6.11 Flush Chemical System
Chemical build-up in the chemical system can prevent the system from drawing
chemical.
• Rinse the chemical system with fresh water (for heavy chemical build-up, a mild acid
can be added to the rinse water).
• Remove the chemical feed hose from the solution tank and place the end of the
chemical feed hose into water or mild acid solution.
• Connect the auto-fill water supply hose to the water inlet (male quick disconnect) on
the front of the machine.
• Connect the other end of the hose to a water faucet and turn ON the water. Let the
water flow into the tank until you are sure the rinse solution has been drawn through
the proportioner and mixed with the incoming water. The metering tip can be removed
from the proportioner to speed up the process.
• Once the rinse solution has been drawn through the proportioner, turn OFF the water
faucet and disconnect the auto-fill water supply hose.
• Plug in Cord 1 (left side), connect the short 4-foot vacuum hose to the vacuum barb,
turn on one or both vacuums and use the short vacuum hose to remove the water from
the solution tank.
• When the solution tank has been emptied, turn OFF the vacuums and unplug the
power cord.
• Place a bucket under the dump valve and open the dump valve to drain the water from
the recovery tank.
• Close the dump valve and dispose of the water.
