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.
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-
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
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 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
local regulations).
We recommend the use of RCD's
as a general precaution for per-
sonal protection.
When operated outdoors the elec-
raise
trical
splash-proof; they must not be
placed in water.
Use only extension cables of suf-
ficient lead cross section (see
"Technical
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!
1. Remove the water filler plug, com-
plete with gasket.
2. Slowly pour in clear water, until the
pump is filled.
3. Replace the water filler plug, com-
plete with gasket.
4. Open pressure line (open tap or
spray nozzle) for any air to escape
during priming.
5. Start pump (see "Operation").
6. Turn pump OFF when water runs
out steadily.

6. Operation

Pump and suction line must be con-
nected and filled (see "Prior to Opera-
tion").
A
Caution!
The pump must not run dry.
Ensure there is always sufficient pump-
ing medium (water) available.
If the motor does not start, no pres-
sure is built up or similar effects are
evident, switch the pump OFF – and
try to resolve the fault (see "Trouble
with the
Shooting").
