Guidelines for Compressed Air Systems
7
The air pressure drop between the compressor and
the point of use is not recoverable.
7
Pipe size should be large enough that the pressure
drop does not exceed 10% between the air receiver
and the point of use.
7
Arrange the air distribution piping to avoid the
following types of strain:
7
Strains that are due to dead weight of the pipe itself.
7
Strains that are due to expansion or contraction of the
piping due to temperature.
7
Strains due to internal pressure within the pipe.
7
Design inlet and discharge piping for smooth
airflow.
7
Plan for future emergencies and establish an area of
the loop to install a temporary compressor.
7
Consider a second receiver at the end of the line or
opposite side of the loop.
7
Use loop-piping systems; if possible, both around the
plant and within the loop.
7
Consider a second receiver at the end of the line or
opposite side of the loop.
7
Locate runaways from the main header close to the
point of application.
7
Take air off the top of the header to prevent carryover
of condensed moisture to tools.
7
Slope piping so that it drains toward a drop leg or
moisture trap away from the compressor.
Operation
Every Compressed Air Systems LLC compressor has been
operated and thoroughly tested at the factory prior to
shipment. The test assures that the compressor will
deliver its rated capacity and is in good working order.
However, there is the possibility that damage may occur
in shipping. For this reason, it is recommended that
the unit be carefully inspected for evidence of damage
or malfunction before installation and during the first
hours of operation.
PREPARATION FOR INITIAL START-UP
1. Pull the main disconnect switch and ensure that
there is no power to the unit.
2. Review the installation instructions to see that
everything is complete.
3. Inspect for visible signs of damage that could have
happened during shipment or installation.
4. Make certain protective coverings required for
shipment or painting are removed from the
compressor.
5. Fill the sump to the proper oil level. Do not
overfill, if it is, drain to proper level. Tighten the fill
cap securely.
6. Reconnect the main disconnect.
7. Refer to control section and check out panel
components.
8. “Jog” the motor (press start and stop in quick
succession) and check for the correct direction of
rotation. Reverse LS1 and L2 connections if incorrect
9. Start the unit and run for several minutes, then
shutdown. Check the oil level and add, if
necessary, to compensate for filling the system.
10. Begin normal operation
Reverse rotation will cause air end damage. Exchange leads L1 and L2,
if reverse rotation.
