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
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.
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.
ATTENTION!
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.
Tension-free installation. The pipes must be mounted in
such a way 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 page II
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. (Chapt. 7.1.1 on page 5 )
The pump must be installed in an easily accessible position
in order to facilitate subsequent service work.
The pump must be installed in such a way 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.
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.
Four M6 hexagonal socket screws (Fig. 1.1 Appendix page II
item 6) must be loosened in order to rotate 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 degree of 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
7.1.2 Insulation of the pump in systems with condensate formation
The Wilo-Stratos PARA 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 medium to be pumped. Intermittent pump
operation is still permissible even in these cases.
Diffusion-proof insulation must be provided on site when the
pump is used in these system types.
With pumps with P1 max <= 72 W, the special motor design
means that no condensate can form inside the motor.
The pump casing is cataphoresis-coated to protect it from
corrosion.
