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.
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.
