en ENGLISH
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.
8. Maintenance
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).

9. Troubleshooting
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.
