Have maintenance and repair work carried out by qualified special-

It is recommended to have the pump serviced and checked by Salm-
son after-sales service.
DANGER! Risk of fatal injury!
There is risk of fatal injury due to electric shocks when working on
electrical equipment.
• Work on electrical equipment may only be done by electricians
approved by the local electricity supplier.
• Before working on electrical equipment, switch it off and secure it
against being switched on again.
• Follow the installation and operating instructions for the pump,
level control device and other accessories.
DANGER! Risk of scalding!
Due to the high water temperatures or system pressures, there
may be high surface temperatures.
• In the case of high water temperatures and system pressures, allow
the pump to cool down before all work.
• Always wear protective clothing and gloves when working.
NOTE:
For all installation work, the forked spacer (Fig. 13, Item 10) is
urgently required for setting the correct impeller position in the pump
housing!
During the running-in period, a minor amount of dripping is to be
expected. Once in a while, however, a visual inspection is required.
If there is clearly detectable leakage, the seal is to be changed.
• Disconnect the system from the power supply and secure it against
being switched back on again.
• Make sure it is not live,
• Close the check valves in front of and behind the pump,
• Depressurise the pump by opening the bleed valve (Figs. 12, 13, 14;
Item 1.31).
DANGER! Risk of scalding!
Due to high fluid temperatures there is a danger of scalding.
• If the fluid is hot, allow it to cool down before all work.
• Disconnect the module if the cable for dismantling the motor is too
short.
• Release the pressure measuring lines of the differential pressure
sensor.
• Dismantle the coupling protection (Figs. 12, 13, 14; Item 1.32).
• Loosen the coupling screws of the coupling unit (Figs. 12, 13, 14;
Item 1.4).
• Loosen the motor fastening screws (Figs. 12, 13, 14; Item 5) on the
motor flange and lift the drive off the pump with suitable hoisting
gear.
