attached foam of branches cannot be taken as insulating material.

6) After wrapping the pipe, apply sealing material to completely seal the hole on the wall.
4.3.8 Support and Protection of Pipeline
(1) Support should be made for hanging connection pipe. Distance between each support
cannot be over 1m.
(2) Protection against accidental damage should be made for outdoor pipeline. When pipeline
exceeds 1m, a pinch board should be added for protection.
4.4 Disassembly of Compressor Feet
In order to prevent unit from damage during transportation, 2 metal pieces are fitted to
outdoor unit’s compressor feet before unit leaves factory. See fig.19.
Fig.19
When installing the unit, metal pieces for transportation must be removed. Then fasten the
binding nuts again and wrap back soundproofing cotton.
Note: If unit runs with metal pieces fitting on, compressor will shake abnormally and
unit’s operating life will be shortened.
