OPERATION

1.Do not heat solutions that are corrosive to the heating element sheath or the heating 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, condensation, spray or direct spill-over of material. Their presence at the terminals may damage heater electrical insula- tion. Liquid-tight terminal enclosures are available to protect heater. Contact your Local Chromalox Sales office.

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

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

MAINTENANCE

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

2.Remove heating element assembly periodically to check heater sheath for scaling, corrosion or excessive oxidation. Correct operating conditions to minimize sheath deterioration.

3.Periodically check temperature control and limit control oper- ation to insure accurate and safe process operations.

4.Check all electrical connections periodically and retighten connections 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.
