1. (0,1) - 0 = no service disconnect OR 1 = with service disconnect
2. (1,2) - 1 = with service disconnect, no breaker jumper bar OR 2 = with service disconnect and breaker jumper bar
3. 6HK3 = 3-phase with terminal block connectors only. 6HK4 = 3-phase with service disconnect
4. For ME14D and ME16C models with a 15 kW (6HK*65015**) heat kit, tie the AHU W1 and W2 thermostat inputs together for FER compliance.
TABLE 6: KW and MBH Conversions - For Total Power Input Requirement
For a power distribution voltage that is different than the provided nominal voltage, multiply the kW and MBH data from the table by the conversion
factor in the following table.
