OPERATING INSTRUCTIONS
A 3 Applications
Steam Cleaner EWL 5839 assists in the leaning of metal and por elain work, as well as for boiling out and removal of grease from
instruments in all pro edures of dental te hnology. You have the hoi e of leaning the obje t with dry or also wet steam. It is possible to
swit h to wet steam at any time.
A 4 Preparing for installation
A 4.1 Unpacking/Transport
Remove all pa king materials, and set the unit on a firm and flat surfa e. Alternatively, use the in luded wall bra ket to mount it on the
wall. Che k the in luded a essories.
Before moving the unit, ensure that the ele tri al supply is dis onne ted.
When shipping the unit, pa k it in a suitable ontainer to prevent transport damage.
A 4.2 Installation / Storage
• Set the unit on its final pla e, horizontally level, or mount it on the wall.
• When wall mounting, ensure that the wall is apable of arrying the load. (use the following sket h as a guide for drilling)
• Ensure that the working and operating areas are not ramped (observe unit dimensions) - do not set up outside!
• For long-term storage, prote t the unit against dampness and dust.
• Install the following onne tions before putting the unit into operation:
- Conne t the water supply hose to a fau et, with ba k-flow valve and ventilation (as for a washing ma hine)
- Fix the supplied drainage hoses: a) under the pressure hamber, and b) to the ba k of the olle ting tray.
- Guide the hoses into a heat-resistant bu ket or a sink, as very hot water drains.
- Conne t the footswit h with the spe ial so ket on the right side of the housing.
- Plug the unit into an ele tri al so ket ompatible with the voltage of the unit.
No unwanted spraying is possible, as the footswit h ontrols two separate ir uits.
Before operating the steam leaner, put on heat-resistant gloves and safety glasses.
If the unit is not to be used for a lengthy period, remove the ele tri al plug and shut off the water supply.

A 5 Preparing for operation
- Open the water fau et.
- Press the main swit h (green) – unit fills automati ally with water, and starts to heat up.
- Only with a new unit, or alternatively after emptying the pressure hamber (rinsing pro edure):- after pressure has rea hed approx. 4 bar, ventilate
the hamber on e – point the spray nozzle towards the olle ting tray and at the same time a tivate the footswit h until the manometer drops to zero.
After about 15 minutes the operating pressure rea hes 6 bar, and the unit is ready for operation.
A 6 Operation
- Press the keyboard to sele t either dry or wet steam.
- When sele ting wet steam, hoose the moisture ontent by turning the s ale knob from position “0” (no moisture) to position “5” (maximum
ontent)
- Pi k up the nozzle, and ontrol the steam output by the footswit h.
Attention! Danger of s alding!
• Hold the nozzle only at the handle.
• Do not dire t the spray at people.
• Steam an be as hot as approx. 164° C, therefore spray only in the dire tion of the olle ting tray or the sink.

A 8 Care of the unit
Before leaning or maintaining the unit, let it ool down!
A 8.1 Cleaning
In order to ensure trouble-free operation, the unit should be leaned at regular intervals, using a mild detergent with a sponge or soft loth.
Do not use any hemi als.
The olle ting tray an be removed from the unit for leaning.
One version of the unit omes with a olle tion drawer and lid – to lean, simply pull it out.
The nameplate must always be legible and never be removed.
A 8.2 Maintenance
An integral part of the KaVo Steam Cleaner is a spe ial te hnique to prevent build up of lime, therefore, at least on e a week, minor lime
parti les should be flushed out. It is not ne essary to drain the water.
However, if it does become necessary to drain the chamber, please note the following:
Che k the manometer to ensure that the unit has ooled down, and that the drain hose leads to a heat-resistant bu ket or to a sink.
For your own safety, it is re ommended to permanently install the drain hose as water and steam from a unit that has not ooled down is
very hot – approx. 164° C.
Using the square so ket wren h, turn the drainage valve from its lo ked position 90° in an anti- lo kwise dire tion – at the same time
pressing on the footswit h until no more water flows.
Re-lo k the valve by turning 90° in a lo kwise dire tion.
An additional feature advises when rinsing is necessary:
If you have not arried out the weekly rinsing, after 200 hours of use an ele troni operating-hours meter warns that rinsing is ne essary.
This is indi ated by the permanent flashing of the yellow dry/wet-steam ontrol light together with the red low-water level ontrol light.
The meter an be set ba k to “0“ (see RESET)
Further use of the unit is possible, however, without problems.
Rinsing procedure (summary only – see stic er on left side of housing)
Rinsing the unit is best arried out in a old ondition, before use. Otherwise, swit h unit off and let it ool down until it is virtually
pressure-free (under 2 bar).
Open the water fau et, and swit h the unit on.
Using the square so ket wren h, open the drainage valve on the left side of the housing by turning a omplete 90° to the se ond stop. In
the pro ess, press the safety-lo k button at the right of the valve.
Pressing on e partly opens the valve (safety lo k – danger of s alding!); to ompletely open the valve, press the button again.
Hold the bla k rinsing key at the left of the valve pressed down until only lear water flows out of the drainage hose. Close the valve by
turning it ba k 90°.
Now pro eed in a ordan e with A 5 (Putting into operation) and A 6 (Operation).
Re-setting the operating-hours meter = RESET
Swit h the unit off.
Hold the dry-steam key pressed – at the same time swit h unit on.
Operating hours ount starts from zero.
The safety valve for the pressure hamber must be tested for proper fun tion at regular intervals by a Servi e Te hni ian!
