OPERATION

FIRE/EXPLOSION HAZARD. Do not exceed the Pressure-Temperature rating of the flange as listed in ANSI B16.5.

IMPORTANT: It is the responsibility of the purchas- er of the heater to make the ultimate choice of sheath material based upon his knowledge of the chemical composition of the corrosive solution, character of the materials entering the solution, and controls which he maintains on the process.

Sheath corrosion can result in a ground fault which, depending upon the solution being heated, can cause an explosion or fire.

1.Do not heat solutions that are corrosive to the heating element sheath or the heating chamber.

2.Terminal ends of heater must be protected from drippings, con- densation, spray or direct spill-over of material. Their presence at the terminals may damage heater electrical insulation. Liquid-tight terminal enclosures are available to protect heater. Check with local sales office.

3.If foreign material is carried by the liquid flow, install suitable fil- ters in the inlet pipe line to the heater.

4.Do not allow heater to operate when liquid flow is interrupted.

MAINTENANCE

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property damage. Heater must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.

1.Remove heating element assembly periodically to check heater sheath for scaling, corrosion or excessive oxidation. Correct oper- ating conditions to minimize sheath deterioration.

2.Periodically check temperature control and limit control operation to insure accurate and safe process operation.

3.Check all electrical connections periodically and retighten connec- tions which may have loosened in service. Replace wire and wire terminals which show signs of oxidation which would interfere with establishment of reliable electrical connections.

Note: The “F” in NWHO(F) means forced circulation (ie: equipped with baffles.) When replacing the heating element, care must be taken that the baffles line up properly with the inlet and outlet pipes. The top of the flange of replacement heating elements for forced circulation heaters is stamped near one edge with the letter “P”. The sub-assembly is positioned correctly when the “P” on the flange is in line with the inlet and out- let pipe. Incorrect placement will result in hindered circulation and possible failure of the element.

Note: When ordering parts for Model Numbers suffixed by “XX” or any other letter or letters not specifically identified on this instruction sheet, order Renewal Parts on special order basis, giving name of part, part number and description.
