Installation procedure
Install the lifting tools on the lifting bolts according to the instructions in Fig. 2
Follow the stipulations on products locally purchased to use nuts (M8 or M10 of 3 pieces for 4 positions) and gaskets
(M8 with an outer diameter of 24–28 mm and M10 with an outer diameter of 30–34 mm of 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 the Fig. 2) upward, or the appliance will
not work well and increase the working noise.

4. Refrigerant pipe Installation
• For installation of pipes between the outdoor unit and connection kit, selection of refrigerant branching suite, and For
installation of pipe between refrigerant branching suites and the indoor units, please refer to the installation
instructions or equipment design data attached to the outdoor unit.
• Before installation, ensure the refrigerant used is R410A. (If a refrigerant other than this is used, the appliance will
not run properly)
• Provide thermal insulation for the gas pipe, liquid pipe, and the connections between these pipes. In the absence of
thermal insulation, liquid leakage and scalding may occur. The thermal insulation material should be able to
withstand temperatures over 120°C.
• Enhance the thermal insulation material based on the installation environment. The indicators are shown below.
For RH between 75% and 80% at 30°C: over 15-mm thick.
For RH over 80% at 30°C: over 20-mm thick.
If not reinforced, the thermal insulation material surface may be prone to condensation.
Please refer to the equipment design data for further details.
The outdoor unit is already filled with refrigerant.
