conditioner.
• Prepare for strong wind or earthquake and install the unit fixed in the ground at the specified
place.
- There is a risk of death, property damage, or injury.
• When installing and moving the air conditioner to another site, do not charge it with a differ-
ent refrigerant from the refrigerant R410A specified on the unit.
- If a different refrigerant is mixed with the original refrigerant, the refrigerant cycle may mal-
function and the unit may be damaged.
• Do not use the R22 manifold gauge.
- Always use the high-pressure R410A manifold gauge for a stable charging.
• Do not use the R22 pipes and installation materials for the R410A installation. (do not mix
them up)
- Mixing the R22 refrigerant oil with the R410A oil will cause a hydrolysis, and may lead to fire
or failure of the air conditioner.
• Install the air conditioner onto a sturdy place where it can sustain the weight.
- Improper location may cause the air conditioner to fall and get damaged.
• Do not reconstruct to change the settings of the protection devices.
- If the protection device is shorted and modified, and operated forcibly, fire or explosion may
result.
• Always use a vacuum pump or Inert (nitrogen)gas when doing leakage test or air purge.
- Use of oxygen, compressed air and flammable gases may cause fire and explosion.
There is risk of death, property damage, or explosion.
• Check what kind of fuel gas is used.
- Using an incorrect type of gas may cause the operation failure of the engine and the mal-
function of the engine combustion, and result a carbon monoxide poisoning and the break-
down of the engine.
• Do not combine the exhaust drain hose of the indoor unit and the outdoor unit.
- Combining the exhaust drain hose will make the exhaust flow backward in and increase the
risk of carbon monoxide poisoning.
• Install the outdoor unit properly to prevent a reversed flow of the exhaust gas.
- Exhaust gas flowing backward into a building may cause carbon dioxide poisoning.
• If the air conditioner is installed in a small room, measures must be taken to prevent to refrig-
erant concentration from exceeding the safety limit when the refrigerant leaks.
- If the refrigerant leaks and exceeds the safety limit, hazards due to lack of oxygen in the
room could result.
• Ventilate before operating air conditioner when refrigerant gas leaks.
- If the refrigerant contacts inflammables such as welding flame, hazardous gas may result.
• The power of indoor and outdoor units must be separated when installing.
