5.2 Scope of supply
 Pump, complete
 Installation and operating instructions
 2 x flat gasket
 Coupling relay
6 Installation and electrical connection
The installation and the electrical connection must be carried out
by specialists and in compliance with the local regulations!
ATTENTION!
WARNING! Risk of personal injury

The terminal box cannot be dismantled. If the regulation module is
separated from the pump by force, there is a risk of personal injury:


During generator operation of the pump (rotor driven by primary
pressure pump), a dangerous voltage occurs on the motor terminals,
which are not protected against access.
ATTENTION!
WARNING! Risk of personal injury

Observe the valid accident prevention regulations.
ATTENTION!
WARNING! Risk of electric shock

It must be ensured that there are no risks resulting from electrical energy.

Instructions resulting from local or general regulations (e.g. IEC, VDE
etc.) and from local utility companies must be observed.
6.1 Installation
 The system/pump must be installed in a dry, well-ventilated
room protected from frost.
 The system/pump must not be installed until all welding and
soldering work is completed; the pipe system must be
flushed if necessary.
ATTENTION!
CAUTION! Risk of material damage

Any impurities in the pipe system can destroy the pump during operation.
Flush the pipe system before the pump is installed.
NOTE
The system must not be purged via the venting screw/unblocking screw
on the front of the pump. The screw can, however, be loosened slightly to
check whether the system is fully purged.
 The installation of shutoff devices upstream and
downstream from the pump is recommended. This means
that it is not necessary to drain and re-fill the system when
the pump is replaced.
 Carry out tension-free installation. The pipes must be
mounted such that the pump does not bear the weight of the
pipes.
 The flow direction of the medium must correspond to the
direction triangle on the pump casing.
 Mounting positions according to Chap. 1 in appendix on
page II only. The pump shaft must be horizontal.
 The pump must be installed in an easily accessible position
to facilitate subsequent service work.
 The pump must be installed such that no water can drip onto
the pump motor and/or the terminal box.
6.1.1 Changing the terminal box position
The motor does not need be completely removed from the pump
casing in order to change the position of the terminal box. The
motor can be rotated into the desired position within the pump
casing, if there is enough space.
Permissible terminal box positions are shown in Chap. 1 in
appendix on page II
ATTENTION!
WARNING! Risk of personal injury

The motor screws can only be loosened and the terminal box position
changed when the system is without pressure/empty.
4 screws must be loosened to release the motor.
ATTENTION!
CAUTION! Risk of damage to the pump

Excessive application of force on the pump terminal box must be
avoided.
ATTENTION!
WARNING! Risk of personal injury

The shaft is inseparably connected to the wheel, the end plate and the
rotor. If the rotor with its strong magnets is not inserted into the motor
casing, there is a high potential for danger e.g. through the sudden
attraction of items made of iron/steel, interference with the operation of
electrical devices (danger to personnel wearing pacemakers), destruction
of magnetic cards etc.
ATTENTION!
WARNING! Risk of personal injury

The terminal box cannot be dismantled. If the terminal box is separated
from the pump by force, there is a risk of personal injury:

During generator operation of the pump (rotor driven by primary
pressure pump), a dangerous voltage occurs on the motor terminals,
which are not protected against access.
