5.2.6 DIRECT EVAPORATOR CONNECTION
The unit equipped with a direct evaporator (DX, DXr) is connected via a Cu pipe to the appropriate condensing unit or heat pump (the method
and design of the connection is not the subject of these installation instructions). The direct cooler outlets are located outside the unit and passed
to the operation side. The evaporator is filled with dry air or nitrogen from the factory.
After removing the valves on the evaporator necks,
work on the refrigerant circuit assembly must begin immediately.
The connection of the refrigerant circuit for direct cooling must be carried
out by a specialist company. It is mandatory to perform a "Refrigerant leak test" on the refrigerant circuit. This test is performed only by a
technician with the appropriate authorization (according to the law).
5.2.7 CONDENSATE DRAIN CONNECTION
To ensure the drainage of condensate the drain neck must be connected to the sewerage system via a siphon with an odour trap. As standard,
the condensate neck is located under the rotation regeneration exchanger. In the unit configuration with water cooler or direct evaporator, the
condensate drain is located under the cooler or direct evaporator.
