If ice formation is unknown place the wire all over the inlet side for a flooded evaporator like shown on the drawing.
For a DX evaporator the wire must pass through the evaporator.
The distance between the vertical sections of the wire (windings) can be varied from 100 to
1000mm depending on evaporator size and wire length. When estimating length to be ordered,
consider both the vertical sections of the wire and the connecting, horizontal arches.
Note: when calibrating the HBDF, only consider the active, vertical sections of the wire. The
wire length is measured in mm.
The free end of the wire must end outside the evaporator, and it must be isolated from the
evaporator. Use the terminal connector delivered together with the wire.
HBDF-snap on Clip can be used for securing the wire but passing behind the pipes provide a better and more secure
fastening. The clip requires minimum 5 mm fin spacing.
Installation examples
The wire does not need to cover the entire surface as long as it is installed in an area where ice is formed.

The temperature sensor should
be placed were ice melt slowly.
Keep away from the hot tubes
or electrical elements used for
defrosting.
