    SECTION THREE: OPERATION SECTION THREE: OPERATION UNDERSTANDING THE SYSTEMS NOTE: Read and understand this section of the manual entirely before proceeding. This portion of the manual divides the unit up into systems and describes how each system works. Prior to proceeding into the operations and maintenance sections of this manual it is recommended that you acquire a basic understanding of how the unit functions.
  • Page 29 SECTION THREE: OPERATION WATER HEATING SYSTEM The water reservoir is a pressurized vessel. Cold water enters the console through the water inlet connection located on the lower left corner of the lower front panel. The water then flows through the Inlet Pressure Regulator (where incoming water pressure is reduced to 18-20 psi) and into the water box.
  • Page 30 SECTION THREE: OPERATION VACUUM SYSTEM The engine turning a vacuum pump generates the vacuum. The air is channeled in one side of the vacuum pump, compressed and discharged on the opposite side, creating airflow. This airflow is used to do the work necessary for the extraction process.
  • Page 31 SECTION THREE: OPERATION CHEMICAL PUMPING SYSTEM The chemicals are drawn from the chemical container through a strainer into the flow meter mounted on the control panel. The flow meter indicates the rate of chemical flow. The chemicals then flow through the stainless steel chemical pump, the chemical is then injected into a three way selector valve located on the front panel.
