Assembly/Disassembly impeller — Internal rotor motor
If an external rotor motor is used, the motor and impeller can`t be seperated.
Important
Damage to the motor and impeller.
The ball bearing of the motor and the balanced impeller may be damaged by forceful impacts.
♦
Attach the impeller and/or the shaft extension to the shaft or the rotor without forceful impacts.
♦
Do not separate the impeller and the hub. They were balanced as one unit by Systemair.
Note:
The hub can be heated for easier assembly and disassembly, for example with a hot-air blower.
• Precondition for assembly: the wedge is in the intended groove.
• Tools: hexagon socket wrench and suitable tool for removal, torque wrench for the taper clamping bush.
