Prior To Operation; Installation; Connecting The Suction Line; Discharge Port - Metabo HWW 3000/20 G Operating Instructions Manual

ENGLISH
"Technical Specifications"). Com-
pletely unroll cable reels.

Do not buckle, squeeze, drag or
drive over power cable and exten-
sion cables; protect from sharp
edges.

Place extension cable so that it can
not get into the fluid to be pumped.

Unplug:
 prior to all servicing;
 when persons are in the swim-
ming pool or garden pond.

A
Danger by pump failures!

If you notice transport damage while
unpacking, notify your
immediately. Do not operate the
pump!

Before each use check the pump,
especially the power cable and plug
for possible damage. Risk of fatal
electric shock!

A damaged pump must be work-
manlike repaired before it can be
used again.

Do not attempt to repair the pump
yourself! Only trained specialists 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 pump must be placed on a
plane and level surface, suitable of
bearing the weight of the pump fully
filled with water.
 To avoid vibrations the pump should
be placed on an elastic base.
 The installation location should be
well vented and protected from
atmospheric exposure.
 When operated at garden ponds
and pools the pump must be set up
safe against flooding and safe-
garded against falling into the water.
Any additional legal requirements
are to be observed.
5.2 Connecting the Suction
supplier
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.
Caution! 
A
When pumping contaminated
fluids install a suction strainer to pro-
tect the pump from sand and dirt.
Note: 
3
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 and vacuum
resistent.
 Keep suction line as short as practi-
cal, as with increasing length the
pump capacity is reduced.
 The suction line should ascend
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").
Caution! 
A
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.
Danger! 
A
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

Danger! Risk of electric shock! 
B
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 operating the pump out-
doors the electrical connections
must be splash-proof; the con-
nections must not be placed into
water.
 Use only extension cables of suf-
ficient lead cross section (see
"Technical Specifications"). Com-
pletely unroll cable reels.
5.6 Filling the pump and
priming
Caution! 
A
After installation, loss of water
or priming of air the pump needs to
be filled with water. Starting the pump
without water causes damage!
