The pump can be switched on/off in "Mode A"

using the button (4) also. Dry-running protection is

also the same as in normal mode.

Automatic domestic water system

(device designation HWA...)

Functional principle: The device switches on when

the removal of water causes the water pressure to

fall below the switch-on pressure; it switches off

again when switch-off pressure is reached.

1. Insert mains plug.

2. Fill pump if necessary - see section .6.7

3. Switch on the device - see section 7.1).

4. Open the discharge line (open water tap or

spray nozzle).

5. Check that water emerges! The device is now

ready for operation.

Domestic water system

(device designation HWW...)

Functional principle: The device switches on when

the removal of water causes the water pressure to

fall below the switch-on pressure; it switches off

again when switch-off pressure is reached. The

pressure vessel contains a rubber bellows, which

is under air pressure (pilot pressure) when deliv-

ered; this permits the removal of small volumes of

water without the pump starting up.

1. Insert mains plug.

2. Fill pump if necessary - see section 6.7.

3. Switch on the device - see section 7.1).

4. Open the discharge line (open water tap or

spray nozzle).

5. Check that water emerges! The device is now

ready for operation.

Danger! Prior to all servicing:

-Unplug mains cable.

- Ensure that the device and connected accesso-

ries are depressurised.

- Repair and maintenance work other than

described in this section should only be carried

out by qualified specialists.

8.1 Regular maintenance

- Check device and accessories, in particular,

electrical and pressurised components, for

damage and repair if necessary.

- Check suction and discharge lines for leaks.

- If the conveying capacity decreases, clean intake

filter and filter element (if installed) and replace if

necessary.

- Check the pilot pressure of the pressure vessel

(7) (depending on features) and increase it if

necessary (see section 9.4 Increasing pilot pres-

sure).

8.2 Cleaning the intake filter (depending on

features)

1. Unscrew the cover (16) (using the key if neces-

sary (15)).

2. Pull the filter unit (17) upwards vertically to

remove.

3. Disassemble the filter unit: Hold the cup (18),

turn the filter (19) in a clockwise direction and

remove it from the cup (bayonet lock).

4. Place the cup (18) under flowing water to clean

and use a soft brush to clean the filter (19).

5. Assemble again in reverse order. In doing so,

ensure that the filter unit (17) is fully inserted.

8.3 Danger of frost

Caution! Frost (< 4 °C) destroys the pump

and accessories as both always contain

water!

- If there is a danger of frost, disassemble pump

and accessories and store in frost-free condi-

tions (see following section).

8.4 Removing and storing device

- Switch off appliance. Unplug mains cable.

- Open the discharge line (open water tap or spray

nozzle), allow water to drain off completely.

- Completely drain the pump (6) and vessel (7) by:

- unscrewing the water drain screw (9).

- Remove suction and discharge lines from

device.

- Store device in a frost-free room (min. 5 °C).

Danger!

- Prior to all servicing:

- Unplug mains cable.

- Ensure that the device and connected accesso-

ries are depressurised.

9.1 Pump is not running

• No mains voltage.

- Check on/off switch, cables, plug, socket and

mains fuse.

• Mains voltage too low.

- Use an extension cable with sufficient

conductor diameter.

• Motor overheated; motor protection relay

tripped.

- After cooling the pump will switch on again.

- Guarantee sufficient ventilation, keep air slots

free.

- Observe maximum supply temperature.

• Motor hums, but does not start.

- With the motor switched off, insert a screw-

driver or similar object through the air slots on

the motor and turn the fan impeller.

• Pump clogged or defective.

- Disassemble and clean pump. Clean diffuser,

replace if necessary. Clean impeller, replace

if necessary. See section 11.

9.2 Pump not drawing in correctly or run-

ning very loudly:

• Insufficient water.

- Ensure there is a sufficient water supply.

• Pump not sufficiently filled with water.

-See section 6.7.

• Suction line leaking.

- Seal suction line, tighten screw-couplings.

• Suction height too high.

- Observe maximum suction height.

- Insert check valve, fill suction line with water.

• Intake filter (accessories) obstructed.

- Clean, replace if necessary.

• Check valve (accessories) blocked.

- Clean, replace if necessary.

• Water discharge between motor and pump,

shaft seal leaking. (Minor discharge of water

(max. approx. 30 drops per day) is normal with

the use of shaft seals).

- Replace shaft seal. See section 11.

• Pump clogged or defective.

-See section 9.1.

9.3 Pressure too low or pump runs continu-

ously:

• Suction line leaking or suction height too high.

-See section 9.2.

• Pump clogged or defective.

-See section 9.1.

• HWW...: Pressure switch incorrectly adjusted.

- Read off switch-on and switch-off pressure at

the pressure gauge (11) and check values

(see section 13 Technical Specifications). If

an adjustment is necessary, please contact

Metabo Customer Service. See section 11.

• HWW...: Pump starts up even after removal of

small volume of water (approx. 0.5 l).

- Check whether the pilot pressure in the pres-

sure vessel is too low. Increase pressure if

necessary. See section 9.4.

• HWW...: Water is running out of the air valve.

- Rubber bellows in pressure vessel leaking,

replace it. See section 11.

• P 6000 Inox: The LED (3) lights up in blue.

- "Mode A" is enabled. See section 7.2

9.4 Increasing pilot pressure (only HWW...)

If – in the course of time – the pump starts up even

after the removal of a small volume of water

(approx. 0.5 l), the pilot pressure in the vessel must

be restored.

Note:

The pilot pressure cannot be read off at the

pressure gauge (11).

1. Unplug mains cable.

2. Open the discharge line (open water tap or

spray nozzle), allow water to drain off

completely.

3. Unscrew plastic cap on front face of pressure

vessel; the air valve is located behind it.

4. Mount air pump or compressor hose with a

"tyre valve" connection and pressure gauge on

the air valve.

5. Pump up to the specified pilot pressure (see

section 13. Technical Specifications).

6. Connect device again and check operation.
