drive current to the pem cell thus reducing the generation of ozone at the pem cell in this manner the concentration of ozone vented into the atmosphere though the air outlet 76 may be limited to a safe level when the heat pump 100 is activated by the controller 220 the condensing element 14 is cooled to a temperature at or below the dew point of the incoming air stream 10 as indicated by the temperature sensor 71 water vapor in the air stream 10 condenses onto the condensing element 14 and drips into the collector 63 the collector 63 directs the water vapor condensate into the first reservoir 64 and the condensate accumulates in the first reservoir until the level of the water activates the first float switch 166 the controller 220 shown in fig5 receives the signal from the first float switch 166 at the inlet 224 and produces an activation signal at the output 230 to activate the pump 121 and cause condensate to be pumped from the first reservoir 64 through the condensate conditioner 66 and into the second reservoir 68 the condensate conditioner 66 filters the condensate to remove various contaminants as described above and also may re mineralize the condensate to improve the taste of the water supplied by the apparatus 60 the condensate is accumulated in the second reservoir 68 until the level of the condensate in the reservoir activates the second float switch 168 such that the controller 220 shown in fig5 receives a signal at the input 226 indicating that the condensate level in the second reservoir has reached the level of the second float switch 168 in response the controller produces a signal at the output 234 to deactivate the fan and a signal at the.
