OPERATION
1
Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2
Fill the solution tank with warm water. Using warm water may be a benefit in cleaning
effectiveness, but do not use hot water (above 140
°
F / 60
°
C) in the tank. Add liquid cleaning
solution with a pH of between 6 and 9.
3
Plug in the power cords. Do not connect both cords to the same outlet; the circuit locator
light on the switch plate should light up. If the locator light does not come on, try different
outlets until it does. If you are certain the cords are on separate circuits, turn the heat
switch on.
CAUTION:
using the heat switch when the cords are on the same circuit may
cause the breaker to trip.
NOTE:
the cord with the red sleeve powers the heat exchanger.
4
Attach the spray hose to the solution quick disconnect and the vacuum hose to the hose
barb on the recovery tank. Attach the other ends of the hoses to the cleaning tool.
5
Turn the pump on and spray from the tool to make sure everything is working, and to fill the
heat exchanger with water.
NOTE
: the pump has a built in pressure switch; the pump only
runs when you are spraying.
6
Allow the heat exchanger two minutes to reach operating temperature.
7
Turn the pump on. Turn the vacuums on.
8
Begin cleaning using the correct hoses and tool.
9
Use defoamer in the recovery tank any time foaming occurs.
10
Monitor water level in the solution tank. Do not let the pump run dry.
11
When the solution tank gets low, turn off the pump, fill the solution tank, empty and clean the
recovery tank.
12
When finished with the job, remove any unused solution from the solution tank, and run a
few gallons of clean water through the system.
BALL FLOAT VACUUM SHUT-OFF
Prior to using the machine, always check that the float filter is clean and the ball can travel freely.
When the recovery tank is full, the ball float will rise and will shut off the vacuum flow to prevent
any more water from entering the tank. Turn off the vacuum, and empty the recovery tank.
NOTE: if foam is present, or if the ball float is prevented from rising, the float will not be able to
stop the air flow, and the tank may over fill.
CAUTION!
To avoid vacuum motor damage, always make sure the float filter is clean and the ball can travel
freely prior to using the machine. And always use a defoamer when foaming occurs.
ELECTRIC CIRCUIT LOCATOR
This unique, patented system is operated by a solid state circuit. It will inform the operator when
the two cords are plugged into separate circuits by turning the circuit locator light
(1)
on
.
This
helps to prevent tripping circuit breakers.
NOTE
: if the circuit locator light does not illuminate when the cords are plugged in, then both
cords are on the same circuit. Try other outlets with one of the cords until you get the locator light
to come on.
CAUTION:
if the Heat switch (
2
) is turned on when both cords are on the same circuit, the
breaker will trip.
