Pump guarantees optimum filling level

NOTE

Automatic filling with pump (optional)

The pump automatically fills the tank with the optimum quantity of water. There are no idle phases due to required cooling-down phases as when filled by hand.

As soon as the water level in the tank goes below a certain level, the pump automatically refills the tank up to the optimum level.

During the filling process the LED “pump min“ is active

(illustration 3.10.). As soon as the maximum filling level in the tank is reached, the LED “pump max.“ (illustration 3.10.) turns on.

Risk of damage caused by water in case of loosened water tube!

Shut down the water supply after operation or when the unit is unattended.

NOTE

NOTE

Risk of damage to the pump due to running dry. The water supply valve must remain open during operation.

Filling of the unit

5.2.1

Mounting

Connection the pump at the tap water supply

Ensure that the Elmasteam is switched off. The maximum water pressure must not exceed 4 bar.

1. Connect the preassembled pump supply hose (illustration

5.2.1.A.

) to the water tap: you need an additional ½“ hose of the required length. Fasten this hose between the adapter piece (illustration 5.2.1.B.) and the water tap by means of hose clamps.

Please ensure secure and safe fastening of the hose.

2. Fill the tank with approx. 1 litre of water (manual filling) (see

section 5.1.

).

This prevents a dry running of the heating during initial

operation

.

For initial filling of the Elmasteam via the pump it is recommendable to open the screw cap of the filling duct to release the air from the system. As soon as the LED „pump max.“ on the unit turns on the screw cap must be closed.

3. Open the tap of the water supply.

Filling of the unit

5.2.2

How to proceed

Connection the pump at a water tank

The conductance of softened water must have a minimum value of 15 μSiemens.

If the unit cannot be connected to the tap, the pump can also be connected to an external water tank. The suction power of the pump is designed to a max. water column of 1 m, i.e. an external water tank for the water supply can be arranged at a distance of max. 1 meters from the unit.

Connect the pump supply hose (illustration 5.2.2.1.) to a suitable and sufficiently filled water supply tank.

1. Immerse the tube end into the water supply tank and secure the tube against sliding.

2. Fill the pressure tank with approx. 1/2 litre of water (by hand)

(see section 5.1.). This prevents dry running of the heating during initial operation.

For initial filling of the Elmasteam via the pump it is recommendable to open the screw cap of the filling duct to release the air from the system.

3. Open the ball valve for the ventilation of the system (see

illustration 5.2.2.2.B.

).

The piping system must be de-aired for each new suction cycle. Otherwise there is a risk of damage to the pump.

4. Switch the unit on (switch position “on“). The unit automatically starts filling and heating up of the pressure tank. Air escapes from the ball valve. When water starts flowing out of the ball valve the piping system is completely de-aired.

5. Shut the ball valve as soon as water starts flowing out (see

illustration 5.2.2.2.A.

).

6. When the LED „pump max.“ at the unit is lighted, close the screw cap at the pressure tank.

NOTE

Risk of damage to the pump due to dry running! Ensure that the water tank is always sufficiently filled.

The steam/compressed air outlet at the fixed nozzle is controlled by the foot-activated switch.

There are two switch positions:

Activates the compressed air at the nozzle. (Optional). Only if the unit is correctly connected to a compressor on the back of the housing.)

Activates steam at the nozzle.

Keep the cleaning item at least 1 cm from the nozzle when holding it into the steam zone. Check the cleaning result at short intervals (visual inspection). Check sensitive surfaces of cleaned items for possible damage.

If the unit is connected to an external compressed air supply, the nozzle can be used for compressed air, too. The cleaning item can be dried with compressed air.

Connection

NOTE

Connect the compressed air duct

Operation with compressed air (optional)

After the cleaning of the item, there is a residual humidity on the material which can easily be dried by means of compressed air.

The units are fitted with to norm connection sockets for compressed air at the back (optional) (connection see illustration

3.11.1 B and D

). If a compressor is available the unit can be connected to the compressed air system. The Elmasteam can now be switched over between steam and compressed air at the hand piece or by foot activator.

For this a suitable Teflon tube (diameter 6 mm) is required).

The unit must be connected to a compressed air supply system at max. 6 bar!

Keep the compressed air free of dirt particles!

Push a suitable compressed air duct into the connection socket as far as it will go (see illustration 6.1.1.).

The connection coupling inside the compressed air connection socket automatically fixes the duct.

Remove the compressed air duct

Illustration 6.1.1. Connect the compressed air duct at the correct connection socket

Press the blue flexible coupling of the compressed air connection

(see illustration 6.1.2.A.) and pull the compressed air duct (B) out of the connection socket at the same time.

Maintenance / care / repair

Maintenance works requiring the opening of the unit are not necessary.

Read and observe the following instructions before carrying out any maintenance works.

Visual inspection

Decalcify the unit

CAUTION

Preliminary

How to proceed

Check the mains cable and all electric connections for damage regularly. For reasons of safety, replace all damaged cables and connections before any further operation.

If the unit is operated with calciferous city water (tap water) there is a risk of calcification of various unit components. To prevent damages from the unit caused by calcification rinse the pressure tank at least once per month.

If the unit is continuously operated with tap water, a certain amount of lime will collect in the pressure tank depending on the water hardness. The lime will sit on the walls of the pressure tank and on the heating element. Lime particles that come loose may choke unit components such as valves and nozzles.

The manufacturer cannot be held liable for any damages on the unit caused by maintenance carried out improperly or not at all!

Risk of causticization!

Do not fill decalcifyer or other chemicals into the unit.

For decalcification use water only.

The unit must be cooled down before decalcification can be carried out (depressurize the unit). The pressure tank should be filled up to maximum level.

1. Unscrew the blind screw at the ball valve with a fork wrench by turning it anti-clockwise.

2. Screw the maintenance tube (included in delivery) to the ball valve (illustration 3.11.F).

3. Switch the unit on and let it heat up.

4. Observe the pressure increase on the manometer. As soon as a pressure of 3 bar is reached, turn the function switch to

“off”.

5. Direct the free end of the maintenance tube into a bucket filled half with water.

Hot water. Risk of scalding!

Wear gloves when handling the tube.

6. Direct the tube into the bucket and slowly open the ball valve; the remaining water from the tank is swept through the tube together with the lime.

7. Rinse the pressure tank again with 5 – 10 litres of water.

8. As soon as the tank is completely empty, close the ball valve and remove the maintenance tube.

9. Retighten the screw at the ball valve with the fork wrench by turning it clockwise.

7.2 Repair

Should any repair works be necessary please contact your supplier or the manufacturer of the unit.

Repair works must be carried out by specialized personnel only.

Risk of electrocution by live parts in the unit!

Separate the unit from the mains for all repair works.

CAUTION

CAUTION

Risk of scalding due to released steam!

Do not open the screw cap at the filling duct with a pressure above 0 bar!

Do not dismount pressure-carrying parts from the unit with a pressure above 0 bar!

Let the unit cool down before opening!

Risk of scalding due to hot surfaces!
