5.8.1
Installation and routing of refrigerant lines for condensing units
During installation and commissioning take the following points into consideration:
1. First of all consider the refrigerant lines to connect the MCCY unit with the evaporator section. To limit loss of
cooling capacity ensure that the refrigerant lines are as short as possible and reduce the number of bends to a
minimum, avoiding possible flow restrictions caused by excessively tight bends. It is essential to comply with the
maximum equivalent lengths and maximum level differences shown in the following table:
On the back site of the MCCY 081÷301 units there are refrigerant connections (see figure above) that have to be welded,
the dimensions of their diameter are indicated in the table below.
