The blender is equipped with a plug that functions as the disconnect device. The
mating receptacle must be installed no higher than 5’ feet (1.6 m) above the floor.
Make sure your installation conforms to your regional electrical standards.
Power Receptacle Installation
4-6 Pneumatic Installation
The OS/OA blending system uses plant-supplied compressed air to operate the
metering and dump valves on the blender.
CLEAN AND DRY air must be supplied to the blender. The air supply should be
filtered through a 5 micron air filter with a water separator. Oil should not be used
unless air dryers are installed on the compressed air supply. In this situation, an
oiler may be required on the blender to keep the air cylinder seals lubricated.
Important! As this blender uses air for blender metering functions, it is
very important to supply clean, dry air to the blender.
Dirty air
can affect blender accuracy, result in poor performance and
cause injury. Provide a 5-micron air filter on the air supply to
the blender, and be sure excess oil is removed.

AEC/HydReclaim provides all pneumatic lines on the blender piped to a single ¼”
NPT standard pipe thread fitting. The OS/OA blending system requires
approximately 1 cfm (1.7 m³/hr) @ 60 psi (4.14 bar) air pressure for proper
operation.
