Drilling Template Description
The mounting instruction requires drilling holes as indicated in the following template. Ensure the wall is suitable for mounting a device (aerated concrete walls and drywall can be problematic).
- Drill holes for wall mounting:
- Two holes spaced 140mm apart, with a depth of 55mm (Ø8mm drill bit).
- One hole positioned 70mm below the center of the top two holes, with a depth of 30mm (Ø5mm drill bit).
- The total vertical distance between the top and bottom mounting points is 260mm.
Securing Anchors and Screws
- Secure the enclosed screw anchors (S8 for the top two holes, S5 for the bottom hole) as shown in Figure 1.
- Screw the 6x50 screws into the two upper holes, maintaining a distance of 6-7 mm from the wall (Figure 2).
Attaching the Securing Bracket
- Screw the securing bracket to the Wasi-Steam Classic as shown in Figure 3.
- Do not fully tighten the Phillips head screw yet, as the securing bracket needs to be movable.
- Carefully hook the device onto the bracket. Check if the device hangs loosely (moves back and forth). If so, tighten the 6x50 screws until the device hangs securely.
- Finally, tighten the securing bracket. First at the wall, then tighten the screw on the device itself (Figure 4).
7 Start-up / Installation
⚠️ Before you use the steam cleaner, please put on heat-resistant gloves and wear safety goggles.
ℹ️ Switch the unit off if it will not be used for an extended period.
Note: Optimal and fast pressurization is achieved when the adjusting knob is in the "max." position. In this setting, the heater is activated via a push-button switch, immediately at the start of every blasting action. For pressure choice options (1-4), the heater is activated via a thermostat. This means that even with a significant decrease in pressure, it may take several minutes for the heater to activate due to residual heat in the container. Therefore, this setting is preferable only for occasional work.

8 Operation
8.1 General Operating Instructions
All instructions for using the unit, whether verbal or written, are based on our experience and experimentation and should be regarded as guidelines.
ℹ️ To avoid an unintentional interruption of use (cooling down period approx. 45 min.), the device should be refilled every morning in a cold state (take fill level into account, or else the container will be overfilled).
ℹ️ 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 recommended.
- Open the screw top 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 sturdily again (hand-screwed).
- Connect power plug.
- Switch on main switch (4).
- Choose pressure range from 1 – 4.2 according to the scale or choose max. with the adjusting knob (3).
- Heat-up phase: Approx. 30 minutes (full container).
Briefly deaerate the device after approx. 15 minutes by operating the steam gun. If the heating light (2) turns off, the device is ready for use. Now steam blasting via the gun is possible by operating the pushbutton until the temperature delimiter activates (button under black cap on the right side of the device) and the red light (1) lights up.
Then proceed by referring to point 8.1.1 "refill water".
8.1.1 Refill
⚠️ 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 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 of the container again (hand-screwed).
- Switch on the temperature delimiter (button under black cap on the right side of the device) again as follows: first unscrew the black cap, then push in the pushbutton, the red light (1) goes out and the device 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 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 | Device fuse faulty. | Replace fuse and investigate cause; call service if necessary. |
| Steam escapes from device | Safety valve has opened because pressure switch is faulty. | Turn off the device 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. |
ℹ️ If the above recommendations do not solve the problem, contact your dental depot or our service department.
