Installation Of A Threaded Pipe Union Pump - Wilo TOP-Z Serie Instrucciones De Instalación Y Funcionamiento

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).
• If necessary, remove the two half shells of the thermal insulation before install-
ing the single pump.
• Install the pump at an easily accessible location to allow it to be easily checked
or replaced at a later time.
• Precautions during installation:
• Perform assembly such that the pump shafts are horizontal and not under
strain (see the installation positions shown in fig. 2). The motor terminal box
should not face downwards; if necessary, slacken the internal hexagon screws
and rotate the motor housing (see chapter 9).
• The direction of flow of the fluid must correspond to the direction of flow
symbol on the pump housing or the pump flange.

7.1.1 Installation of 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.
CAUTION! Risk of damage to property!
When tightening the screwed connections, keep the pump in position by
gripping the motor. Not the module/terminal box!
• Check the threaded pipe unions for leaks.
• Single pump:
Fit the two half-shells of the thermal insulation before commissioning and push
them together so that the guide pins engage in the opposite holes.
