Recommended Maintenance and Annual Inspections

Regarding any recommended maintenance procedures or annual inspections, we

suggest any device containing probes should be inspected on an annual basis for

contaminated probes and wire secure terminations.

Caution: Before proceeding, follow any and all plant lock out - tag out procedures

required. Verify that all power is turned off to the probes. If under pressure, the

equipment should be isolated, or the boiler should be shut down before

proceeding with the installation. Open drain valve to eliminate any trapped

pressure. All inspection and installation steps should be performed by a qualified

technician and should be executed in accordance with all applicable national and

local codes.

With no pressure or elevated temperature, beyond ambient conditions, at least

one probe should be removed for inspection. Ideally, for devicescontaining

multiple probes, we suggest removing one probe from an upper indication location

(normally in steam area) and one probe from a lower indication location (normally

in water area) for inspection. If any probes display signs of contamination, they

can be cleaned with a mild detergent and re-installed using a new sealing gasket,

if applicable. Refer to the attached IOM # E189-A for additional details. If a probe

exhibits and contamination across the length of the insulator, which cannot be

easily cleaned, the probe should be replaced.
