WARNING
The controller has an automatic start/stop sequence built in. You DO NOT need
to close the air service valve. Closing the air service valve on start-up or prior
to shutdown will cause rapid cycling, and could cause a high pressure
shutdown.
When piping two or more rotary screw units on the same line, each unit is isolated by the minimum
pressure/check valve mounted on each compressor package.
If a rotary screw unit is piped 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 piped 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 control box, accessible by opening the cover of the box.
Perform all wiring in accordance with the National Electrical Code (NFPA-70) and any applicable local
electrical codes. Wiring must be performed only by qualified electricians.
WARNING
Electrical shock can cause injury or death. Open main disconnect switch,
lockout and tagout before working on control box.
If the optional base mounted air receiver and/or dryer is on this package, 110 volt single phase power will
need to be supplied to the optional dryer and to the moisture drain on the air receiver.
GROUNDING - Equipment must be grounded in accordance with Section 250 of the National Electrical
Code.
