The mini filter-regulator assembly consists of one mini air filter and two mini air regulators. Each mini filter-regulator assembly is furnished with 25’
of 5⁄32” air tubing (PVC). This mini filter-regulator assembly is used to adjust the air pressure for the air cylinder inside the drop-probe assembly.

INSTALLING THE MINI FILTER-REGULATOR
ASSEMBLY
1. Drill and tap holes on the machine where the mini filter-regulator
assembly is to be located (within 2 feet of the control box). Be careful
when drilling holes into the frame of the machine. Avoid internal
components that could affect machine operation.
2. Place one bolt and two 1⁄4” flat washers (not furnished) to each of
the four mounting feet on the mini filter-regulator assembly. These
washers provide the necessary spacing for the tubing connectors on
the back of the assembly. (See photo at right.)
3. Measure, cut, and connect two lengths of 5⁄32” air tubing from the
mini filter-regulator assembly to the air tube bulkheads on the outside
of the control box. Make sure the air tube from the left side regulator
is attached to the left air tube bulkhead.
4. Secure the mini filter-regulator assembly to the machine.
