NOTES:
1. All heaters are single stage and single-phase. Two-stage heaters
may be available with a special request.
2. In all units using over 48 amps, the heating elements are subdi-
vided and protected. Additional cost is incurred because of added
components. Each circuit of the electric heater coil has an auto-
matic reset thermal cutout with back-up high limit control and oper-
ating contactor.
