After selecting the best location, start installation according to Installation Diagram.
1 Fix the unit on concrete or rigid frame firmly and horizontally by bolt nut (ø10 mm).
2 When installing at roof, please consider strong wind and earthquake. Please fasten the installation stand
firmly with bolt or nails.
Disposal of Outdoor Unit Drain Water
When a Drain elbow is used, please ensure to follow below:
o
the unit should be placed on a stand which is taller than 50 mm.
o
cover the ø20mm holes with Rubber cap (refer to illustration below).
o
use a tray (field supply) when necessary to dispose the outdoor unit drain water.
If the unit is used in an area where temperature falls below 0°C for 2 or 3 consecutive days, it is recommended
not to use the Drain elbow and Rubber cap, for the drain water freezes and the fan will not rotate.

Connecting the Piping to Outdoor Unit
Decide piping length and then cut by using pipe cutter.
Remove burrs from cut edge. Make flare after
inserting the flare nut (locate at valve) onto the copper
pipe. Align center of piping to valves and then tighten
with torque wrench to the specified torque as stated in
the table.
Local pipes can project in any of four directions.
Make holes in the pipe panels for the pipes to
pass through.
Be sure to install the pipe panels to prevent rain
from getting inside the outdoor unit.
