● Carry out the electrical work for ground lead with care

Do not connect the ground lead to the gas line, water line, lightning conductor or telephone line's ground lead. Incorrect grounding can cause unit faults such as

electric shocks due to short-circuiting. Never connect the grounding wire to a gas pipe because if gas leaks,it could cause explosion or ignition.

● Use the circuit breaker for all pole with correct capacity.

● Install isolator or disconnect switch on the power source wiring in accordance with the local codes and regulations.

The isolator should be locked in accordanced with EN60204-1．

● Take care when carrying the unit by hand.

If the unit weights more than 20kg, it must be carried by two or more persons. Do not carry by the plastic straps, always use the carry handle when carrying the

● Dispose of any packing materials correctly.

Any remaining packing materials can cause personal injury as it contains nails and wood. And to avoid danger of suffocation, be sure to keep the plastic

wrapper away from children and to dispose after tear it up.

● Pay attention not to damage the drain pan by weld spatter when welding work is done near the indoor unit.

If weld spatter entered into the indoor unit during welding work,it can cause pin-hole in drain pan and result in water leakage.To prevent such damage,keep the indoor unit in its packing or cover it.

● Be sure to insulate the refrigerant pipes so as not to condense the ambient air moisture on them.

● Be sure to perform air tightness test by pressurizing with nitrogen gas after completed refrigerant piping work.

If the density of refrigerant exceeds the limit in the event of refrigerant leakage in the small room, lack of oxygen can occur, which can cause serious accidents.

● Perform installation work properly according to this installation manual.

Improper installation can cause abnormal vibrations or increased noise generation.

● Earth leakage breaker must be installed

● Do not use any materials other than a fuse with the correct rating in the location where fuses are to be used.

● Do not install the unit near the location where leakage of combustible gases can occur.

● Do not install the unit where corrosive gas (such as sulfurous acid gas etc.) or combustible gas (such as thinner and petroleum gases) can

accumulate or collect, or where volatile combustible substances are handled.

●

● When the outdoor unit is installed on a roof or a high place, provide permanent ladders and handrails along the access route and fences and handrails around the outdoor unit.

If safety facilities are not provided, it can cause personal injury due to falling from the installation place.

●

Equipment such as inverters, standby generators, medical high frequency equipments and telecommunication equipments can affect the system, and cause

malfunctions and breakdowns.The system can also affect medical equipment and telecommunication equipment, and obstruct its function or cause jamming.

● Do not install the outdoor unit in a location where insects and small animals can inhabit.

Notabilia as a unit designed for R410A

●

Do not use any refrigerant other than R410A. R410A will rise to pressure about 1.6 times higher than that of a conventional refrigerant.

A cylinder containing R410A has a pink indication mark on the top.

●

A unit designed for R410A has adopted a different size indoor unit service valve charge port and a different size check joint provided in the unit to prevent the charging of a wrong refrigerant by mistake. The

R410A tools listed in the table on the right before installing or servicing this unit.

●

Do not use a charge cylinder. The use of a charge cylinder will cause the refrigerant composition to change, which results in performance degradation.

●

In charging refrigerant, always take it out from a cylinder in the liquid phase.

●

All indoor units must be models designed exclusively for R410A. Check connectable indoor unit models in a catalog, etc. (A wrong indoor unit, if connected into the system, will impair proper system operation)

The right hand side of the unit as viewed from the front (diffuser side) is heavier. A person

carrying the right hand side must take heed of this fact. A person carrying the left hand side

must hold with his right hand the handle provided on the front panel of the unit and with his left

hand the corner column section.

3) Selection of installation location for the outdoor unit

Be sure to select a suitable installation place in consideration of following conditions.

〇 A place where it is horizontal, stable and can endure the unit weight and will not allow vibration transmittance of the unit.

〇 A place where it can be free from possibility of bothering neighbors due to noise or exhaust air from the unit

〇 A place where the unit is not exposed to oil splashes.

〇

〇 A place where drain water can be disposed without any trouble.

CAUTION

(Take particular care in carrying in or moving the unit, and always perform such an operation with two or more persons.)

〇 A place where the unit will not be affected by heat radiation from other heat source.

Pad

〇 A place where snow will not accumulate.

〇 A place where the unit can be kept away 5m or more from TV set and/or radio receiver in order to avoid any radio or TV interference.

〇 A place where good air circulation can be secured, and enough service space can be secured for maintenance and service of the unit safely.
