completely of water. For this purpose, the water level must
be lowered below the level of the inlet openings in the
swimming pool, and the preliminary filter cover then opened
by hand. To protect the pump against frost, the preliminary
filter cover must be emptied via the two drain plugs. Then
clean the preliminary filter housing of the pump, refit the
preliminary filter cover and screw it shut (5MPR).
Screw the preliminary filter cover shut by
hand only (5MPR)!
If the pump is to remain outdoors over the winter months,
the complete system should be properly covered with plas-
tic sheeting. Adequate ventilation must also be ensured to
prevent the formation of condensation. If the pump can be
removed from the system, it should be stored over the win-
ter in a dry area (e.g. garage or heating room).
Store the pumps so that they are protected against damage.
Check all water pipe connections when re-installing the
pumps after the winter. Open the shut-off valves in the suc-
tion and pressure lines. Close all drain valves in the system
and on the pump. Start the pump in accordance with the in-
structions given in Chapter 5 "Installation and commissio-
ning".
Proceed in the same way after extended periods of non-
use.
5. Installation and
commissioning
This section describes the procedure for the installation
and commissioning of the pumps. It describes how the work
must be carried out, and features requiring special atten-
tion.
The installation and commissioning of the
pumps may be carried out only
by suitably qualified personnel.
The swimming pool must be equipped with
bottom outlets suitably protected against sucking
in any foreign bodies (anti-vortex). Otherwise,
2 bottom outlets must be installed.

5.1 Initial installation

The place of installation must have a firm, level
and vibration-free undersurface.
The pump should preferably be installed on a concrete sur-
face, and screwed in place using the holes in the base of
the pump. The pump must be installed in a dry location. If
the pump is installed in a damp location, adequate ventila-
tion must be ensured to prevent the formation of condensa-
tion. Adequate ventilation must always be ensured in case
of installation in shafts.
Shut-off valves must be installed in the inlet and
outlet lines of the pump.
A drain must be provided to dispose of any water.
Sufficient space must be allowed for the installation and
maintenance of the pump. Note the pump dimensions, and
allow at least 25 cm free space at the end of the motor for
adequate motor ventilation and dismantling of the motor
unit.
The pump should be installed as close as possible to the
pool.
Short, straight pipes should be used wherever possible to
avoid friction losses.
5.1.1 Installation below the water level
The pump can be installed at a maximum of 3 m below the
water level. The pump does not need to be filled with water,
since there is a continuous water supply. It must however
be possible to ventilate the pump housing and suction line,
so that the pump fills with water, and cannot run dry.
5.1.2 Installation above the water level (5MPR)
When installing the pump above the water level, a foot valve
should be installed if the installation point is up to a maxi-
mum of 2.5 m above the suction line. The suction performan-
ce will be significantly reduced if the suction distance is too
far or the pipe diameter too small. The suction line must be
sealed, and as short as possible.
5.1.3 Lighting
The Installation and commissioning, and all other work on
the pumps should only be carried out in an environment
where adequate lighting is available.

5.1.4 Noise level

The maximum continuous noise level generated by the
pumps is given in the Chapter "Technical data".
A higher noise level may be generated, depending on local
conditions, which can cause noise deafness. In this case,
operating personnel must be provided with suitable perso-
nal protection equipment.
