WARNING
Risk of scalding from hot fluids!
Hot fluids can cause scalding.
Before the installation or removal of the pump or the dismantling of the
housing screws, observe the following:
• Allow the drinking water system to cool down completely.
• Close shut-off valves or drain the drinking water system.
CAUTION
An incorrect installation position may damage the pump!
• Select the installation site according to the permitted installation posi-
tion (Fig. 2).
• The motor must always be installed horizontally.
• The electrical connection must never face upwards.
•
Choose an installation point that is easily accessible.
•
Observe the pump's permitted installation position (Fig. 2), rotate the motor head (2 + 6)
if necessary.
•
Install shut-off valves upstream and downstream of the pump to facilitate pump replace-
ment.
CAUTION
Leaking water may damage the control module!
Align the upper shut-off valve on the side so that leaking water cannot
drip onto the control module (6).
•
Provide non-return valves.
•
Complete all welding and soldering processes.
•
Flush the pipeline system.
WARNING
Risk of fatal injury from magnetic field!
Highly magnetic components are fitted inside the pump; they can cause
fatal injury to people with medical implants if the pump is dismantled.
• Never remove the rotor.
Rotate the motor head (Fig. 3) before installing and connecting the pump.
•
If necessary, remove the thermal insulation shell.
•
Hold the motor head (2+6) and unscrew the 4 housing screws (5).
CAUTION
Damage to the inner gasket causes leakage!
Carefully rotate the motor head without removing it from the pump hous-
ing.
•
Carefully rotate the motor head (2+6).
•
Observe the permitted installation position (Fig. 2) and the direction of flow arrow on the
