5 Make a water trap which meets the measurements on the illustration and
pour water in it. Alternatively you can use the water trap from Dantherm Air
Handling (accessories):
6 Connect the hose to the drain. The drain pipe must be kept frost proof all the
way to ensure that the water can run unhindered.
The drain pipe must at least fall by 1% all the way from the unit to the drain
outlet.
7 Dantherm Air Handling recommends isolated flex ducts when connecting to
flanges. The ducts must be completely stretched to avoid unnecessary loss
of pressure.
Mount the ducts on the unit. Make sure you connect the ducts to the right
flanges:
HCV 3 also has a supply air outlet in the bottom which can be used in stead
of the one in the top. The unused outlet must be covered.

8 Insulate the entire duct system with 100 mm insulation. For example, place
the ducts below the insulation of the ceiling. If the insulation is wrapped
around the tube, it is recommended to apply two layers of foil.
9 Wrap the two layers staggered, and tape the area where the two layers meet
until air tight.
10 Insulate all flex ducts as well as the entire duct system. It is important that
especially the exhaust air duct is insulated, to avoid the possibility of con-
densation inside the duct, which can lead to water in the unit
11 Choose the right power supply cable matching the regulation in the actual
country and connect the cable's IEC plug to the unit and connect the unit to
230 V AC.
