WIRING

CAUTION: Hazard of Electric Shock. Any installa- tion involving electric heaters must be grounded to earth to eliminate shock hazard.

1.Electric wiring to heater must be installed in accordance with National Electrical Code and with local codes.

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

3.Refer to Wiring Diagram Figure B for the typical wiring used for connecting the NWHO-45 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.

OPERATION

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

WARNING: Type NWHO Circulation Heaters are equipped with steel heating elements and galva- nized-steel heating chambers. It is the responsibil- ity of the user to know the chemical composition of the corrosive solution and the character of the materials entering the solution as well as the cor- rosive effect of the solution upon the heating ele- ments and chamber. Chromalox cannot warrant any electric circulation heater against failure by

sheath corrosion if such failure is the result of operating conditions beyond our control.

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

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

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