Heater Pack Replacement
The heater pack series is determined by the 6th character of
the Catalog Number. Series A or prior heater packs (identi-
fied by either “A” or “-” as the 6th character) have built-in
load lugs. Series B or later heater packs do not (load lugs are
on overload relay). Replacement of Series A or earlier heater
packs with Series B or later heater packs, requires the one
time addition of Lug Adapter Kit C3606KAL1-3B to the Series
A1 overload relay.
