»See condensing unit or heat pump outdoor section PDS for cooiing and/or heating capaoity ratings with 517G Fan Coils.
fSee air delivery table in this PDS.
tKW values shown are nominal rated heater outputs at 240V and do not include blower motor heat. Capacity values shown are calculated using KW
outputs at 208V/230V.
»»Single-phase 10-, 15-, or 20-KW electric heaters have the internal circuit protection options shown. Single-phase 12-, 15-, or 20-KW heaters are
wired for dual-oirouit operation. The optional single-circuit kit may be field-installed in units with a 12-, 15-, or 20-KW single-phase fused heater for
single-circuit operation.
ttCB = circuit breakers.
ttUsed for right-angle refrigerant connections to the coil.
»»»Wire sizes and lengths are based on copper conductor at 86 ° F (30 ° C) ambient temperature and ampacity shown in table. Insulation must be 90 ° C
on conductor used between the disconnect switch and the heater and at least 75 “ C on the conductor used between the disconnect and the serv
ice panel. If other than copper oonductor is used, or is ambient temperature is above 86 °F, determine wire size from ampacity shown and the Na
tional Electrical Code. Wire lengths shown are measured one way along the wire path between the disoonnect and service panel for minimum 2%
voltage drop.
