x
A damaged pump must be work-
manlike repaired before it can be
used again.
x
Do not attempt to repair the equip-
ment yourself! Only trained special-
ists are permitted to service or repair
pumps or pressure vessels.
5. Prior to Operation
The equipment is easily assembled and
connected.
If in doubt, contact your specialist sup-
plier or 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-
tected from falling into the water.
Any additional legal requirements
are to be observed.
5.2 Suction line connection
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 pump from sand and dirt.
3
Note:
A check valve is recommended to
prevent water backflow when the pump
is switched off.
 All screw fittings are to be sealed
with thread sealing tape; leakages
cause priming of air and reduce or
prevent the priming of water.
 The suction line should be of at least
1" (25 mm) inner diameter; it must
be resistent to buckling and vacuum
proof.
 Keep suction line as short as practi-
cal, since with increasing length the
pump capacity is reduced.
 The
suction line
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.
 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 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
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 used outdoors all electri-
cal connections must be of the
splash-proof type; thez must not
be placed in water.
 Use only extension cables of suf-
ficient lead cross section (see
"Technical Specifications").
Unroll cable reels fully.

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.

6. Operation

Pump and suction line must be con-
nected and filled (see "Prior to Opera-
tion").
A
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").
