Cautions for Safety
When the refrigerant bursts out, shut off the power
and fully close the service valve.
Blowout of refrigerant from the refrigeration
cycle by opening the service valve would
cause insufficient oxygen and harm human
health.
Do not touch electrical components by a wet hand.
Switching operation by a wet hand may
cause electrical shock and injury.
Periodically check operation of the ground fault
interrupter.
Failed interrupter does not operate safety
stop function and may lead to fire or
electrical shock.
Do not ride on the refrigeration unit.
Riding on the refrigeration unit or placing
an article on it may lead to falling or
dropping by vibration and cause injury.
Periodically check the installed base.
Damaged base after a long-time use may
cause the refrigeration unit to fall or drop
and lead to injury.
Request a specialty operator for disposing the
refrigeration unit.
Disposal with the refrigerant and oil inside
the refrigeration unit may cause fire or
explosion.
Cautions for Use
Do not use flammable spray near the refrigeration
unit. Do not place flammable materials nearby.
Before any inspection service, turn off the power
switch and shut down the ground fault interrupter.
When removing the fin guard of the gas cooler, do
not touch the fin.
Do not operate with the service valves of each stage
around the compressor kept closed.
Disposal
Be sure to comply with the following
Flammable material may catch fire from
switch spark.
Inspection work with power on may lead to
electrical shock, interference with the
moving mechanism, and heat generation,
thereby leading to injury and skin burn.
Touching the fin and sliding along the fin
may cause skin cut by the fin edge.
Operating the compressor with the
discharge service valve of each stage
closed, would generate abnormally high
pressure and may lead to rapture.
