1. HAULAGE AND INSTALLATION
(Take particular care in carrying in or moving the unit, and always perform such an operation with two or more persons.)
CAUTION
When a unit is hoisted with slings for haulage, take into consideration the offset of its gravity center position.
If not properly balanced, the unit can be thrown off-balance and fall.
1) Delivery
● Deliver the unit as close as possible to the installation site before removing it
from the packaging.
● When some compelling reason necessitates the unpacking of the unit before it
is carried in, use nylon slings or protective wood pieces so as not to damage
the unit by ropes lifting it.
2) Portage
● 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

2.Install the outlet air blow side
of the unit in a position
perpendicular to the direction
of wind.
3.The unit should be installed on
the stable and level foundation.
If the foundation is not level,
tie down the unit with wires.
1.Install the outlet air blow side
of the unit to face a wall of
building, or provide a fence or
a windbreak screen.
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
A place where it can be free from danger of flammable gas leakage.
〇 A place where drain water can be disposed without any trouble.
〇 A place where the unit will not be affected by heat radiation from other heat source.
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.
〇
A place where the unit will not be affected by electromagnetic waves and/or high-harmonic waves generated by other
equipment.
〇 A place where chemical substances like sulfuric gas, chloric gas, acid and alkali (including ammonia), which can harm
the unit, will not be generated and not remain.
〇
A place where strong wind will not blow against the outlet air blow of the unit.

4) Caution about selection of installation location
(1) If the unit is installed in the area where the snow will accumulate, following measures are required.
The bottom plate of unit and intake, outlet may be blocked by snow.
Since drain water generated by defrost control may freeze, following measures are required.
● Don't execute drain piping work. by using a drain elbow and drain grommets (optional parts). [Refer to
Drain piping work.]
● Recommend setting Defrost Control (SW3-1) and Snow Guard Fan Control (SW3-2). [Refer to Setting SW3-1,
SW3-2.]
(2) If the unit can be affected by strong wind, following measures are required.
Strong wind can cause damage of fan (fan motor), or can cause performance degradation, or can trigger
anomalous stop of the unit due to rising of high pressure.
1.Install the unit on the base so that
the bottom is higher than snow cover
surface.
3.Install the unit under
eaves or provide the roof
on site.
2. Provide a snow hood to
the outdoor unit on site.
Regarding outline of a snow
hood, refer to our technical
manual.

5) Installation space
● Walls surrounding the unit in the four sides are not acceptable.
●
There must be a 1-meter or larger space in the above.
● Where a danger of short-circuiting exists, install guide louvers.
●
When more than one unit are installed, provide sufficient intake space consciously so that short-circuiting may not occur.
