5.1 Safety Precautions for Maintenance
Be careful so as not to receive an electrical shock when turning on/off the power of each unit.
Before performing maintenance, turn off the motor (main power) and control power, and then perform
lockout and tagout.
Before performing maintenance, turn off the power of instruments such as a heater. Be careful so that
the power of instruments does not turn on during maintenance.
Check that pressure inside the refrigerating machine is at atmospheric pressure before disassembling the
machine for inspection.
After temperature of the hot sections (such as head cover) is decreased to normal, perform the work.
When handling the heavy objects, take a sufficient care and perform the work using an auxiliary tool
such as a stud bolt.
Always handle the heavy objects with at least one other person.
Before performing the work together with at least one other person, thoroughly confirm each other's
work details and acknowledge other worker's movement.
Replace the parts with the
genuine parts.
When disassembling/assembling the refrigerating machine, use a normal tool that has been designated.
Electrical works should be performed only by electrical engineers.
