CONDENSATE DRAINAGE
The drain pan is equipped with drain pipes for condensate removal
outside the unit.
Connect the drain pipe, the U-trap (not included into the delivery set)
and a sewage system with metal, plastic or rubber drain hoses (Fig. 13). While
laying the hoses provide the slope downward min. 3%. Fill the system with
water prior to connecting it to power supply! The U-trap must always be filled
with water. Provide free drainage for the condensed water, otherwise it is
accumulated inside the unit which may cause the equipment damage and
condensate outflow to the room.
The condensate drain system is suitable for indoor frost-free
application with the ambient temperature above 0°C!
If the expected ambient temperature is below 0°C provide heating
for the drain system.
WARNING
In case of several units mounting connect each unit to an individual U-trap. Direct condensate drainage with no connection to the
drain system is not allowed.
