Mitsubishi Electric CITY MULTI PURY-P-YNW-A2 Installation Manual page 19

Ⓐ M10 anchor bolt (not supplied)
* Required specification for M10 anchor bolt: Tensile load 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 load of 6.7 kN or more to withstand the short-term load caused by
earthquakes or strong winds
Use the fixing bracket with sufficient strength.
Ⓓ Anti-vibration rubber pad
(The pad needs to be large enough to cover the entire width of each unit leg.)
Detachable leg
Ⓔ
・Make sure that the corner section is securely received. If not, the unit legs could bend.
・The detachable legs must be properly supported by both the anti-vibration rubber pads and the base so that the
unit legs will not be deformed or the refrigerant gas will not leak from the unit pipes. When the detachable legs
are not used, all the bottom corners of the unit must still be supported by both the anti-vibration rubber pads and
the base. Abnormal vibrations that result from improper installation can generate abnormal sound and damage
the pipes, resulting in refrigerant gas leakage.
・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 (six locations for units P500, P550, EP500, and EP550).
・To remove the detachable legs on site, unscrew the screws shown in the figure below. If the unit leg coating is
damaged when the detachable leg is removed, repair the coating on site.

・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)

・Install the unit so that the wind will not blow directly against the inlet and outlet.
・If necessary, install the unit on a raised base of the following specifications (not supplied) to prevent damage
from snow.
Material: Angle iron (Build a structure that snow and wind can pass through.)
Height: Expected maximum snowfall plus 200 mm (7-7/8 in)
Width: Within the unit width (If the raised base is too wide, snow will accumulate on the raised base.)
