INDOOR UNIT INSTALLATION
Carry out the pipe and line operation in the ceiling after finishing the installation of the main
body. While choosing where to start the operation, determine the direction of the pipes to
be drawn out. Especially in case there is a ceiling, position the refrigerant pipes, drain pipes,
indoor & outdoor lines to the connection places before hanging up the machine.
The installation of hanging screw bolts.
Wooden construction
Installing f10 hanging screw bolts. (4 bolts)
Please refer to the following figure for the distance measurement between the screw bolts.
Please install with f10 hanging screw bolts.
The handling to the ceiling varies from the constructions, consult the construction personnels for the specific procedures.
1. The size of the ceiling to be handled ... ... do keep the ceiling flat. Consolidate the roof
beam for possible vibration.
2. Cut off the roof beam.
3. Strengthen the place cut off, and consolidate the roof beam.
Put the square timber traversely over the
roof beam, then install the hanging screw
bolts. (Refer to Chart 1)
