Installing A Threaded Pipe Union Pump - Wilo Stratos Betriebsanleitung

English
• 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.
• 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.
• 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.

7.1.1 Installing a threaded pipe union pump

• Install appropriate threaded pipe unions before installing the pump.
• Use the supplied flat gaskets between the suction/pressure ports and threaded
pipe unions when installing the pump.
• Screw union nuts onto the threads of the suction/pressure ports and tighten
them using a suitable open-end wrench or pipe wrench.
