GENERAL The Chromalox FXTH Flexible Tank Heater is designed for heating viscous liquids in large steel, concrete or fibrous glass tanks with normal manhole entry. Standard equipment with every heater includes flexible pipe and 14’ riser(s), two lifting cables, 4” high sludge legs and a 50-250° non-indicating thermostat with well, overtemperature probe and weatherproof terminal housing. The Control Center OCC (NEMA XII, oil and dust-tight construction) or WCC (NEMA IV, weather-resistant construction) is designed for controlling the temperature of the viscous liquids by regulating the FXTH's on-off cycle. It is mounted remotely with standard components consisting of a NEMA XII or NEMA IV enclosure with vertical wall mounted brackets and hasp and staple for padlocking. Electrical components include: Failsafe overheat device, master circuit- breaker, contactor(s), relay(s), selector switch, pilot lights, fuses and a 120-volt control circuit transformer. IMPORTANT-Before attempting to uncrate or install the FXTH heater, read and understand all of the following instructions. Proper handling is absolutely necessary to obtain satisfactory operation. All electrical connections are to be made by a qualified electrician. To avoid excessive separation, stratification, sludge formation, etc., in your FXTH heated storage tank, consult a qualified oil supplier regarding selection and blending of fuel oils. UNCRATING AND HANDLING OF HEATER NOTE: Inspect shipping crates before opening. Contact the carrier if damage is evident. 1. Check to see that all components are included. FXTH immersion heaters are shipped as subassemblies consisting of (a) flexible heater with riser tubes, (b) terminal housing, (c) thermowells and vent tube, and (d) control unit (if ordered). 2. To unpack flexible heater, keep crate in upright and horizontal position when removing heater. Only top boards of crate need to be removed. 3. When lifting heater assembly, do not bend heater to radius less than 22". Heaters should be flexed in vertical plane only. This is a plane perpendicular to the sludge leg base plates. Bending in horizontal plane can damage internal ceramic insulators. 4. Use several people to lift heater - the number depends on the length and weight of...
