as outlined in the manual to ensure problem free operation after start up.
SAFETY AND PRECAUTIONS
BEFORE INSTALLING THE COMPRESSOR OR PERFORMING
ANY MAINTENANCE READ THIS MANUAL CAREFULLY.
WARNINGS
COMPRESSED AIR AND ELECTRICITY ARE DANGEROUS. BEFORE DOING ANY WORK ON THIS UNIT, BE SURE THE
ELECTRICAL SUPPLY HAS BEEN SHUT OFF(LOCKED AND TAGGED) AND THE ENTIRE COMPRESSOR SYSTEM HAS
BEEN VENTED OF ALL PRESSURE.
1. Do not remove the cover, loosen or remove any fittings, connections or devices when this unit is operating or
in operation. Hot liquid and air that are contained within this unit under pressure can cause severe injury or
death.
2. The compressor has high and dangerous voltage in the motor, the starter and control box. All installations
must be in accordance with recognized electrical procedure. Before working on the electrical system, ensure
that the system's power has been shut off by use of a manual disconnect switch. A circuit breaker or fuse
switch must be provided in the electrical supply line to be connected to the compressor. The preparation work
for installation of this unit must be done on suitable ground, maintenance clearance and lightning arrestors
for all electrical components.
3. Do not operate the compressor at a higher discharge pressure than those specified on the compressor
nameplate. If so an overload will occur. This condition will result in electric motor compressor shutdown.
4. Use only safety solvent for cleaning the compressor and auxiliary equipment.
5. Install a manual shut off valve(isolation type) in the discharge line for service work.
6. Whenever pressure is released through the safety valve during operation, it is due to excessive pressure in the
system. The cause of excessive pressure should be checked and immediately corrected.
7. Before doing any mechanical work on the compressor,
a) Shut down the unit.
b) Electrically isolate the compressor by use of the manual disconnect switch in the power line to the unit.
Lock and tag the switch so that it cannot be operated.
c) Release all compressed air within the system and isolate the unit from any other sources of air.
8. Allowing the unit lubricants to enter into the plant air system must be avoided at all times. Air line separators,
which are properly selected and installed, can reduce any liquid carry-over close to zero.
9. Before starting the compressor, the maintenance instructions should be thoroughly read and understood.
10. After maintenance work is completed, covers must be securely closed.
11. For questions contact your distributor before proceeding.

3.3 Installation
3.3.1 Installation Precautions
Our compressor is for indoor use. Sufficient amount of room where it is easy to inspect and maintain
the machine is needed.
Please select installation location considering below conditions.
1)
make sure the location has good air circulation with low temperature and humidity.
• Surrounding temperature must not rise above 104°F(40°C.)
• Ventilation fan must be installed in locations with low ventilation.
2)
Please choose a location with less dust.
3)
Please choose locations with no toxic gas.
4)
Space needed for inspection and maintenance must be secured.
• For disassembled inspection for compressor, secure enough space as shown in <Fig. 5>.
5)
This product has weak vibration. Therefore, it may not create negative effect in the surrounding.
However, the ground solidity must be strong enough to endure total weight of the machine.
6)
Please make sure the range of voltage change is within 10%.
7)
If the noise created is reflected on the wall, the noise may increase compared to the noise
of normal operation.
<Fig. 5>

COAIRE, Div. of Quietside Corporation
3.5 Piping
When installing the pipe of compressed air, make sure less bindings, connections or valve are used for
the minimum compression loss as possible. Greater loss of compression causes higher setting of
discharge compression of the compressor, thus causing loss of power. Also, when there is an area that
is lower than the other in piping, moisture may accumulate thus increasing the pipe resistance. Also,
pipe may explode due to freezing in the winter. Therefore, please consider the moisture management
sufficiently enough prior to pipe installation.
Precautions
1.
Make sure the length of the pipe is as short as possible for less loss of pipe compression
and please reduce the number of connecting joints such as valve, elbow.
2.
Please install drain plug in the lower area of the pipe.
3.
Please install bypass pipe on the compressor to facilitate maintenance.
4.
There is a check valve installed inside the compressor. Do not install separate check valve in
the pipe. When installed, there can be an error in load-unload transformation.
5.
When connecting the compressor exit to the pipe, connect with rubber hose
so the compressor vibration is not transferred to the pipe.
6.
In case of stopping the operation frequently, it is desirable to install separate tank.
3.6 Wiring
1)
Wiring is already completed inside the compressor. Just connect the power adaptor to
complete wiring.
2)
Please use terminal when connecting power adaptor.
3)
Power circuit breaker must be installed and short circuit must be protected through
short- circuit breaker.
4)
Please open the front control panel.
5)
Insert power cable through the power cable hole (rubber attachment) on the right surface
to connect to electric connector.
