Pre-heating water You may pre-heat the water in the solution tank by letting the warm water coming from the heater flow going into the solution tank of the machine. After recirculation, the water in the solution tank becomes warm. This way, you may obtain water at a higher temperature at the outlet of the heater. In order to perform the recirculation, do the following: 1. Unscrew the male quick disconnect from the center of the heater, and insert it into the female quick disconnect fitting at the accessory end of the solution hose. (This step is necessary as the female fitting at the end of the hose has a check valve inside of it). 2. Insert the end of the solution hose into the solution tank of the machine. 3. Switch the water pump and the heater on. This will pre-heat the water and discharge it back into the solution tank. 4. Let the water re-circulate in the solution tank. After 10 minutes you can have 6.6 gallons of water increasing in temperature by 10 °C (50°F). Example: If the water in your solution tank is 50°F and you re-circulate the water for 10 minutes before use, the water in your solution tank will be approximately 100°F. 7
