C. Internal electrical connections consist of buss bars and jumper straps of either Mn-Ni or Monel.

D.Field wiring terminals of heavy duty 3/8” diameter bolts of either brass (iron sheath units) or stainless steel (chrome steel sheath units) with hardware are provided for field wiring connections.

2.Maximum temperatures — Type CAB and CABB air duct heaters can generally be used at the following maximum tem- peratures provided the minimum air velocity is maintained uniformly through the heater. Table 2 is based on the standard unit of 26 watts per square inch. If unit watt density is lower, higher temperatures can be achieved. If higher watt densities are used, outlet air temperature should be lowered.

3.Several heaters may be mounted in tandem as long as proper controls are used to limit the maximum temperature attained. See pressure drop curve G112S1 for effect of mounting in tandem.

4.Overtemperature protection — A thermal cutout should be installed at the exhaust side of the heater for protection against low airflow conditions.

INSTALLATION

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

1.Install heater into desired location in air duct with terminals on bottom.

2.For installation where the duct heater is larger than the duct- work, the duct area must be increased by a sheet metal transi- tion. The slope of the transition piece on the upstream side is limited to 30˚ as indicated in Figure 2. On the leaving side, the slope should not be more than 45˚.

3.Make sure ductwork is of sufficient strength to contain the heater. Refer to Table 1 for heater weights. Consult your local sheet metal contractor if in doubt.

4.Two holes 5/16-18 tapped are located on each side of the heater for mounting.

5.Air velocity must be sufficient enough to prevent element fail- ure. See Table 2 for guidelines.

6.For protection against accidental air stoppage, mount a ther- mal cutout on the exhaust side of the heater.

7.Insert thermal cutout sensitive bulb through duct and attach to heater case with mounting clips provided.

8.DANGER: Hazard of Fire. Since these heaters are capa- ble of developing high temperatures, extreme care should be taken to:

a.Avoid installing heaters in an atmosphere containing com- bustible gases and vapors.

b.Avoid contact between heater and combustible material.

c.Keep combustible material far enough away to be free of the effects of high temperatures.
