GENERAL

The Chromalox Type RBC-3 Radiant Heater is designed primar- ily as an indoor comfort heater to be used where supplemental heat is needed or for spot heating in unheated areas and damp locations.

Its aluminum construction and consequent light weight make it ideal for suspension with the No. 2 size chain and “S” hooks pro- vided. Aluminum reflector housing requires no painting and is eas- ily cleaned.

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

MOUNTING

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

Minimum mounting distances for all heaters are as shown in Figures A and B. Using the No. 2 size chain and “S” hooks fur- nished, heaters are to be suspended in a horizontal position only.

NOTE: For proper balance, it is suggested that each of the four corners be individually suspended (rather than gathered into a common center mounting point, see Figure C and D).
