Clean In-Line Pump Filter
CAUTION: before proceeding with this procedure, make
sure both the power cords are disconnected.
• Unlatch the base of the machine and tip the tanks back.
• Carefully expose the in-line filter in the motor base.
Unscrew the clear H20 cup.
• Remove the screen from the cup. Be careful not to bend
the screen.
• Rinse both the screen and cup with fresh water.
• Reassemble the H20 filter and replace it carefully into the motor base.
• Lift the tanks back onto the base and restore the latch.
IMPORTANT: this filter must be cleaned at least once a week to prevent water blockage
to the pump.
7.12
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.
