After the unit mounting it must be connected to a drain system as shown in Fig. 6.
The unit must be sloped down toward the drain pipe by 1-2°.
Connect the drain pipe (1), the U-trap (3) and the sewerage system (5) with metal, plastic
or rubber hoses. The hoses (2,4) must be installed at the minimum downward slope of 3°,
i.e. 1 m pipe must be sloped down by 55 mm.
Before starting the unit fill the drain system with water and check that the U-trap is always
filled with water.
Make sure that the water drainage is correct. Wrong connection to sewage system may result
in condensate accumulation inside the unit. The condensate drainage system is designed
for operation at the ambient temperature above 0 °C!
If the ambient temperature is below 0 °C, the condensate drainage system must be heat
insulated and pre-heated.
