Duct connection
All duct connections are with a yellow sticker indicating the
type of ventilation pipe to be connected.
Connect the supply air :
Duct system from the unit to the supply outlet in the living
area.
Connect the extract air :
Duct system from wet rooms to the unit.
Connect the fresh air :
Duct system from fresh air roof cowls/external grills from or
the ground collector to the unit.
Connect the exhaust air :
Duct system from unit to the escaping roof cowls/external
grills.
Condensate drain
The units produce up to 6 litres of condensate per day. It is
therefore important that the condensate drain is correctly
executed and that the unit has a slight fall towards the
condensate drain.
The condensate drain pipe must be air tight for example by
bending a copper pipe as an siphon (see sketch to the left).
Use an armed water hose between the drain connecting
piece on the unit and the siphon and tightend it in both
ends with a collar band.
From the siphon and to the internal outlet there must be
a necessary fall on 1%. The condensate drain must be
fitted with a water trap as there is negative pressure in the
chamber in which the condensate tray is mounted.
If the unit is installed in a cold loft space, the condensate
drain pipe must be insulated to prevent freezing of the
condensate in the pipe. However, it is recommended that
the water trap is installed in a heated space below to
ensure that the water in it does not freeze.
If installation problems make it impossible to secure the
condensate drain pipe from freezing by insulation, it will be
necessary to mount a thermostat-controlled heating tape
round the condensate drain pipe.
Optimal operation is achieved by mounting a
connector piece Ø 160 mm in each outlet of the
GES Energy and tighten them with the supplied
collar bands.
While operating there will be a low pressure in
the unit it will therefor be neccesary to make
sure that the height difference is min. 50 mm
to the water in the siphon.
