1.2 Brief description
Fresh air flows through the underside of the
enclosure, is filtered by air filter and enters into
the airend for compression process. The
compressed air is released via outlet of airend
and enters into the aftercooler for cooling.

For detailed information about the
controller installed, consult the sepa-
rate  Controller documentation.

Fig. 8 ： Belt and belt pulley
The airend of compressor is driven by main
engine via belt pulley (Fig 8). The rotating speed
of airend of compressor is constant. There was
no Inverter type.
Note: There is different of belt pulley of motor
side between 50/60Hz.
1.3.4 Air filter
ES04
ES08~ES15
Fig. 9 ： Air filter
Air filter of scroll compressor (Fig 9) is located at the
inlet of the airend. The sucked-in air flows directly
into the airend for the purposes of compression.

outlet after the air being compressed.Both inlet and
outlet are at the back of the airend.
1.3.6 Safety valve

The major purpose of the safety valve
(ES04

Fig. 12：Non-return vavle
The non-return valve (
ES04

network to the compressor airend in the event of
machine stoppage,whitch could otherwise cause
reverse operation and/or leaks.

The compressed air that flows through the cooler
is cooled by the cooling-air
fan( ES04
ES08~ES15
Fig. 14). The inner air of enclosue is sucked out by
the cooling-air fan to keep the inner air tempera-
ture to be constant.
You can find information on cooling air volumes in
the “Technical Data” chapter.
Ventilation in the air compressor
room shall consider providing
sufficient space for discharging
compressed air and hot air .The
discharged air can be used for heat
recovery system.

A portion is sucked through the air filter and com-
pressed by the airend. The remaining air flows

2.2 Proper use
The machine is designed and constructed exclu-
sively for the proper use described here.
The scroll compressor is only intended to generate
compressed air in a non-explosive environment
and must be supplied with cool, dry and dust-free
cooling air. It is designed for 2,500 operating hours
per year and wouldn’t be the continued running
machine.
Do not operate the compressor in excess of its
rated pressures and speeds indicated on the
compressor nameplate.
The proper use also includes compliance with all
details in this manual.
Any use above and beyond the proper use, or any
other type of use, is considered misuse.
WARNING!
Danger due to misuse!
- The compressed air may not be
used for respiration purposes
without prior after-treatment.
- The compressed air may not be
used directly for pharmaceutical or
health treatment purposes, or for
direct treatment of food without
appropriate after-treatment.
- The scoll compressor may not be
operated outdoors.
- The scroll compressor or its
individual components may not be
converted, modified or retooled.
- The scroll compressor may not be
used in an potentially explosive
atmosphere.
- The intake of any media other than
cool, dry and dust-free cooling air is
forbidden.
No Claims of any kind can be asserted for damage
resulting from misuse.

2.3 General safety
1. Read and understand all the instructions found
in this manual before operating your compres-
sor.
2. Disconnect the main power source before
working on or performing any maintenance
procedures on this unit. Use a lock out and
tag out process.
3. Do not attempt to remove any parts, break any
connection, loosen oil fill plug or drain plug until
the unit has been shut down and air pressure
has been relieved.
4. Do not operate the compressor in excess of its
rated pressures and speeds indicated on the
compressor nameplate.
5. Do not remove guards, shields, or screens
while the compressor is in operation. If re-
moved for maintenance replace before resum-
ing operation.
6. Observe the delivery pressure gauge daily to
be sure the automatic control system is oper-
ating within proper limits.
7. Periodically check all safety and relief devices
for proper operation.
8. Use compressed air properly. Pressurized air
can cause serious injury to personnel.
9. Be sure that no tools, rags or loose parts are
left in or on the compressor or drive parts.
10. Do not use flammable solvents for cleaning
parts.
11. Exercise cleanliness during maintenance and
when making repairs. Keep dirt away from
parts and exposed openings by covering with
clean cloth or Kraft paper.
12. Do not install a shut-off valve in the discharge
line without installing a pressure relief valve
between the shut-off and the compressor
package.
13. Do not operate the compressor in areas where
there is a possibility of flammable or toxic sub-
stances entering the system.
14. Never disconnect (or jump) the air discharge
temperature switch or any other safety device
and attempt to operate the compressor.
15. Know what mode of operation the compressor
is in before working around the unit. The power
may be on but the machine not running if it is in
the auto restart mode. Adhere to note #2
above.
2.4 Safety devices
WARNING!
Risk of fatal injury from
non-functional safety devices!
Risk of serious or fatal injury from
