WIRING

WARNING: Hazard of Shock. Any installation involving electric heaters must be effectively grounded in accordance with the National Electrical Code to elim- inate shock hazard.

1.Electrical wiring to heater must be installed in accordance with the National Electrical Code and local electrical codes by a qualified person as defined in the NEC.

2.Because of the high operating temperatures expected, aluminum wiring is not recommended.

3.Refer to wiring Diagram Figure C for typical wiring used for con- necting the NWHO-27 series heater.

4.Three 3 phase circuits is a typical design for these heaters. Other circuit arrangements are often supplied depending upon customer specifications or amperage rating. Check engineering drawing for specific wiring diagram of custom orders.

OPERATION

1.Do not heat materials that are corrosive to the heating element sheath or chamber. For oil heating service, condensate drain may be provided from bottom of chamber. Check factory.

2.Terminal ends of heater must be protected from drippings conden- sation, spray or direct spill-over of material whose presence at the

terminals may damage heater’s electrical insulation. Liquid-tight terminal enclosures are available to protect heater. Check factory.

3.If foreign material is carried by the oil flow, install suitable filters in the inlet pipe to the heater.

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

MAINTENANCE

WARNING: Hazard of Shock. Disconnect all power before servicing heater.

1.Remove heating element assembly periodically to check heater sheath for corrosion or excessive oxidation. Correct operating con- ditions to minimize sheath deterioration.

2.Periodically check temperature control and pressure temperature

safety 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 terminals which show signs of oxidation which would interfere with estab- lishment of reliable electrical connections.
