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

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
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.
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.
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 hexagonal socket screws ( Fig. 1.2 Appendix on page III
item 6) must be loosened in order to release the motor.
ATTENTION!
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 UPE 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 -10°C. Condensate can form
on medium-bearing components, e.g. pipework or pump casings,
if the ambient temperature is higher than the temperature of the
EN-6
devices upstream and
452115.66.38 FD 9601
ATTENTION!
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.
 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 IV only. The pump shaft must be horizontal.
Under special installation conditions, the motor can be
rotated to bring the regulation module into a horizontal
position. (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.
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.
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
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.
