Installing the refrigeration link
1. Install the refrigerant connection pipes between the indoor module
and the outdoor unit.
2. Ensure the minimum bending radii of 100 to 150 mm and the pipe
characteristics are observed.
3. Cut the pipes with a pipe cutter and deburr; angle the opening in the
pipe downwards to ensure no particles can get inside.
4. After completing the installation and all checks necessary before
commissioning, add refrigerant fluid if the refrigeration connection
pipes are more than 10 metres long.
Quantity of refrigerant fluid to be added
If the refrigeration connection pipes are more than 10 metres long, add
more refrigerant fluid.

Prevent oil traps.
If the pipes are not connected immediately, plug them to prevent
moisture from entering.
