Page 14: Indoor Unit Installation
Installation details 3.2 The outdoor unit installation needs to be fixed on the bottom frame with expansion screws, and the bottom corner of the main unit needs to be installed with a cushion Anti-shock pad Concrete basic Expansion bolt 4. Indoor unit installation: 4.1 Indoor unit installation requires three expansion screws to fix the internal unit to the wall. - Page 15 Pipes connection 5. Fix the connecting pipe 5.1 After the outdoor door unit and indoor unit are fixed, look for the nearest connection route, punch a hole of 50-100mm at the location of the wall, pay attention to waterproof when drilling 5.2 Pass the two connecting pipes through the wall, and place the two ends at the connection between the indoor and outdoor units 6.
