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 fl oors.
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 fi ll
the line with solution.
11) Apply the chemical to the walls and fi xtures from the bottom up. Spray the fl oor 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 fl oor with the fl oor tool. If you have the
optional blow dry hose, use it to dry the fi xtures.
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 fi lter screen on the ball fl oat 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 fl owing, 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.
