Installation procedure
Install the lifting tools into the lifting bolts, as indicated in Fig.2
Ensure that you are using specified, locally purchased products such as M8 or M10 nuts (3 pieces for 4
positions) and M8 gaskets with the outer diameter of 24~28 mm and M10 with that of 30~34 mm (2 pieces for
4 positions) on the upper and lower sides of the lifting tools.
<Note>
Ensure that the product is installed with the top surface (the oblique surface in Fig.2) facing upwards, or it will
not function well and the working noise from the unit will increase.

4. Refrigerant pipe Installation
• Please choose the pipes between the outdoor unit and connection kit, selection of refrigerant branching
suite, and the pipe between the refrigerant branching suites and the indoor units, in accordance to the
installation instructions or equipment design data attached to the outdoor unit.
• Before installation, ensure the type of the refrigerant used is R410A. (If a refrigerant other than this type is
used, the unit won't function properly)
• Please thermal insulate the gas pipe, liquid pipe and the connections between these pipes. In the absence
of thermal insulation, liquid leakage and scalding may occur. Please use a thermal insulation material that
can sustain temperatures over 120°C.
• Enhance the thermal insulation material based on the installation environment. The indicators are shown
below:
For RH75%–80% at 30°C: over 15 mm thick.
For over 80% at 30°C: over 20 mm thick.
If not reinforced, the thermal insulation material surface is prone to condensation. Please refer to the
equipment design data for further details.
The outdoor unit is already equipped with the refrigerant.
