WIRING

WARNING: Hazard of Electric Shock. Any installation involving electric heaters must be effectively ground- ed in accordance with the National Electrical Code to eliminate shock hazard.

1.All wiring should be done in accordance with the National Electrical Code and with local codes by a qualified person.

2.Connect air heaters to same line voltage, phase and frequency as on heater nameplate.

3.Teflon insulated nickel plated copper wire or buss bar is rec- ommended for power connections to heater terminals and for

wiring runs in heated zones. When ambient temperature in heated zone exceeds that for which insulated wire is recom- mended use bare nickel-plated copper with porcelain beads, tubing or buss bar. Consult local Chromalox representative.

4.Users should install adequate back-up controls and safety devices with their electric heating equipment. Selection of controls, thermostat, SCR units, contactors and etc. depends on the degree of accuracy required, reliability, electrical rating of heater and economic considerations.

5.Below is an example of standard CAB 122 480V 3P 12 kW wired with recommended back-up controls (Figure 3).

OPERATION

WARNING: Users should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequences of failure may be severe, back-up controls are essen- tial. Although the safety of the installation is the responsibility of the user, Chromalox will be glad to assist in making equipment recommendations.

1.Do not operate heaters at voltages in excess of that stamped on the heater since excess voltage will shorten heater life.

MAINTENANCE

WARNING: Hazard of Severe Shock. Disconnect all 2. Check for loose terminal connections. power to heater before servicing or replacing heaters.

1.Periodically clean terminals and terminal covers of dust and corrosion to maintain good electrical connections and to per- mit rapid heat dissipation. Use airblast, and be careful to avoid damage to mica insulation.
