Note:
A check valve is recommended to
prevent water backflow when the pump
is switched off.
•
All screw fittings need to be sealed
with thread sealing tape; leakage
places cause the priming of air and
reduce or prevent the priming of
water.
•
The suction line should have at least
1" (25 mm) inner diameter; it must
be non-buckling and vacuum-proof.
•
Keep suction line as short as practi-
cal, since with increasing length the
pump capacity is reduced.
•
The suction line should raise
towards the pump to prevent air
locks.
•
A sufficient water supply must be
ensured, the foot valve at the end of
the suction line must be submerged
in water at all times.
5.3
Discharge hose connec-
tion
3
Note:
Possibly further accessories may
be required for connection (see "Availa-
ble Accessories").
A
Caution!
The discharge (or pressure)
line needs to be installed in such
manner that it does not exert mecha-
nical force or distortion to the pump.
•
All screw fittings should be sealed
with thread sealing tape to prevent
leakage.
•
All parts of the pressure line must be
resistant to internal pressure.
•
All parts of the pressure line must be
installed in a workmanlike manner.
A
Danger!
Improper installation and use
of parts not resistant to internal pres-
sure can cause the pressure line to
break during operation. Risk of perso-
nal injury by liquid spurting from the
line under high pressure!
5.4
Mains connection
B
Danger! Risk of electric shock!
Do not operate the equipment
in wet environment and only under
the following conditions:
•
Connect only to an earthed outlet
that is properly installed, earthed
and tested.
•
Mains voltage and fuse protection
must correspond to those stated
in the "Technical Specications".
•
When operated at pools, garden
ponds and similar locations, the
equipment must be protected by
a residual current operated
device (RCD, 30 mA) (DIN VDE
0100 -702, -738 or equivalent
applicable local regulations).
We recommend the use of RCD's
as a general precaution for per-
sonal protection.
•
When operated outdoors the elec-
trical connections must be
splash-proof; they must not be
placed in water.
•
Use only extension cables of suf-
ficient lead cross section (see
"Technical Specifications").
Unroll cable reels fully.
5.5
Filling the pump and
priming
A
Caution!
After installation, loss of water
or priming of air the pump needs to
be filled with water. Starting the pump
without water causes damage!
3
Note:
The suction line does not need to
be filled, the pump is self-priming. How-
ever, depending on length and diameter
of the suction line it may take some time
until pressure has built up.
1.
Remove the water filler plug, com-
plete with gasket.
2.
Slowly pour in clear water, until the
pump is filled.
3.
To reduce the time needed for prim-
ing you can also fill the suction line.
4.
Replace the water filler plug, com-
plete with gasket.
5.
Open pressure line (open tap or
spray nozzle) for any air to escape
during priming.
6.
Start equipment (see "Operation").
7.
Switch equipment OFF when water
runs out steadily.
Pump and suction line must be con-
nected and filled (see "Prior to Opera-
tion").
A
Caution!
Pump must not run dry. Ensure
there is always sufficient pumping
medium (water) available.
•
If the motor does not start, no pres-
sure is built up or similar effects are
evident, switch the equipment OFF
– and try to remove the fault (see
"Trouble Shooting").
•
If the pump should be blocked by a
foreign object or the motor overheat,
the motor protection will switch the
motor off.
6.1
Commissioning
3
Note:
This pumps runs as long as the
ON/OFF switch is switched ON.
1.
Plug power cable in.
2.
Switch pump on with the ON/OFF
switch.
3.
Open pressure line (open tap or
spray nozzle).
4.
Check to see that the water comes
out!
A
Caution!
With a closed pressure line do
not let pump run for more then
10 minutes, otherwise there could be
damage by the water overheating in
the pump.
6.2
Pump characteristic
curve
The pump characteristic curve shows
which pump capacity is possible in
dependance on the delivery head.
Pump characteristic curve at 0.5 m suc-
tion head and 1" suction hose – for

P 5500 M
A
Danger!
Prior to all servicing:
−
Switch Off.
−
Unplug.
−
Ensure that pressure is relieved
from equipment and connected
accessories.
Repair and maintenance work other
than described here must only be car-
ried out by qualified specialists.
7.1
Periodic maintenance
•
Check equipment and accessories,
especially electrical parts and parts
under pressure for possible dam-
age; have repaired, if necessary.
•
Check suction and pressure lines for
leakages.
