Exclusion of liability

There is a risk of scalding from hot steam in the case of incorrect operation!

Do not open pressure tank screw cap on the filling tube of the pressure tank at pressure above 0 bar!

There must not be any unauthorised third persons in the range of the steam jet. Handle hot steam carefully to avoid injuries.

The pressure tank screw cap must be correctly sealed during operation.

The outlet of the safety pressure valve is located in the tank cap. Attention! In the event of any possible tripping of the safety pressure valve, steam discharges on the underside of the tank cap.

The outflow of steam at high velocity causes electrostatic charge generated by friction to accumulate on the nozzle as well as on the product to be cleaned. The electrostatic charge developed on the handpiece is continuously dissipated via the ground connection of the device. Depending on external conditions such as insufficient conductivity of the floor and/or shoes, dissipation of electrostatic charge of the product to be cleaned may be impaired. This absolutely harmless but unpleasant state can be sensed as “tingling” or “electric shock” (a similar effect may occur, for example, in carpets or velvet car seats). The discharge that takes place here can be observed as a visible spark discharge from the product to be cleaned to the handpiece. It is recommended in such cases to ground the product to be cleaned or, if necessary, the wrist of the user (e.g. with an ESD wrist strap).

Steam jet cleaners can cause unpleasant noise levels during operation. Use personal hearing protection during the stay in the work area.

Perform the maintenance work described in this manual (chapter

7) at regular intervals to guarantee the function and safety of the

machine. Repairs must only be carried out by authorised qualified personnel.

Always unplug the mains plug before servicing or opening the machine.

Only original parts are permitted to be used for repairs. Close the water supply of the pump at the water tap after operation

or if the machine is unsupervised. The machine is only permitted to be stored and transported upright when the pressure tank is filled; otherwise residues can clog the

steam valve.

The user is responsible for checking the cleaning result. Elma Schmidbauer GmbH shall not accept any damage and warranty claims if:

5 Filling the machine

5.1 Requirements for water quality

Basically, the machine is only permitted to be operated with drinking water or demineralised water*.

*Elmasteam 45 basic P-HP with integrated pump: If the conductivity of the water <15µS/cm or if the conductivity is unknown, 1 level teaspoon of table salt must be added to the pressure tank during initial commissioning (one-time only!). Dissolve the salt in a glass of water and fill into the filling opening.

The salt does not pass into the steam phase and thus remains in the machine; therefore the addition is only necessary during initial commissioning or after decalcification of the machine (see chapter

7.2)

The Elmasteam should preferably be operated using demineralised water. This can significantly increase the service life of the machine.

The water quality significantly affects the maintenance intervals (see chapter 7).

5.2 Manual filling

Start the filling process from point 4 when the machine is depressurised.

First reduce the pressure when the machine is warmed up.

Risk of scalding from discharging steam!

Do not open pressure tank screw cap when the steam pressure

CAUTION

is above 0 bar.

1. Let residual steam pressure escape through the steam nozzle.

1.1. Machine version with hand piece:

1.1.1 Fix the hand piece.

Ensure that the discharging steam does not present any hazard for persons or equipment.

1.1.2 For draining the residual steam pressure, keep the foot

switch pressed until no more steam escapes (approx. 40 50 seconds).

1.2 Machine version with fixed nozzle:

1.2.1 For draining the residual steam pressure, keep the foot

switch pressed until no more steam escapes (approx. 40 50 seconds).

2. Switch off the machine at the mains power switch (0) (Reset).

3. After complete depressurisation, the machine must still cool

down for approx. 5 minutes to prevent spontaneous steam formation during filling.

Fill pressure tank

CAUTION

Switch on the mains

Filling the machine

4. Open pressure tank screw cap slowly (an integrated pressure-

ventilation system lets a stem possibly still in the pressure tank escape sideways at the pressure tank screw cap during opening of the screw connection).

5. Place the sieve in the collecting basin (Fig.5.2.1 | 5.2.2).

Risk of scalding from discharging steam during filling! Let pressure tank cool down (see point 3)! Fill pressure tank slowly. Do not bend over the filling opening of the pressure tank during

filling.

6. Fill water slowly!

Note the maximum filling volume of the pressure tank capacity of approx. 3.2 litres.

7. Remove the sieve.

Wipe off water that has overflowed. Encrusted residues can impair the safety mechanism in the pressure tank screw cap.

8. Check the opening of the pressure tank screw cap. In the case

of recognisable clogging, replace the pressure tank screw cap for safety reasons.

9. Close the pressure tank screw cap by hand (hand tight).

10. Switch on the machine at the mains power switch ( I ). If the machine has preciously signalled a minimum fill level using

the red LED, this signal is reset by the power off and power on.

Filling the machine

Pump ensures

optimum fill level

ATTENTION

5.3 Automatic filling with pump (basic P-HP)

Risk of brackish water backflow into the water supply!

A system separator must be installed between the water connection on the building side and the Elmasteam to protect drinking water against non-potable water.

The operating company is responsible for the implementation of the measure.

The pump fills the pressure tank with the optimum filling amount of water automatically. No waiting time are produced due to necessary cooling down phases as for manual filling.

Risk of water damage from possible detachment of the water hose!

Close the water supply of the pump at the water tap after operation or if the machine is unsupervised.

Risk of water damage from overfilling of the pressure tank! Observe requirement for the water quality (see chapter 5.1).

