ELECTRICAL INSTALLATION
1. Static electricity can cause problems with electrical equipment and operation, ensure that the
equipment is properly grounded during installation.
2. Ground the machine and test its ground resistance, if resistance is less than 5OHM then it is
acceptable. Any auxiliary equipment should be grounded as well.
3. If static is present in bags, the installation of static eliminator may be required. If this feature is
needed, please contact the company for additional information.
INSTALLATION OF AIR SUPPLY (WASHDOWN MODELS ONLY)
If the machine is a washdown model, the machine’s Filter Regulator will be located on the frame of the
PRIMOCOMBI. The PRIMOCOMBI operates at 5PSI (0.3BAR)and has an air consumption of 1CFM (0.03M3/MIN.)
It is important to ensure that the air supply of the owner’s facility can meet these specifications.
To Adjust Air Pressure
1. Pull the knob to release it and adjust
the pressure.
2. If the knob is rotated clockwise, the
inlet pressure will increase, if rotated
counter clockwise it will decrease.
3. Press down on the knob to lock it in
place again once the pressure changes
have been completed.
