2004 Caldera Spas Aspire Circulation Pump Blue, 1/50 hp, .58A, 115 VAC 60 Hz The circulation pump draws water through the circulation pump filter and then pushes it past the heater, bleedline, ozone (if equipped) injector and back into the spa through the heater return fitting. Its function is to circulate the water through the heater for the maintenance of temperature and to provide continuous filtration of the spa water. The circulation pump uses the water to cool the itself, it may feel hot to the touch. The pump is self lubricating, when operating the impeller rides on a thin layer of water between the ball and the bowl. These pumps should NOT be operated without water present in the spa. The spa should be pre-filled before the spa is connected to power as the pump automatically starts when the spa is operational. A dry run will trip the pumps internal temperature sensor shutting down the pump until the interanal temperature returns to normal.
