RECEPTION AND POSITIONING
■ When installing the unit in a place exposed to strong wind, pay special attention to the following .
Strong winds of 5 m/sec or more blowing against the unit's air outlet causes a short circuit (suction of discharge air), and this
may have the following consequences:

- Deterioration of the operational capacity .
- Frequent frost acceleration in heating operation .
- Disruption of operation due to rise of high pressure .
- When a strong wind blows continuously on the front of the unit,
the fan can start rotating very fast until it breaks .
Refer to the figures for installation of this unit in a place where the
wind direction can be foreseen .
■ Turn the air outlet side toward the building's wall, fence or screen.
Make sure there is enough room to do the installation
■ Set the outlet side at a right angle to the direction of the wind.
■ Prepare a water drainage channel around the foundation, to drain
waste water from around the unit .
■ If water does not easily drain from the unit, mount the unit on a
foundation of concrete blocks, etc . (the height of the foundation
should be about 100 mm .
■ If you install the unit on a frame, please install a waterproof plate
(about 100 mm) on the underside of the unit to prevent water from
coming in from the low side .
■ When installing the unit in a place frequently exposed to snow, pay
special attention to elevate the foundation as high as possible .
Selecting the installation site
■ Be sure to provide for adequate measures in order to prevent that the unit be used as a shelter by small animals. Small animals
making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep
the area around the unit clean .
WARNING
■
In heavy snowfall areas it is very important to select an installation site where the snow will not affect the unit.
If lateral snowfall is possible, make sure that the heat exchanger coil is not affected by the snow (if necessary
construct a lateral canopy).
■
As the outdoor temperature is measured via the outdoor unit air thermistor, make sure to install the outdoor
unit in the shade, or a canopy should be constracted to avoid direct sunlight, so that it is not influenced by the
sun’s heat, otherwise protection may be possible to the unit.
■
Check the strength and level of the installation ground so that the unit will not cause any operating vibration or
noise after installation.
■
In accordance with the foundation drawing in the figure, fix the unit securely by means of the foundation bolts.
(Prepare four sets each of
Ø
10 Expansion bolts, nuts and washers which are readily available on the market.)
■
It is best to screw in the foundation bolts until their length is 20 mm from the foundation surface.
Select an installation site where the following conditions are satisfied and one that meets with your customer's approval.
- Places that are well-ventilated .
- Places where the unit does not disturb next-door neighbors .
- Safe places which can bear the unit's weight and vibration and where the unit can be installed at an even level .
- Places where there is no possibility of flammable gas or product leak.
- The equipment is not intended for use in a potentially explosive atmosphere .
- Places where servicing space can be well ensured .
- Places where the units' piping and wiring lengths come within the allowable ranges .
- Places where water leaking from the unit cannot cause damage to the location (e .g . in case of a blocked drain pipe) .
- Places where rain can be avoided as much as possible .
- Do not install the unit in places often used as a work space . In case of construction work (e .g . grinding etc .) where a lot of dust
is created, the unit must be covered .
- Do not place any objects or equipment on top of the unit (top plate)
- Do not climb, sit or stand on top of the unit .
- Be sure that sufficient precautions are taken in case of refrigerant leakage according to relevant local laws and regulations.
