• Before reinstalling the electronic module, pull the new O-ring
between the electronic module (Fig. 7, Item 22) and the motor (Fig. 7,
Item 4) onto the contacting chamber.
• Press the electronic module into the contacting of the new motor and
fasten with screws (Fig. 7, Item 21).
NOTE:
The electronic module has to be pressed on as far as possible when it
is installed.
• Carry out steps 20 to 40 to install the drive in accordance with chapter
10.2 "Maintenance work" on page 113.
DANGER! Risk of fatal injury!
There is a risk of fatal injury from electric shock when working on
electrical equipment. Following removal of the electronic module, a
potentially fatal shock voltage may be present at the motor contacts.
• Check for absence of voltage and cover or cordon off adjacent
live parts.
• Close the shut-off device upstream and downstream of the pump.
NOTE:
Increased bearing noises and unusual vibrations indicate bearing
wear. Then the bearing has to be changed by Salmson customer serv-
ice.
WARNING! Risk of injury!
Opening the motor leads to high, suddenly occurring magnetic
forces. These can cause serious cuts, crushing injuries and bruises.
• Do not open the motor!
• Only allow Salmson customer service to dismantle and install the
motor flange and the bearing plate for maintenance and repair
work.
NOTE:
The magnets inside the motor pose no risk to persons with pacemak-
ers provided that the motor is not opened and the rotor is not
removed. The electronic module can be replaced without any risk.
DANGER! Risk of fatal injury!
If the rotor is driven by the impeller when the pump is in standstill,
dangerous contact voltage can arise at the motor contacts.
• Close the shut-off device upstream and downstream of the pump.
• Carry out steps 1 to 7 to dismantle the electronic module in accord-
ance with chapter 10.2 "Maintenance work" on page 113.
• Remove the screws (Fig. 7, Item 21) and pull the electronic module
from the motor.
• Replace the O-ring.
• Proceed further (restore pump to operational standby) as described in
chapter 10.2 "Maintenance work" on page 113 in reverse order
(steps 5 to 1).
NOTE:
The electronic module has to be pressed on as far as possible when it
is installed.
NOTE:
Observe the measures for commissioning (chapter 9 "Commission-
ing" on page 108).
Carry out steps 1 to 7 to dismantle the fan wheel in accordance with
chapter 10.2 "Maintenance work" on page 113.
• Lever the fan wheel down from the motor shaft with a suitable tool.
• For the installation of the new fan wheel, pay attention to the correct
bearing of the tolerance ring in the hub groove.
