where it returns back into the Circulating Tank.  Water flows through the leveling line from the 
Circulating Tank back into the Main Tank. During this cycle, the temperature of the water is 
controlled by activating the Heater or Mixing Pump. Automatic activation of the Bypass Valve 
occurs briefly at the beginning of both Automatic Mode and Manual Mode in order to completely 
prime the Circulating Pump.  If pads are connected, the Bypass Valve will close after one minute.   

A user can initiate the Purge Mode in order to empty the pads of water prior to disconnecting 
them.  Purge Mode causes the Vent Valve (VV) to open to atmosphere through the vent line 
communicating with the top of the Main Tank.  This causes air to be drawn into the pads and the 
circulating circuit, emptying the pads.   

The water level in the Main Tank is sensed by detecting conductivity with an array of stainless 
steel studs in the tank.  There are five level sensors and a reference sensor.
