WARNING
IMPORTANT SAFETY INSTRUCTIONS
Read all instructions before using this vapor- steam cleaner.
1. Warning: Risk of injection or severe injury – keep clear of nozzle – do not direct
discharge steam at persons – this product is to be used only by trained operators.
2. Operate the machine only wearing appropriate PPE.
3. Do not use the equipment near anyone not wearing appropriate PPE.
4. Warning: Hot accessories can lead to injuries, do not touch with bare skin.
5. Make sure that the water you ll into the water tank is clean. Avoid the use of
buckets or canisters to ll the tank unless these are completely free of dirt or
foreign objects.
6. Do not drag the machine by pulling the hose, this can damage the hose.
7. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
8. Check the power supply cable before use for any damage. In the event of damage
to the power supply cable, have it immediately replaced by the manufacturer or
qualied personnel.
9. Warning: Extension cords are NOT recommended with this unit.
10. Never immerse any part of the machine in water or other liquids.
11. Check the steam hose and all accessories for damage before use and replace or
have them repaired immediately.

15. Never use the machine in a tilted position, all 4 wheels must stand on a
level surface.
16. Do not clean heat sensitive materials with steam, the heat of the steam could
cause damage.
17. Ventilate work area when using toxic or pungent additives to reduce your
exposure to toxic fumes.
18. Be careful of slippery oors. Some additives make a normally safe area extremely
slippery and dangerous.
19. Keep operation area clear of all persons. Do not use unit with children or visitors in
the immediate area.
20. Do not change nozzle size. An incorrect nozzle could cause excessive pressure
resulting in equipment damage and possible personal injury.

at all times.
25. Stay alert and watch what you’re doing.
26. Both front casters must be locked when unit is plugged into power supply.
GROUNDING INSTRUCTIONS
This vapor-steam cleaner must be grounded. If it should malfunction or break
down, grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped with a cord having an
equipment-grounding conductor. The cord must be wired into an appropriate
outlet that is properly installed and grounded in accordance with all local codes
and ordinances.
DANGER: Improper connection of the equipment-grounding conductor can result
in electric shock. Check with a qualied electrician or service person if you are in
doubt as to whether the outlet is properly grounded.

OPERATION
WARNING: Always wear gloves, protective glasses and ear protection while
operating this machine.
1. Turn the main power disconnect 8(Pic.1) to the ON position, Power ON LED
5.1 (Pic.2) will illuminate.
2. Open the water supply, and switch the Water Feed switch 4.2. to the ON
position. The tank will begin to ll; sensors ensure the correct water level. The
internal water tank is relled automatically and continuously.
CAUTION: Never switch ON the Water Feed Switch 4.2. (Pic.1) if the machine is
not connected to a water hose. This would cause water to ow out of the tank and
onto the oor. When done working, turn the Water Feed Switch 4.2. (Pic.1) OFF and
disconnect the water hose.
3. Push the boiler ON button 5.5 (Pic.2), the pump will start lling the boiler and
LED 5.3 (Pic.2) lights up.
4. When the pump stops LED 5.3 (Pic.2) goes out and the heating phase begins,
lasting approximately 5 minutes. During the heating phase, LED 5.4 (Pic.2) will
continue to blink.
5. When LED 5.4 (Pic.2) stops blinking and stays on, the machine is ready for
use. During use this light will often blink to show that the heating elements are
cycling on.
6. Insert the hose into the hose connection socket 1, 2 or 9 (Pic.1) (depending on
the application), ensuring that it is securely tted.
7. Fasten accessories to lances by rmly pushing them on to the tip (nozzle)
3.3 (Pic.3)
8. Pull the trigger 3.1 (Pic.3) on the hand-grip to start the steam output and direct
the steam jet towards the area to be cleaned.
9. Control steam output by selecting the two hose output ‘A-A’ or single hose
output ‘B’ on the steam output selection switch 4.4. (Pic.1).
10. With the output power selection switch 4.3. (Pic.1), change between 36kW and
72kW power output (one hose or both hoses).
NOTE: When knob 4.3. (Pic.1) is in the 36kW position, steam will only be released
from position 1. When knob 4.3. (Pic.1) is in the 72kW, steam will be released from
both 1 and 2 outputs OR the optional hose that connects to port ‘B’, NOT both.
NOTE: Before beginning steam cleaning operations, evacuate the condensation
left inside the steam hose into a bucket or other suitable place.
WARNING: In case of danger, injury of the operator, leakage of steam or anything
that makes it difcult to regularly turn the machine off, immediately hit the
emergency OFF button 3 (Pic.1). The switch will remain in the off position until
manually reset by turning the switch so that it pops back up! Reset ONLY after
having removed the cause of malfunction. See the troubleshooting section!

