Installation and connection
Select the model and the number of outdoor unit connection piping kits that you need based on the sales catalog, design engineering, and the
data book and installation manual of outdoor unit.
CAUTION
• When brazing the refrigerant pipes, be sure to put the nitrogen first to prevent from oxidizing the inner pipe. If not, the oxidization scale
brings the refrigerant cycle clogging and result in malfunction.
• Use clean new pipes for the refrigerant pipes, and do not let water, moisture or dust get into the pipes during installation.
