HEATER OPERATION
The disconnect fittings on the
heater will become extremely
hot during operation. Allow sufficient time to
cool, or run solution through the machine with
the heater turned off before disconnecting the or
performing any maintenance on the heater.
Before disconnecting the heater, open wand valve to
relieve the system of all pressure by depressing the
valve trigger.
DO NOT spray water directly on to the heater. To
clean, unplug the unit and wipe with a damp cloth.
Make certain that the solution
tank is filled adequately before
plugging in the machine and heater.
1. Plug the machine and heater into separate
grounded circuits. The heater draws 15 amps of
current.
2. Turn the solution pump ON. Turn the heater
switch ON. The solution pump must be turned on
BEFORE the heater is turned on.
The heater requires about 5-6 minutes to reach
operating temperature, approximately 250°F.
When turning the machine and heater OFF, make
certain that you turn the heater off FIRST.
EMPTYING AND CLEANING
Always use defoamer if
foaming occurs. Foam will
suspend large particles that may damage
vacuum(s) as well as allow liquid into the vacuum
motor(s) without activating the float shutoff.
1. Before proceeding, make certain that the nozzle
is functioning properly.
a. To check, hold the wand about one foot
above the surface to be cleaned and open
the wand valve. A full spray should be
observed from the nozzle.
b. If the nozzle is not showing a full spray
pattern, adjust nozzle for proper pattern,
clean, or replace nozzle.
2. Normally, chemical is applied on the push stroke
while vacuuming is done on the pull stroke.
For heavily soiled carpets the hand tool may
be used in the scrubbing manner, applying
chemical in both the push and pull stroke.
ALWAYS FINISH UP AN AREA WITH A VACUUM PULL
STROKE.
3. When cleaning, keep the working opening (wand
mouth) flat on the surface being cleaned. Keep
the wand moving when the valve is open.
4. The shutoff float inside the recovery tank will
impede the vacuum flow when the tank is full.
When this occurs, empty the recovery tank. Do
this by opening the dump valve located at the
back of the machine. NOTE: Dispose of waste in
a proper manner which would not violate any
Local, State or Federal law.
5. Once the recovery tank has been emptied, you
may once again proceed with cleaning.
Operating Vacuum after shutoff
has activated could draw water
directly into the vac motor. This will cause
damage to the motor, therefore voiding your
warranty.
Always test carpet for color
fastness in an inconspicuous
place. Also, to avoid prolonged drying times, do
not spray too much solution in any one area.
SHUT DOWN AND STORAGE
1. Turn Switch OFF. Empty recovery tank
completely and rinse several times to remove
any dirt or debris that may be left behind.
2. Drain any unused cleaning solution from solution
tank and rinse with clean water to remove any
suds left behind by the cleaning chemicals.
NOTE: Dispose of waste in a proper manner
which would not violate any Local, State or
Federal law
3. Run a small amount of clean water through pump
if chemicals were used. This will help insure the
life of your pump.
4. Check the spray jet on the cleaning tool for full
spray pattern and inspect vac head for any
obstructions.
5. Remove as much moisture from system before
storing in cold climates. Excess water may freeze
during storage and crack internal components,
causing damage to the unit.
Before making any
adjustments or performing any
maintenance to your machine, disconnect the
power cord from the electrical source.
