Replacing the Blower
Each of Labconco’s glassware washers has an integrated blower for
drying glassware at the end of a cycle. The SteamScrubber’s® blower
pushes air into the tank through the blower shroud (found in the rear
left of the tank). The FlaskScrubber® uses the water manifold of the
washer to circulate hot air that is directly injected into narrow neck
glassware. The FlaskScrubber® Vantage® models use the same blower set
up as the FlaskScrubber®; however, the air fed to the blower is pulled
through a HEPA filter before being circulated through the tank. Use
the procedure below to replace the blower of the unit you are working
on.
**Completely drain and disconnect electrical power to the unit before
proceeding with any of these instructions.

weldment. The coupler from the blower into the blower shroud is not sealed
and once disconnected can be freed by pulling down on the blower/coupler.
1. Pull the unit away from walls/cabinets so that you have access to the
back and left sides of the washer.
2. Remove the back and left cosmetic panels or service access panels and
pull up the black insulation jacket and secure it.
3. Locate the Blower mounted on the back left corner post of the base
weldment.
4. Remove the two screws securing the blower to the corner post.
5. Firmly, grasp the blower’s coupler (connecting the blower to the
blower shroud in the tank) and pull down to free it from the tank.
6. Remove the electrical connections to the blower.
7. Reconnect the wires to the new Blower
8. Reseat the new blower’s coupler into the blower shroud in the tank
through the bottom.
9. Using the original hardware, secure the blower to the corner post.
10. Test the unit blower in diagnostics.
