Figure 2-9 Condenser is Placed Higher than the Compressors during Installation
If the condenser is installed higher than the compressor (see Figure 2-9), a back-bend should be tted to the
discharge line and liquid line of the condenser, so as to prevent the liquid refrigerant from owing back when
the condenser stops. The top end of the inverted back-bend should be installed higher than the ultimate level
of the copper pipe of the condenser. However, if the condenser is installed lower than the compressor, then
there is no need of modication.
