V-Line Blower
How to Clean
For models starting with K250.

Step 1. Release the blower pan.
Be sure the motor is turned off before proceeding. The blower pan is easily removed for
cleaning by unsnapping the suitcase latches (one on each side of the blower assembly).

Step 2. Remove the blower pan.
With the blower pan latches released, remove the blower pan by pulling the pan downward.
Be careful to keep the tray level if the hood has been recently used.

Step 3. Release the blower wheel.
The blower wheel can be removed by using a 1/8” hex wrench. There is a small set screw
on the side of the hub in the base of the wheel that tightens up against a “at” spot on the
motor shaft. There is also a small hole in one of the blades of the blower wheel that aligns
with the set screw. Insert the wrench through the hole in the fan blade and into the set
screw. The set screw must be turned 1/2 turn counterclockwise to free the blower wheel
from the motor shaft. If the hood is more than ve years old and the set screw has never
been loosened, it may be difcult or even impossible to remove the blower wheel. A liquid
penetrating oil may help you loosen the set screw, but it might prove more practical to clean
the wheel without removing it from the motor shaft.

Step 4. Remove the blower wheel.
Once the set screw is loosened, pull the blower wheel downward slightly, then gently remove
the blower wheel from shaft. Use caution to avoid bending or distorting the blower wheel
and take care not to move or lose the metal balancing clips that may be afxed to the blower
wheel. If the blower wheel is difcult to remove, the area where the motor shaft makes
contact with the blower wheel hub may need to be sprayed with a common penetrating oil
such as WD-40®and allowed to soak for a short time.

Step 5. Clean the parts and reassemble.
The inside of the blower assembly that remains inside the hood can be
cleaned with a soft cloth and warm soapy water (liquid dish detergent).
Do not use acids, abrasives, strong detergents, solvents, or scouring
pads. When cleaning interior blower surfaces, be careful to avoid any
metal edges.
Clean the blower pan in a sink of warm soapy water (liquid dish detergent)
and let soak for a few minutes. Wash with a sponge or dishcloth, rinse,
and let drain.
A soft bristle toothbrush with warm soapy water may be used to clean
the blades on the blower wheel. Alternatively, the blower wheel may be
soaked in warm soapy water.
Reassemble in the opposite order of disassembly. When reinstalling
the blower wheel onto the motor shaft, make sure the set screw makes
direct contact with the “at spot” on the motor shaft. Slide the blower
wheel onto the motor shaft as far as it will go, making sure the top of
the blower wheel does not touch the upper scroll area.
If the blower wheel is too far up, it will rub against the upper scroll area,
and if it is too far down, it will rub the inside of the blower pan. Adjust
the blower wheel slightly to nd the correct top-to-bottom location.
Tighten the set screw (clockwise) to lock the blower wheel in the correct
position.
Once it’s had time to completely dry, reinstall the blower pan and snap
it in place via the suitcase latches (one on each side of the blower
assembly).
