1 Safety
Screw Compressor J-series 1.1 Observation/Prevention
1-1
1 Safety
1.1 Observation/Prevention
1.1.1 Observance (Do's)
1.1.1.1 Do's on Operation
Always use the specified controller (CP4) designed for this product.
This controller protects the compressor utilizing sensor output values.
Make sure that all necessary safety devices are installed and the control values for machine protection
are set correctly.
Regularly inspect the safety devices and the controller's protective functions. Ensure that they operate
properly.
If the safety devices and the controller's protective functions do not work properly or the machine
operates abnormally, stop operation immediately and report the incident to your supervisor. Do not
restart the machine until the supervisor determines the machine safety and provides proper instructions
for restart.
If the machine stops due to unknown reasons, immediately inform your supervisor. Do not restart the
machine until the supervisor determines the machine safety and provides the proper instructions for
restart.
Some types of refrigerants generate bad smell or toxic gases and cause oxygen deficiency. Make sure to
ventilate the working area.
Some refrigerants and refrigerant oils may be corrosive, decomposable, or toxic. Make sure to obtain
the Material Safety Data Sheets (MSDS) of the refrigerants and refrigerant oils and follow their
instructions.
When stopping the compressor for a long time, turn "OFF" the main motor, heater, and control power.
Close the suction and discharge side shut-off valves.
1.1.1.2 Do's on Maintenance
When performing work with at least two or more persons, thoroughly confirm the work procedure and
clearly understand each others work before commencement.
Always turn OFF and lockout /tagout the main motor, control and other devices before troubleshooting,
setup, cleaning, maintenance, or inspection of the compressor. Also, make sure that those powers are
NOT turned on accidentally during work.
Always confirm that the pressure inside the package (refrigerating/cold storage/ air conditioning) is
atmospheric before troubleshooting, setup, cleaning, maintenance or inspection of the compressor.
Before troubleshooting, setup, cleaning, servicing or inspection of the compressor, apply lockout/tagout
or other equivalent measures to the liquid supply stop valves and valves in the upstream and
downstream of any opening so that the valves do not open accidentally during the work.
Some types of refrigerants generate bad smell or toxic gases and cause oxygen deficiency. Make sure to
ventilate the air during work.
Some refrigerants and refrigerant oils may be corrosive, decomposable, or toxic. Make sure to obtain
the Material Safety Data Sheets (MSDS) of the refrigerants and refrigerant oils and follow their
instructions.
After working on the machine, always store the tools used at the specified places and make sure that no
tools are left in or around the machine.
1.1.1.3 Do's on Lockout/Tagout after Shutting off the Power
Prepare lockout/tagout devices for the main breakers of the main motor and control power.
By applying lockout/tagout after shutting off the power, you can prevent any other personnel from
activating the machine (power) inadvertently and protect safety of the personnel working inside the
power supply equipment and the package.

2202B0JE-DA-J-N_2012.01.
1 Safety
Screw Compressor J-series 1.1 Observation/Prevention
1-2
If there are any possibilities of danger during work (especially during cleaning, maintenance, inspection,
or troubleshooting), turn "OFF" the main motor and control power, and perform lockout/tagout.
Before entering the package for troubleshooting, setup, cleaning, or maintenance/inspection, always
apply lockout/tagout to the main motor and control power personally.
Shut off the power and perform lockout/tagout before entering the package. Clearly notify the workers
of the necessity of lockout/tagout.
It is assumed that workers do not perform lockout/tagout of the main motor and control power
before starting work because it is troublesome, and only turn "OFF" the main motor and control
power.
It is assumed that workers only turn off main motor and control power and do not lockout/tagout
the main motor and control power, because they think it is not important.
After checking that all the work is finished, the worker who applied lockout/tagout must release them.
1.1.1.4 Do's about Personal Protective Devices
Prepare and use protective devices that comply with the area’s safety standards.
Check the function of each protective device before use.
Wear work clothing, and tighten wristbands.
Do not wear any neckties or jewelry that can get entangled in the moving or rotating parts. A helmet is
recommended to protect your head and hair.
Do not have anything in your pocket to prevent objects from falling into the machine.
1.1.1.5 Strict Do's about Handling of Hazardous and Toxic Substances
Obtain Material Safety Data Sheets (MSDS) from manufacturers of hazardous and toxic substances.
Check the MSDS and follow the handling instructions recommended by the manufacturers to handle
and store those substances.
An example of Material Safety Data Sheet (MSDS) is provided as a reference at the end of this
chapter.
1.1.1.6 Strict Do's about Handling Emergency Situation
Develop an emergency action procedure in accordance with the legal regulations and post it at a safe
place.
1.1.1.7 Strict Do's about Waste Oil, Fluid, and Materials
Disposal of refrigerant and waste oil from the compressor are subject to a number of regulations for
environmental protection purposes. Follow the local, state or federal acts and regulations as well as
your company's rules, when disposing of such waste oil, fluid and materials.
1.1.1.8 Other Strict Do's
Keep the floor around the refrigerating, cold storage, and air conditioning packages clean and provide a
safety aisle.
Use only the safety aisle to move around the equipment. Keep the safety aisle free from any tools and
cleaning fluid.
If water or oil is spilled on the compressor or the floor, immediately wipe it off to prevent workers from
injury caused by slipping.

1.1.2 Prohibition (Don'ts)
Do not remove or relocate any safety device, including electrical interfaces.
Do not disable any safety device by short-circuiting or bypassing without any permission.
Do not leave the compressor unsafe and unattended, by removing the safety cover or some other safety
measures.
Do not touch, clean, or lubricate any part of the compressor especially moving parts when the
compressor is operating.
Do not touch relays or electric systems such as terminal block with bare hands when turning on the
power.
