OPERATION

1)
Insert the appropriate metering tips into the chemical feed lines (see illustration, page 5).
2)
Fill the holding tank with warm water (not exceeding 120 °F). Do not add any chemical to
the tank.
3)
Prepare the area for cleaning by emptying waste receptacles, clearing debris, removing
paper products, blowing out vents, and sweeping floors.
4)
Connect the 25 ft power cord to the pig-tail on the rear of the machine. Test the GFCI on
the power cord before each use. Plug the GFCI protected power cord into an outlet.
5)
PRIME THE PUMP: Attach the priming hose to the outlet quick disconnect and place the
open end of the hose into the recovery tank. Turn on the pump and let it run until the
pump is completely primed (no visible air in the water stream). Turn the pump off.
NOTE: prime the machine before you place the chemical feed tubes into chemical
containers.
6)
Disconnect the priming hose and attach the solution hose to the quick disconnect.
7)
Attach the spray gun to the other end of the solution line.
8)
Place chemicals in the molded-in chemical bottle containers on the rear of the machine.
Insert one of the feed lines into one of the chemical containers. Secure the line by
screwing on the cap. The chemical will feed from which ever container the selector valve
on the switch plate is turned towards and when the gun is used in the low pressure
setting. Use chemicals with a pH of between 4 and 12. Never add chemicals to the clean
water tank.
9)
Set the spray gun to low pressure by sliding the pressure selector forward (low pressure
= forward; high pressure = back).
10) Turn on the pump switch (push button) and spray through the gun for a few seconds to fill
the line with solution.
11) Apply the chemical to the walls and fixtures from the bottom up. Spray the floor last as
you work your way out of the room.
12) Allow the chemical to work for the proper amount of dwell time, according to the chemical
manufacturer's directions. Agitate heavily soiled areas with a scrub brush.
13) Turn off the chemical injector valve by turning the selector to the down position.
14) Set the spray gun to high pressure and rinse the area from the top down.
15) Connect the vacuum hose, attach the squeegee, and turn on the vacuum (rocker switch).
16) Squeegee off the mirrors, pick up the liquid off the floor with the floor tool. If you have the
optional blow dry hose, use it to dry the fixtures.
17) Drain the recovered water into a utility sink or toilet. NOTE: Keep the top of the drain
hose higher than the water level in the tank to avoid uncontrolled discharge of water
when you open the cap on the hose.
CAUTION
To avoid vacuum motor damage, always use a defoamer any time foam is present.
Before you turn on the vacuum always make sure the filter screen on the ball float is clean and
that the ball can travel freely.
RE-PRIMING THE PUMP
If the pump looses prime between jobs, follow the instructions to PRIME THE PUMP, above. If
that doesn't get water flowing, put the priming hose into the vacuum inlet hose barb and cover
the rest of the space around the priming hose with your hand. Turn on the vacuum (with the
pump also running) and let the suction of the vacuum assist in getting water into the pump.
