• If the pump capacity lessens clean
suction strainer and filter cartridge (if
installed), replace if necessary.
7.2 Danger of freezing
A
Caution!
Frost damages the pump and
accessories, as both always contain
water!
• When there is danger of freezing,
dismount equipment and accesso-
ries and store at a freeze-proof loca-
tion (see below).
7.3 Equipment dismounting
and storing
1. Switch equipment OFF and unplug.
2. Open pressure line (open tap or
spray nozzle) and drain water com-
pletely.
3. Drain pump completely; to do so
remove the drain plug from the
pump
4. Disconnect suction and pressure
lines from the equipment.
5. Store equipment in a frost-free
space (at least 5 °C).
A
Danger!
Prior to all servicing:
− Switch Off.
− Unplug.
− Ensure that pressure is relieved
from equipment and connected
accessories.
8.1 Fault finding
Pump does not run:
• No mains voltage.
− Check cables, plug, outlet and
mains fuse.
• Mains voltage too low.
− Use only extension cables with
sufficient lead cross section (see
"Technical Specifications").
• Motor overheated, motor protection
relay tripped.
− After cooling off the pump will
switch ON again.
− Ensure sufficient ventilation, keep
vent slots clear.
− Observe max. temperature of the
pumped medium.
• Motor hums but does not start.
− With the motor switched OFF, put
screwdriver or similar through the
fan cover's vent slots and turn the
fan.
• Pump blocked or out of order.
− Disassemble pump and clean.
− Clean diffusor, replace if neces-
sary.
− Clean impeller, replace if neces-
sary.
Pump does not prime correctly or
runs very noisily:
• Lack of water.
− Ensure there is a sufficient water
supply.
• Suction line leaky.
− Seal suction line, tighten screw
fittings.
• Suction head too high.
− Observe max. suction head.
− Install check valve, fill suction line
with water.
• Suction strainer (accessory)
blocked.
− Clean, replace if necessary.
• Check valve (accessory) blocked.
− Clean, replace if necessary.
• Water leaks between motor and
pump, Duocone seal worn.
− Replace Duocone seal.
• Pump blocked or out of order.
− see above.
Pressure too low:
• Suction line leaky or too much suc-
tion head.
− see above.
• Pump blocked or out of order.
− see above.
A
Danger!
Repairs to electric tools must
only be carried out by a qualified
electrician!
Electric tools in need of repair can be
sent to an authorised service center in
your country. See spare parts list for
address.
Please attach a description of the fault to
the electric tool.
For shipping:
• Drain pump completely (see "Equip-
ment dismounting and storing").
• Ship equipment in original packing,
if possible.
The packaging of the pump can be
100 % recycled.
Worn out power tools and accessories
contain considerable amounts of valua-
ble raw and plastic materials, which can
be recycled.
These instructions are printed on chlo-
