The following guidelines are intended for the installation of Livezi Digital and Inverter air
trade personnel should carry out installations of Split or Package air conditioning systems.
Full compliance with the local codes and regulations, which govern the installation of the
equipment, is the responsibility of the installer.
Before installation, the electrical power should be checked to determine if adequate power is
available with correct voltage to the site. The position of the equipment, after a survey of the
building and the duct layout, should meet the following criteria.
1.1 Electrical
All wiring by the installer must comply with local Energy Authority wiring rules. To make
the correct connection a 240V 50Hz supply must be available in the case of single-phase
units and a 415V 50Hz supply must be available in the case of three phase units.
During transportation the unit’s electrical connections may become loose, therefore it is
the installer’s / electrician’s responsibility to make sure that all electrical connections are
secure or warranty will be void.
Field or installation wiring must be connected as per the connection diagram to ensure the
unit performs as it is designed (Refer to Appendix A).

Livezi Z-Plus provides a central control point from which system capacity can be adjusted in up
to eight individual zones (rooms). Like most residentially orientated concealed split ducted air
conditioning control products, the Z-Plus provides four main system modes (Cooling, Heating,

is to allow localised adjustment of system capacity based on comfort; avoiding the shortfall
