 Type 6 - Theory of operation and equipment part numbers.

Espree ll (after 11/88), Z-10A, Delfino, and the Alexa all use a F570000  (1 Pump 2-speed) Non-SCM system much like the Type 2 system. This newer 0073000 (0074) DC Coil version (small blue box), utilizes a 5260000 Four-Function Air Switch to control the Whirlpool, Heater/Filter and Filter Modes. The 115 VAC supply voltage is converted by (2) 8747000 Bridge Rectifiers to DC Voltage for operation of the (3) 8745000 110 VDC Coil Relays*. This non-convertible 115 VAC system utilizes a 5251000 1.5 kW heater assembly with M490000 Hi-Limit and adjustable (N/A) Thermostat. B754000 Flow Switch is used to prevent the power to the heater if water is not circulating.
