Supply and extract ducts:
To minimise heat losses from the duct system cold loft
spaces, the supply and extract ducts must insulated
with minimum 100 insulation. B
Faulty duct insulation
Condensate drain
The units produce litres condensate per day.
Insulation ducts cold loft spaces
In order exploit the unit’s high recovery potential
(efficiency), necessary insulate the ducts correctly.
Fresh air and escaping ducts cold spaces:
It recommended that fresh air and escaping ducts
are insulated with minimum insulation.
Use armed water hose between the drain connecting
piece the unit and the siphon and tightend both
ends with collar band.
If installation problems make impossible secure the
condensate drain pipe from freezing insulation, will be
necessary mount thermostat-controlled heating tape
round the condensate drain pipe. insulation form
alternative used, recommended that executed
with two layers lamella mats with paper foil
externally and with staggered joints between the two
layers. The condensate drain must be
fitted with water trap there negative pressure the
chamber which the condensate tray mounted. It
is therefore important that the condensate drain correctly
executed and that the unit has slight fall towards the
condensate drain.

The condensate drain pipe must air tight for example by
bending copper pipe siphon (see sketch the left). The insulation must always tightly packed
round the ducts.
From the siphon and the internal outlet there must be
a necessary fall 1%.
If the unit installed cold loft space, the condensate
drain pipe must insulated prevent freezing the
condensate the pipe. The
fresh air duct insulated prevent warm air the loft in
summer from heating the fresh air. Take care seal the
termination where the escaping duct led through the roof
or through the gable end, order avoid condensation
damage. However, recommended that
the water trap installed heated space below to
ensure that the water does not freeze.7Subject Technical Modifications Energy and 3/GES Energy 1
