INSTALLATION
AIR SUPPLY
The reject mechanism is operated by an air supply. The connection
for air is located externally on the right hand side of the unit. A
quick release coupling is provided for connecting an air pipe of 1/4
NPT threads to the unit.
An air regulator is located on the reject valve assembly, mounted
on a bracket. A minimum pressure of 90 psi (6.2 bar) is required
from the incoming air supply, up to a maximum of 150 psi (10 bar).
The output pressure from the air regulator is preset in the factory to
supply 80 psi (5.5 bar). Check the regulator’s gauge. If the
pressure gauge is displaying an incorrect pressure level then it
should be adjusted. The air pressure must be set between 70 and
80 PSI to properly reject metal.
To do this, lift the regulators adjustment dial and turn it clockwise to
increase the pressure or counterclockwise to reduce the pressure.
Regularly activate the drain valve to release any moisture that may
have accumulated in the regulator.
PIPE CONNECTIONS
All pipe connections use Jacobs fittings.
All piping must be secured for proper operation of the equipment.
When the diverter flap is operating there is a danger of crushing injuries. With pipe sizes
larger than 3.15 inches (80mm) it is possible to reach into the diverter mechanism from
the openings. The installation arrangement must prevent any possibility of reaching into
the diverter mechanism.

WARNING
• The pressure applied to the system must not exceed 150 psi (10 bar).
• Do not block drain valve located at the bottom of the air regulator.
• The maximum operating temperature of the air regulator must not exceed 125 F.
