CCI Thermal Technologies HX - Straight Unfinned Tubular Heater (Calrod type*) - Manuel

ISO 9001
MI169 REV.7.01
INSTALLATION AND MAINTENANCE INSTRUCTIONS
TUBULAR HEATERS - TYPES HX & IX
1.0 APPLICATION
1.1 Tubular elements of proper rating, material and shape can be applied to most heating applications requiring process
temperatures to 1382°F (750°C).
1.2 Tubular elements may be clamped, immersed, cast into metal or spaced away from the work as radiant heaters. Elements can
also be positioned in ducts or vessels for heating air or other gases.
1.3 Check factory for recommendations if you are unsure of the suitability of the HX or IX heater to your application.
2.0 INSTALLATION
2.1 The terminals must be protected at all times from moisture or vapour. In hazardous locations, explosion resistant terminal
housings must be used. In outdoor locations, moisture resistant housings are required.
2.2 Protect terminals of heating elements from drippings, condensation, fumes, spray or any other substance which could result
in element contamination.
2.3 When melting solids by direct immersion, a surface vent should be provided to allow gases to escape. Operate the heater at
½ voltage until melted material completely covers the heating elements. Heaters used for this purpose may require special design
features. Check factory for recommendations.
3.0 WIRING AND CONTROL
3.1 Heaters must be wired by qualified personnel to electrical code requirements.
3.2 Check supply voltage for compliance with heater nameplate voltage.
3.3 A line voltage or pilot duty thermostat should be used to control the heater. The pilot duty thermostat must be used with a
contactor and (if required) a transformer. Generally, heaters supplied with built-in thermostats will be factory prewired if suitable for
line voltage operation. Integral thermostats not factory prewired are usually intended for pilot duty.
3.4 Heaters with explosion resistant terminal housings must only be used in locations for which the heaters are certified.
a) Check heater nameplate information for approval code.
b) Never energize an explosion resistant heater unless the terminal housing cover is properly tightened.
4.0 START-UP INSPECTION
4.1 Check that all terminal connections are tight.
4.2 Heaters stored for prolonged periods may absorb moisture. Using a 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.
5.0 MAINTENANCE
5.1 DISCONNECT POWER BEFORE SERVICING.
5.2 Inspect periodically for corrosion, sludge build-up and for scale removal.
5.3 Periodically check electrical connections for tightness.
