3.3 Compressed air requirements
The MV-loader uses compressed air to create vacuum. The compressed air source must deliver a
maximum of 58-116 PSI {4-8 bar} of clean, dry (non-lubricated), air pressure.
 Make connections from the solenoid and the ejector pipe with the provided compressed air
tubing. Quick disconnect fittings are provided for these connections. The tubing should be cut
to length for maximum efficiency of the system. Use straight cuts to assure a good square
tubing end. Ensure everything is connected firmly.
CAUTION:
Be sure to provide hazard-free routing of the tubing, keep it away from hot or moving surfaces and
out of the way of personnel.
3.4 Air wand adjustment
The air wand can be adjusted in three different positions, which position is required depends on the
properties of the material to conveyed. The adjustment of the wand regulates the mixture of
conveying air and material to be conveyed.
Position 1: Standard position
Position 2: Additional conveying air
Position 3: Maximum conveying air
Conair recommends starting with Position 1.
If there is no or minimal material conveying, the air wand can be adjusted to Position 2. The larger the
granule, the less extra air is needed for conveying.
When Position 2 or 3 is used when Position 1 is sufficient, it can result in poor operation:
- Reduced capacity
- More frequent filter clogging.
