The Neo Ductless split heat pumps are single zone
units available in size from 9000 btuh to 36,000 btuh
providing heating and cooling. All comfort settings are
controlled by a remote control. The Neo unit has many
features to enhance comfort and efficiency. The op-
eration of these features will be explained later in this
service manual.
Superior inverter technology is used to control ca-
pacity while maintaining maximum efficiency. The
Neo systems are equipped with G10 inverter technol-
ogy providing precise control over the compressor
frequency based on operating pressures and tem-
peratures. Should an abnormal condition occur, the
software will adjust the compressor frequency or shut
down the system indicating the appropriate fault.
The indoor unit contains a digital display, which will
indicate the current fault. The evaporator, swing mo-
tors, fan motors and circuit board are also components
of the indoor unit. The indoor units have a bypass
switch to bypass the remote control if lost or batteries
fail. This will be explained later in this service manual.
The systems require R410A and are pre-charged for 25’
of lineset. Please refer to your installation manual for
additional charge for linesets longer than 25’.
The maximum allowable line lift and distances vary
by model, please refer to the charts in the manual for
proper lineset applications.
The systems use a PVE oil and should require no ad-
ditional oil. All Neo units utilize an Oil Return Mode
which will return oil to the compressor should the
need arise.
