8. Foundation work
Install the unit in accordance with the instructions to minimize the risk of damage from earthquakes and strong winds.
- Improper installation will cause the unit to topple, resulting in serious injury.
To reduce the vibration of the unit operation, irrespective of the cause of the vibration such as
earthquakes and strong winds, perform the foundation work in accordance with the installation
instructions (including the instructions for installing anti-vibration rubber pads) provided in this section.
Take adequate measures against natural disasters including earthquakes and windstorms so that the
unit will not fall or tip over. Consult your local specialist for safety measures to be taken.
The unit must be securely installed on a structure that can sustain its weight.
- Failure to do so will cause the unit to fall, resulting in serious injury.
・When performing the foundation work, make sure that the floor surface has sufficient strength and carefully route pipes and wires in consideration
of the water drainage that will be required when the unit is operated.
・If considering routing the pipes and wires across the bottom of the unit, make sure that the base is at least 100 mm (3-15/16 in) high so that the
through-holes will not be blocked.
・Provide a strong base of concrete or angle iron. If a stainless steel base is used, insulate the area between the base and the outdoor unit by
putting a rubber cushion or by applying an electrically insulated coating to prevent the base from rusting.
・Install the unit on a level surface.
・With some types of installation, unit vibration and sound will be transmitted to the floors and walls. In such locations, take measures to prevent
vibration (such as using anti-vibration rubber pads).
M10 anchor bolt (not supplied)
Ⓐ
* Required specification for M10 anchor bolt: Tensile strength of 5.6 kN or more to withstand the short-term load caused by earthquakes or
strong winds
Ⓑ
(Incorrect installation) The corner section is not securely received.
Ⓒ
Fixing bracket for M12 hole-in anchor bolt (not supplied) (to be fixed with three M5 self-tapping screws)
* Required specification for M12 hole-in anchor bolt: Tensile strength of 6.7 kN or more to withstand the short-term load caused by
earthquakes or strong winds
Anti-vibration rubber pad (The pad needs to be large enough to cover the entire width of each unit leg.)
Ⓓ
・The length of the projecting part of the anchor bolt should be 30 mm (1-3/16 in) or less.
・This unit is not designed to be anchored with post-installed anchor bolts unless fixing brackets are installed at the bottom four locations.
・In abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to guard against excessive wind and snow should be
taken to ensure the unit's correct operation. When the unit is expected to operate in cooling mode in conditions under 10°C (50°F), in snowy areas, in
environments subject to strong winds or rain, install snow hoods of the following specifications (not supplied) as shown in the figure below.
Material: Galvanized steel plate 1.2T
Painting: Overall painting with polyester powder
Color: Munsell 5Y8/1 (same as the unit color)
