Drawing in water from tank

When you suction water out of an open container you should

–disconnect the water inlet at the pump head.

–unscrew the top supply hose to the water tank and connect it to the pump head.

–use a water suction hose with a minimum diameter of 3/4" provided with a vacuum filter.

*Until the pump sucks up water you should:

–turn the pressure and flow regulation to MAX.

–close the metering valve for the cleaning agent.

–Never suction up water out of a potable water tank.

–Never suction up solvent-bearing liquids such as paint thinner, benzine, oil or unfiltered water. The seals in the unit are not resistant to solvents. The mist of solvents is highly inflammable, explosive and poisonous!

Mains connection

Refer to technical data and rating plate for connected loads.

Whenever socket is changed, check direction of rotation of motor

If direction of rotation is correct, powerful jet of air will be felt at exhaust-gas opening of burner. If the direction of rotation is wrong: Change the poles at the unit plug. See figure 16.

If an extension cable is used, this should always be fully uncoiled and have an adequate cross- section.

Switch the unit on

Set the unit switch (item 23) to "I"

The ready for working indicator lamp (item 29) is lit

The temperature regulator (item 24) must be at setting "0", since it is otherwise possible that the burner switches itself on

Unit starts up briefly and is switched off as soon as operating pressure is reached.

*Turn the unit off immedediately if during its operation the indicator lamps

(item 25-item 28) light up. Eliminate fault, refer to Faults.

Figure 8 Release handgun

Actuation of handgun switches unit back on again.

Bleed pump if no water emerges from high- pressure nozzle. Refer to Faults "No build-up of pressure by unit"

Setting cleaning temperature

Set the temperature regulator (item 24) to the required temperature

30°C to 90°C

Hot water cleaning

100°C to 150°C

Clean with steam, with steam nozzle - 4.766-023, at HDS 1195 and HDS 1295 - 4.766-024

Setting operating pressure and flow rate

Figure 9

Turning regulator clockwise: Increases operating pressure (MAX)

Turning counter-clockwise: Reduces operating pressure (MIN)

Servopress control

Set the temperature regulator (item 24) to max. 98°C.

Set regulator to maximum operating pressure.

Figure 8

Operating pressure and flow rate can be set at handgun.

Set pressure on unit if use is to be made of reduced pressure for a lengthy period. See figure 9
