† These models can be field changed from single phase to three phase or three phase to single phase. © 2010 Chromalox, Inc. IMPORTANT Failure to understand and follow these installation instructions and the “WARNING” notes therein may result in serious personal injury from electrical shock, or from the heater failing due to faulty installation. FIRE/EXPLOSION HAZARD. This heater is not intended for use in hazardous atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are present as defined in the National Electrical Code. Failure to comply can result in personal injury, explosion or fire. For these applications see PDS CXHA- EP (PF490). Users should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequenses of failure may be severe, back-up controls are essential. Do not mount mercury type thermostat directly on unit. Vibration could cause heater to malfunction. The heater must be mounted at least 7' above the floor to prevent accidental contact with the heating elements or fan blade which could cause injury. Keep at least 5' clearance in front of the heater. Refer to Table 2 for side, top and back clearance requirements. The ceiling mounting structure and the anchoring provisions must be of sufficient strength to support the combined weight of the heater and mounting bracket. (Refer to Table 3 for weights of heater and bracket.) The wall or mounting surface, and the anchoring provisions must be capable of supporting the combined weight of the heater and mounting brackets cantilevered from the mounting surface. (Refer to Table 3 for weights of heater and brackets and for cantilevered force expressed in foot-pounds.) Fan blade rotation must be checked. If airflow is not moving out through the louvers, interchange any two of the three customer power leads on three-phase units only.

Locate thermostat on interior partition walls or posts away from cold drafts, internal heat sources and away from heater discharge air streams. Small rooms can be heated by one unit heater. Where two walls are exposed, the heater should be mounted as shown in Figure 1. Figure 1 ExposedExposedExposedExposedExposedExposed INSTALLATION Please read all of the following instructions: Failure to observe these precautions could result in personal injury or equipment damage. 1. The heater must be mounted at least 7’ above the floor to prevent accidental contact with the heating elements or fan blade which could cause injury. 2. Keep at least 5’ clearance in front of heater. Refer to Table 2 for side, top and back clearance requirements. Clearance Requirements — Table 2 Basic Model Mounting Limitations (In.)

The ceiling mounting structure and the anchoring provisions must be sufficient to support the combined weight of the heater and mounting bracket. (Refer to Table 3 for weights of heater and bracket.) 4. The wall or mounting surface and the anchoring provisions must be capable of supporting the combined weight of the heater and mounting brackets cantilevered from the mounting surface. (Refer to Table 3 for weights of heater and brackets and for cantilevered force expressed in foot-pounds.) The heater may be mounted either on the ceiling or on the wall as follows: A. CEILING. The ceiling mounting bracket is fastened to the top of the heater using the four bolts supplied with the mounting bracket. The bracket is then mounted to the ceiling using a 5/8” bolt (supplied by others). CEILING (Alternate) 1. The heater can be rod mounted to the ceiling by installing four threaded mounting rods in the threaded holes located on the top of the heater as shown in Figure 2. (Refer to Table 4 for mounting rod thread size.) 2. Securely attach the four mounting rods to the ceiling. (Refer to Table 2 for wall and ceiling clearances, and Figure 3 for mounting spacing specifications). B. WALL. Wall mounting kits include both a ceiling mounting bracket and a wall mounting bracket. First, attach the ceiling mounting bracket to the heater as described in step 4A. Then attach the wall mounting bracket to the wall using four 3/8” bolts (supplied by others). Attach the ceiling mounting bra...
