Installation and electrical connection

The installation and the electrical connection must be carried
out by specialists and in compliance with the local regulations!
CAUTION!
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

7.1 Installation

 The system/pump must be installed in a dry, well-venti-
lated 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.
CAUTION!
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.
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.
CAUTION!
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 hexagonal socket screws ( Fig. 1.2 Appendix on page II
item 6) must be loosened in order to release the motor.
CAUTION!
CAUTION! Danger of damage to the pump
Excessive application of force on the pump module must be
avoided.
7.1.2 Insulation of the pump in systems with condensate formation
The pump is suitable for use in refrigerating, air conditioning
and similar systems where the temperature of the medium to
be pumped is as low as -10°C. Condensate can form on me-
dium-bearing components, e.g. pipework or pump casings, if
the ambient temperature is higher than the temperature of the
EN-6
CAUTION!
WARNING! Danger of personal injury!
Observe the valid accident prevention regulations
CAUTION!
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.
 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 Fig. 2.1 Appendix on

page III 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. 6)
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.
CAUTION!
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
destruction of magnetic cards etc.

medium to be pumped. Intermittent pump operation is still per-
missible 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 rele-
vant pump size.
