System Installation
The system installation schema is defined in Figure 2-12:
Figure 2-12 The Condenser is higher than the Compressor during installation
• The Condenser is installed higher than the Compressor. Therefore, an inverted back
bend is fitted to the discharge line and liquid line of the condenser. This modification
is important as it helps prevent the liquid refrigerant from flowing back once the
condenser stops. Remember that the top-end of the inverter back-bend must be
installed higher than the ultimate level of the copper pipe of the condenser.
• However, if the condenser is installed lower than the compressor, no modification is
needed as it fits the bill perfectly.
• Figure 2-13 depicts the schema of system installation when the condenser is
installed at a lower level than the compressor:
