UNIT INSTALLATION SPACE REQUIREMENTS
9.1 Selection of outdoor unit installation site
VRF units are used in a lot of situations and serve wider users. If the unit is installed in a living environment, the cooling, heating and noise requirements will be higher, especially for the aged and infants. Therefore, the indoor/outdoor unit model with sufficient capacity and low noise should be preferred during model selection. It is not advisable to install the outdoor unit outside the bedroom, study room, or meeting room. For the commercial site, it is improper to install the outdoor unit near the office.

2) If there is a crown wall (such a barrier against wind) above the machine top, the machine top should be more than 3000 mm away from the crown wall in principle. If the spaces around the front, rear, left side, and right side of the machine are all open spaces, the machine top should be more than 1500 mm away from the crown wall, as shown in Figure (a). If the dimension is less than 1500 mm or the spaces around the machine are not open spaces, it is required to use a return duct to keep smooth ventilation, as shown in Figure (b).

Figure (a) Figure (b)Installation space requirements of multiple outdoor unitsTo ensure smooth ventilation, an open space must be ensured above the unit top, and there is no barrier against wind.If there is an open space at the front side and left side (or right side) of the outdoor unit, the units should
be installed towards the same direction or reverse direction.

The height of the base should higher than that of the snowfall.
5) When the outdoor unit is installed on equipment, an air exhaust pipe should be connected, the aperture opening ratio of the louver cannot be smaller than 80%, and the included angle between the louver and the horizontal plane should be smaller than 20°.
