Description
B. DESCRIPTION
1. Immersion heaters for liquid service are designed for operation
only while completely immersed in liquids. Never allow the
heating elements to be exposed while energized or failure will
result.
CAUTION
CAUTION Use the heater only in liquids
and at pressures for which it was designed
(unless specically designed for non-liquid
applications). Normally copper sheath is
recommended in water, steel or alloy sheath
in oil, and the appropriate alloy sheath for
heating chemical solutions. Check factory for
recommendations.
2. In the case of flanged (and some screwplug type) heaters
where a gasket seal is required, the gasket surface should be
clean and dry before the heater is seated.
WARNING
WARNING DO NOT insulate over the heater
ange, stilted area and terminal enclosure.
3. The terminals must be protected at all times from moisture
or vapour. In explosive atmospheres, explosion resistant
terminal housings must be used. In outdoor locations,
moisture resistant housings are required. It is recommended
to use a drip loop to prevent moisture from entering the
terminal box via the wire or cable.
4. Protect terminals of heating elements from drippings,
condensation, fumes, spray or any other substance which
could result in element contamination.
5. When melting solids by direct immersion, a surface vent
should be provided to allow gases to escape. Operate the
heater on ½ voltage until melted material completely
covers the heating elements. Heaters used for this purpose
may require special design features. Check factory for
recommendations.
