Replacing the Wash Arms
The wash arms are responsible for distributing the water throughout
the tank and ‘scrubbing’ the glassware clean. If they become
deteriorated or clogged or need to be replaced for any other reason,
follow the instructions below for their replacement.
**Completely drain and disconnect electrical power to the unit before
proceeding with any of these instructions.
1. Open the door and remove any racks that are inside the tank of the
washer.
2. Each wash arm has four corner screws holding the assembly in place.
3. Remove these screws to pull free the Wash Arm Assembly.
4. Place the replacement assembly over the corresponding distribution
outlet.
5. Secure the assembly to the distribution manifold with the four screws.
NOTE: Also use this procedure for replacing the wash arm assembly found on
the Upper Basket and Spindle Racks.
Replacing the Detergent Cup
The Detergent Cup is operated by a wax motor that is signaled by the
PC Board and is slowly reset. In the FlaskScrubber® and the
FlaskScrubber® Vantage®, the spindles on the lower rack in front of
the Detergent Cup must be short spindles; long spindles will not allow
the Cup’s door to open fully, and the detergent will crust and
solidify in the cup, potentially causing damage over time as well as
not cleaning the lab ware. It will also prevent optimal cleaning of
the labware. Use the procedure below to replace the Detergent Cup.
