7 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! Danger of personal injury
The regulation module cannot be dismantled. If the regulation module
has been separated from the pump by force, there is danger of personal
injury:
When the pump is in generator operation (with the rotor driven by the
booster pump) a dangerous voltage is present at the motor terminals
which are not protected against accidental contact.
Due to the remaining electrical connection on the regulation module

WARNING! Danger of personal injury!
Observe the valid accident prevention regulations.
ATTENTION!
!!
WARNING! Danger 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.
7.1 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! Danger of damage to property!
Any impurities in the pipe system can destroy the pump during operation.
Flush the pipe system before the pump is installed.
The installation of shutoff devices upstream and down-
stream 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 di-
rection triangle on the pump casing.
Mounting positions according to Abb 1.1 Anhang Seite II
only. The pump shaft must be horizontal.
Under special installation conditions, the motor can be ro-
tated to bring the regulation module into a horizontal posi-
tion. (Kap. 7.1.1 auf S. 7)
The pump must be installed in an easily accessible position
in order 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.
7.1.1 Module position changes
The motor does not need be completely removed from the pump
casing in order to change the position of the regulation module.
The motor can be rotated into the desired position within the
pump casing, if there is enough space. (Kap. 1 auf S. II)
ATTENTION!
!!
In the event of condensate formation and during cooling applications, the
electrical connection must always be on the right-hand side of the pump
body (“3 o'clock” position).
ATTENTION!
!!
WARNING! Danger of personal injury
The motor screws can only be loosened and the module position
changed when the system is without pressure/empty.
4 M6 hexagon socket screws must be loosened to release the
motor.
ATTENTION!
!!
CAUTION! Danger of damage to the pump
Excessive application of force on the pump module must be avoided.
ATTENTION!
!!
WARNING! Danger 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.

7.1.2 Insulation of the pump in systems with condensate formation
The UP series is suitable for use in refrigerating, air conditioning
and similar systems where the temperature of the medium to be
pumped is as low as 2 °C. Condensate can form on medium-
bearing components, e.g. pipework or pump casings, if the ambi-
ent temperature is higher than the temperature of the medium to
be pumped. Intermittent pump operation is still permissible even
in these cases.
For use in systems like these, a diffusion-tight insulation must be
fitted on-site or a cold insulation shell suitable for the relevant
pump size.
