Wilo Stratos Notice De Montage Et De Mise En Service page 71

• Installation outside a building (outdoor installation):
• Install the pump in a sump (e.g. light sump, annular sump) with cover or in a
cabinet/housing as weather protection. Ambient temperatures below -10°C
are not permissible.
• Avoid exposure of the pump to direct sunlight.
• The pump requires protection so that the condensate drain grooves are not
contaminated. (Fig. 6)
• Protection of the pump against rain. Dripping water from above is permitted
provided that the electrical connection has been established in accordance
with the installation and operating instructions and the terminal box has been
properly sealed.
CAUTION! Risk of damage to property!
Ensure sufficient ventilation/heating if the ambient temperature exceeds/
falls below the permitted limit values.
The electronic module can switch off due to excess temperatures.
Never cover the electronic module with any objects. Maintain an adequate
distance of at least 10 cm clear around the electronic module.
• Carry out all welding and soldering work prior to the installation of the pump
CAUTION! Risk of damage to property!
Contamination from the pipe system can destroy the pump during operation.
Before installing the pump, flush the pipe system.
• Provide check valves upstream and downstream of the pump.
• Attach pipework to the floor, ceiling or wall using appropriate fittings so that
the pump does not bear the weight of the pipework.
• When installing in the feed of open systems, the safety supply must branch off
upstream of the pump (DIN EN 12828).
• Remove the two half shells of the thermal insulation (Fig. 5, item 1) before
installing the single pump.
• Install the pump at an easily accessible point so that it can be easily checked or
replaced at a later time.
• Precautions during installation:
• Perform assembly so that the pump shaft is horizontal and not under strain
(see the installation positions shown in Fig. 2a/2b).
• Make sure that it is possible to install the pump with the correct flow direction
(cf. Fig. 2a/2b). Observe the direction triangle on the pump housing (Fig. 1a;
item 2).
• Make sure that it is possible to install the pump in the permitted installation
position (cf. Fig. 2a/2b). If required, turn the motor including control module,
see Chapter 9.1.
CAUTION! Risk of damage to property!
If the module is in a position that is not permitted, there is a risk of water
drips entering the module. The module is not allowed to be positioned with
the cable connection pointing upwards!
