A
Danger by pump failures!
•
If you notice shipping damage while
unpacking, notify your
immediately. Do not operate the
pump!
•
Before each use check the pump,
especially power cable and plug for
possible damage. Risk of fatal elec-
tric shock!
•
A damaged pump must be work-
manlike repaired before it can be
used again.
•
Do not attempt to repair the equip-
ment yourself! Only trained special-
ists are permitted to service or repair
pumps or pressure vessels.
A
Caution!
To avoid water damage, e.g.
flooded rooms, caused by pump mal-
functions or defects:
•
provide for suitable safety measures
such as the following:
− alarm or
− collection tank with monitoring.
The manufacturer is not liable for any
damage caused by:
− improper use of the pump;
− overloading of the pump through
continous operation;
− failure to operate and store the
pump in a frost-free environment;
− unauthorised modification of the
pump (repairs to electrical equip-
ment may only be carried out by
qualified electricians!);
− use of spare parts which have not
been tested and approved by the
manufacturer; or
− use of unsuitable installation materi-
als (fittings, connection lines etc.).
Suitable installation materials:
− pressure-resistant (min. 10 bar)
− heat-resistant (min. 100°C).

5. Prior to Operation

The pump is easily assembled and con-
nected.
If in doubt, contact your specialist sup-
plier or a qualified electrician.
5.1

Installation

− The equipment must be placed on a
plane and level surface, suitable of
bearing the weight of the equipment
fully filled with water.
− Um Vibrationen zu vermeiden, sollte
das Gerät auf eine elastische Unter-
lage gestellt werden.
− The installation location should be
well vented and protected from
atmospheric exposure.
− When operated at garden ponds
and pools the equipment must be
set up safe against flooding and pro-
supplier
tected from falling into the water.
Any additional legal requirements
are to be observed.
5.2 Connecting the Suction
Line
3
Note:
Possibly further accessories may
be required for connection (see "Availa-
ble Accessories").
A
Caution!
The suction line needs to be
installed in such manner that it does
not exert mechanical force or distor-
tion to the pump.
A
Caution!
When pumping contaminated
fluids install a suction strainer to pro-
tect the pump from sand and dirt.
3
Note:
A check valve is recommended to
prevent water backflow when the pump
is turned off.
− All screw fittings must be sealed
with thread sealing tape; leaks
cause the priming of air, which
reduces or completely prevents the
priming of water.
− The suction line should have an
inner diameter of 1" (25 mm) mini-
mum and must be kink, pressure,
and vacuum resistent.
− 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 Port

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 mechan-
ical 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.
ENGLISH
− 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 per-
sonal injury by liquid spurting from
the line under high pressure!
5.4 Connection to a Pipe
System
A stationary installation (e.g. in an indoor
domestic water system) is also possible.
− To reduce vibrations and noises the
pump should be connected to the
pipe system with flexible tubing.
5.5

Connection to AC Power

B
Danger! Risk of electric shock!
Do not operate the pump in wet
environment and only under the fol-
lowing conditions:
− Connect only to an earthed outlet
that is properly installed, earthed
and tested.
− Mains voltage and fuse protection
must correspond
requirement stated in the "Tech-
nical Specications".
− When operated at pools, garden
ponds and similar locations, the
pump must be protected by a
residual current operated device
(RCD, 30 mA) (DIN VDE 0100 -702,
-738 or equivalent
local regulations).
We recommend the use of RCD's
as a general precaution for per-
sonal protection.
− When operated outdoors the elec-
trical connections
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.
5.6 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.
