Install the unit in accordance with the instructions to minimize the risk of damage from earthquakes and
strong winds.
- Improper installation will cause the unit to topple, resulting in serious injury.
The unit must be securely installed on a structure that can sustain its weight.
- Failure to do so will cause the unit to fall, resulting in serious injury.
Seal all openings around pipes and wires to keep out small animals, rainwater, or snow.
- Failure to do so may result in current leakage, electric shock, or damage to the unit.
1-4. Precautions for piping work
Before heating the brazed sections, remove the gas and oil that are trapped in the pipes.
- Failure to do so may generate fire, resulting in serious injury.
Do not purge the air using refrigerant. Use a vacuum pump to evacuate the system.
- Residual gas in the refrigerant lines will cause bursting of the pipes or an explosion.
Do not use oxygen, flammable gas, or a refrigerant containing chlorine for air-tightness testing.
- Doing so may result in an explosion. Chlorine will deteriorate the refrigerant oil.
When installing or relocating the unit, do not allow air or any substance other than the specified refrigerant
to enter the refrigerant lines.
- Any substance other than the specified refrigerant may cause abnormally high pressure in the refrigerant lines,
resulting in bursting of the pipes or an explosion.
After the installation has been completed, check for refrigerant leaks.
- If the refrigerant leaks, oxygen starvation may result. If the leaked refrigerant comes in contact with a heat source,
toxic gas will be generated.
1-5. Precautions for electrical wiring
Include some slack in the power cables.
- Failure to do so may break or overheat the cables, resulting in smoke or fire.
Connections must be made securely and without tension on the terminals.
- Improperly connected cables may break, overheat, or cause smoke or fire.
Tighten all terminal screws to the specified torque.
- Loose screws and contact failure may result in smoke or fire.
Electrical work must be performed by qualified personnel in accordance with local regulations and the
instructions provided in this manual. Only use the specified cables and dedicated circuits.
- Inadequate power source capacity or improper electrical work will result in electric shock, malfunction, or fire.
Install an earth leakage breaker on the power supply of each unit.
- Failure to do so may result in electric shock or fire.
Only use properly rated breakers (an earth leakage breaker, local switch <a switch + fuse that meets local
electrical codes>, or overcurrent breaker).
- Failure to do so may result in electric shock, malfunction, smoke, or fire.
Only use standard power cables of sufficient capacity.
- Failure to do so may result in current leakage, overheating, smoke, or fire.
Proper grounding must be provided by qualified personnel.
- Improper grounding may result in electric shock, fire, explosion, or malfunction due to electrical noise. Do not
connect the ground wire to gas or water pipes, lightning rods, or telephone ground wires.
