Chromalox Type RAD Radiant Heaters

Converting Styles 0, 1, 3 and 3A to 3B

GENERAL

The current Chromalox Style 3B RAD has superseded earlier Styles 0, 1, 3 and 3A RAD heaters. These instructions are for con- verting these earlier models to the current Style 3B. This conversion is necessary because replacement parts for the old models are no longer available.

The changes involved are primarily in the terminal area as shown in Figures I, 2 and 3. Match-up one of the Figures with your

heater's terminal arrangement and order the corresponding parts bag (Figures 4 and 5). If an element or other part listed in Table A (page

3)is necessary, order according to heater housing length and the voltage and wattage stamped on the element and the heater name- plate.

For complete installation information for type RAD - Style 3B, request Chromalox Service Reference sheet PG404.

CONVERSION

CAUTION: Hazard of electric shock. Disconnect power before servicing heater.

A.CONVERTING STYLES 0 AND 1 TO STYLE 3B RADIANT HEATER

1.Completely disassemble heater. Re-use the heating element (if desired) and the extruded aluminum housing (Fig. 7). Scrap all the other parts.

2.Drill #24 (.152" dia.) hole in the back of the extruded housing A , 3" from each end. (See Fig. 7)

3.NOTE: If replacing old element with a new one, omit this step. Remove wire retaining loops B (Fig. 6) from the elements and replace with wire loops fashioned from #15 gage (.072" dia.) or larger stainless steel wire located 2-1/4” from each end of the sheath. Other high temperature materials such as nichrome may be substituted. Braze or tack weld the loops in position.

4.Besides the Parts Bag 168-016585-002 (Fig. 4), you will need

insulation bushings 6 element support clips 7 , reflector 2 and element (if required) as listed in Table A, page 2.

NOTE: Quantities of these parts, as well as size of element and reflector will be determined by the heater housing length of the old unit.

5. Assemble heater as shown in Figure 7.
