Air Cylinder Lift Operation:
Before connecting your air supply ensure the lift control
valve is in the center (off) position. Connect your air supply
to the quick connector on the 3-position air valve. Maximum
air pressure is 100-PSI. Note that air pressure is used to
both raise and lower the cylinder. The following will enable
you to adjust the height of the impeller or to install and remove
your batch container:
CAUTION:
After the air line is installed and before operating
the machine for the first time, move the lift control valve to
the downward position. This will charge the air cylinder
and prevent surging when the lift control valve is moved to
the upward position.
• Lifting:
Move the lift control valve to the upper most position.
To stop upward motion, move valve to center (off)
position.
• Hold:
To hold the impeller at any height, move the lift control
valve to the center (off) position.
• Lowering:
Move the lift control valve to the lower most position.
To stop downward motion, move valve to center (off)
position.
