Exhaust Blower/Motor Replacement - Labconco Logic Vue User Manual

Exhaust Blower/Motor Replacement

1. Disconnect electrical power from the enclosure. Remove the Lower Front Service
Panel by rotating each of the four (4) Panel Latches 90 degrees with a flatblade
screwdriver. Reference Figure 11-12.
2. Locate the two (2) Wire Harness connections on the inner side of the Exhaust
Blower's motor. Note: the entry of wires to the motor is difficult to see and reach.
Trace the wire harness from the motor approximately 12 inches (300 mm).
Another set of two Connectors will be located here. On these two Connectors,
depress the latch on each connector and pull the connectors apart. The short
"tail" wire harness will remain connected to the motor. This short tail harness is
provided because access to the motor wire connections is difficult.
3. Remove the five (5) Bolts securing the Exhaust Blower/Motor assembly. Note
that one Bolt is on the far side of the Blower.
4. Rotate the discharge end of the Blower towards you about 10 degrees, then slide
the Blower towards you. Using a 5/16" Wrench, remove the two Blower
Connection Plates (one on each side of the Blower).
5. Move the short "tail" wire harness and the Blower Connection Plates to the new
Exhaust Blower/Motor and replace all parts in reverse order.
