Fasten with bolts

(M10-12)

Use a thicker block to anchor deeper.

Use a long block to

extend the width.

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 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 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

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.

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-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.

In installing the unit, fix the unit’s legs with bolts specified on the left.

●

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.

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

that the bottom is higher than

snow cover surface.

2 Provide a snow hood to

the outdoor unit on site.

3 Install the unit under eaves

or provide the roof on site.

(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.

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.]

1.Install the outlet air blow side of the unit to face a

wall of building, or provide a fence or a windbreak screen.

Wind direction

2.Install the outlet air blow side of the unit in a position

perpendicular to the direction of wind.

Over 500mm

Regarding outline of a snow

hood, refer to our technical

manual.
