ATTENTION
Danger of leakages due to incorrect tool
Using a wrong tool, e.g. a pipe wrench, can deform or damage the are nut. This can cause
leakages.
► Use a suitable adjustable spanner or ring spanner.
Danger of leakages caused by exceeding the tightening torque
Too high a tightening torque can cause deformation and consequently leakages.
► Observe the correct torque when tightening the are nut (→ Permissible tightening
torques of refrigerant pipes (All in One units), p. 162, → Permissible tightening torques
of refrigerant pipes (Hydrokits), p. 163, → Permissible tightening torques of refrigerant
