CX & DX Series

Special Notes

ELECTRIC SHOCK HAZARD. All electric heating equipment installations must be performed

by qualied personnel in accordance with the local electrical codes and standards and must be

effectively grounded to eliminate shock hazard.

WARNING

FIRE/EXPLOSION HAZARD FOR HAZARDOUS LOCATION HEATERS. Thisheater shall

be used with protection controls as follows:

Liquid Immersion Applications

a. Liquid level control to maintain all the heating elements totally immersed at all times, in

conjunction with temperature controls to limit the liquid temperature below the maximum

allowable process design temperature, or

b. Heating elements sheath temperature controls to limit to the maximum allowable sheath

design temperature

WARNING

FIRE/EXPLOSION HAZARD. Do not exceed the ratings of the ange as listed in ANSI BI6.5.

In case of code stamped of registered heater, do not exceed the rating as stated in the data

report and/or registration documents. Do not operate the heater in the presence of combustible

gases, vapours, dusts or bres unless the heater is specically marked for the hazardous

location and heater operating temperature does not exceed the temperature code rating.

Corrosion of the sheath could result in a ground fault which, depending upon the uid being

heated, could cause a re or an explosion.

WARNING

FIRE HAZARD. If a thermostat is provided, it is designed for temperature control service only.

Since the thermostat does not fail safe, it should not be used for temperature limiting duty.

Wiring to this device is the users' responsibility.

Heaters are capable of developing high temperatures, therefore extreme care should be

takento:

a. Use explosion-proof terminal enclosures in hazardous locations;

b. Maintain distance between heater and combustible materials.

CAUTION

CAUTION. This document presents the minimum requirement pertaining to the

installation, operation, and maintenance of the respective equipment as required by the

manufacturer only. Any additional considerations, including but not limited to any design

consideration, in-service inspection, and tness-for-service assessment for all pressure

boundary components to meet any safety principles and local jurisdictional regulatory

requirements, shall be the responsibility of the user.

B. 1. DESCRIPTION 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 2. CAUTION Use the heater only in liquids and at pressures for which it was designed (unless specifically 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.

. Insert heater into vessel/reservoir and verify that the heating elements are not making contact with the surface of the vessel. 5. Check that all terminal connections are tight. CAUTION CAUTION Use copper conductors only with sufficient current carrying capacity for the heater circuit load and in accordance with the local electrical code. Check the heater nameplate for minimum conductor temperature rating. Temperature deration factors must be applied for heaters operating above 30°C (86°F). 6.

E. MAINTENANCE WARNING Disconnect all power before servicing WARNING the heater or heated equipment. 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. 1. Heaters stored for prolonged periods may absorb moisture. Using a 500V DC megger (insulation resistance tester) check the value of the insulation resistance to ground for each circuit.
