Incorrect installation and electrical connection can result in fatal injury.
• Installation and electrical connection may only be carried out by qualified
personnel and in accordance with the applicable regulations!

9.1

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 possi-
ble 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 horizon-
tal position see Fig. 3 for installation positions of the pump.
• Direction arrows on the pump housing indicate the direction of the flow.

• Disconnect the power supply before any work.
• The current type and voltage must correspond to the details on the name plate.
• Maximum back-up fuse: 10 A, slow bow.

Maintenance

DANGER! Danger of death!
A fatal shock may occur when working on electrical equipment.
• The pump must be electrically isolated and secured against unauthorised
switch-on during any maintenance or repair work.
• Any damage to the connecting cable must always be rectified by a qualified
electrician only.
After successful maintenance and repair work, install and connect the pump ac-
cording to the "Installation and electrical connection" chapter. Switch on the pump
