long, therefore, allow
minimum clearance of 4 feet (1.3m) for probe installation. Be sure there are no
obstructions around the vacuum line that will interfere with probe insertion. Figure 3
shows the proper insertion angle.
THIS ORIENTATION IS IMPORTANT FOR
PROPER OPERATION.

x It is recommended that only Intek supplied hot taps be used. The hot tap length affects
the insertion depth of the probe and must be accounted for; likewise, the proper port
clearance for the probe’s maximum diameter.
x Observe the selected sites; check for ease of access. They should be convenient for the
removal and replacement of probes at any time for service without ladders, building
scaffolding or waiting for plant shutdown.
x Check operating conditions. The temperature and pressure limits (see TECHNICAL
SPECIFICATIONS; SECTION 1.4) of the unit should be checked to ensure compatibility
with your application.
x Gases in the air removal line should be free of liquid water, mist or fog. Wetness in the
line will result in erroneous readings from the instrument and can damage sensors. If wet
conditions exist in the air removal line, there is either air removal section damage or
design flaws which adversely affect condenser performance. Consult Intek for assistance
in evaluating the severity of the problem and possible remedies.
