1. HAULAGE AND INSTALLATION
When a unit is hoisted with slings for haulage, take into consideration the offset of its gravity
CAUTION
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 you have to unpack the unit for a compelling reason before you haul it to the
installation point, hoist the unit with nylon slings or ropes and protection pads so that
you may not damage the unit.
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 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 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 enoug hservice 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 (includingammonia), which can
harm the unit, will not be generated and not remain.
〇 If a operation is conducted when the outdoor air temperature is -5˚C lower, the outdoor unit should be installed
at a place where it is not influenced by natural wind.
〇 A place where strong wind will not blow against the outlet air blow of the unit.
Do not install the unit in places which exposed to sea breeze (e.g. coastal area) or calcium chloride (e.g. snow
melting agent), exposed to ammonia substance (e.g. organic fertilizer).
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.
1 Install the unit on the base so 2 Provide a snow hood to
that the bottom is higher than
snow cover surface, and
draining water is secured.
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 (accessories).
[Refer to Drain piping work.]
● Attached heater on a base plate on site, if there is possibility to freeze drain water.
In case that the product has a corrective drainage system, the drainage paths should have suitable
threatment against freezing but be sure not to melt the material of drainage paths with heat.
2. REFRIGERANT PIPING WORK

(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.

Over 500 mm
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.
●
● When more than one unit are installed side by side, provide a 250mm or wider interval between them as a service
space. In order to facilitate servicing of controllers, please provide a sufficient space between units so that their
top plates can be removed easily.
● Where a danger of short-ci rcuiting exists, install guide louvers.
● When more than one unit are installed, provide sufficient intake space consciously so that short-ci rcuiting may not occur .
● Where piling snow can bury the outdoor unit, provide proper snow guards.

● In installing the unit, fix the unit 's legs with bolts specified on the above.
● The protrusion of an anchor bolt on the front side must be kept within 15 mm.
● Securely install the unit so that it does not fall over during earthquakes or strong winds, etc.
● Refer to the above illustrations for information regarding concrete foundations.
● Install the unit in a level area. (With a gradient of 5 mm or less.)
Improper installation can result in a compressor failure, broken piping within the unit and abnormal noise generation.
7) To run the unit for a cooling operation,
when the outdoor temperature is -5°C or lower.
● When the outdoor air temperature is -5°C or lower, provide a snow hood to the outdoor unit on site.
So that strong wind will not blow against the outdoor heat exchanger directly.
