Low megohm on heating elements with epoxy
or hermetic seals cannot be serviced in the field.
Typical resistance values when sealed are 1000
megohm or greater.
26.0 Check that all connections are tight.
27.0 If a thermostat is provided, verify that it is operating properly
by cycling it and verifying cutout.
28.0 Perform an IR test prior to energization and verify that levels
are acceptable 500,000 ohms.
29.0 For adequate operation, always maintain the circulation
heater with the minimum design flow conditions for which the heater
was designed.
30.0 Retorque all bolted fitting connections and all electrical
connections after 10 cycles.
31.0 Always maintain a minimum of 51 mm (2”) of liquid above
the heated portion of the element or element failure may result.
MAINTENANCE
Disconnect all power before installing or
servicing the heater. Failure to do so could result
in personal injury and/or property damage. All
maintenance and installation should be done by
qualified personnel in compliance with local
codes.
32.0 Heaters stored for prolonged periods may absorb moisture.
Using a 500VDC megger (insulation resistance tester) check the
value of the insulation resistance to ground for each circuit. Initial
readings of over 500,000 ohms to ground are normally acceptable.
Should lower readings be observed, check factory for instructions.
33.0 Periodically check electrical connections for tightness and
check wire insulation for any damage and replace if necessary.
34.0 Remove the immersion heater periodically to inspect for
corrosion, sludge build-up and for scale removal. Discontinue use
if the heater shows signs of damage.
Note, the orientation of the flange or pipe plug relative to the vessel
before removal. Use a reference mark on the immersion heater
and vessel or draw a quick sketch showing the conduit connection
orientation, to ensure the proper orientation when re-installing.
35.0 Periodically check for leaks and torque of all bolted
connections.
Overtemperature devices in the heating bundles
are specifically located based on process and
heater design. Rotation of the bundles should
be avoided without consulting the manufacturer.
36.0 If a heater element is damaged (sheath rupture or electrical),
user must consult factory for further advice.
37.0 Heater output can be verified by loop current draw or
resistance check. If heater is not operating properly, user must
verify resistance, IR resistance to check integrity of heater elements.
38.0 All returning product to the factory must be totally clean
and a copy of the MSDS of the process fluid/gas must accompany
the product.