AFTER USE:
1. Turn off the boilers 5.5 (Pic.2).
2. Turn the output power selection switch 4.3. (Pic. 1) to the 36kW position.
3. Turn the steam output selector switch 4.4. (Pic. 1) to the ‘B’ position.
4. Do one of the following:
•Install the hose into 72 kW connection
manifold 9.
•Pull the trigger until the pressure on
both pressure gauges read 6 BAR.
•Turn the steam output selection knob
to ‘OFF’.
•Pull the trigger to relieve the steam
from the hose.
•Turn the steam selector output 4.4. to
position ‘OFF’.
•Turn the boiler steam drain valve 10
into the ‘ON’ position using the k
eys provided.
•If you are not already doing so, put on
heat protection gloves and
safety glasses.
•Remove the cap from the top ball valve
in the back of the steamer labeled
Boiler Steam Drain Valve.
•Then slowly open the ball valve.
•Wait until both pressure gauges read
6 BAR.
5. Turn off the main power 8 (Pic.1). Now wait
30 seconds.
6. Turn the machine back on 8 (Pic.1). Turn the boilers back on 5.5 (Pic.2). Wait for
the pump to stop.
7. Turn off the boilers 5.5 (Pic.2) as soon as the pump stops. Release steam until
the unit reaches 6 bar again. Turn off the main power 8 (Pic 1).
8. Dry all accessories and store them in a dry environment.

MAINTENANCE
ATTENTION: Scheduled maintenance should be done every 6 to 12 months or
more often if used very heavily and/or if the water is very hard. Make arrangements
with Goodway for professional maintenance and assistance. Only trained persons
are allowed to perform the below procedure!
The amount of carbonates in the water (chalk, salts and other minerals) determine
the hardness of the water you use with this machine. When water is heated up these
carbonates will “fall out”, that is they will become small particles that in the worst
case can encrust your boiler, the heating element and other components. Please
clean your boiler as described below regularly, more so if you have hard water
from the tap. Do not use completely demineralized or distilled water with your
machine because such water contains no minerals and carbonates and could lead
to malfunction!
DANGER: If any maintenance is going to be done, ALL PRESSURE must be bled
from the boilers before starting any work. (See page 9 for instructions on bleeding
the boiler)
DANGER: Wear protective clothing, gloves and glasses while operating the below
procedure, the hot water can cause injuries!
DANGER: Remove electrical power before servicing per local “Lock out/ tag out”
procedures or the equivalent.
CLEANING THE BOILER:
Perform this task at least every month, but ideally at the end of each working week!
DANGER: Never bleed the boiler as long as any pressure is still inside the boiler!!!
1. Make sure the water inside the boiler is not hot.
2. Gently rock the machine to agitate carbonate deposits in the boiler.
3. Open the drain valve over a gully/drain or a container with a suitable capacity
to catch the water from the boiler.
4. Empty the content of the boiler while gently shaking the machine.
5. Close the drain valve.

Boiler Descaling: Chemical scale removal may be necessary depending on use and
water quality, contact Goodway Technologies for recommendations.
Inspect and replace the water lter as necessary:

connection with some silicone.
No steam output but the machine is
in pressure.
Make sure the manual output valve
is open.
Machine heating time too long. Remove scale from boiler as
described in the maintenance section.
