6 Before Starting
6.1 Transport
Before transporting the unit, ensure that it has been unplugged from the power socket.
Make sure that it is packed correctly in order to avoid accidental damage.
Be sure to check for any transport damage when unpacking the goods. Note
down any damage if found.
6.2 Installation
Open the box, remove the packing materials, and carefully lift out the unit and accessories.
Check the included accessories.
The unit must stand on a steady and even surface or may be mounted to a stable wall by
means of the mounting kit (available as accessory). If mounting the unit on the wall, make
sure that the wall is strong enough to take the weight. For further information please see
6.4 of this manual.
Install the unit in a place where it will not block the working area and the
functionality (take the dimensions into account).
Please see that the louvres are not set because air circulation (heat flow) is
absolutely necessary.
Do not install the unit outdoors or in places without proper ventilation.
Before start-up, be sure the unit reaches room temperature.
7

6.3 Storage
If the unit is to be stored for an extended period, protect it from moisture and dust.
The unit location is very important when it comes to workplace safety, even if it is only to
be set up there for a short period. The room should be dry, well ventilated and vibration-
free. An even temperature and wooden supports also help.
The unit should not be stored or set up outdoors.
6.4 Mounting Instruction Fastening Set for Wall Mounting Wasi-Steam Classic II

Carefully hook in the unit. Check, whether the unit hangs loosely (i.e. moving back and
forth on the screws). If this is the case tighten the 6x50 screws until the unit hangs
securely.
Finally tighten the securing bracket. First at the wall, then tighten the screw on the unit
itself. (Figure 4)
7 Start-up/ Installation
Before you use the steam cleaner, please put on heat-resistant gloves and wear
safety goggles.
Switch the unit off if it will not be used for an extended period.
Note: Optimal and fast pressurization is carried out only if the adjusting knob is in the
"max." position, since the heater with this is activated via a push button switch, i.e.
immediately at the start of every blasting action.
However in case of the pressure choice options “less than max.”, the heater is activated
via a thermostat, i.e. even in case of a massive decrease in pressure it may take several
minutes until the heater is activated due to residual heat of the container for example.
Therefore this setting “less than max.” is preferable only in case of occasional work.

•Open the screw top (5) of the container carefully while pressing down the screw top
•Fill with at most 2 litres of water
•Operation with distilled / softened water is possible and is recommended
•Tighten container screw top (5) sturdily again (hand-screwed)
•Connect power plug
•Switch on main switch (4)
•Choose pressure range from 0 – 5 (max. = 5 bar) with adjusting knob (3)
•Heat-up phase approx. 30 minutes (full container)
•Briefly deaerate the unit after approx. 15 minutes by operating the steam gun
•If the heating light (2) turns off, the unit is ready for use. Now steam blasting via the
gun is possible by operating the pushbutton until the temperature delimiter (6)
activates (button under black cap on the right side of the unit) and the red light (1)
lights up
•Then proceed by referring to point 8.1.1 "refill water"
8 Operation
8.1 General Operating Instructions
All instructions for using the unit, whether in verbal or written form, are based on our own
experience and experimentation and can only be regarded as guidelines.
To avoid an unintentional interruption of use (cooling down period
approx. 45 min.), the unit should be refilled every morning in a cold
state (take fill level into account, or else the container will be
overfilled).
Note: Do not refill more than 2 litres of water, if the red light (water
shortage) lights up (otherwise the container will be overfilled).
Operation with distilled / softened water is possible and is
recommended .
14

