5.Refrigerant pipe
[The proper thermal insulation must be treated to gas pipe and liquid pipe. If not, it may cause water leakage.]
The outdoor unit is not charged with refrigerant.
When connecting the pipes to unit or dismantling the pipes from the unit, do proceed as the figure shown, use spanner and torque pincers together.
For the dimension of the
When connecting pipes, both the inner or the outside of the
According to Table 1 to confirm the fasten torque. (fasten too tight may damage the screw nut leading to leakage)
After check if the connection pipes leaks, then perform thermal insulation treatment, as the following figure shown.
Only use seal cushion to bind the joint between gas pipe and the insulation parts.

6. Installation of drain hose (1)Install the drain hose
The diameter of the drain hose should be larger than or equal to the diameter of connection pipe.
