7.1 Installation
• Only install the pump after all welding and soldering work has been completed
and, if necessary, the pipe system has been flushed through.
• Install the pump in a readily accessible place for easy inspection and dismantling.
• When installing in the feed of open systems, the safety supply must branch off
upstream of the pump (DIN EN 12828).
• Install check valves upstream and downstream of the pump to facilitate a possible
pump replacement.
• Perform installation so that any leaking water cannot drip onto the control
module,
• To do this, aline the upper gate valve laterally.
• In thermal insulation work, make sure that the pump motor and the module are
not insulated. The condensate-drain openings must remain uncovered.
• Install the pump with the power switched off and the pump motor in a horizontal
position see fig. 4 for installation positions of the pump.
• Direction arrows on the pump housing indicate the direction of the flow.