8.1.1 Refill the unit with water
●After the red light (1) lights up, wait approx. 45 min. (cooling down
period) until you refill again, or else there is a risk of scalding as long as
the temperature remains above 100°C
●Container must be pressureless; produce a pressure balance via the jet
nozzle by operating the steam gun
●Only now open the screw top (5) of the container carefully while pressing
down the screw top
●Refill water ( 2 litres at most )
●Operation with distilled / softened water is possible and is recommended
●Fully tighten the screw top (5) of the container again (hand-screwed)
●Switch on the temperature delimiter (6) (button under black cap on the
right side of unit) again as follows; first unscrew the black cap, then push
in the pushbutton, the red light (1) goes out and the unit heats up to the
adjusted pressure. Finally, screw the black cap back on
●Heat-up phase (see p. 14)
●Operational; i.e. steam blasting via the gun by operating the pushbutton is
possible until the temperature delimiter (6) activates again and the red
light (1) comes on

9 Troubleshooting
Fault Cause Solution
The red light (low
water) lights up and
the heating turns off
This is a safety
feature of the
steamer: Thermo-
safety switch
(temperature
delimiter 165°C) with
manual reset
Please see page 14/15.
No function, only the
main switch lights up
Devise fuse faulty Replace fuse and investigate cause; call
service if necessary.
Steam escapes from
unit
Safety valve has
opened because
pressure switch is
faulty
Turn off the unit immediately (unplug power
plug) and call service.
Hot water leaks from
the nozzle instead of
steam
Container is overfilled
with water
Operate gun until only steam escapes.
Lower amount of
steam than usual at
max. heating
Nozzle of the steam
gun is clogged or the
water level in the
container has
reached the minimum
level
Unscrew nozzle from gun and examine for
passage (caution risk of scalding!!) or refill
water (do not overfill!!).
Operation with distilled / softened water is
possible and is recommended.
Insufficient pressure
build-up
Tank seal is still loose
or O-ring is faulty
Check or replace tank seal.
No pressure in boiler Container empty but
red light or thermo
switch faulty or
container not empty
but heater or heating
regulator faulty
Check water level, refill if necessary and
check the thermo switch button. If still no
function, call service.
Operation with distilled / softened water is
possible and is recommended.
No steam when
operating the
pushbutton
Solenoid valve faulty
or clogged
When operating the gun's pushbutton, a
"clicking sound" is heard from the solenoid
valve. If this is the case the problem could be
resolved by cleaning the valve. Otherwise call
service.
If the above recommendations do not solve the problem, contact your dental depot
or our service department.

10 Care and Maintenance
10.1 Cleaning
Disconnect the power plug before starting any maintenance work.
The identification plate has always to be kept in easily legible condition and has
not to be removed.
Remove external dirt from time to time with some form of cold cleaner.
Use only cold cleaners to avoid damaging the paintwork or removing the lettering.
The equipment should be cleaned at regular intervals to ensure trouble-free
operation.
It requires only normal cleaning (sponge, damp cloth, mild detergent) and no further
chemical additives.
Please see 10.2.1 „Decalcification“
17

10.2 Maintenance
The Wasi-Steam Classic II should, depending on frequency of use, but at least twice a
year, be decalcified in accordance with the following instructions. Depending on water
hardness a more frequent decalcification could be required. Operation with distilled /
softened water is possible and is recommended. As a basic principle, the unit must always
be kept clean.
10.2.1 Decalcification
•Turn off the main switch and unplug the power plug
•Empty / pour out container in cold state
•Mix approx. 50 cc lime scale remover with 2 litres of water and fill into the unit
(depending on lime content, the ratio can be increased)
•Heating controller must be set just a little above 0 bar (heating on, but almost any
pressure)
•Close tank cap (hand-screwed)
•Switch on the unit and let it heat up briefly until the green light goes out
•Turn off the unit and allow the lime scale remover to react for approx 8 hours (lime
remover should not react longer than 12 hours)
•Pour out the solution and rinse with clear water (approx. 1 litre) at least two times by
shaking the unit
•Refill only maximal 2 litres of water (otherwise the tank could overfill)
•Operation with distilled / softened water is possible and is recommended
•The steam cleaner is now ready for operation
10.3 Repairs
Servicing or repairs to the unit has only to be carried out by qualified technicians.
Only original spare parts are to be used. Responsibility for the product is voided
