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.
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.
(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 that the bottom is
higher than snow cover surface.
Since drain water generated by defrost control may freeze, following measures are required.
Do not execute drain piping work by using a drain elbow and drain grommets (accessories).
[Refer to Drain piping work.]
2 Install the unit under or provide the roof on site.
Be sure to select a suitable installation place in consideration of following conditions.
A place where it is horizontal, stable and can endure the unit weight and will not allow vibration transmittance
of the unit.
A place where it can be free from possibility of bothering neighbors due to noise or exhaust air from the unit.
A place where the unit is not exposed to oil splashes.
A place where it can be free from danger of flammable gas leakage.
A place where drain water can be disposed without any trouble.
A place where the unit will not be affected by heat radiation from other heat source.
A place where snow will not accumulate.
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.
A place where good air circulation can be secured, and enough service space can be secured for maintenance
and service of the unit safely.
A place where the unit will not be affected by electromagnetic waves and/or high-harmonic waves generated
by other equipment.
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.
If a operation is conducted when the outdoor air temperature is -5 lower, the outdoor unit should be installed
at a place where it is not influenced by natural wind.
A place where strong wind will not blow against the outlet air blow of the unit.
4) Caution about selection of installation location
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-circuiting exists, install guide
louvers.
When more than one unit are installed, provide sufficient
intake space consciously so that short-circuiting may not
occur.
Where piling snow can bury the outdoor unit, provide
proper snow guards.
1 Anchor bolt fixed position
Fasten with bolts
(M10-12)
Use a thicker block to anchor deeper.
Use a long block to extend the width.
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 15mm.
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 5mm or less.) Improper installation can result in a
compressor failure, broken piping within the unit and abnormal noise generation.
2 Notabilia for installation
(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 Place the unit outlet side is turned to the wall. 2 Install so the direction of the air from the
blowing outlet will be perpendicular to the
direction of the wind.
