The minimum distance between the outdoor unit and obstacles described in the installation chart does not mean
that the same is applicable to the situation of an airtight room. Leave open two of the three directions (A, B, C).

MOVING AND INSTALLING
• Since the gravity center of this unit is not at its physical center, so please be careful when lifting it with a sling.
• Never hold the air-in of the outdoor unit to prevent it from deforming.
Do not touch the fan with hands or other objects.
• Do not lean it more than 45°, and do not lay it sidelong.
• Please fasten the feet of this unit with bolts firmly to prevent it from collapsing in case of earthquake or strong
wind.
• Make concrete foundation of the size of 590 x 328. (Refer to chart 18)
COLD AREA RECOMMENDATION
• Outdoor heat pump unit: install the unit at least 10 cm. above ground level to facilitate drainage of defrost water
and prevent accumulation of ice. In effect, defrost water can cause accumulation of ice under the unit during
subfreezing outdoor temperatures.
• In areas with heavy snowfall, it is best to install the unit on wall supports.
• In some regions, it is necessary to heat the bottom of the condensate drainage pan and the condensate drainage
piping to avoid ice formation, and resulting ice build-up in the fan compartment (heater strip must be at least
25 W/m).
