Nibe F730 - Dimensions and Pipe Connections

SYSTEM DIAGRAM
When the exhaust air at room temperature passes
through the evaporator, the refrigerant evaporates be-
cause of its low boiling point. In this way the energy in
the room air is transferred to the refrigerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here the
refrigerant gives off its energy to the heating system
water, whereupon the refrigerant changes state from
gas to liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.

The overflow cup (WM1) can be turned, so that the pipe
can be directed forwards or backwards to simplify con-
nection of the hose to the drain.