1. Before the first filling, fill the pressure tank manually with

approx. 2 litres of water (see chapter 5.2).

It is expedient for the first filling of the Elmasteam using the pump to unscrew the pressure tank screw cap to let the air escape from the system.

2. Open the water tap for the water supply.

Check the hose connections for leaks and tightness.

3. Switch on the machine.

After approx. 10 seconds, the machine starts filling and heating the pressure tank.

4. Screw the pressure tank screw cap closed again after the

automatic filling. Further refilling is performed automatically during operation. Note in the case of incorrectly dimensioned softening cartridges in

the water supply line: When the solenoid valve for the water inlet closes, a natural rebound on the line occurs as is also produced when closing a water tap. This can result in damage in the case of too weakly dimensioned softening cartridges.

6 Handling in operation

Risk of scalding from hot steam! Act cautiously when steam discharge is activated.

WARNING

Avoid hazardous situations caused by unintended activation of the steam output.

There must not be any unauthorised third persons in the range of the steam jet during the steam spraying.

Lock the steam button using the red lock on the hand piece. Use of the actuation clamp for the hand piece is only authorised

for the pressure reduction process when the machine is switched off!

Danger from hot surfaces! Hot temperatures occur during operation at the steam

discharge nozzle and on the rear panel of the machine.

Put the machine into operation as described in chapter 4. Ensure that the pressure tank is filled before starting work.

Otherwise, fill the pressure tank as described in chapter 5. Switch on the Elmasteam at the mains power switch. The machine starts to build up pressure. Depending on the fill level, the operating pressure of 4.5 bar is

reached after approx. 15 - 20 minutes. The green LED indicator lamp signals the operational readiness.

The green LED indicator lamp can extinguish depending on the duration of the steam dispensing.

Handling in operation

Steam can continue to be dispensed during the reheating. Use a suitable aid for the safe holding of smaller workpieces. Before starting the cleaning, ensure that the workpiece to be

cleaned is suitable for this cleaning process. In particular, the thermal and mechanical load capacity must be taken into account.

Instruments must be resistant to steam.

Keep the workpiece at least 1 cm away from the nozzle in the steam zone. Check the cleaning success at short time intervals (visual inspection) and possible adverse effects on sensitive surfaces of the product to be cleaned.

The user is responsible for checking the cleaning result.

• the foot switch and the electrical supply line to the foot switch

• the steam hose, the hand piece and the steam button

• the pressure tank screw cap: replace in the event of internal

soiling and residues (chapter 7.4.1).

• O-ring of the pressure tank screw cap (chapter 7.4.2)

• also check water hose for correct fastening.

In the event of recognisable damage, the steam jet cleaner must be taken out of operation for safety reasons. Restarting is only authorised after repair has been completed.

7.2 Rinse pressure tank regularly

Depending on the local water quality, the maintenance intervals shown in the tables in chapters 7.2.1 | 7.2.2 are applicable.

Use the rinsing set (Fig 7.2) included in the delivery.

Never fill decalcifiers or other chemicals in the pressure boiler!

CAUTION

Also only use water for the decalcification process. Hazard from dangerous excess pressure in the machine!

Lime deposits can result in failure of the safety function of the safety valve. The owner is responsible for regular rinsing to descale the pressure tank.

Risk of scalding from damaged pressure boiler! Never fill decalcifiers or other chemicals in the pressure boiler!

These can attack and damage the material of the pressure boiler.

Also only use water for the decalcification process.

7.2.1 For water containing lime

Observe the safety instructions in chapter 7.2.

There is the risk of calcification of diverse machine components for operation with mains water containing lime (tap water). The pressure tank must be rinsed by the user in accordance with the table to avoid lime scale damage to the machine.

In the case of continuous operation with tap water, lime sludge and scale accumulate in the pressure tank depending on the hardness of the water. In addition, lime particles detaching from the pressure tank can clog diverse machine components such as valves and nozzles. Polished surfaces can be adversely affected (matted) by such lime particles.

The following cleaning intervals are specified, depending on the water hardness:

• Switch off the machine.

• Unplug mains plug.

• Let the machine cool down until it is depressurised (0 bar). After

complete depressurisation, the machine must still cool down for approx. 5 minutes to prevent spontaneous steam formation during rinsing.

• Have the maintenance hose included in the delivery ready.

1. Open pressure tank screw cap.

2. Push maintenance hose onto connection nozzle on the ball

valve.

3. Position machine so that the maintenance hose protrudes into

a sink or sufficiently large container and so that the ball valve can be operated.

Risk of scalding when draining possibly still heated residual water from the pressure boiler!

Wear gloves for holding the hose.

4. Open ball valve using a screwdriver (Fig. 7.2.1.2) and first

drain any still present residual water.

5. Connect rinsing set to a water tap (3/4" connection).

6. Using the hose from the rinsing set, spray the pressure tank in

circular movements.

Continue this process until no more lime residues are rinsed out of the pressure boiler.

In doing so, the water should be able to flow out of the pressure tank quickly*.

9. For machines that are operated with a pump in combination

with deionised water: Fill 1 level teaspoon of salt into the pressure tank after the rinsing (see chapter 5.1).

*If no water flows away despite opened ball valve, this is possibly

closed by lime residues: Remove maintenance hose and clear the opening in the ball valve using a thin object.
