 Note
1. When the condenser is installed higher than the compressor (see Figure 2-6), a back bend should be fitted on the discharge pipe
and liquid pipe of the condenser, to avoid refluence of liquid refrigerant upon stopping.
2. When installing the back bend, ensure that the top end of the back bend is installed higher than the highest copper pipe of the
condenser.
