Installation, electrical work and test run
WARNING
Have the unit installed by your agent or specialized contractor. Electrical work needs to be done by a qualified electrical work contractor.
Improper installation made by yourself may cause electric shock, or fire.
Installation should be made properly according to this manual. Otherwise it may cause electric shock, or fire.
Install the condensing unit (CDU) on a sturdy foundation that can bear its weight sufficiently. Imperfect installation may cause injury if it
collapses or crumbles.
Where it is installed in a small room, take measures to prevent the refrigerant from accumulating beyond the critical concentration. For the
measures, consult with your dealer. When the refrigerant has leaked in the room, and accumulated beyond the critical concentration, it could
cause suffocation if the space in the room is limited.
Implement the electrical work according to this manual, and use always dedicated circuits. If it fails to observe descriptions in the manual, the
capacity of circuits becomes insufficient, or the work is done improperly, it could cause electric shock, or fire.
Implement the class D grounding by professional electrical work contractor. Do not connect the grounding cable to the gas pipe, water work
pipe, lightning rod, or grounding cable of telephone. Imperfect grounding could cause electric shock, or fire.
Be sure to install the earth leakage breaker according to appropriate local standard where the unit is installed. Unless it is installed, it could
cause fire, or electric shock, owing to ground fault.
Tighten wire terminals securely to specified torque. If they are not tightened securely, it could cause fire, or electric shock, owing to overheat
on the terminal.
Use specified cables for wiring, and connect them securely, avoiding external force. If they are not connected, or fixed, securely, it could cause
fire.
WARNING
When wiring at site, take care to avoid wires being bit, by small animals like rat. If they are damaged, it could cause fire.
To wash refrigerant pipes, use cleaning solution which is not combustible, or toxic. Use of combustible material like alcohol or ether could
cause explosion, or fire.
Wash refrigerant pipes at outdoor, or where it can be ventilated sufficiently. There is risk of oxygen shortage. If open flame is present nearby,
it could generate toxic gas.
When using a burner, take care not to burn nearby parts, oil return pipe, or sound insulation cover. If the oil return cover is burned, oil under
high pressure will burst out, causing fire, or injury.
