4.8 DIRECTION OF ROTATION
Once the control circuit has been checked, all piping installed, and compressors is filled with lubricoolant,
push the ‘run’ key (green) and observe the direction of rotation. If rotation direction is incorrect, push the
emergency stop button. Change two motor leads if rotation is incorrect. Incorrect rotation is only possible
if the motor was disconnected.
4.9 COMPRESSED AIR PIPING
Connect the compressor to the plant air system with a flexible connector rated for at least 200 psi (1380
kPa) and 275° F (135° C). Support the piping to insure that no pipe stress is transmitted to any
compressor component.
Compressor should be piped into a receiver tank prior to any filters or dryer. A moisture separator may
be placed between the compressor and receiver tank.
Piping should be as large as possible to minimize transmission losses. Piping should be in a “closed
loop” configuration, sloping to drain points, with service air outlets taken from the side or, preferably, the
top of the pipe. Point-of-use filters, coalescers, regulators and/or lubricators are often required. (Note:
Never use plastic air piping or plastic bowls on filters or lubricators. See Section 1.) Inspect piping and air
hoses frequently for leaks.
4.10 ADDITIONAL HELP
By making the cleanest, coolest air available to the compressor inlet, maintenance and power
consumption will be minimized. The standard air filter is locally mounted. For a remote inlet an optional
filter must be fitted.
When connecting to a remote air inlet, use a flexible connector at the filter inlet. Keep the piping as short
and as straight as possible. Intake duct must be the same size as filter inlet, or larger, to accommodate
long runs and several bends creating no restrictions to air flow.
Support intake ducting properly to prevent its weight being transmitted to the compressor air filter.
For multiple machine installation, contact the factory for special sequencing controls that can reduce
power cost during part-load operation.
Fan air ducted outside will reduce the machine noise somewhat, but care must be taken not to impose
additional restriction to the fan air flow. With proper attention to the ducting, this fan air can also be
utilized for heating purposes.
