FLA — Full Load Amps
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.
3. Electric heater and motor voltage must be the same and need to
be ordered in conjunction with a single power source wiring option.
This option, which meets NEC (National Electric Code) require-
ments, consists of a factory-furnished and installed junction box
and fuse for 6.25 amp (max) fan and control circuit connection to a
single power source. All units with electric heat must include a
fused service switch. Power supply circuit to unit must be field fur-
nished and installed in accordance with applicable codes.
4. Fan coil units comply with ETL, Canadian Standards Association
(CSA), and ETL of Canada standards.
