ENGLISH
• 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 snowfallit 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).
COLD AREA RECOMMENDATION

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 3)
Condensate drainage is provided on the unit. The con-
nection is located at the rear.
To ensure correct condensate drainage, the drain line
must be installed with a gradient of at least 2% (2 cm per
meter) and without any upward slopes. An elbow trap at
least 50 mm in height must also be provided.
If possible, install a U bend fitted with an inspection cap.
Where the condensate lines from several units are joined
together, each individual outlet must be fitted with an
elbow trap. After routing and connecting condensate
lines, pour water into the collecting pan and check that it
drains correctly. An auxiliary condensate pump could be
installed in cases where drain lines cannot be routed the
correct gradient.
