3.2.2 System Installation Illustration

The installation modes of the unit are shown in Figure 3-2 and Figure 3-3.
Note
If the condenser is installed higher than the compressor (see Figure 3-2), a back bend should be fitted to the discharge
line and liquid line of the condenser, so as to prevent the liquid refrigerant from flowing back when the condenser stops.
The top end of the back bend must be installed higher than the highest copper pipe of the condenser.
