Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm
(for ø6.35, 9.52) or 1.0 mm (for ø12.7, ø15.88). Never use any pipe with a thickness
less than 0.8 mm (for ø6.35, 9.52) or 1.0 mm (for ø12.7, ø15.88), as the pressure
resistance is insufficient.

2 Ensure that the 2 refrigerant pipes are insulated to prevent condensation.
3 Refrigerant pipe bending radius must be 100 mm or more.
CAUTION
Be sure to use the insulation of specified thickness. Excessive thickness may cause
incorrect installation of the indoor unit and lack of thickness may cause dew drippage.
