DISCHARGE SERVICE LINE
- The discharge service line connection is made at the right hand corner of
the package when viewed from the control box end, viewed from the oil cooler side. A hand operated
valve, (air service valve) must be installed between the unit and the customer’s air system. If a fast
operating valve such as a ball valve is used, it must be closed slowly to give the intake valve time to shut
and keep the discharge pressure from spiking. When manifolding two or more rotary screw units on the
same line, each unit is isolated by the check valve in the unit discharge line. If a rotary screw unit is
manifolded to another compressor, be sure the other compressor has a check valve in the line between
the machine and the manifold. If a rotary screw and a reciprocating compressor are manifolded together,
an air receiver must be located between the two units.
DANGER
Discharge air used for breathing will cause severe injury or death.
Consult filtration specialists for additional filtration and treatment equipment to
meet health and safety standards.
ELECTRICAL WIRING
- All of the electrical connections and controls are factory wired for the voltage
specified on the order. Verify that the available voltage source matches that shown on the compressor
package nameplate before installing the compressor package. It is necessary only to connect the
package to the supply and ground of the branch circuit. The connections to the compressor package are
made with the electrical controls box, accessible by opening the cover of the box.
The 24CA4820 Control Transformer (Cutler-Hammer C0250G6U) is connectable for a variety of input
voltages. Ensure that it is properly connected prior to applying power to the package. Recommended
connections are:
