CAUTIONS FOR SAFETY
–
Do not use other than the designated refrigerant (for charging,
adding or recharging)
–
Refrigerant gas leak may cause suffocation.
–
Piping, equipment components and tools should be appropriate for
use with R744 (CO2 refrigerant).
–
Use of unsuitable components or those designed for HFC
refrigerant may cause serious incidents such as equipment failure
and rupture of the refrigerant cycle.
–
Securely place the cover on the electrical box and enclosure panel.
Incomplete attachment may lead to penetration of water and living
creatures, meaning potential current leak and fire/electrical shock.
–
Do not change the set values of the safety device.
–
Using the refrigeration unit with changed values may cause failure
of the safety stop function and lead to a burst or fire.
–
When abnormal operation is detected, or before starting
disassembly or repair, turn off the main power switch.
–
Specified components must be used for repair.
–
Use of non-specified components may cause failure of the safety
stop function and lead to burst or fire.
–
Incorrect moving may cause fall or dropping of the refrigeration
unit, and cause injury.
–
Request a specialty operator for disposing the refrigeration unit.
–
Make sure that access and emergency exit ways are not obstructed
to comply with the local regulations.
–
Protect all electrical live parts from rain or snow if doing
maintenance with unit under voltage
