IMPORTANT

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

WARNING: 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 explosion or fire. For these applications see PDS CXH-EP (PF305).

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 installation is the responsibility of the user, Chromalox will be glad to make equipment recommendations.

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 Figures 1 and 2 for side, top and back clearance requirements.

The wall or ceiling mounting structure and the anchoring provision must be of sufficient strength to support the combined weight of the heater and mounting bracket. (Refer to Table A for weights of heater and bracket).

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.
